Description

The present invention relates to a technique for reading an image of a document.

As an image reading device that reads an image of a manuscript and generates image data indicating the image, the generated image data is temporarily stored in a memory, and the image data saved when a request is received from another device is stored in another device. An image reader configured to transmit to the device is known (see, for example, Patent Document 1).

Japanese Unexamined Patent Publication No. 2001-238006

In the image reading device having the above configuration, setting values of various setting items necessary for reading the image are set, and the image is read according to the set setting values.
As a method of acquiring image data read with the set value desired by the user with another device, for example, each set value is set by the user performing a setting operation one by one in the image reading device, and reading is executed after the setting is completed. Then, there is a method of acquiring the generated image data from another device. However, in this method, the setting operation in the image reading device is troublesome.

Further, for example, when an image reading device is made to read an image with a preset setting value (hereinafter referred to as "specified setting value") for each setting item and image data is requested from another device, the user sets the image. There is a method of transmitting the value information so that the image reading device converts the image data according to the transmitted set value information and acquires the converted image data.

However, in this method, the specified set value at the time of scanning the original in the image reading device is set for each setting item so that the conversion according to the set value information can be appropriately performed regardless of the content of the set value information from the other device. It is necessary to set the maximum value among multiple set values that can be set. For example, when the setting item is the document size, it is necessary to set the maximum size among the plurality of document sizes that can be set as the specified setting value. Further, for example, when the setting item is a resolution, it is necessary to set the maximum resolution among a plurality of resolutions that can be set as the specified setting value. Further, for example, when the setting item is a setting of double-sided reading or single-sided reading, it is necessary to set double-sided reading as a specified set value.

In this way, the method of reading an image with the maximum value among the plurality of set values that can be set for each setting item as the specified set value increases the amount of data of the generated image data. Therefore, the amount of memory required for storing image data increases.

The present invention has been made in view of the above problems, and an object of the present invention is to suppress the amount of read image data while improving the usability and convenience of the user when reading an image.

The image reading device of the present invention includes a reading unit that reads an image of a document according to a set value for each of a plurality of types of setting items, a storage unit, an input unit, a display unit, and a communication unit capable of communicating with an information processing device. It is equipped with a control unit. The control unit executes acquisition processing, candidate display processing, selection reception processing, setting processing, reading processing, storage processing, and image data transmission processing.

In the acquisition process, at least one specific setting item among a plurality of types of setting items is set as a specific setting item, and for each specific setting item, information related to the setting value of the specific setting item that can be detected by the image reading device. This is the process of acquiring the setting-related information. In the candidate display process, among a plurality of setting values that can be set in the specific setting item, a plurality of candidate setting values that are a plurality of setting values according to the setting-related information acquired by the acquisition process are selected for each specific setting item. This is the process of displaying on the display unit. The selection acceptance process is a process of accepting a selection input of any one of a plurality of candidate setting values displayed by the candidate display process for each specific setting item via an input unit. The setting process is a process of setting the candidate setting value selected by the selection input received by the selection acceptance process as the setting value of the corresponding specific setting item. The scanning process is a process of causing a scanning unit to read an image of a document according to a set value for each of a plurality of types of setting items and generate image data indicating the scanned image. This scanning process is configured to scan the image of the original according to the set value set in the setting process for the specific setting item for which the set value is set in the setting process. The storage process is a process of storing the image data generated by the reading process in the storage unit. The image data transmission process is a process of transmitting the image data stored in the storage unit to the information processing device via the communication unit when the image data request is received from the information processing device via the communication unit.

According to such a configuration, for a specific setting item among a plurality of types of setting items, if there are a plurality of candidate setting values corresponding to the setting-related information, the plurality of candidate setting values are displayed. The user can select any one from the plurality of displayed candidate setting values, and by selecting any one of the candidate setting values, the image can be read according to the selected candidate setting value. Can be done.

That is, for the specific setting item, if there are a plurality of candidate setting values according to the setting-related information, the user can select any one of the plurality of candidate setting values, and thus the specific setting. Item setting values can be set easily and appropriately.

Therefore, according to the image reading device of the present invention, it is possible to suppress the amount of read image data while improving the usability and convenience of the user when reading the image.

The reading unit 15 is provided with an image sensor and is configured to be able to scan a document. The reading unit 15 executes a scan according to a set value for each of a plurality of types of setting items required for scanning in accordance with a control command from the control unit 11. The scanning unit 15 is configured to be capable of performing single-sided scanning that scans only one-sided images of the front and back sides of a document and double-sided scanning that scans both sides of an image individually.

That is, the scanning unit 15 can perform single-sided scanning on the originals placed on the platen 4. On the other hand, the scanning unit 15 can selectively execute both single-sided scanning and double-sided scanning for a document mounted on the ADF5 and conveyed by the ADF5. It should be noted that double-sided scanning may be performed on the originals placed on the platen 4.

The printing unit 16 has a printing mechanism of inkjet technology or electrophotographic technology, and can print an image on a sheet-shaped recording paper.
The platen original sensor 17 is configured to detect that an original is placed on the platen 4. Various specific configurations of the platen original sensor 17 can be considered. For example, the scanning unit 15 may be configured to detect the presence or absence of a document by scanning the entire document table 4, that is, the scanning unit 15 may function as a part of the document table document sensor 17.

