[Explanation of Second Embodiment (FIGS. 7 to 11)] Next, an example of an image processing apparatus having a function of pasting image data and displaying the pasted image will be described.

Conventionally, in an image processing apparatus of this type, when an image is pasted on a page, the entire image is stored without changing the image size even if the image is pasted out of a displayable editing area. FIG. 7 illustrates this, FIG. 7 (a) shows a pasted image, 200 is a pasted image,
FIG. 7B shows an example in which a pasted image is pasted on a page, wherein 202 is a page, 204 is a displayable edit area, and 206 is a pasted image pasted.

However, in the above-described conventional example, since an image in an area that is not displayed is also stored together, the data size increases, and there is a problem that it takes time to store and read the image.

The configuration of the present embodiment for solving this problem will be described below.

FIG. 8 is a flowchart showing an example of a control procedure by the CPU 10. FIG. 9 is a diagram showing an example of a display screen in this embodiment.

In step S201, an edit page window 224 is displayed on the display screen 223, and in step S202, an arrow cursor 225 is displayed at a predetermined position on the display screen 223, for example, at the lower right corner. FIG. 9A shows the state at this time. Next, in step S203, information is input from the pointing device 6, and an editable display range frame 226 is displayed on the edit page window in step S204 in accordance with the input coordinate salary increase. FIG. 9B shows the state at this time.

Information is input from the pointing device 6 in step S205, and an image is pasted in the editable display range frame in step S206 according to the input coordinate information. FIG. 9C shows the state at this time, and reference numeral 227 denotes an attached image. Then, in step S207, of the pasted images, the images outside the editable displayable range frame 226 are deleted.

FIG. 10 shows a pasted image in the present embodiment, and FIG.
Reference numeral 8 denotes a pasted image area, 229 denotes a pasted image, FIG. 11 denotes a pasted image from which an image outside the editable display range frame has been deleted, 230 denotes a pasted image area, and 231 denotes a pasted image.

As described above, since the image outside the editable display range frame is automatically deleted from the storage target, the image data size is reduced, and the storage and reading can be performed quickly.

In the second embodiment, the image outside the editable display range frame is deleted when the image is pasted. However, when the image is pasted, the image is within the editable display range frame. Even when the editable display range frame is protruded by editing such as rotation, the image outside the frame may be deleted. Further, the shape of the editable displayable range frame may be a circle, an ellipse, or a polygon, and the size of the edit page itself can be regarded as the editable displayable range frame without having to create the editable displayable range frame.

As described above, according to the second embodiment, since the configuration is as described above, there is an effect that an image that is outside the editable display range frame can be automatically deleted.

Next, an embodiment applied to an image processing apparatus having an editing function of cutting a part of an image read from a scanner or the like and pasting the cut image will be described.

Conventionally, in this type of image processing apparatus, when an image is read from a scanner on a page being edited, and when the image is to be pasted, only a part of the image read from the scanner is cut out and pasted on an edit page. I was

However, since only a part of the image read from the scanner can be cut, if you want to paste a different part of the image, after finishing pasting, read the image from the scanner again and cut out the image of the part you want to paste,
There was a problem that it had to be pasted on the edit page.

Therefore, the image processing apparatus of this embodiment operates so that a plurality of images can be cut out at a time from the image read from the scanner and pasted to the edit page.

FIG. 12 is a flowchart showing an example of a control procedure by the CPU 10.

In step S301, the original image display window 320 is displayed on the display screen 319, and the original image 321 read by the image scanner 3 or the original image read from the external storage device is displayed in the original image display window 320, and step S302 is performed.
The arrow cursor 322 is displayed at a predetermined position on the display screen 319, for example, at the lower right corner. FIG. 13A shows the state at this time. In step S303, it is determined whether or not a paste instruction has been input from the keyboard 5 as a key. If there is no paste instruction, the process is terminated. If there is a paste execution instruction, the flow proceeds to step S304.

In step S304, the pasted image display window 323 is displayed, and the pasted image 324 read by the image scanner 3 or the pasted image 324 read from the external storage device is displayed in the pasted image display window 323. FIG. 13B shows the state at this time.

Thereafter, the process proceeds to the actual pasting process. When the pasting position information is input from the pointing device 6 in step S310, the first cut image is displayed in the original image display window 320 in step S311. FIG. 13 (e) shows this state.

Next, in step S312, it is determined whether or not the pasting is completed, that is, whether all the cut images have been pasted, or whether all the cut images have not yet been pasted but the pasting process is to be terminated. As a result, if the process is repeated, the process returns to step S310, the image cut out next to the image just pasted is pasted, and if it is to be ended, the process is terminated as it is. (F) of FIG. 13 (2) is a diagram showing a state after the processing of FIG. 2 is performed without terminating the process after the first time.

In this way, since a plurality of images can be cut and pasted at once, there is no need to read, cut, and paste images from a scanner or the like for each pasting process. Can be performed quickly and easily.

In the above-described embodiment, the shapes of the cutout areas 325 and 326 are rectangular, but it is clear that the shape of the cutout area frame can be freely selected, such as a circle, an ellipse, or a polygon. FIG. 14 shows an example of this case. The control procedure by the CPU 10 is the same as that of the above-described embodiment, and the description is omitted.

In the embodiment described above, there is an effect that a plurality of images can be cut and the cut images can be pasted by reading the image once from a scanner or the like at the time of pasting.

The present invention is particularly useful when applied to an image processing apparatus having an editing function such as pasting a cut-out display image or rotating, symmetrically moving, or hatching a display image.

Conventionally, in this type of image processing apparatus, when cutting an image, a certain range of the image is designated, and all the images within the range are cut. Further, when pasting the cut image, a position of the image is designated, and the whole cut image is pasted at that position. Further, when rotating an image within a certain range, all the images within the designated range are rotated. Also, when images within a certain range are targeted, all the images within the specified range are symmetric. Further, when hatching is applied to an image within a certain range, hatching is applied to all the images within a specified range.

In other words, all images in the specified range are rotated, symmetric, hatched, cut, etc., and as a result, the same processing as other images is performed even for images that you do not want to edit. There was a problem that would.

Therefore, in this embodiment, when editing the image,
An instruction not to edit an image within a certain range can be given.
