Next, a specific example of a screen presented to the user in the process of step S4 described above will be described. FIG. 3 is a diagram showing a specific example of a screen presented to the user in the process of step S4 described above.

  The target file size set by the user when executing the transmission job or the storage job is shown in the area A1.

  The current file size of the scanned image data is shown in area A2.

  Since the current file size exceeds the target file size, a message “The target file size has been exceeded. Please select a reduction method.” Is displayed in the area A3.

  Under the area A3, as a method for designating a page to be subjected to data size reduction processing, an “all” button B1, a “designated page only” button B2, and an “other than designated page” button B3 are displayed.

  On the right side of the “other than specified page” button B3, a “send as it is” button B4 is provided for forcibly executing the job even if the target file size is exceeded.

  Below the buttons B1 to B4, the preview image PA of each page is displayed together with the page number PN, and the data size of each page is shown in the area A4 below each preview image PA.

  The navigation button B5 is used to display preview images for the fifth and subsequent pages.

  By presenting such a screen to the user, the user can easily select a page to be reduced.

  The specific example of the screen presented to the user has been described above in the process of step S4.

[Screen example 2]
Next, a specific example of a screen presented to the user in the processing of steps S6 and S7 described above will be described. FIG. 4 is a diagram showing a specific example of a screen presented to the user in the processing of steps S6 and S7 described above.

  The screen described below is a screen example when the “only specified page” button B2 is pressed in step S4.

  In this screen example, check boxes CB1, CB4, and CB7 for specifying whether or not to reduce each page are displayed under the preview image PA of each page and the area A4 indicating the data size of each page. .

  Below the check boxes CB1, CB4, and CB7, check boxes CB2, CB3, CB5, CB6, CB8, and CB9 for designating reduction means are shown.

  In the example of this figure, it is specified to perform the size reduction process by reducing the resolution for the image data of the first page.

  Further, the reduction process is not performed for the second page and the third page.

  The image data of the fourth page is designated to be subjected to size reduction processing by reducing the image quality.

  Note that size reduction may be performed by applying both resolution reduction processing and image quality reduction processing.

  The specific example of the screen presented to the user has been described above in the processing of steps S6 and S7.

[effect]
The image forming apparatus 20 according to the embodiment of the present invention has the following effects.

  (1) Since the target file size can be specified for each execution of the job, the user can flexibly execute the job by setting a larger target size for image data with a large number of pages than when setting the target uniformly. Can be executed.

  (2) When executing the save job, the user can determine the target file size in consideration of the purpose of use of the image data to be saved.

  (3) Since the user can set the target file size in consideration of the total number of pages of the image data, the user can reduce the size so that the size is the same for each page regardless of the total number of pages. Can be applied.

  (4) Since it is possible to specify whether or not the size reduction processing is performed in units of pages, it is possible to protect important pages from resolution degradation and image quality degradation due to size reduction.

  (5) In addition to the method of specifying the pages to be subjected to the size reduction process, by providing a method for specifying the pages to be protected from the size reduction process, the user can reduce the size when there are many pages to be reduced. It is possible to reduce the trouble of specifying many pages to be performed.

  (6) Since the user can select only a page having a large data size and perform size reduction, the overall file size can be reduced without reducing the image quality of other pages.

  (7) If the file size of the image data obtained by scanning is within the target file size, the job can be executed without performing the size reduction process, so that the time until the job is completed can be shortened.