Specifically, when the cover 3 is opened and then closed again by a cover open / close sensor (not shown), the reading unit 15 scans the entire document base 4, and as a result of scanning, the cover 3 faces the document table 4. When only the signal of the reflected light level indicating the surface (for example, white) is detected, it is determined that the document is not placed, and the signal of the level lower than the reflected light level indicating the surface facing the platen 4 is detected. If is detected, it may be determined that the manuscript is placed.

In addition to the presence or absence of the original, if the original is placed, the size of the original may be detected based on the result of scanning the document base 4 by the scanning unit 15. That is, the document base document sensor 17 may also have a function as the document size detection unit 19 described later.

The ADF document sensor 18 is configured to detect that a document has been placed on the mounting portion of the ADF 5.

It is configured to be able to detect information.

Further, the document size detection unit 19 also detects the size information of the document placed on the document table 4 even when the document table document sensor 17 detects that the document is placed on the document table 4. The document size detection unit 19 of the present embodiment scans a specific area of the document table 4 by the scanning unit 15 for the size information of the document placed on the document table 4, and detects the size information based on the scanning result. It is configured. Since the specific area scanned by the scanning unit 15 is a part of the entire platen 4, the document size may be uniquely determined to one specific size depending on the size and orientation of the document, or the document size may be different. In some cases, size information that is not uniquely determined and includes the possibility of multiple types of document sizes may be detected. In the present embodiment, for example, for an A4 size document, it is uniquely detected that the document is A4 size depending on the orientation in which it is placed. On the other hand, the A3 size document is configured so that it cannot be uniquely detected as being A3 size. When an A3 size document is placed on the platen 4, the document size detection unit 19 detects size information indicating that the document size may be at least A3 or A4 based on the scanning result.

Note that data communication between the image processing device 10 and the information processing device 30 is performed through LAN 9 as an example, and data communication may be possible via another communication medium or by another communication method.

(1-3) Description of Scan Function When the power of the image processing device 10 is turned on and started, a standby screen is displayed on the display 6. The user can select the function to be executed from the standby screen. When the scan function is selected on the standby screen, the scan menu screen is displayed on the display 6.

The scan menu screen is a screen in which more detailed first sub-function options of the scan function are arranged. The scan function is subdivided into a plurality of first sub-functions according to the output destination of the scan data. Specifically, it is subdivided into a plurality of first sub-functions such as scan-to-media, scan-to-PC, and scan-to-network. Of these, scan to PC is a function of transmitting scan data to an information processing device such as a personal computer or a tablet terminal. The information processing device 30 capable of transmitting scan data by scan-to-PC includes the information processing device 30 of the present embodiment. When scan to PC is selected on the scan menu screen, the processing method selection screen is displayed on the display 6.

The processing method selection screen is a screen in which options for how to transmit scan data to the information processing apparatus at the transmission destination are arranged. The scan to PC is subdivided into a plurality of functions according to the transmission mode of the scan data. Specifically, it is subdivided into a plurality of functions such as scan-to-file, scan-to-OCR, scan-to-image, scan-to-email attachment, and scan-to-memory storage. Then, when any one of the plurality of subdivided functions is selected by the user, a scan preparation screen corresponding to the selected function is displayed on the display 6. When scan to memory save is selected, the scan preparation screen 40 as illustrated in FIG. 3 is displayed.

The scan preparation screen 40 has a selection field display area 41. On the scan preparation screen 40, a scan execution button 45 is displayed in an area different from the selection field display area 41. In the selection field display area 41, at least one selection field may be displayed or the selection field may not be displayed at all, depending on the place where the document to be read is placed, the size of the document, and the like. FIG. 3 shows an example in which two selection fields 42 and 43 are displayed in the selection field display area 41.

The image reading system 1 of the present embodiment temporarily stores the scan data scanned by the image processing device 10 in the storage unit 12 of the image processing device 10, and later stores the stored scan data from the information processing device 30. It is configured so that the so-called pull scan to be acquired can be realized. Scan-to-memory storage is one of the functions for realizing pull-scan, and both the pull-scan control process of FIG. 9 and the scan data transmission process of FIG. 11 are processes for realizing scan-to-memory storage. Is.

Scan software, which is software for realizing pull scan, is also installed in the information processing device 30. This scan software includes a scan data acquisition processing program shown in FIG.

In the image processing device 10, as a plurality of types of setting items for which setting values are used when scanning a document, for example, a double-sided scan setting indicating which of a double-sided image and a single-sided image of the document is to be read, and a document size. There are settings, resolution settings, color settings, file format settings, brightness settings, contrast settings, etc.

Of these plurality of types of setting items, in the present embodiment, at least the double-sided scanning setting and the document size setting are specific setting items in which the set values are estimated before the start of scanning at the time of executing scan-to-memory storage.

At the start of scan-to-memory storage, first, a specific setting value is temporarily set for each of a plurality of types of setting items. The temporary setting means that the setting value of the corresponding setting item is only provisionally set, and the setting can be changed later by both the image processing device 10 and the information processing device 30. The temporarily set value is also referred to as a temporarily set value below.

