Description

  The present invention relates to a difference location display control program and the like.

  When replacing a system used for business in a company with a newly developed system, the screen output by the newly developed system is the same as the screen output by the currently operating system. There is a case where a function to check whether or not is required.

  In such a case, a technique is known in which a screen is regarded as an image, the images are compared, and different regions between the images are highlighted with a dotted line (see Patent Document 1). In this technique, there is a description that the control unit may perform control to enlarge and display the area of the dotted frame when the user selects the dotted frame.

  Note that the comparison of images results in a comparison between the pixels constituting the image.

JP 2011-49930 A

  However, in the prior art, even if different areas between images are highlighted and displayed, there is a problem that it is difficult for the user to specify a different portion because the pixels are too small. For example, there is a bar that displays a point where a difference exists vertically and horizontally, or a part that can be partially enlarged. However, if there are multiple conspicuous differences in one direction, it is difficult for the user to specify a detailed difference in another direction. There is a case.

  An object of one aspect is to make it easy for a user to specify a difference between images when comparing images in an old and new system.

  When the difference location display control program disclosed in the present application detects a difference between two image data, the difference location display control program displays a mark in association with at least one of the two image data. When selected, it causes the computer to execute a process of enlarging and displaying information indicating the content of the difference at the different location associated with the mark.

  According to one aspect, when comparing images in the new and old systems, it is possible to make it easier for the user to specify the difference between the images.

  Embodiments of a different point display control program, a different point display control method, and an information processing apparatus disclosed in the present application will be described below in detail with reference to the drawings. The present invention is not limited to the embodiments.

[Configuration of Information Processing Apparatus According to Embodiment]
FIG. 1 is a functional block diagram illustrating the configuration of the information processing apparatus according to the embodiment. When the information processing apparatus 1 according to the embodiment detects the difference between the two image data when comparing the two image data, the information processing apparatus 1 divides the entire image into predetermined fine areas, and the difference is within the divided areas. However, areas that have a small amount of difference, that is, areas that are difficult for the user to notice, are highlighted. As an example of the highlighting, there is an aspect in which a circle is included so as to include a difference. The information processing apparatus 1 determines whether or not a pointing device has entered the highlighted area. When the pointing device has entered, the information processing apparatus 1 displays thumbnails corresponding to the number of differences in the area. Note that the “thumbnail” here is not an image that is a reduction of the entire image, but an enlarged image that is cut out into a rectangle, for example, for areas that contain differences so that you can see at a glance what kind of image and content it is Refers to the image. When a certain thumbnail is selected, the information processing apparatus 1 further enlarges and displays the selected thumbnail.

  As illustrated in FIG. 1, the information processing apparatus 1 includes a control unit 10 and a storage unit 20.

  The control unit 10 has an internal memory for storing programs defining various processing procedures and control data, and executes various processes using these. And the control part 10 respond | corresponds to the electronic circuit of integrated circuits, such as ASIC (Application Specific Integrated Circuit) and FPGA (Field Programmable Gate Array), for example. Or the control part 10 respond | corresponds to electronic circuits, such as CPU (Central Processing Unit) and MPU (Micro Processing Unit). Further, the control unit 10 includes a comparison unit 11, a difference group creation unit 12, a thumbnailing setting unit 13, an identical display circle setting unit 14, and a difference highlighting display unit 15. The difference emphasis display unit 15 is an example of a first display unit and a second display unit.

  The storage unit 20 corresponds to a storage device such as a non-volatile semiconductor memory element such as a flash memory or a FRAM (registered trademark) (Ferroelectric Random Access Memory). The storage unit 20 includes a difference management table 21, a group ID management table 22, neighborhood distance value information 23, and limit value information 24.

  The difference management table 21 manages differences when two pieces of image data are compared. An example of the data structure of the difference management table 21 will be described later.

