  The upper limit setting unit 905 sets the upper limit of the enlargement size or enlargement ratio of the image information in the selection range when enlarging the image information, based on the size of the display area of the display unit 711 and the size of the selection range. The enlargement size is the size (character size) of the image information after enlargement. The enlargement ratio is the size of image information after enlargement with respect to the size of image information before enlargement. The enlargement size and enlargement ratio are appropriately set based on the size of the image information before enlargement.

  Specifically, the upper limit setting unit 905 enlarges the size or enlargement ratio of the image information in the selection range when enlarging the image information in order to prevent the loss of image information when enlarging the image information in the selection range. Set an upper limit. The upper limit set by the upper limit setting unit 905 is displayed on the display unit 711 without omission of image information outside the selected range, for example, when image information in the selected range is enlarged most greatly after editing. A certain enlargement size or enlargement ratio is set. In the present embodiment, for example, the character size “10 pt (points)” is set as the upper limit of the character size that can be set when enlarging. In the present embodiment, as shown in FIG. 5, the character size “10 pt” is displayed on the display unit 711 without missing image information outside the selection range after the image information in the selection range has been greatly enlarged. This is the upper limit character size that can be displayed.

  The text conversion unit 906 converts the image information of the document G read by the document reading unit 20 into image information in a text format. The text conversion unit 906 uses, for example, an optical character recognition (OCR) function in order to recognize image information of the original G read by the original reading unit 20.

  The storage unit 80 stores a control program or the like when the editing unit 903 executes editing. The storage unit 80 enlarges the image information of the selection range, information for reducing the image information outside the selection range, information on an arrangement for easily positioning the image information outside the selection range, etc. Remember.

  Next, the operation of the image processing apparatus 100 in the present embodiment will be described using a flowchart. FIG. 6 is a flowchart for explaining the operation of the image processing apparatus 100 of the copier 1 according to the present invention. In the present embodiment, a flow for enlarging image information displayed on the display unit 711 will be described.

As shown in FIG. 6, in step ST1, the display control unit 904 causes the display unit 711 to display image information to be printed. The image information displayed on the display unit 711 is image information in a text format. The text image information is, for example, an image of the original G read by the original reading unit 20 converted into text image information by a text conversion unit 906 (for example, OCR).
In this embodiment, before enlarging the image information, as shown in FIGS. 3 and 4 (before editing), the character size of each character in the text-format image information displayed on the display unit 711 is “ 6pt (points) ".

  In step ST2, the range setting unit 901 sets the range selected in the image information by the user as the selection range of the image information. Specifically, the range setting unit 901 selects the range for enlarging the image information by the user after the “area designation” icon 110A is selected, so that the image information displayed on the display unit 711 is displayed. A selection range B (see FIG. 4) is set.

  In step ST3, the upper limit setting unit 905 selects the image information of the selection range when enlarging the image information based on the size of the display area of the display unit 711 and the size of the image information of the selection range selected by the range setting unit 901. Set the upper limit of the enlargement size (text size to enlarge). In the present embodiment, for example, the character size “10 pt” is set as the upper limit of the character size that can be set when enlarging. This is because the character size “10 pt” is displayed on the display unit 711 without missing image information outside the selected range after the image information in the selected range is enlarged as shown in FIG. This is because the upper limit is the character size that can be used.

  In step ST4, the content setting unit 902 selects the “enlargement / reduction” icon 110B by the user and the character size “8pt” in the icon 110F, so that the editing content in the selected range is “image information”. "Enlarge" and character size "8pt". Since the character size “8pt” selected by the user is equal to or less than the character size “10 pt” which is the upper limit of the enlargement size set by the upper limit setting unit 905, the content setting unit 902 "And the character size" 8pt "is set.

  In this embodiment, even if the user operates the icon 110F so that the value is larger than “10 pt” which is the upper limit of the enlargement size set by the upper limit setting unit 905, the user cannot The size cannot be a character size of a number larger than “10 pt”. That is, when the character size selected by the user is larger than “10 pt” which is the upper limit of the enlargement size set by the upper limit setting unit 905, the content setting unit 902 cannot set the editing content. This is because in this embodiment, if the character size is larger than the character size “10 pt” as the upper limit set by the upper limit setting unit 905, image information outside the selection range may be lost. is there.

  In step ST5, the editing unit 903 edits the image information of the selected range set by the range setting unit 901 based on the editing content set by the content setting unit 902. In the present embodiment, as shown in FIG. 4, the selection range B is set by the range setting unit 901. “Enlargement of image information” is set by the content setting unit 902, and the enlargement size of the image information is set to the character size “8pt”.

Here, the editing unit 903 enlarges the image information of the selection range B in which the image information is selected to the character size “8 pt” based on the text information held by the image information.
Further, the editing unit 903 reduces the character size outside the selection range B and adjusts the position of the character outside the selection range B. Specifically, the editing unit 903 does not overlap the image data outside the upper, lower, left, and right ranges of the selection range B after the image information of the selection range B is enlarged and does not overlap with the enlarged image information. The image information is edited so as to be displayed in the display area of the display unit 711.

  By reducing the image information outside the selection range or adjusting the position, the editing unit 903 adjusts the image information displayed in the display area of the display unit 711 so that there is no omission. In the present embodiment, as shown in FIG. 4, the editing unit 903 positions image information outside the selection range on the top, bottom, left, and right with respect to the selection range B after enlarging the image information of the selection range. It is divided into four image information blocks. Then, the editing unit 903 reduces each block and arranges each block within a range in which the divided blocks can be displayed in the display area of the display unit 711 without overlapping the image information of the selection range. It adjusts so that it may be located in the upper part of the left-hand side of a field.

  In step ST6, the display control unit 904 causes the display unit 711 to display the image information edited by the editing unit 903. As a result, the image information in the selection range can be enlarged, and the image information can be displayed without omission in portions outside the selection range. In this manner, the display unit 711 can display the image information of the selected range in an enlarged manner in a state where all display contents displayed in the display area of the display unit 711 before the enlargement are displayed. . As a result, the visibility of the image information after editing can be improved in the image information displayed on the display unit 711 as compared with the case where the image information in the image format is enlarged.

  In step ST7, the user operates the start key 73 to execute printing. Here, all the image information displayed on the display unit 711 including the enlarged image information is printed as it is displayed on the display unit 711. Thereafter, the process ends.

As described above, according to the image processing apparatus 100 of the present embodiment, for example, the following effects are achieved.
The image processing apparatus 100 according to the present embodiment is selected from a display unit 711 that can display text-format image information (image information in a state in which text information is held), and image information displayed in the display area of the display unit 711. A range setting unit 901 for setting the selected range as the selection range of the image information, a content setting unit 902 for setting the editing content of the image information in the selection range set by the range setting unit 901, and the image information in the selection range. The editing unit 903 that edits the image information in the selected range based on the text information to be edited and the editing content of the image information set by the content setting unit 902, and the image information edited by the editing unit 903 are displayed on the display unit 711. A display control unit 904. Therefore, the image information in the selection range can be edited based on the text information held by the image information. Thereby, the image information displayed on the display unit 711 can improve the visibility of the image information after being enlarged (after editing) in the selected range of image information.

  In the image processing apparatus 100 according to the present embodiment, the editing content set by the content setting unit 902 is enlargement of image information.