After that, for the specific setting item, the corresponding setting-related information is acquired before the start of scanning, and one or more of the plurality of settable setting values according to the setting-related information is estimated. The setting-related information is information that can be detected by the image processing device 10 among the information related to the setting values of the corresponding specific setting items, and more specifically, the setting that is appropriate to be used for the scan to be executed from now on. Information that can estimate the value, or information that can estimate the setting value that the user may want to set in the scan to be performed.

In the present embodiment, regarding the double-sided scan setting, as the setting-related information, there is information indicating the detection state of the platen document sensor 17 and the ADF document sensor 18, that is, placement information. Regarding the document size setting, as the setting-related information, there is information indicating the detection state of the document size detection unit 19, that is, size information.

Then, for the specific setting item in which a plurality of setting values are estimated, a selection field in which the plurality of setting values are arranged as candidate setting values is displayed in the selection field display area 41 of the scan preparation screen 40. However, when a plurality of set values are estimated for a specific setting item, not all of the estimated plurality of set values are necessarily displayed in the selection column. In the present embodiment, for each specific setting item, a candidate setting value which is a setting value equal to or less than a specific maximum display number among a plurality of estimated setting values is displayed in the selection column. The maximum number of displays may be appropriately determined, and is, for example, 2 in the present embodiment.

The scan preparation screen 40 shown in FIG. 3 has a double-sided scan setting selection field 42, which is a selection field in which candidate setting values for double-sided scan settings are arranged, and a document size, which is a selection field in which candidate setting values for document size setting are arranged. An example in which the setting selection field 43 is displayed is shown.

When the number of estimated setting values is plural and equal to or less than the maximum display number, all the estimated setting values are displayed in the selection column as candidate setting values. On the other hand, when the number of estimated setting values exceeds the maximum display number, only the candidate setting values of the maximum display number among the estimated setting values are displayed. In this case, it may be determined by various methods which setting value is to be displayed and which setting value is not to be displayed. For example, based on the setting-related information, the suitability of being set as the set value for the scan to be executed may be determined, and the set value of the maximum number of displays may be selected and displayed in descending order of suitability. Further, for example, based on the setting-related information, the possibility that the user wants to set the scan to be executed may be determined, and the setting value of the maximum number of displays may be selected and displayed in descending order of the possibility.

For the specific setting items for which a plurality of candidate setting values are estimated and displayed, the maximum value among the displayed candidate setting values is tentatively set. Then, when any candidate setting value is selected by the user, the selected candidate setting value is finally set as the setting value of the specific setting item. When the scan is executed, the scan is performed according to the set value set. Note that this setting means that the setting value of the corresponding specific setting item is officially determined and the setting cannot be changed from the information processing apparatus 30 later.

For the specific setting item in which the estimated number of setting values is only one, the selection field is not displayed on the scan preparation screen 40, and the one setting value is set as the temporary setting value. When the scan is executed, the scan is performed according to the temporarily set value.

Regarding the double-sided scan setting, there are three types of set values that can be set, for example, "single-sided", "double-sided; long-sided binding", and "double-sided; short-sided binding". That is, it is possible to set whether to scan both sides or one side of the document as a scanning target, and further, in double-sided scanning, it is also possible to set the binding direction.

Regarding the set value of the double-sided scan setting, which is one of the specific setting items, in the present embodiment, the detection states of the platen document sensor 17 and the ADF document sensor 18 are acquired as setting-related information, and based on the detection states, the detection states are obtained. It is estimated whether either "double-sided" or "single-sided" is possible or should be "single-sided".

If the ADF document sensor 18 detects that a document is placed on the ADF 5, the user may perform either a double-sided scan or a single-sided scan. That is, the fact that the original is placed on the ADF 5 means that the user may desire to set both "double-sided" and "single-sided" as the setting values for the double-sided scan setting. Therefore, when it is detected by the ADF document sensor 18 that the document is placed on the ADF 5, two candidate setting values, "double-sided" and "single-sided", are estimated.

In this case, as illustrated in FIG. 3, a double-sided scan setting selection field 42 is displayed on the scan preparation screen 40, and a simple setting button indicating two estimated candidate setting values is displayed in the double-sided scan setting selection field 42. Specifically, the single-sided button 42a indicating "single-sided" among the candidate set values and the double-sided button 42b indicating "double-sided" among the candidate set values are displayed. The user can easily and efficiently set the setting value of the double-sided scan setting by selecting one of the simple setting buttons 42a and 42b displayed in the double-sided scan setting selection field 42.

Regarding the document size setting, as set values that can be set, for example, there are A3, A4, B5, B4, A5, 2L size, L size, postcard, A6 and the like. Regarding the setting value of the document size setting, which is one of the specific setting items, when the scan to memory save is executed, both when the document is placed on the ADF 5 and when the document is placed on the document stand 4. As the setting-related information, the detection state of the document size detection unit 19 is acquired and estimated based on the detection state.

Depending on the detection state of the document size detection unit 19, that is, the size and orientation of the mounted document, one document size may be uniquely specified, or the document size may not be uniquely specified. If the original size cannot be uniquely specified, a plurality of possible original sizes are estimated as the original size of the placed original based on the detection state. In other words, it can be said that these candidate setting values are setting values that the user is likely to want to set as the setting values for the document size setting.