  The group ID management table 22 manages group IDs used when assigning thumbnail group IDs to the difference groups. The initial value of the group ID is “1”. The group ID management table 22 is used by the difference group creation unit 12. The neighborhood distance value information 23 is information that defines a limit value of distance (referred to as “neighbor distance value”) that regards the difference points as neighborhoods. An example of the neighborhood distance value information 23 is “4” indicating a pixel value. The neighborhood distance value information 23 is used by the difference group creation unit 12.

  The limit value information 24 includes a first limit value and a second limit value. The limit value information 24 in the first limit value is information that defines the limit value of the distance between the difference points regarded as one thumbnail group. An example of the first limit value is “75” indicating a pixel value. The first limit value is used by the thumbnail setting unit 13. The limit value information 24 in the second limit value is information that defines, for example, a limit value of the size of a circle for highlighting a difference point. An example of the second limit value is “50” indicating a pixel value. The second limit value is used by the same display circle setting unit 14.

  Here, the data structure of the difference management table 21 will be described with reference to FIG. FIG. 2 is a diagram illustrating an example of a data structure of the difference management table according to the embodiment. As shown in FIG. 2, the difference management table 21 stores a thumbnail group ID 21b, a thumbnail center coordinate 21c, and the same circle center coordinate 21d in association with the difference pixel coordinate 21a. The difference pixel coordinates 21a indicate pixel coordinates that are difference points. The thumbnail group ID 21b indicates the group ID of the thumbnail including the different pixel coordinates 21a. The thumbnail center coordinates 21c indicate the center coordinates of the thumbnail including the difference pixel coordinates 21a. The same circle center coordinate 21d indicates the center coordinate of the same circle including the difference pixel coordinate 21a. The same circle center coordinate 21d indicates the center coordinate of the circle when the different pixel coordinates 21a included in the plurality of thumbnails are highlighted with the same circle. Such a circle means a circle having a region with a small amount of difference that is difficult for the user to notice.

  As an example, when the difference pixel coordinate 21a is (X1, Y1), “1” is stored as the thumbnail group ID 21b, (1X, 1Y) is stored as the thumbnail center coordinate 21c, and (aX, aY) is stored as the same center circle coordinate 21d. doing.

  Returning to FIG. 1, the comparison unit 11 compares two pieces of image data. For example, the comparison unit 11 receives image data (current image) of a predetermined screen from the currently operating system. The comparison unit 11 receives image data (new image) of a screen having the same function as the predetermined screen from the new system. The comparison unit 11 compares the current image with the new image, and stores the coordinates of the pixel in which the difference has occurred in the difference pixel coordinate 21 a of the difference point management table 21.

  The difference group creation unit 12 creates a thumbnail group for the difference pixel coordinates. For example, based on the information stored in the difference management table 21, the difference group creation unit 12 determines whether or not the thumbnail group ID 21b of a predetermined difference pixel coordinate 21a is not set. If not set, the difference group creation unit 12 sets the group ID stored in the group ID management table 22 to the thumbnail group ID 21b, and adds 1 to the stored group ID. The difference group creation unit 12 uses the difference pixel coordinates 21 a of the difference point management table 21 to specify the difference pixel coordinates that are within the neighborhood distance value from the predetermined difference pixel coordinates. The difference group creation unit 12 specifies the minimum thumbnail group ID among the thumbnail group IDs of the specified difference pixel coordinates and the predetermined difference pixel coordinates. Then, the difference group creation unit 12 sets the specified thumbnail group ID for each thumbnail group ID. The difference group creation unit 12 repeats the difference group creation process by replacing the predetermined difference pixel coordinates 21a. The thumbnail group created here is a group of images displayed as thumbnails.

