  10, 11 and 12 are flowcharts showing the flow of the present invention. Hereinafter, the embodiment of the present invention will be described with reference to this flowchart and FIG.

  First, a case where the user performs the first analysis of the difference image using the present invention will be described.

  First, at 1001 in FIG. 10, the user retrieves the difference image data from the external storage device 210 in FIG. Next, at 1002 in FIG. 10, the extracted difference image data is read into the difference image data storage unit 222 in FIG. 2 via the image input unit 221 in FIG. Then, the processing proceeds to 1003 in FIG. 10, and the difference image data is displayed on the screen by the display unit 228 in FIG. Next, at 1004 in FIG. 10, the table editing unit 223 in FIG. 2 checks whether table data exists in the external storage device 210 in FIG. If table data exists, the process proceeds to 1006 in FIG. 10, and if not, the process proceeds to 1005 in FIG. 10 to create a new table. Next, at 1006 in FIG. 10, it is checked whether or not edit data relating to the difference image data read in the above exists in the table data. The table data is read from the external storage device 210 in FIG. 2 into the table storage unit 224 in FIG. 2, and the table data in the table storage unit 224 is checked in the table editing unit in FIG. As a result of checking, if edit data related to the read difference image data exists in the table data, the process proceeds to 1007 in FIG. 10, and if not, the process proceeds to 1008 in FIG. Here, since the first evaluation is performed, there is no editing data in the table. Therefore, the process proceeds to 1008 in FIG. In 1008 of FIG. 10, edit data is newly created. Next, at 1009 in FIG. 10, the difference image data path existing in the external storage device 210 in FIG. 2 and the edit data path newly created in 1008 in FIG. 10 are added to the table data (see FIG. 4). Next, in 1010 of FIG. 10, when the user presses the input button of FIG. 6, the user can input the cause of the difference portion or the like for the difference image data. The case where the user presses the display button in FIG. 6 will be described later. Next, at 1010 in FIG. Hereinafter, the input process will be described in detail. The user inputs the difference image data from the user input unit 225 of FIG. Initially, the screen of FIG. 6 is displayed to the user. In 1101 of FIG. 11, the user surrounds the difference with a rectangle (see FIG. 7). Here, the user may select a plurality of difference areas as rectangles or one difference area. As shown in FIG. 8, when the user makes a rectangular selection with respect to the difference area, another window is launched, and the user can input the cause of the difference portion. In another window, the difference area selected by the user in a rectangular shape is enlarged and displayed. Here, the enlargement and reduction can be arbitrarily changed by the user. Also, when another window is launched, the upper left and lower right coordinates of the rectangle are automatically entered in the difference area coordinate field of FIG. Furthermore, the user can not only input the cause of the difference but also delete it. For example, as shown in FIG. 8, when an input person is selected from the detailed information input person list, the comment (cause of the difference) of the input person selected in the list is displayed, which can be changed and deleted. Next, proceeding to 1102 in FIG. 11, the input data editing unit 224 in FIG. 2 associates the coordinates of the rectangle with the cause of the difference portion input by the user, and generates edit data. Next, proceeding to 1103 in FIG. 11, the edit data generated in 1102 in FIG. 11 is read into the edit data storage unit 227 in FIG. 2. Next, proceeding to 1104 in FIG. 11, the editing data read into the editing data storage unit 227 in 1103 in FIG. 11 is stored in the external storage device 210 in FIG. Next, the process proceeds to a display process 1013 in FIG. Hereinafter, the display process will be described in detail. Proceeding to 1201 in FIG. 12, the cause of the difference image and the difference portion is the same by associating the edit data existing in the external storage device 210 in FIG. 2 with the difference image data existing in the difference image data storage unit 222 in FIG. It is displayed on the screen (see FIG. 9). Here, a method for associating the difference image data with the editing data will be described. As shown in FIG. 8, the edit data holds rectangular coordinates. By comparing the coordinates of this rectangle with the coordinates of the difference image data, the location where the cause of the difference is displayed can be calculated, so that the difference image data and the edit data can be associated with each other.

  As described above, by using the present invention, the user can freely input the cause of the difference with respect to the difference image data with respect to a plurality of difference points or a single difference point. The difference image data can be viewed on the same screen. In addition, since the difference portion is surrounded by a rectangle, it is possible to intuitively recognize where the difference appears. Furthermore, as shown in FIG. 8, since the cause of the difference is displayed as a balloon from the difference portion surrounded by the rectangle, the difference portion and the cause of the difference corresponding thereto can be confirmed at a glance.

  Next, a case where the second analysis of the difference image is performed will be described. In the case of the second evaluation, the process proceeds from 1001 to 1010 in FIG. 10 as in the first evaluation. In FIG. 6, when the user presses the input button, the process proceeds in the same procedure as the first analysis. Here, a case where the user presses the display button in FIG. 6 and proceeds to 1011 in FIG. 10 will be described. Proceeding to 1201 in FIG. 12, the cause of the difference image and the difference portion is the same by associating the edit data existing in the external storage device 210 in FIG. 2 with the difference image data existing in the difference image data storage unit 222 in FIG. It is displayed on the screen (see FIG. 9).

  From the above, the user can see the cause of the difference portion input by himself for the first time. When the display button is pressed, it is effective in confirming what kind of difference cause has occurred for a certain difference image data.
