A mode selection screen consisting of "X" and "network" is displayed. From this, select "Inset destination format registration".
Next, the inset format is set. The embedding destination format may be obtained from an external manuscript by scanner input, or may be obtained from an incoming mail or accumulated file.

At this time, it is necessary to specify a fitting frame on the document format. To specify the fitting frame, an image of this document format is displayed on the touch panel display 301, and for this display, the upper left end and the lower right end of the area to be the fitting frame are designated by the pen 404, or the coordinates are designated. Done by

Next, the operation after the document format registration will be described.

First, "inset processing" is selected from the initial screen shown in FIG. Then, as shown in Fig. 7, the screen shows "Received Mail", "Received FAX Message", "Scanner Input".
The display switches to the selection screen for the "stored file" embedded image. When any item is selected by the user from these, if the selection item is other than "Scanner Input", the following selection screen will be displayed to prompt you to select which image in the selection item to be the inset image. It The fit image is determined by the user designating the fit image on the selection screen. For example, received mail and received F
In the case of the AX message, the reception time or the like is specified, and in the case of the accumulated file, the file name is specified to specify the inset image. Also, if there is no information on the selected item, or if it is detected that no document is set on the document platen even though scanner input is selected, a warning indicating that there is no embedded image is displayed. Display as a message and return to the selection screen before the inset image.

The inset image selected in this manner is displayed on the display 301 of the operation panel 103. After that, the user confirms the fitted image through this display, and if there is no problem, indicates through the operation panel 103 that the confirmation is completed. After completion of this confirmation, the display is switched to the selection screen of the original document format to be fitted. Figure 8
Shows an example of a screen for selecting the original document format to be fitted. In the same figure, the shaded area is the fitting frame. The document format to be fitted is selected by designating the number given to each format at the time of registration.
Also, the size of the recording paper is designated on this selection screen.

After the document format is selected, the image fitting process is started immediately. This processing flow is shown in FIGS. 9 to 11.

First, the print area detection unit 503 performs the processing for detecting the print area (image area to be fitted) from the confirmed document image as follows. First, as shown in FIG. 12, the original image is projected in the horizontal direction (step 901), and high frequency components are removed (step 90).
2) Detect the positions where the image is interrupted by more than the set threshold value (consecutive blank portions), and determine the vertical distance between these detected positions as the width in the height direction of the print area (step 903). ). The threshold value is preset by the user in the range of 1 to 20 mm, for example. If the user does not specify, 8 mm is set as the initial value.

Thereafter, a position where the projection result (the number of added pixels) is lower than the threshold value for detecting the line spacing is detected as a line spacing position in the print area, and this result is held (step 90).
4).

At this time, the original is tilted and the scanner 101
The following diagonal correction can be performed in consideration of the case of being set to. In this case, first, the original is rotated 10 degrees in the clockwise direction around the center of gravity of the original and projected horizontally (steps 905 and 906), and after removing high frequency components (step 907), the same as above. Positions where the image is interrupted by more than a set threshold value are detected, and the vertical distance between these positions is obtained as the width in the height direction of the print area (step 908). Subsequently, the line spacing position in the print area is detected and held (step 90).
9). After that, the projection angle is returned by 2 degrees in the reverse rotation direction (step 910), the projection is taken in the same manner, and the width in the height direction of the print area is obtained each time, and the line spacing position in the print area is detected at the same time. And hold this (step 906-
910). This process is repeated 10 times (step 911). After that, the widths in the height direction of the print areas obtained in each cycle are compared, and the minimum value among them is determined as the correct width in the height direction of the print area, and at the same time, the projection angle at that time is corrected. The angle is determined, and the line position detected when the projection is performed at this projection angle is set as the correct line position (step 912).

Next, the original image is projected in the vertical direction (step 913). This projection is performed with the corrected projection angle if the projection angle was corrected in the previous step. After that, high-frequency components are removed (step 914), the width of the print area in the horizontal direction is obtained from the projection result (step 915), and the projection result (additional pixel number) in the print area is used for character space detection. A position lower than the threshold value is detected as the space between characters (step 916).

The print area detected as described above is displayed on the display 301 on the operation panel 103 as shown in FIG.
Is displayed (step 917), and confirmation by the user is performed (step 918). As a result, if the print area is inappropriate, the user specifies the area by specifying the coordinates of the end points of the correct area from the operation panel 103 (step 919). After this, a preset margin area is added around the detected print area.