  The thumbnail setting unit 13 sets the center coordinates of the difference pixel coordinates included in the thumbnail group. For example, the thumbnailing setting unit 13 extracts the difference pixel coordinates 21 a of the same thumbnail group ID 21 b based on the information stored in the difference management table 21. The thumbnail setting unit 13 calculates the distance (maximum value) between the two most distant points of the extracted difference pixel coordinates 21a. If the maximum value is smaller than the first limit value, the thumbnail setting unit 13 calculates the center coordinates of the two most distant points, and sets the center coordinates as the thumbnail center coordinates 21c. Such center coordinates are the center coordinates of the images displayed as thumbnails. That is, regarding a plurality of difference points (difference points), if the degree of continuity between the difference points in the vicinity is smaller than a predetermined value, it is possible to display them together in one thumbnail.

  If the maximum value is larger than the first limit value, the thumbnail setting unit 13 does not set the center coordinates of the two most distant points as the thumbnail center coordinates 21c. This is because if it is larger than the first limit value, it is regarded as a difference group having a large amount of difference. That is, for a plurality of difference points, if the degree of continuity between adjacent difference points is larger than a predetermined value, the plurality of difference points themselves can be highlighted without being displayed as thumbnails.

  The same display circle setting unit 14 sets the center coordinates of the different pixel coordinates included in the same display circle. For example, the same display circle setting unit 14 acquires the center coordinates of each thumbnail group from the difference management table 21. The same display circle setting unit 14 calculates each distance between the center coordinates using the acquired center coordinates of each thumbnail group. The same display circle setting unit 14 compares each distance with the second limit value and determines whether there is a distance equal to or less than the second limit value. When there is a distance equal to or less than the second limit value, the same display circle setting unit 14 determines the midpoint coordinates of the center coordinates having the distance as the same circle center coordinates of the corresponding thumbnail group in the difference point management table 21. Set to 21d. This is to highlight two thumbnail groups having a distance equal to or smaller than the second limit value on the same circle.

  The difference highlighting display unit 15 highlights the difference points step by step. For example, the difference highlighting display unit 15 highlights the difference pixel coordinate 21a of the record in which the center coordinate is not set among the thumbnail center coordinates 21c stored in the difference management table 21 at the coordinate position on the new image. To do. As an example of highlighting, the color may be red or the line may be bold. The difference highlighting display unit 15 highlights a circle around the same circle center coordinate 21d of each thumbnail group in the difference management table 21. The radius of the circle is, for example, the distance of the difference pixel coordinate farthest from the same circle center coordinate 21d among the difference pixel coordinates 21a having the same circle center coordinate 21d. When the mouse cursor is on the highlighted circle, the difference highlighting display unit 15 specifies the ID 21b of the thumbnail group included in the circle stored in the difference management table 21. The difference highlighting unit 15 cuts out an image around the thumbnail center coordinate 21c corresponding to the specified thumbnail group ID 21b, makes it a thumbnail, and highlights the image. When the mouse cursor is on a thumbnail, the difference emphasis display unit 15 displays the thumbnail in an enlarged manner. As a result, the difference highlighting display unit 15 displays the difference points in a step-by-step manner, such as circle highlighting, thumbnail display, and thumbnail enlargement display. Can be identified. As a result, it is possible to prevent the user from overlooking each of a plurality of differences present at close positions.

[Difference display control process flowchart]
Next, a flowchart of the different location display control process according to the embodiment will be described with reference to FIGS. 3A to 3F.

  FIG. 3A is a diagram illustrating an overall flowchart of the difference location display control process according to the embodiment. As shown in FIG. 3A, the comparison unit 11 executes a comparison (difference finding) process (step S11). A detailed flowchart of the comparison process will be described later.

  Subsequently, the difference group creation unit 12 executes a difference group creation process (step S12). A detailed flowchart of the difference group creation process will be described later.

  Subsequently, the thumbnail setting unit 13 executes a thumbnail setting process (step S13). A detailed flowchart of the thumbnail setting process will be described later.

  Subsequently, the same display circle setting unit 14 executes the same display circle setting process (step S14). A detailed flowchart of the same display circle setting process will be described later.

