The scanning function (image scanning function) is a function that scans an image of a document and generates image data. The fax function is a function for transmitting and receiving image data via a public telephone line or the like.

The multifunction device 1 (an example of an image processing device) includes a reading unit 11 (an example of an executing unit) for a scanning function and a printing unit 12 (an example of an executing unit) for a printing function.

The method of reading the image by the reading unit 11 may be an ADF (Auto Document Feeder) method of reading the image of the sheet while transporting the sheet, or an FB (FB) for reading the image of the sheet placed on the contact glass. Flat Bed) method may be used.

Further, the multifunction device 1 includes an operation panel 13. The operation panel 13 is provided with an operation unit 14 and a display unit 15.

The operation unit 14 (an example of a reception unit) includes operation keys (for example, a start key and a return key). When the operation key is operated, the operation is accepted by the operation unit 14, and a signal (data) corresponding to the content of the operation is output from the operation panel 13.

The display unit 15 is composed of, for example, a liquid crystal display.

The operation unit 14 and the display unit 15 may constitute a touch panel. Images such as various information and operation buttons are displayed on the display unit 15 constituting the touch panel. When the user presses an operation button displayed on the display unit 15 (touch operation), the operation is accepted by the operation unit 14, and a signal (data) corresponding to the content of the operation is output from the operation panel 13. Will be done. In the following, a case where the operation unit 14 and the display unit 15 form a touch panel will be taken up.

Further, the multifunction device 1 includes a LAN interface (I / F) 16, a FAX interface (I / F) 17, and a control unit 18.

The LAN interface 16 (an example of a reception unit) is an interface for connecting to the LAN 2.

The FAX interface 17 (an example of a fax communication unit) is an interface for connecting to a public telephone line used for fax communication, and includes a modem having a built-in NCU (Network Control Unit) and the like.

The control unit 18 includes an ASIC (Application Specific Integrated Circuit) 21, a ROM (Read Only Memory) 22, and a RAM (Random Access Memory) 23.

In addition to the ROM 22 and the RAM 23, the ASIC 21 is connected to a reading unit 11, a printing unit 12, an operating unit 14, a display unit 15, a LAN interface 16, and a fax interface 17.

The ASIC 21 has a built-in CPU 24 (an example of a control unit). A signal or the like output from the operation panel 13 is input to the ASIC 21. The CPU 24 executes a program stored in the ROM 22 based on a signal input to the ASIC 21, a reading unit 11, a printing unit 12, an operation unit 14, a display unit 15, a LAN interface 16, and a fax interface 17. Control each part including.

The ROM 22 is composed of a rewritable non-volatile memory such as a flash memory. The ROM 22 stores a program executed by the CPU 24, various data, and the like.

The RAM 23 (an example of a storage unit) is a volatile memory such as a DRAM (Dynamic Random Access Memory), and is used as a work area when the CPU 24 executes a program.

<Job parallel processing>
In the multifunction device 1, the image data may be used for a plurality of jobs with different functions. For example, image data may be used for both print jobs with the print function and fax jobs with the fax function. In this case, the CPU 24 of the ASIC 21 executes the job parallel processing shown in FIG.

In the job parallel processing, the CPU 24 controls, for example, the reading unit 11 to execute a scan job for reading an image of a document by a scanning function. By executing the scan job, the image data is generated by the reading unit 11, and the CPU 24 receives the input of the image data from the reading unit 11 (S11). In response to this, the CPU 24 stores the input image data as original data in the RAM 23. As a result, the original data is held in the RAM 23.

Next, the CPU 24 controls the image processing circuit 25 (see FIG. 1) included in the ASIC 21 to generate intermediate data from the original data (S12), and stores the intermediate data in the RAM 23. The intermediate data is processing according to the settings related to each job, and is data obtained by applying common processing to the original data in generating output data output by each of a plurality of jobs. As an example of the intermediate data, there is data of a "2in1" image in which images over two pages of original data are aggregated on one page. In addition to that, the intermediate data includes "4in1" image data, which is a collection of four pages of original data on one page, data that has been processed to reduce the resolution of the original data, and original data. On the other hand, data that has been processed to be reduced, data that has been subjected to monochrome conversion processing with respect to the original color data, and the like can be mentioned. The setting related to the job may be performed by the operation of the operation unit 14, or may be performed by the operation of the external terminal when the image data is input from the external terminal via the LAN interface 16. .. Further, in the following, the case where the image data processing is performed by the image processing circuit 25 is taken as an example, but a part of the image data processing may be executed by the program processing executed by the CPU 24.