When any of a plurality of set values that can be set as the document size is estimated based on the detection state of the document size detection unit 19, the scan preparation screen 40 shows an example as shown in FIG. The document size setting selection field 43 is displayed. In the document size setting selection field 43, a simple setting button for each candidate setting value equal to or less than the maximum display number among the estimated plurality of setting values is displayed. In FIG. 3, at least A3 and A4 are estimated as the setting values for the document size setting, and the A3 button 43a indicating A3 and the A4 button 43b indicating A4 are displayed as simple setting buttons in the document size setting selection field 43. An example is shown. The user can easily and efficiently set the setting value of the document size setting by selecting any of the simple setting buttons 43a and 43b displayed in the document size setting selection field 43.

When only one document size is uniquely specified based on the detection state of the document size detection unit 19, that one document size is provisionally set as the setting value of the document size setting. In this case, as illustrated in FIG. 6, the document size setting selection field 43 is not displayed on the scan preparation screen 40. Not limited to the document size setting, the selection field is not displayed on the scan preparation screen 40 for the specific setting item having one estimated candidate setting value.

(1-4) Execution Example of Pull Scan Next, a specific embodiment of the pull scan executed by the image reading system 1 of the present embodiment will be described with reference to FIGS. 3 to 7. When scan to memory saving is selected and started, for example, since it is detected that the document is placed on the ADF5, both sides and one side are estimated as the double-sided scan setting, and the document size detection unit 19 When the two types of document sizes A3 and A4 are estimated based on the detection state, the scan preparation screen 40 shown in FIG. 3 is displayed. The contents of the scan preparation screen 40 of FIG. 3 are as described above.

Immediately after the scan preparation screen 40 is displayed, the maximum value among the plurality of settable setting values is initially set as a temporary setting value for each of the setting values of the plurality of types of setting items. The initial temporary setting value in the double-sided scan setting is double-sided and long-side binding, and the initial temporary setting value in the document size setting is A3.

However, if the setting value is estimated for the specific setting item and a plurality of candidate setting values are displayed on the scan preparation screen 40, the temporary setting value is set as the maximum value among the plurality of candidate setting values for the specific setting item. Be changed.

When temporary setting values are set for both the double-sided scan setting and the original size setting, the selection fields 42 and 43 are referred to as "set later from the PC" indicating that the temporary setting values are set. A message is displayed.

If the scan execution button 45 is selected in this state, the document is scanned. During the scan execution, the execution screen 50 indicating that the scan is being executed is displayed. On the executing screen 50, the specific setting information 51 indicating the information of the setting value of the specific setting item is displayed. In this case, the scanning of the original is performed according to the provisionally set value for each of the setting items. Therefore, as the specific setting information 51, the message "Set later from the PC", which is information indicating that the scan is being executed with the temporary setting value for each specific setting item, is displayed. After the scan is completed, the scan data is stored in the storage unit 12.

When, for example, the double-sided button 42b is selected from the simple setting buttons 42a and 42b displayed in the double-sided scan setting selection field 42, both sides are set as the setting value of the double-sided scan setting. In this case, as shown in FIG. 3, in the double-sided scan setting selection field 42, the double-sided button 42b is highlighted, and the message "double-sided" indicating that both sides have been fully set is displayed. At this time, the main setting is to scan both sides of the original, and the main setting is not made up to the binding direction. As for the binding direction, a predetermined binding direction is temporarily set. In the present embodiment, the temporary setting value in the binding direction is "long-edge binding". Therefore, in the double-sided scan setting selection field 42, the message "(the binding direction will be set later from the PC)" indicating that a temporary setting value has been set for the binding direction is displayed.

Further, when, for example, the A4 button 43b is selected from the simple setting buttons 43a and 43b displayed in the document size setting selection field 43, A4 is actually set as the setting value for the document size setting. In this case, as shown in FIG. 3, in the document size setting selection field 43, the A4 button 43b is highlighted and the message "A4" indicating that A4 has been fully set is displayed.

When the scan execution button 45 is selected with both sides set as the double-sided scan setting and A4 set as the original size setting, the double-sided scan setting and the original size setting among the multiple types of setting items are selected. , The scan is executed according to the set value. Therefore, as the specific setting information 51 displayed on the executing screen 50, for the double-sided scan setting, the double-sided scan is executed because both sides are finally set, and a temporary setting value is set for the binding direction. Information indicating that the setting can be changed later from the information processing apparatus 30 is displayed. Regarding the document size setting, information indicating that A4 is set and scanning is being executed is displayed.

When, for example, the single-sided button 42a is selected from the simple setting buttons 42a and 42b displayed in the double-sided scan setting selection field 42, one side is set as the setting value of the double-sided scan setting. In this case, as shown in FIG. 4, in the double-sided scan setting selection field 42, the single-sided button 42a is highlighted, and the message "single-sided" indicating that one-sided is fully set is displayed.

Further, when, for example, the A3 button 43a is selected from the simple setting buttons 43a and 43b displayed in the document size setting selection field 43, A3 is actually set as the setting value for the document size setting. In this case, as shown in FIG. 4, in the document size setting selection field 43, the A3 button 43a is highlighted, and the message "A3" indicating that A3 has been fully set is displayed.

When the scan execution button 45 is selected with one side set as the double-sided scan setting and A3 set as the original size setting, the double-sided scan setting and the original size setting among the multiple types of setting items are selected. , The scan is executed according to the set value. Therefore, the specific setting information 51 displayed on the execution screen 50 has the contents shown in FIG. That is, as the specific setting information 51, for the double-sided scan setting, information indicating that single-sided scanning is being executed because one side is mainly set is displayed, and for the document size setting, A3 is mainly set. Information is displayed indicating that the scan is being performed.