  Then, the difference emphasis display unit 15 executes a difference emphasis display process (step S15). A detailed flowchart of the difference highlighting process will be described later.

  FIG. 3B is a diagram illustrating a flowchart of the comparison process. 3B will be described while showing a specific example of the difference management table 21 in FIG. 4A.

  As shown in FIG. 3B, the comparison unit 11 receives an image (current image) from the current system (step S21). The comparison unit 11 receives an image (new image) from the new system (step S22).

  The comparison unit 11 compares the current image and the new image, stores the coordinates of the pixel in which the difference has occurred in the difference management table 21 (step S23), and ends the comparison process. As shown in FIG. 4A, the coordinates of the pixel in which the difference has occurred are stored in the difference pixel coordinate 21 a of the difference point management table 21. The number of records is the number of pixels in which the difference has occurred, and the thumbnail group ID 21b is set to -1 indicating unset.

  FIG. 3C is a diagram illustrating a flowchart of the difference group creation process. Note that FIG. 3C will be described while showing a specific example of the difference management table 21 of FIG. 4B.

  The difference group creation unit 12 sets the number of records in the difference point management table 21 to NMAX (step S31). Then, the difference group creation unit 12 sets 1 to the variable N (step S32).

  The difference group creation unit 12 determines whether or not the variable N is equal to or less than NMAX (step S33). When it is determined that the variable N is equal to or less than NMAX (step S33; Yes), the difference group creation unit 12 acquires the Nth record from the difference point management table 12 (step S34).

  The difference group creation unit 12 determines whether or not the thumbnail group ID of the Nth record is not set (−1) (step S35). When it is determined that the thumbnail group ID of the Nth record is not set (−1) (step S35; Yes), the difference group creation unit 12 reads a value from the group ID management table 22. Then, the difference group creation unit 12 sets the read value as the thumbnail group ID 21b of the Nth record (step S36). The difference group creation unit 12 adds 1 to the group ID management table 22 (step S37). Then, the difference group creation unit 12 proceeds to step S38.

  On the other hand, when it is determined that the thumbnail group ID of the Nth record is not set (step S35; No), the difference group creation unit 12 proceeds to step S38.

  In step S38, the difference group creation unit 12 specifies all records in the difference point management table 21 having difference pixel coordinates 21a within the vicinity distance value from the difference pixel coordinates 21a of the Nth record as the vicinity records (step S38). . Here, the difference group creation unit 12 initializes a neighborhood group table (not shown) (step S39).

  The difference group creation unit 12 records all thumbnail group IDs 21b other than the unset value among the thumbnail group IDs 21b of the neighborhood record and the Nth record in the neighborhood group table (step S40). Then, the difference group creation unit 12 specifies the minimum value of the thumbnail group ID 21b in the neighborhood group table (step S41).

  The difference group creation unit 12 sets the specified minimum thumbnail group ID 21b as the thumbnail group ID of the record specified as the neighborhood group in the difference management table 21 (step S42). As shown in FIG. 4B, when the difference pixel coordinate 21a of the difference point management table 21 is (X1, Y1), (X2, Y2), (X6, Y6), “1” is set to the thumbnail group ID 21b. . That is, the difference pixel coordinates (X1, Y1), (X2, Y2), and (X6, Y6) are a group in which other difference pixel coordinates exist within the neighborhood distance value from any one of the difference pixel coordinates. . When the difference pixel coordinate 21a of the difference point management table 21 is (X3, Y3), (X4, Y4), (X5, Y5), “2” is set to the thumbnail group ID 21b. That is, the difference pixel coordinates (X3, Y3), (X4, Y4), and (X5, Y5) are a group in which other difference pixel coordinates exist within the neighborhood distance value from any one of the difference pixel coordinates.

  Then, the difference group creation unit 12 adds 1 to the variable N (step S43), and proceeds to step S33 to newly perform a difference group creation process for the Nth record.

