Abstract

PURPOSE:To easily an smoothly display the image of a picture having high density on a display part and to display even the corrected areas of the picture and using a position information input part which designates the position of the picture image displayed on the display part. CONSTITUTION:A picture reading part 2 is prepared together with a display part 5, a memory part 4, an operating part 6 and a position information input part 7. Furthermore a processing part 3 is provided to store the picture image data given from the part 2 into the part 4 and then reads the image data out of the part 4 to display it at the part 5 based on the instructions of both parts 6 and 7. Thus the image of an optional part of the picture can be displayed easily and smoothly and also corrected. As a result, the operability of a picture display processor is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an image display processing device, and particularly to input 1 display, modification (insertion, deletion), and enlargement of high-density images.

The present invention relates to an image display processing device suitable for processing such as reduction.

[Conventional technology]

The image display processing device is used to edit the image, and for this purpose it is used to edit the image.

Processing such as display, modification (insertion, deletion), enlargement, reduction, etc. is required.

Conventionally, image display processing apparatuses have a limit to the size that can be displayed on a display unit, so when a large image with high density is displayed, it may not be possible to faithfully display the entire image on one screen. Therefore, in order to display a portion that requires correction or other processing, the image displayed on the screen must be moved vertically and horizontally to detect the necessary portion.

FIG. 3 is a block diagram of an example of a conventional image display processing device. This image display processing device reads an original drawing 1 from an image reading section 2.
When the image data is read by the processing unit 7, stored in the storage unit 4 by the processing unit 7, and processed such as correction of the image data, the processing unit 3 is read from the operation unit 6.
The user issues an instruction to display the range that can be displayed on the display unit 5, moves the displayed image data vertically and horizontally using the operation unit 6, detects the necessary portion, and performs processing such as correction.

[Problem to be solved by the invention]

The conventional image display processing device described above performs processing such as correction in order to move the image data displayed on the screen downward, left, and right when detecting a necessary part of the image. If there are many locations, the disadvantage is that the detection work takes time and becomes difficult to operate.

SUMMARY OF THE INVENTION An object of the present invention is to provide an image display processing device that solves the above-mentioned drawbacks and enables smooth and easy display of any part of an image on a display device and processing such as correction of the image. There is something to do.

[Means to solve the problem]

The image display processing device of the present invention includes: an image reading section that reads an image and inputs it as image data; a display section; a storage section; .

an operation section for instructing processing of enlargement and reduction tongues, a position information input section for instructing the position of the image to be displayed on the display section, and a storage section for storing the image image input manually by the image reading section; It has a processing section that reads out the image image from the storage section and displays the image on the display section based on instructions from the operation section and the position information input section.

[Effect]

If you specify the position of the corrected part of the image (for example, its center point) from the position information input section, the processing section will calculate the range that can be displayed on the display section around the specified position and display it on the display section. It is possible to easily select and instruct a portion to be corrected, and processes such as image correction can be performed easily and smoothly.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the image display processing device of the present invention, and FIG. 2 is an image display area diagram illustrating its functions.

The image display processing device of this embodiment includes an image reading section 2 that reads an image and inputs it as image data, a display section 5, a storage section 4, and a correction and enlargement of the image displayed on the display section 5. , an operation section 6 for instructing processing such as reduction, a position information input section 7 for instructing the position of the image to be displayed on the display section 5, and a storage section 4 for storing image data input by the image reading section 2. memorize it,
It is comprised of a processing section 3 that extracts image data from a storage section 4 and displays the image on a display section 5 based on instructions from an operation section 6 and a position information input section 7.

Next, the operation of this embodiment will be explained.

The original drawing 1 is read by the image reading section 2 and stored in the storage section 4 by the processing section 3. When performing processing such as partial correction on the stored image data, first place the original drawing 1 on the position information human power section 7, specify the starting point A of the original drawing 1 and the diagonal end point B, and then The size is manually input to the processing section 3. Next, specify the center point P of the corrected portion. As a result, the display range of the display unit 5 is 640 dots horizontally as shown in FIG. 2, for example.
~ In the case of 400 dots vertically, if the specified center point position is 500 horizontally and vertically, the processing unit 3 calculates the range from 180 to 8200 in the horizontal direction and 300 to 700 in the vertical direction, and processes the image data in that range. The data is taken out from the storage section 4 according to an instruction from the section 3 and displayed on the display section 5. The processing unit 3 calculates and displays a size that fits within the display range centering on the designated position.

In this way, the necessary part can be displayed by specifying it from the position information manual section 7, so that any part can be selected and specified more easily than the conventional method of detecting image data by moving it vertically and horizontally on the screen.

Thereby, the corrected portion can be displayed and processing such as image correction can be easily performed using the operation unit 6.

(Effects of the Invention) As described above, the present invention has a position information input section that instructs the position of the image to be displayed on the display section, thereby smoothly and easily displaying a high-density image on the display section. This has the effect of easily displaying the modified parts when performing corrections or the like.