After that, the CPU 24 controls the image processing circuit 25 according to the setting related to the first job to process the intermediate data into the output data for the first job (S13). Then, the CPU 24 executes the first job and outputs the output data for the first job (S14). For example, the data of the "2in1" image, which is intermediate data, is compressed by a predetermined first compression method, and the output data generated by the compression is output to a sheet by executing a print job. The first compression method is, for example, a Mode 9 compression method. The Mode9 compression method is a combination of a run-length compression method and a front-line comparison compression method that compresses data according to whether the data in one line in the width direction of the image is the same as the data in the previous line. be.

Further, in parallel with the processing to the output data for the first job, the CPU 24 processes the intermediate data into the output data for the second job according to the setting related to the second job (S15). Then, the CPU 24 executes the second job and outputs the output data for the second job (S16). For example, the data of the "2in1" image, which is intermediate data, is compressed by a predetermined second compression method, and the output data generated by the compression is transmitted from the FAX interface 17 to the fax terminal of the other party by executing a fax job. The second compression method is, for example, an MH (Modified Huffman) compression method.

The process of processing the intermediate data into the output data for the first job (process 1) and the process of processing the intermediate data into the output data for the second job (process 2) are executed in parallel. The concept of "execution of process 1 and process 2 in parallel" includes at least one of the following (1) or (2).
(1) The processing circuit 1 for executing the processing 1 and the processing circuit 2 for executing the processing 2 are independently provided separately, and the processing 1 and the processing 2 are simultaneously executed by the respective circuits. The processing circuit refers to a dedicated image processing circuit, a CPU, and the like.
(2) Using a common processing circuit, processing 1 and processing 2 are alternately executed little by little .

When the CPU 24 determines that both the first job and the second job have been completed (S17: YES), the CPU 24 determines the size of the output data (data capacity) for the first job and the size of the output data for the second job. Sum and compare the total data size with the size of the intermediate data (S18). Then, the CPU 24 stores the result of the comparison in the RAM 23.

After that, the CPU 24 erases the intermediate data, the output data for the first job, and the output data for the second job from the RAM 23 (S19, S20). The original data is left in the RAM 23 and is continuously retained. Then, the CPU 24 sets the data holding time T1 in the timer (S21), and starts measuring the elapsed time after both the first job and the second job are completed.

The initial value of the data retention time T1 is set to, for example, 5 minutes. The data retention time T1 is provided with an addition condition, and when the addition condition is satisfied, the addition time corresponding to the addition condition is added to the initial value of the data retention time T1.

For example, as shown in FIG. 3, an addition time of 30 minutes is set as an addition condition that the free capacity of the RAM 23 is equal to or more than a predetermined amount. The first job or the second job is a fax job, and an addition time of one hour is set as an addition condition that the image data (original data) received by fax is printed on the sheet on the FAX interface 17. An addition time of 30 minutes is set as an addition condition that the job is not executed as intended. When the job is not executed as intended, for example, because the automatic continuation mode is set so that the execution of the print job is not interrupted due to a sheet size error, etc., the sheet size is different from the sheet size set in the print job. Is stored in the tray of the sheet supplier, but the image is printed on a sheet of a size different from the setting. In the addition condition that the toner extension mode is set, the addition time for one day is set. The toner extension mode is a mode provided in the multifunction device 1 having a configuration in which the printing method by the printing unit 12 is an electrophotographic method, and even if the remaining amount of toner in the printing unit 12 drops to a predetermined low level, the toner extension mode is provided. This mode uses up the remaining toner. In the toner extension mode, the image printed on the sheet may be faint due to the low amount of toner remaining.