  On the other hand, if the difference group creation unit 12 determines that the variable N is greater than NMAX (step S33; No), the difference group creation process ends.

  FIG. 3D is a flowchart of the thumbnail setting process. 3D will be described while showing a specific example of the difference management table 21 in FIG. 4C.

  The thumbnailing setting unit 13 acquires the number of thumbnail group IDs 21b set in the difference management table 21, and sets the acquired number as KM (step S51). In FIG. 4C, KM is “3”. Then, the thumbnailing setting unit 13 sets 1 to the variable L (step S52).

  The thumbnail setting unit 13 acquires all the records of the thumbnail group whose thumbnail group ID 21b is L from the difference management table 21 (step S53). The thumbnail setting unit 13 extracts the difference pixel coordinates 21a from all the acquired records, and calculates the distance (maximum value) between the two most distant coordinates (step S54).

  The thumbnail setting unit 13 determines whether or not the calculated maximum value is larger than the first limit value (step S55). If it is determined that the calculated maximum value is not greater than the first limit value (step S55; No), the coordinate of the midpoint between the two most distant coordinates is calculated (step S56). That is, the thumbnailing setting unit 13 regards a plurality of difference points (difference points) as a difference group (difference group that is difficult for the user to grasp) in which the degree of continuity between adjacent difference points is smaller than a predetermined value, Thumbnails can be displayed in association with any of the differences.

  The thumbnail setting unit 13 sets the calculated coordinates of the midpoint as the center coordinates of all the records of the thumbnail group whose thumbnail group ID 21b is L (step S57), and proceeds to step S58. As shown in FIG. 4C, (1X, 1Y) is set as the center coordinates of all the records of the thumbnail group whose thumbnail group ID 21b of the difference management table 21 is “1”. (2X, 2Y) is set as the center coordinates of all the records of the thumbnail group whose thumbnail group ID 21b in the difference management table 21 is “2”.

  On the other hand, when it is determined that the calculated maximum value is larger than the first limit value (difference that is easy for the user to grasp) (step S55; Yes), the thumbnail setting unit 13 determines the center of the two points that are farthest apart. Without setting the coordinates, the process proceeds to step S58. That is, the thumbnailing setting unit 13 regards a plurality of differences (difference points) as a difference group in which the degree of continuity between neighboring difference points is greater than a predetermined value, and displays a plurality of differences without displaying thumbnails. It becomes possible to highlight and display the point itself. As shown in FIG. 4C, “−1” is set to the center coordinates of all the records of the thumbnail group whose thumbnail group ID 21b of the difference management table 21 is “3”, and the center coordinates are not set.

  In step S58, the thumbnail setting unit 13 adds 1 to the variable L (step S58), and determines whether the variable L is larger than the number KM of the thumbnail group ID 21b (step S59). If it is determined that the variable L is smaller than KM (step S59; No), the thumbnailing setting unit 13 proceeds to step S53 in order to process the thumbnail group ID indicated by the next variable L.

  On the other hand, if it is determined that the variable L is greater than KM (step S59; Yes), the thumbnailing setting unit 13 ends the thumbnailing setting process.

  FIG. 3E is a flowchart of the same display circle setting process. 3E will be described while showing a specific example of the difference management table 21 in FIG. 4D.

  The same display circle setting unit 14 acquires the center coordinates of each thumbnail group from the difference management table 21 (step S61). The same display circle setting unit 14 calculates each distance between the acquired center coordinates (step S62). The same display circle setting unit 14 compares the calculated distances with the second limit value (step S63). This is because two thumbnail groups having a distance equal to or smaller than the second limit value are highlighted in the same circle.

  The same display circle setting unit 14 determines whether there is a combination of center coordinates of distances equal to or less than the second limit value (step S64). If it is determined that there is no combination of center coordinates of distances equal to or less than the second limit value (step S64; No), the same display circle setting unit 14 has no combination that should be the same display circle, so the same display circle The setting process ends.