If you want to execute a scan using a setting value that is not displayed in the selection field, you can select an area other than each simple setting button in the selection field. For example, when an area other than the simple setting buttons 42a and 42b in the double-sided scan setting selection field 42 is selected, the double-sided scan setting screen 60 shown in FIG. 5 is displayed.

On the double-sided scan setting screen 60, a setting value button 62 for each set value that can be selected in the double-sided scan setting and a temporary setting button 61 for setting an initial temporary setting value are displayed in an array. Then, by selecting any of the buttons, the setting value corresponding to that button is set. For example, when the setting value button 62 indicating the setting value of "double-sided scanning; long-edge binding document" is selected, both double-sided scanning and long-edge binding are set, and the screen returns to the scan preparation screen 40. When the set value is finally set on the double-sided scan setting screen 60, as shown in FIG. 5, the simple setting button is deleted from the double-sided scan setting selection field 42, and the double-sided scan setting selection field 42 is filled with double-sided scan and length. A message indicating that both edge bindings have been set is displayed.

Further, for example, on the scan preparation screen 40 shown in FIG. 4, when an area other than the simple setting buttons 43a and 43b in the document size setting selection field 43 is selected, the document size setting screen 65 shown in FIG. 5 is displayed. ..

On the document size setting screen 65, a setting value button 67 for all the setting values that can be selected in the document size setting and a temporary setting button 66 for setting an initial temporary setting value are displayed in an array. Then, by selecting any of the buttons, the setting value corresponding to that button is set. For example, when the setting value button 67 indicating the setting value of "B5" is selected, B5 is finally set as the setting value of the document size setting, and the screen returns to the scan preparation screen 40. When the set value is finally set on the document size setting screen 65, the simple setting button is deleted from the document size setting selection field 43 as shown in FIG. 5, and B5 is set in the document size setting selection field 43. A message indicating that this has been done is displayed.

Then, in a state where both double-sided scanning and long-edge binding are mainly set as the double-sided scanning setting via the double-sided scanning setting screen 60, and B5 is mainly set via the original size setting screen 65 as the original size setting. When the scan execution button 45 is selected, the scan is executed. In this case, as shown in FIG. 5, the execution screen 50 displays information indicating the set values set in both the double-sided scan setting and the document size setting as the specific setting information 51.

Next, another aspect of the pull scan will be described with reference to FIG. When scan-to-memory storage is started, for example, the ADF document sensor 18 detects that the document is placed on the ADF 5, and the document size is A4 based on the detection state of the document size detection unit 19. When it is uniquely specified, the scan preparation screen 40 shown in FIG. 6 is displayed.

On the scan preparation screen 40 of FIG. 6, the display content of the double-sided scan setting selection field 42 is the same as that of FIG. Further, it is the same as in FIG. 3 that the set value of the double-sided scan setting is the initial temporary set value. Therefore, when, for example, the single-sided button 42a is selected from the simple setting buttons 42a and 42b, one side is set as the setting value of the double-sided scan setting as shown in FIG.

On the other hand, regarding the document size setting, since it is uniquely specified that the document size is A4, A4 is temporarily set as the setting value for the document size setting. However, in this case, the original size setting selection field 43 is not displayed.

Then, as shown in FIG. 6, A4 is provisionally set because A4 is uniquely specified as the setting value of the document size setting, and the setting value of the double-sided scanning setting is finally set on one side by the user's selection operation. When the scan execution button 45 is selected, the scan is executed. Then, as shown in FIG. 6, the executing screen 50 displays that one side of the double-sided scan setting is set as the specific setting information 51, and the document size setting is scanned according to the temporary setting value. Is displayed.

Yet another aspect of the pull scan will be described with reference to FIG. When scan-to-memory storage is started, for example, the document is not detected by the ADF document sensor 18, but the document is detected by the platen document sensor 17, and the document is detected based on the detection state of the document size detection unit 19. When A3 and A4 are estimated as the sizes, the scan preparation screen 40 shown in FIG. 7 is displayed.

On the scan preparation screen 40 of FIG. 7, the display content of the document size setting selection field 43 is the same as that of FIG. Further, it is the same as in FIG. 3 that the set value of the document size setting is the initial temporary set value. Therefore, when, for example, the A4 button 43b is selected from the simple setting buttons 43a and 43b, A4 is actually set as the setting value for setting the document size, as shown in FIG.

On the other hand, regarding the double-sided scan setting, since it is detected that the original is placed on the platen 4, one side is set as the setting value of the double-sided scan setting. However, in this case, the double-sided scan setting selection field 42 is not displayed.

Here, in the present embodiment, when only one set value is uniquely specified based on the setting-related information, in principle, that one set value is provisionally set. However, as an exception, if the setting value of the double-sided scan setting is uniquely specified on one side due to the document placed on the platen 4, and the setting value of the double-sided scan setting is set to one side, the temporary setting is used. It is configured to be this setting.