Thereafter, the print area position size adjusting unit 505
Is started, and the size and position of the print area are adjusted as follows.

First, the vertical and horizontal sizes of the print area are compared with the vertical and horizontal sizes of the fitting frame of the document format. The size of the fitting frame of the document format is automatically determined by the fitting frame position size management unit 504 according to the size of the recording paper.

A concrete example of this size comparison is shown in FIG.
In this comparison, in each of the vertical and horizontal directions, the scaling is performed in the vertical and horizontal directions with respect to the print area according to the smaller value of the scaling ratio (steps 1001, 1002, 1003). Figure 1
In the example of 4, the magnification ratio is X / x in the horizontal direction,
In the vertical direction, the scaling factor is Y / y. X> x, Y <
Since the value of the scaling ratio is smaller for Y / y from the relationship of y, the scaling ratio of Y / y is used for scaling the print area in the vertical and horizontal directions.

However, at that time, if the scaling factor is 0.7 or less or 1.41 or more (steps 1004 and 1005),
A warning is issued to the user through the display 301 of the operation panel 103 (step 1006), and the scaling is performed with the same scaling factor (steps 1007, 100).
8) Whether to request the user to determine the scaling factor (step 1
The user is requested to select one of the methods (009 to 1011) and whether to expand / compress the detected lines or characters (steps 1012 to 1018).

Expansion between lines or characters is performed by inserting a blank line having a width designated by the user in the center of the space between lines or characters (step 101).
5, 1017). Similarly, compression is performed by deleting a line having a width designated by the user from the center of the space between lines or characters (steps 1016, 1018).

Next, as shown in FIG. 15, for example, the print area 151 after the size change and the fitting frame 152 of the original format.
With respect to the direction in which a large margin portion is generated between and, the margin length L1 is compared with the side length L2 in the same direction of the fitting frame, and in this comparison, the margin length L1 is the fitting frame 152. If 50% or more of the length L2 of the side in the same direction (steps 1019, 1020), this ratio is just
The line spacing or character spacing is adjusted so as to be 50% (steps 1021, 1022). This completes the size adjustment.

After the size adjustment, the print area is moved within the fitting frame (steps 1023 and 1024) so that the top edge (or left edge) of the print area coincides with the top edge (or left edge) of the fit frame (steps 1023 and 1024), and then the fitting is performed. The print area is again moved within the fitting frame so that the center of gravity of the print area matches the center of gravity of the print area (steps 1025, 10).
26). This completes the position adjustment.

When the above size adjustment and position adjustment are completed, the fitting result is displayed on the display 301 of the operation panel 103 (step 1027). If the user determines from this display that the fit state of the print area is inappropriate (step 1028), the user resets the magnification of the print area, compresses / expands the character spacing or line spacing, and prints through the operation panel 103. The area is rotated or translated (steps 1029 to 1035). At this time, the rotation angle of the rotational movement and the distance of the parallel movement are designated from the operation panel (steps 1032 and 1034). The travel distance is given in units of 1 mm in each direction.

Thereafter, the image information of the print area is stored in the HDD 210 or ODD 209 as required (steps 1035, 1036).

As described above, the image information of the print area obtained by performing the fitting process or the image information of the print area accumulated in the HDD 210 or ODD 209 is printed and recorded on the recording paper by the print recording unit 506.

Thus, according to the multifunctional copying apparatus of this embodiment, it is possible to automatically and collectively perform the detection of the print area, which is the inset image area, the size adjustment and the position adjustment of the print area from the original image. It is possible to significantly reduce the operation load on the user. Further, by automating the size adjustment and the position adjustment of the print area, it is possible to always obtain an aesthetically optimum image fitting result irrespective of the operation skill of the user.

Further, when the print area is detected from the original image by projection, the optimum projection angle is detected by performing projection from a plurality of angles, so that even if the original is set to be tilted from the beginning, The print area can be accurately detected by automatically correcting the inclination.

Further, according to the present embodiment, the positions of the lines and the characters of the document can be detected, so that the size of the printing area can be adjusted without changing the size of the characters themselves by adjusting the distance between the lines and the characters. Thus, it is possible to prevent the situation where the characters are too small to be seen when the print area is reduced at a high magnification.

Further, in the present embodiment, by internally managing the information regarding the original format of the embedding destination, only the image to be embedded therein can be stored alone, and the amount of accumulated information can be saved.

In addition to reducing the operation load, it is possible to always obtain an aesthetically optimal image fitting result regardless of the operation skill of the user.