  On the other hand, when it is determined that there is a combination of center coordinates of distances equal to or smaller than the second limit value (step S64; Yes), the same display circle setting unit 14 performs the following processing. That is, the same display circle setting unit 14 sets the midpoint coordinates of the center coordinates of the corresponding combination to the same circle center coordinates 21d of the thumbnail group records that are the corresponding combination of the difference management table 21 (step S65).

  As shown in FIG. 4D, (aX, aY) is set to the same circle center coordinate 21d of the thumbnail group record in which the thumbnail group ID 21b of the difference management table 21 is a combination of “1” and “2”. . That is, the distance between the thumbnail center coordinate 21c (1X, 1Y) of the thumbnail group ID 21b “1” and the thumbnail center coordinate 21c (2X, 2Y) of the thumbnail group ID 21b “2” is equal to or less than the second limit value. ing. Therefore, the same display circle setting unit 14 sets the midpoint coordinates (aX, aY) of the center coordinates of the combination as the same circle center coordinates 21d of the records of the combined thumbnail groups “1” and “2”. To do.

  And the same display circle setting part 14 complete | finishes the same display circle setting process.

  FIG. 3F is a diagram illustrating a flowchart of the difference emphasis display process.

  As shown in FIG. 3F, the difference highlighting display unit 15 highlights the difference pixel coordinate 21a of the record in which the thumbnail center coordinate 21c is not set on the difference point management table 21 at the coordinate position on the new image. (Step S71). Note that the difference highlighting display unit 15 may highlight the difference pixel coordinates 21a of the record in which the thumbnail center coordinates 21c are not set at the coordinate position on the current image. For example, the difference highlighting unit 15 sets a difference pixel coordinate in which the current image has a pixel value that is not a background color and the new image has a pixel value corresponding to the background color at the coordinate position on the new image. Display with dashed lines. The difference highlighting display unit 15 displays the difference pixel coordinates in the new image, not in the current image, in red at the coordinate position on the new image.

  Then, the difference highlighting unit 15 acquires the same circle center coordinate 21d of each thumbnail group on the difference management table 21, and sets the radius so that all the difference points are within the circle with the acquired coordinate as the center. The highlighted circle is displayed (step S72).

  The difference emphasis display unit 15 determines whether an end event has been acquired (step S73). When it is determined that the end event has not been acquired (step S73; No), the difference highlighting display unit 15 acquires the mouse cursor position (step S74).

  The difference emphasis display unit 15 determines whether or not the mouse cursor position is within the emphasis circle (step S75). When it is determined that the mouse cursor position is in the highlight circle (step S75; Yes), the difference highlighting display unit 15 has the center coordinates of the corresponding highlight circle as the same circle center coordinates 21d. Are specified (step S76). The difference highlighting display unit 15 specifies the thumbnail group ID 21b of all specified records (step S77).

  Then, the difference emphasis display unit 15 cuts out an image centering on the thumbnail center coordinates 21c corresponding to each identified thumbnail group ID 21b, enlarges the image to a predetermined size, and displays a thumbnail (step S78). And the difference emphasis display part 15 transfers to step S73.

  On the other hand, if it is determined that the mouse cursor position does not exist within the highlight circle (step S75; No), the difference highlighting display unit 15 determines whether the mouse cursor is present on the thumbnail (step S79). . If it is determined that the mouse cursor is present on the thumbnail (step S79; Yes), the difference highlighting display unit 15 further enlarges and displays the thumbnail (step S80). And the difference emphasis display part 15 transfers to step S73.

  When it is determined that the mouse cursor does not exist on the thumbnail (step S79; No), the difference highlighting display unit 15 proceeds to step S73.

  If it is determined in step S73 that an end event has been acquired (step S73; Yes), the difference emphasis display unit 15 ends the difference emphasis display process.