As shown in FIG. 7, when one side is set as the setting value of the double-sided scan setting, and the scan execution button 45 is selected with the setting value of the document size setting set to A4 by the user's selection operation. , The scan is performed. Then, as shown in FIG. 7, on the executing screen 50, it is displayed that one side is set as the specific setting information 51 for the double-sided scan setting, and A4 is also set for the document size setting. Is displayed.

When scan-to-memory storage is executed in the image processing device 10, document scanning is executed, scan data is generated, and the scan data is stored in the storage unit 12. The user can acquire the stored scan data from the information processing device 30.

When the user activates the scan software in the information processing device 30 and performs a predetermined operation for executing the pull scan, the scan setting screen 80 shown in FIG. 8 is displayed on the display unit 34 of the information processing device 30. .. The scan setting screen 80 is a screen on which setting values of a plurality of types of setting items used for scanning can be set.

When the scan setting screen 80 is displayed for the first time after starting the scan software, the setting values of each setting item in the scan setting screen 80 are used when scanning the scan data stored in the storage unit 12 of the image processing device 10. The set value is displayed in the selected state. Further, the setting value used as the main setting value at the time of scanning is displayed so that the setting cannot be changed.

In FIG. 8, the document size selection box 81 for selecting the setting value of the document size setting is in a state in which A4 is set as the document size and cannot be changed to another size. This is because A4 was used as the present setting value for the document size setting when scanning the scan data stored in the storage unit 12 of the image processing device 10. On the other hand, regarding the setting values of the double-sided scan setting, since both the double-sided and the long-side binding were used as temporary setting values during scanning by the image processing apparatus 10, the temporary setting values used were selected. It is displayed. Since it is a temporary setting value, the setting value of the double-sided scan setting can be changed. For example, by switching the check mark in the binding direction check column 83, the binding direction can be changed to short-side binding. Further, for example, by unchecking the double-sided setting check box 82, it is possible to change to single-sided scanning.

When the scan button 86 displayed on the scan setting screen 80 is selected, a scan data request including user setting information indicating the setting value of each setting item set at that time is transmitted to the image processing device 10. .. As a result, the stored scan data in the image processing device 10 is converted according to the transmitted user setting information, and the converted scan data is transmitted from the image processing device 10.

Specifically, the conversion referred to here corresponds to the scan data corresponding to the setting value indicated by the user setting information when the setting value used at the time of scanning execution and the setting value indicated by the user setting information are different. It means converting to the content. That is, the scan data that has already been saved is converted so that the data has the same or the same contents as the scan data that should have been generated if the scan is executed with the set value indicated by the user setting information.

For example, when the setting value of the document size setting is A3 at the time of scanning, and then the information processing device 30 changes to A4 and the change to A4 is transmitted to the image processing device 10 as user setting information. , The image processing device 10 converts the stored scan data into A4 size scan data. Further, for example, when the setting value of the double-sided scan setting is double-sided at the time of scanning execution, and then the information processing device 30 changes to one side and the change to the single side is transmitted to the image processing device 10 as user setting information. The image processing device 10 converts the stored scan data into scan data composed of one-sided image data by removing one-sided image data of each original. In this way, by instructing the information processing apparatus 30 to change the scan data once generated to a different set value, it is possible to convert the scan data according to the instructed set value.

(1-5) Description of Each Process for Realizing Pull Scan Next, FIGS. 9 to 12 are used for the processes executed by the image processing device 10 and the information processing device 30 to realize the pull scan described above. I will explain.

First, the pull scan control process executed by the image processing apparatus 10 will be described with reference to FIG. When the scan-to-memory save is selected on the processing method selection screen described above, the control unit 11 of the image processing device 10 executes the pull scan control process shown in FIG.

When the control unit 11 of the image processing device 10 starts the pull scan control process of FIG. 9, the scan preparation screen 40 is displayed on the display 6 in S110. In S120, a specific setting value is temporarily set as an initial value for each of a plurality of types of setting items. Specifically, for the document size setting, which is one of the specific setting items, A3, which is the maximum value among the settable setting values, is temporarily set. For the double-sided scan setting, which is one of the specific setting items, the double-sided and long-side binding, which are the maximum values among the settable setting values, are temporarily set. For the setting values of each of the other setting items, the maximum value among the setting values that can be set is temporarily set. The maximum value referred to here means a set value that maximizes the amount of scan data. Therefore, for example, with respect to the set value of the resolution setting, the maximum value among the settable resolutions is temporarily set.

In S130, it is determined whether or not the original is placed on the ADF 5 or the original 4 based on the detection results of the original sensor 17 and the ADF original sensor 18. If no manuscript is placed on either the ADF 5 or the manuscript stand 4, the process proceeds to S150. If the original is placed on the ADF 5 or the platen 4, the process proceeds to S140.

In S140, the setting item display process is executed. The details of the setting item display process of S140 are as shown in FIG. As shown in FIG. 10, when the process shifts to the setting item display process, S310 determines whether or not the document is placed on the ADF5. If the manuscript is not placed on the ADF 5, that is, if it is placed on the platen 4, the process proceeds to S330. At this time, although not shown, one side is set as the setting value for the double-sided scan setting.

