Abstract

PURPOSE:To recognize the whole image of an image and to easily designate an edit object area by displaying the whole image of the image on a display device. CONSTITUTION:When the resolution of image data is higher than the resolution of an image displaying means 19, the image size of the image data is reduced by thinning the data by means of a first display control means 15, and the whole image of the image data is displayed on an image displaying means 19. The edit object area designated from the whole image by an area designating means 12 is made to correspond to 1 bit 1 pixel by a second display control means 13, restored to the data of the image size in which the data are not thinned out, and thereafter, displayed on the image displaying means 19. Consequently, the edit in a bit unit can be executed. Thus, the whole image of the image can be easily recognized, and simultaneously, the edit object area can be easily designated.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image editing processing device that specifies a predetermined area of image data displayed on the screen of a display device and edits the image data of that area.

[Prior Art] Conventionally, in such a device, when image data of a certain resolution is displayed on the screen of a display device of a different resolution, one bit of the image data is divided into one pixel of the screen size of the display device. When editing text, the image data displayed on the screen of the display device is scrolled and the data in the target area is displayed. In the device, when displaying image data of n resolution on the screen of ice play gef having a lower resolution, for example, image data with a resolution of 300 dots/inch is displayed on a display HIi2 with a resolution of 72 dots/inch. Even if the image data is 20 cm square, it will be displayed on the screen of the display device as an image approximately 4.2 times larger than 84 cm square, and the user will be able to scroll the image data displayed on the screen up and down and left and right. Otherwise, it would be impossible to grasp the entire image, and it would take time to find the editing area.Additionally, when there was a large amount of data, the scrolling speed would become extremely slow, reducing work efficiency. In addition, since only a portion of the image data is displayed on the screen, it is difficult to specify a specific area to be edited, and editing memory is allocated to areas other than the area to be edited, requiring a large amount of memory. I needed it.

The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide an image editing processing device that can easily recognize the entire image and easily specify an area to be edited.

In the present invention, the image size of the image data set in the image file is compared with the screen size of an image display means such as a CRT, and the image data is adjusted so that the entire image of the image data is displayed on the screen in one poem. a first display control means for processing, an area specifying means such as a mouse for specifying a desired editing target area from the display area of the image data displayed on the screen of the image display means; a second display control means for displaying the image data of the Moeki Satoshi collection target area on at least a part of the screen by associating 1 pixel of the edited target area with 1 pixel of the screen size; If the resolution of the image data is higher than the resolution of the image display means,
The first display control means reduces the image size of the image data by data thinning, the entire image of the image data is displayed on the image display means, and the area specifying means -
[The area to be edited specified from the entire image is returned to image-sized data in which 1 bit is associated with 1 pixel by the second display control means and is not thinned out, and then displayed on the image display means.] Therefore, it is possible to edit in units of pins 1 and up.

[Example] An example of the present invention will be described in detail based on the drawings of FIGS. 1 to 3.

FIG. 1 is a block diagram showing a schematic configuration of a character input device according to the present invention. In the figure, a keyboard 11 and a mouse 12 connected to the keyboard 11 input various data and commands including the editing target area, and the control unit (
The processor 13 executes predetermined deductions, processing, etc. according to the program corresponding to the input command. External record V
The device (disk HiE2) 14 stores concentrated data (expenditures), programs, and a group of dictionaries for converting flat names into gray characters. The image editing processing device 15 thins out the image data according to the reduction ratio of the image data calculated by the processor 13, and displays the thinned out image data as a whole on a CRT 19, which will be described later. The image memory (storage unit) 16 is comprised of a RAM, and temporarily stores image data of a designated area to be edited.

Next, the processing operation of the image editing processing device will be explained based on the flowchart 1- in FIG.

Before performing the operation shown in FIG. 2, the user uses the mouse 12 to specify an area in which the entire image will be displayed. Specify the desired coordinate values of the lower and upper left of the center of the screen in the display coordinate system to be within the left half of the rectangular area, and open a window that displays the entire image. Next, the processor 13 extracts the image size from the imported image size (step 101),
The screen size of the rectangular area A displayed on the screen 9 is compared with the image size, and it is determined whether the entire image can be displayed within the rectangular area (step 102). If the entire image cannot be displayed within the rectangular area, the reduction ratio at which the image data will fit within the rectangular area is calculated from the screen size of the rectangular area and the image size (step 103). Then, once the reduction rate is determined,
The image editing device 15 thins out the image data according to the reduction ratio, and the processor 13 thins the CRT drive circuit 18.
is controlled so that the entire image of the thinned out image is displayed within the rectangular area of the CRT 19 (step 104). Next, when the user operates the mouse 12 to specify an editing target area from the entire image displayed on the CRT 19 (step 105), the processor 13 creates an editing window for the editing target area on the CRT. B is shown in Figure 3 (
Listen and edit image memory (storage unit) 1 as shown in b).
6 (step 106), and the above editing target area is stored. The image editing device associates the image data in the target area with one bit and one pixel, and the associated image data is displayed in the editing window of the CRTl 9 (step 107). Furthermore, mouse 12
The area specified by is identified by determining which pixel 1 in the image data the positions of the upper left point P and lower right point O specified by the mouse above correspond to on the CRT19, and the correspondence is determined. Pi 1~ and Pi 1-
Image data within the range between is extracted and displayed.

This allows the user to edit the image data using the editing window of the CRT 19 (step 108).

If the entire image can be displayed in the rectangular area A of the CRT in step 102, the process proceeds to step 108;
Desired image data can be edited from the entire image.

Next, step 10 to determine whether there is another editing area.
9) If there is an editing area, the editing area is specified using the mouse 12 in step 105, and the above-described operation is repeated until there are no more editing areas to be edited.

Therefore, in the present invention, the image data is reduced, the entire image is displayed on the CRT, and when editing, the image data of the specified target area can be displayed in correspondence with 1 bit and 1 pixel. There is no need to scroll through the editing area as in the past, and the entire image can be recognized at a glance, and bit-by-bit editing is also possible, reducing editing time and increasing operational efficiency. Furthermore, since the area to be edited can be specified from the entire image, it is only necessary to allocate the image memory for editing to the area to be edited, thereby saving the storage space of the memory.

In the embodiment, the image data is reduced to display the entire image on the CRT, but this is not the only option. If the image size of the image is smaller than the screen size of the display area, the entire screen of the display area may be displayed. It is also possible to enlarge the image data so that the entire image is displayed.

〔Effect of the invention〕

As described above, in the present invention, since the entire image can be displayed on the display device, the entire image can be easily recognized and the area to be edited can be easily specified.