[Specific example of difference display control]
FIG. 5A to FIG. 5E are diagrams showing specific examples of the difference location display control. 5A to 5E, a specific example of the display control of the difference between the current image of the currently operating system (current system) and the new image of the new system (new system) will be described.

  As shown in FIG. 5A, the comparison unit 11 receives the current image of the current system and the new image of the new system, and displays the received current image and new image on the display. In FIG. 5A, the output image on the left is the output image of the current system, and the output image on the right is the output image of the new system. On the display, a “display comparison result” button and an “end” button are displayed. When the “Finish” button is pressed, the different location display control process is terminated.

  Here, when the “display comparison result” button is pressed, the comparison unit 11 compares the output image (current image) of the current system with the output image (new image) of the new system. The difference group creation unit 12 creates a thumbnail group for the difference pixel coordinates as a result of the comparison. The thumbnail setting unit 13 sets the center coordinates of the difference pixel coordinates included in the thumbnail group. The same display circle setting unit 14 sets the center coordinates of the different pixel coordinates included in the same display circle. The processing results of the difference group creation unit 12, the thumbnailing setting unit 13, and the same display circle setting unit 14 are shown in a specific example of the difference management table 21 in FIG. 4D, for example. Then, the difference highlighting display unit 15 highlights the difference pixel coordinate 21a of the record in which the thumbnail center coordinate 21c is not set on the difference point management table 21 at the coordinate position on the new image. That is, the difference emphasis display unit 15 highlights and displays the plurality of difference points when the degree of continuity between the adjacent difference points is greater than a predetermined value.

  As shown in FIG. 5B, the difference highlighting unit 15 sets a difference pixel coordinate in which the pixel value of the current image is different from the background color and the pixel value of the new image is the background color at the coordinate position on the new image. Displayed in bold broken lines. Here, a bold broken line d1 on the output image of the new system is a difference pixel coordinate in which the pixel value of the current image is different from the background color and the pixel value of the new image is the background color. On the other hand, the difference emphasis display unit 15 displays the difference pixel coordinates in which the pixel value of the current image is the background color and the pixel value of the new image is different from the background color in red at the coordinate position on the new image. Here, the bold non-dashed line d2 on the output image of the new system is a background color in the current image and a different pixel coordinate different from the background color in the new image. Then, on the display, a “detailed enlarged display” button and an “end” button are displayed. When the “Finish” button is pressed, the different location display control process is terminated.

  Here, when the “detailed enlarged display” button is pressed, the difference highlighting display unit 15 highlights the circle around the same circle center coordinate 21d of each thumbnail group of the difference management table 21.

  As shown in FIG. 5C, the difference highlighting display unit 15 highlights the circle d3. Here, it is assumed that two different parts to be thumbnailed are included in the circle d3 (d31, d32). That is, it is assumed that two values of the thumbnail group ID 21b having the center coordinate of the circle d3 as the same circle center coordinate 21d are included in the difference point management table 21.

  Here, when the mouse cursor is input in the area of the circle d3, the difference highlighting display unit 15 identifies and identifies all records in the difference management table 21 having the center coordinates of the circle d3 as the same circle center coordinates 21d. The thumbnail group ID 21b of all the records is specified. Then, the difference emphasis display unit 15 cuts out and enlarges an image around the thumbnail center coordinate 21c corresponding to each specified thumbnail group ID 21b, and converts the image into a thumbnail and highlights the image.

  As shown in FIG. 5D, the difference highlighting unit 15 cuts out images d31 and d32 around the thumbnail center coordinates 21c corresponding to the thumbnail group ID 21b, thumbnails them, and highlights them. Here, a thumbnail image s11 obtained by converting the image d31 into a thumbnail and a thumbnail image s12 obtained by converting the image d32 into a thumbnail are highlighted on the screen s1. As a result, thumbnails corresponding to the number of different locations are displayed for the different locations where the degree of continuity is smaller than the predetermined value, so that the user is not likely to overlook the different locations.