When the original is placed on the ADF 5, the double-sided scan setting selection field 42 is displayed in the selection field display area 41 of the scan preparation screen 40 in S320. At this time, the display content of the double-sided scan setting selection field 42 depends on the setting state of the set value of the double-sided scan setting. That is, when the set value is temporarily set, the simple setting buttons 42a and 42b are displayed and the temporary set value is set as shown in the double-sided scan setting selection field 42 illustrated in the upper left of FIG. A message is displayed indicating that you are. On the other hand, when either both sides or one side is set by the user, the simple setting button corresponding to the set value is set as illustrated in the lower left of FIG. 3 and the lower left of FIG. Is highlighted and a message indicating the set value is displayed.

In S330, it is determined whether or not the set value of the document size setting is a temporary set value. If it is set as the main set value instead of the temporary set value, the setting item display process ends and the process proceeds to S150. If it is a tentative set value, the process proceeds to S340. In S340, the detection result by the document size detection unit 19, that is, the size information is acquired.

In S350, based on the detection result acquired in S340, it is determined whether or not the size of the mounted document can be uniquely specified by one set value. If the original size can be uniquely specified, the process proceeds to S360. In S360, the setting value of the original size setting is temporarily set to the uniquely specified setting value. After the processing of S360, the process proceeds to S150.

If one document size cannot be uniquely specified in S350, the process proceeds to S370. In S370, the document size setting selection field 43 is displayed in the selection field display area 41 of the scan preparation screen 40. At this time, in the document size setting selection field 43, a simple selection button having a set value equal to or less than the maximum display number of the document sizes estimated based on the detection result is displayed. In S380, the maximum size of the original size displayed in S370 is temporarily set as a setting value for setting the original size. After the processing of S380, the process proceeds to S150.

Returning to FIG. 9, in S150, it is determined whether or not the user has operated the touch panel 7. If the touch panel 7 is not operated, the process returns to S130, and if the touch panel 7 is operated, the process proceeds to S160. In S160, it is determined whether or not the operation on the touch panel 7 performed by the user is an operation for setting the document size, that is, an operation on the document size setting selection field 43 in the scan preparation screen 40. If it is not an operation for setting the original size, the process proceeds to S180. If it is an operation for setting the original size, the process proceeds to S170.

In S170, the set value of the document size setting is mainly set to the set value selected by the user via the touch panel 7. In addition, the display content of the document size setting selection field 43 is also switched according to this setting. At this time, when the setting value is set by the user via the document size setting screen 65 shown in FIG. 5, as described in FIG. 5, the simple setting button is not set in the document size setting selection field 43. Display. After the processing of S170, the process returns to S130.

In S180, whether or not the operation on the touch panel 7 performed by the user is an operation for setting the setting value of the double-sided scan setting, that is, an operation on the double-sided scan setting selection field 42 in the scan preparation screen 40. to decide. If it is not an operation for setting the setting value of the double-sided scan setting, the process proceeds to S200. If the operation is for setting the setting value of the double-sided scan setting, the process proceeds to S190.

In S190, the set value of the double-sided scan setting is set to the set value selected by the user via the touch panel 7. At this time, when any of the simple setting buttons is selected, the setting value corresponding to the selected simple setting button is set for the double-sided or single-sided setting. However, in this case, the temporary setting state of the long side binding is maintained in the binding direction. On the other hand, when the setting value is set by the user via the double-sided scan setting screen 60 shown in FIG. 5, either the double-sided or single-sided setting or the binding direction setting is performed as described in FIG. This setting is also used, and the simple setting button is hidden in the double-sided scan setting selection field 42. After the processing of S190, the process returns to S130.

In S200, it is determined whether or not the scan execution button 45 in the scan preparation screen 40 is selected. If the scan execution button 45 is not selected, the process returns to S130. If the scan execution button 45 is selected, the process proceeds to S210.

In S210, the document is scanned. That is, the document is scanned according to the currently set values. After the scan is completed, the scan data generated by the scan of S210 is stored in the storage unit 12 in S220.

Next, the scan data transmission process executed by the image processing apparatus 10 will be described with reference to FIG. When the scan data is saved in the storage unit 12 due to the execution of the pull scan control process of FIG. 9, the control unit 11 of the image processing device 10 sets the saved scan data as a processing target and shows it in FIG. Execute the scan data transmission process.

When the control unit 11 of the image processing device 10 starts the scan data transmission process of FIG. 10, in S510, the control unit 11 receives the scan information request transmitted from the information processing device 30 via the communication unit 20. In S520, scan information indicating the set value of each setting item used when scanning the stored scan data is transmitted to the information processing device 30 via the communication unit 20. The scan information also includes information indicating whether the set value is a temporary set value or a main set value for each set value. That is, the temporary setting value is associated with the temporary setting information indicating that the temporary setting value is the temporary setting value. The setting information indicating that the setting value is set is associated with the setting value.

In S530, the scan data including the user setting information transmitted from the information processing device 30 is received via the communication unit 20. In S540, the scan data stored in the storage unit 12 is converted based on the received user setting information. However, if each setting value used at the time of scanning execution and each setting value indicated by the user setting information are exactly the same, no conversion is performed. In S550, the scan data converted by S540 is transmitted to the information processing device 30 via the communication unit 20. If the conversion is not performed in S540, the scan data stored in the storage unit 12 is transmitted to the information processing device 30 without conversion.

Next, the scan data acquisition process executed by the information processing apparatus 30 will be described with reference to FIG. The control unit 31 of the information processing apparatus 30 executes the scan data acquisition process shown in FIG. 12 when the scan software is started and a predetermined operation for executing the pull scan is performed.