<Data retention processing>
After setting the data retention time T1, the CPU 24 of the ASIC 21 executes the data retention process shown in FIG. 4 at regular intervals.

In the data holding process, the CPU 24 determines whether or not the original data is held in the RAM 23 (S31). As described above, immediately after the first job and the second job are completed and the intermediate data, the output data for the first job, and the output data for the second job are erased from the RAM 23, the original data is stored in the RAM 23. Is retained. Here, in the present invention, "erasing data" refers to releasing the usage state of the storage unit (RAM 23) by the data and making it possible to overwrite the data with other data.

When the CPU 24 determines that the original data is held in the RAM 23 (S31: YES), whether or not the data holding time T1 has elapsed since both the first job and the second job are completed, that is, the data holding. It is determined whether or not the timer for which the time T1 is set has timed up (S32). When the CPU 24 determines that the data retention time T1 has not elapsed (S32: NO), the CPU 24 ends the data retention process. When a certain time (one cycle) has elapsed from the start of the completed data retention process, the CPU 24 newly executes the data retention process.

When it is determined that the data holding time T1 has elapsed since both the first job and the second job are completed (S32: YES), the CPU 24 reads the result of the data size comparison executed in the job parallel processing from the RAM 23. Then, from the result of the data size comparison, the CPU 24 determines whether or not the intermediate data is equal to or less than the total data size (the sum of the size of the output data for the first job and the size of the output data for the second job). Judgment (S33).

When the CPU 24 determines that the intermediate data is smaller than or equal to the total data size (S33: YES), the CPU 24 uses the same processing content as the processing from the original data to the intermediate data in the job parallel processing, and uses the original data held in the RAM 23. Process into intermediate data (S34). Then, the CPU 24 erases the original data from the RAM 23 (S35) and stores the intermediate data in the RAM 23. As a result, the intermediate data is held in the RAM 23 (S36).

On the other hand, when the CPU 24 determines that the intermediate data is larger than the total data size (S33: NO), the CPU 24 processes the original data in the job parallel processing into the output data for the first job and the output data for the second job. With the same processing content as above, the original data held in the RAM 23 is processed into output data for the first job and output data for the second job via intermediate data (S37). Then, the CPU 24 erases the original data from the RAM 23 (S38), and stores the output data for the first job and the output data for the second job in the RAM 23. As a result, the output data for the first job and the output data for the second job are held in the RAM 23 (S39).

After that, in the newly executed data holding process, the CPU 24 determines that the original data is not held in the RAM 23 (S31: NO). Then, the CPU 24 determines whether or not the intermediate data is held in the RAM 23 (S40).

When the CPU 24 determines that the intermediate data is held in the RAM 23 (S40: YES), the CPU 24 determines whether or not a predetermined time T2 has elapsed since the intermediate data was stored in the RAM 23 (S41). When the CPU 24 determines that the predetermined time T2 has not elapsed (S41: NO), the CPU 24 ends the data holding process while the intermediate data is held in the RAM 23. Then, when a certain time (one cycle) has elapsed from the start of the data retention process that has ended, the CPU 24 newly executes the data retention process.

When the CPU 24 determines that the predetermined time T2 has elapsed since the intermediate data was stored in the RAM 23 (S41: YES), the CPU 24 outputs the output data for the first job and the output for the second job from the intermediate data in the job parallel processing. The intermediate data held in the RAM 23 is processed into the output data for the first job and the output data for the second job with the same processing contents as the processing to the data (S37). Then, the CPU 24 erases the intermediate data from the RAM 23 (S38), and stores the output data for the first job and the output data for the second job in the RAM 23. As a result, the output data for the first job and the output data for the second job are held in the RAM 23 (S39).

After that, in the state where the output data for the first job and the output data for the second job are held in the RAM 23, the CPU 24 holds both the original data and the intermediate data in the RAM 23 in the newly executed data holding process. It is determined that it is not (S31: NO, S40: NO). Then, the CPU 24 determines whether or not the predetermined time T3 has elapsed since the output data for the first job and the output data for the second job are stored in the RAM 23 (S42), and the predetermined time T3 has elapsed. If it is determined (S42: YES), the output data for the first job and the output data for the second job are erased from the RAM 23 (S43), and the data holding process is terminated. After that, the data holding process is not executed until the new original data is held in the RAM 23.