  Here, when one thumbnail is selected, the difference emphasis display unit 15 further enlarges and displays the selected thumbnail.

  As shown in FIG. 5E, when the thumbnail image s11 is selected, the selected thumbnail image s11 is enlarged, and an enlarged thumbnail image s110 is displayed. Thereby, since the thumbnails of the different places are enlarged and displayed for the different places where the degree of continuity is smaller than the predetermined value, the user is not likely to overlook the different places.

[Effect of Example]
In this manner, in the above-described embodiment, when the information processing apparatus 1 detects a difference between two image data, a mark is displayed in association with at least one of the two image data differences. When the mark is selected, the information processing apparatus 1 enlarges and displays information indicating the content of the difference at the different location associated with the mark. As a result, the information processing apparatus 1 can display in a stepwise manner the first area indicating roughly where the difference is, and the information of the individual differences included in the area. The user can specify the location to be confirmed in detail. As a result, it is possible to prevent the user from overlooking each of a plurality of differences present at close positions.

  Further, in the above-described embodiment, the information processing apparatus 1 displays a mark in association with any of the different portions if the degree of continuity between the different portions in the vicinity is smaller than a predetermined value. As a result, the information processing apparatus 1 can make the user notice a nearby difference using the mark.

  Further, in the above-described embodiment, the information processing apparatus 1 displays a plurality of different portions in a highlighted manner if the degree of continuity of the different portions within a predetermined distance is greater than a predetermined value. Thereby, the information processing apparatus 1 can make a user notice the difference part surely by highlighting and displaying the difference part over a wide range.

[Others]
Note that the components of the illustrated apparatus do not necessarily have to be physically configured as illustrated. In other words, the specific mode of device distribution / integration is not limited to that shown in the figure, and all or part of the device is functionally or physically distributed / integrated in an arbitrary unit according to various loads or usage conditions. Can be configured. For example, the comparison unit 11 and the difference group creation unit 12 may be integrated as one unit. Further, the difference management table 21, the group ID management table 22, the neighborhood distance value information 23, and the limit value information 24 may be connected as an external device of the information processing apparatus 1 via a network.

  The various processes described in the above embodiments can be realized by executing a program prepared in advance on a computer such as a personal computer or a workstation. Therefore, in the following, an example of a computer that executes a different point display control program that realizes the same function as the information processing apparatus 1 illustrated in FIG. 1 will be described. FIG. 6 is a diagram illustrating an example of a computer that executes a different location display control program.

  As illustrated in FIG. 6, the computer 200 includes a CPU 203 that executes various arithmetic processes, an input device 215 that receives input of data from the user, and a display control unit 207 that controls the display device 209. The computer 200 also includes a drive device 213 that reads a program and the like from a storage medium, and a communication control unit 217 that exchanges data with other computers via a network. The computer 200 also includes a memory 201 that temporarily stores various types of information and an HDD 205. The memory 201, CPU 203, HDD 205, display control unit 207, drive device 213, input device 215, and communication control unit 217 are connected by a bus 219.

  The drive device 213 is a device for the removable disk 211, for example. The HDD 205 stores a different location display control program 205a and different location display control processing related information 205b.

  The CPU 203 reads the different location display control program 205a, expands it in the memory 201, and executes it as a process. Such a process corresponds to each functional unit of the information processing apparatus 1. The different location display control processing related information 205 b corresponds to the difference management table 21, the group ID management table 22, the neighborhood distance value information 23, and the limit value information 24. For example, the removable disk 211 stores each piece of information such as the difference location display control program 205a.

  Note that the difference location display control program 205a is not necessarily stored in the HDD 205 from the beginning. For example, the program is stored in a “portable physical medium” such as a flexible disk (FD), a CD-ROM, a DVD disk, a magneto-optical disk, or an IC card inserted into the computer 200. Then, the computer 200 may read and execute the different location display control program 205a from these.