When the control unit 31 of the information processing device 30 starts the scan data acquisition process of FIG. 12, the display unit 34 displays the scan setting screen 80 shown in FIG. 8 in S610. In S620, the scan information request is transmitted to the image processing device 10 via the communication unit 35. In S630, the scan information transmitted from the image processing device 10 is received via the communication unit 35.

In S640, the scan information reflection process is executed. This scan information reflection process is a process of matching the setting state of each setting item on the scan setting screen 80 with the setting value of each setting item indicated by the received scan information. Specifically, the setting value of each setting item on the scan setting screen 80 is the setting value indicated by the received scan information, that is, the setting used when scanning the scan data stored in the storage unit 12 of the image processing device 10. Makes the value selected. Further, the setting value used as the main setting value at the time of scanning is displayed in a state in which the setting cannot be changed.

S650 accepts the user's setting change operation for the scan setting screen 80. Then, when the scan button 86 is selected by the user, the scan data request including the user setting information is transmitted to the image processing device 10 via the communication unit 35 in S660. In S670, the scan data transmitted from the image processing device 10, that is, the scan data converted based on the user setting information transmitted in S660, is received via the communication unit 35.

(1-6) Effects of the Embodiment According to the embodiment described above, the following effects (1a) to (1e) are exhibited.
(1a) In the image processing apparatus 10, if there are a plurality of candidate setting values corresponding to the setting-related information for the specific setting item among the plurality of types of setting items, the plurality of candidate setting values are displayed. The user can select any one from the plurality of displayed candidate setting values, and by selecting any one of the candidate setting values, the image can be read according to the selected candidate setting value. Can be done. That is, for the specific setting item, if there are a plurality of candidate setting values according to the setting-related information, the user can select any one of the plurality of candidate setting values, and thus the specific setting. Item setting values can be set easily and appropriately.

Therefore, it is possible to suppress the amount of read image data while improving the usability and convenience of the user when reading the image.
(1b) When the set value is estimated to be larger than the maximum display number, the set value equal to or less than the maximum display number among the estimated plurality of set values is displayed on the scan preparation screen 40 as a candidate set value. Moreover, in the present embodiment, which of the estimated plurality of set values is to be displayed as the candidate set value is selected based on the setting-related information. For example, a setting of the maximum number of displays or less in descending order of suitability for being set as a setting value for the scan to be executed, or in order of high possibility that the user wants to set the setting value for the scan to be executed. The value is selected as the candidate setting value. Therefore, the user can easily and efficiently select the candidate set value.

(1c) If only one set value is uniquely specified as a result of estimation, that set value is provisionally set and used for scanning. Therefore, the user does not need to set the setting value for the specific setting item in which the setting value is uniquely specified. Moreover, for the specific setting item, an appropriate setting value is set and scanning is executed without requiring a user setting operation.

(1d) After the scan is executed, scan information indicating the set value of each setting item used for the scan is transmitted to the information processing device 30 in response to the request from the information processing device 30. Therefore, in the information processing device 30, the user can confirm what kind of set value the scan is performed in the image processing device 10 by looking at the scan setting screen 80 shown in FIG.

Further, the user can instruct a setting value different from the setting value used at the time of scanning via the scan setting screen 80. The content of the instruction for changing the set value by the user is transmitted to the image processing device 10 as user setting information. When the image processing device 10 receives the user setting information, the image processing device 10 converts the scan data according to the set value indicated by the user setting information, and transmits the converted scan data to the information processing device 30. Therefore, the user can easily acquire the scan data at the set value desired by the information processing apparatus 30.

(1e) Further, in the scan information transmitted from the image processing device 10 to the information processing device 30, information indicating whether the set value is a temporary set value or a main set value is associated with each set value. Be done. Then, in the information processing apparatus 30, the setting item for which the present setting value is set cannot be changed, and the setting item for which the temporary setting value is set can be changed. Therefore, the user can efficiently change the setting targeting the setting value whose setting can be changed.

[2. Other embodiments]
Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and can be implemented in various modifications.

(2-1) In the above embodiment, the specific setting items are the double-sided scan setting and the document size setting, but which of the plurality of types of setting items should be the specific setting item may be appropriately determined.

For example, the resolution at the time of scanning may be a specific setting item. In this case, as the setting-related information, for example, the free space that can store the scan data in the storage unit 12 is detected, and the resolution corresponding to the free space among a plurality of setting values that can be selected as the resolution according to the free space. At least one candidate setting value may be estimated.

More specifically, for example, it is assumed that there are four types of setting values that can be set as the resolution: 100 dpi, 200 dpi, 300 dpi, and 600 dpi. Then, as a result of detecting the free space of the storage unit 12, if the resolution is set to 600 dpi and the scan is executed, the scan data capacity may exceed the free space. If the resolution is set to 300 dpi or less, the scan data capacity may be exceeded. Is less than the free space. In this case, 300 dpi or less is estimated as the resolution candidate setting value. Then, among the estimated candidate setting values of 300 dpi or less, the candidate setting values of the maximum display number or less are selected and displayed in the selection column corresponding to the resolution in the scan preparation screen. When the maximum number of displays is 2, for example, 300 dpi and 200 dpi are displayed as candidate setting values so that either one can be selected.