Before erasing the output data for the first job and the output data for the second job, the CPU 24 performs each of the thumbnail image related to the output data for the first job and the thumbnail image related to the output data for the second job. Data may be generated and each data may be stored in the RAM 23. By doing so, the thumbnail image related to the output data for the first job and the thumbnail image related to the output data for the second job can be displayed on the display unit 15, and the user can check the job history.

<Action effect>
As described above, when the image data related to the job is input, the original data (input data) which is the input image data is stored in the RAM 23. Then, the original data is processed into intermediate data, and the intermediate data is stored in the RAM 23. Further, the intermediate data is processed into output data output by executing the job, and the output data is stored in the RAM 23. At this point, the original data, the intermediate data, and the output data are held in the RAM 23. After that, when the execution of the job using the output data is completed, the intermediate data and the output data are erased from the RAM 23. This makes it possible to increase the free space of the RAM 23. Then, the state in which the original data is retained in the RAM 23 is maintained for a period until the data retention time T1 elapses after the execution of the job is completed. Therefore, within the data retention time T1, the user can change the setting related to the job and execute the job using the image data processed according to the changed setting. As a result, the degree of freedom in re-execution of the job can be guaranteed.

When the data retention time T1 elapses, the original data is processed into intermediate data or output data. As shown in FIG. 5, when the size of the intermediate data is less than or equal to the size of the output data (the total size of the output data for each job when multiple jobs are executed in parallel), The original data is processed into intermediate data. On the other hand, if the size of the intermediate data is larger than the size of the output data, the original data is processed into output data. Then, the intermediate data or the output data is stored in the RAM 23, and the original data is erased from the RAM 23. As a result, the intermediate data or the output data is held in the RAM 23, and the free space of the RAM 23 can be further increased while the opportunity to execute the job using the intermediate data or the output data can be secured.

Further, when the original data is processed into intermediate data and the intermediate data is stored in the RAM 23 instead of the original data, when a predetermined time T2 elapses from the storage, the intermediate data is output as shown in FIG. It is processed into data, the output data is stored in the RAM 23, and the intermediate data is erased from the RAM 23.

When the data retention time T1 is set in the timer and the free capacity of the RAM 23 is equal to or greater than a predetermined amount, the data retention time T1 is set to the time obtained by adding the addition time to the initial value. When there is a margin in the free space of the RAM 23, the original data is held in the RAM 23 for a long time, so that the user can change the settings related to the job to increase the period during which the job can be re-executed.

Even when a fax job of printing the original data received by fax on the fax interface 17 is executed, the data retention time T1 is set to the time obtained by adding the addition time to the initial value. In that case, the original data is image data owned by another person other than the user of the multifunction device 1, and is not owned by the user of the multifunction device 1, so that it is preferably held in the RAM 23 for a long time.

Also, if the job is not executed as intended, it is likely that the user will re-execute the job. In the toner extension mode, the image printed on the sheet may be faint due to the low toner level, and the user is likely to re-execute the job. Therefore, if the job is not executed as intended or the toner extension mode is set, the data retention time T1 is set to the time obtained by adding the addition time to the initial value so that the original data is retained for a long time. It is preferable to set it.

<Modification example>
Although one embodiment of the present invention has been described above, the present invention can also be implemented in other embodiments.

For example, in the above-described embodiment, the case where the first job and the second job are executed in parallel is taken up, but even when a single job is executed, the above-mentioned job parallel processing and data retention processing are performed. The same process should be executed. Further, three or more jobs may be executed in parallel.

The case where the CPU 24 executes each process has been described. However, the ASIC 21 may include a plurality of CPUs, and the plurality of CPUs may cooperate to execute each process.

The present invention is not limited to the multifunction device 1, and may be applied to an image processing device such as a printer having a printing function and a scanner having a scanning function.

In addition, various design changes can be made to the above-mentioned configuration within the scope of the matters described in the claims.
