Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field of the Invention) The present invention relates to an image abstract control method, in particular, a method for extracting a desired portion of image data and thinning it, and transmitting or displaying the data. This invention relates to an image abstract control method that aims to reduce the time required for display, etc.

(Technical background and problems) Figures, symbols, characters, etc. written on a manuscript are converted into electrical signals using a scanner and developed into image data, which is then displayed on a display to confirm the content and arrangement of the manuscript. Or proofreading the printed manuscript (galley). When confirming the contents, arrangement, etc. of the document, it is desired that the contents of desired image data be quickly transferred and displayed on a display.

However, since image data is a dot-shaped representation of the figures written in the manuscript,
The amount of data is large, and the amount of data increases as high image quality is maintained, such as in a printed manuscript. For this reason, conventionally, when proofreading a printed document on a display, it takes a lot of time to transfer or display the desired image data, and sometimes the image data is not displayed on the display. There were times when I had to give up on things.

(Object and Structure of the Invention) An object of the present invention is to solve the above-mentioned problems, and to extract abstract information or extract/thin out processing for extracting a desired portion of image data and performing thinning processing. For example, by storing the data together with the image data,
The purpose is to quickly transfer desired image data as needed and display it on a display. Therefore, the image abstract control method of the present invention is an image abstract control method that converts figures and symbols described in a manuscript into the form of electrical signals and displays an abstracted image on a display. An image conversion mechanism that converts figures and symbols into electrical signals and develops them in the form of dots in an image memory, and an image that displays the images developed in the image memory by the image conversion mechanism on a display. A display mechanism and instructions for inputting abstract information necessary for instructing the desired position and size of the image displayed on the display by the image display mechanism and generating an abstract of the area corresponding to the instruction. an abstract information storage section that temporarily stores the abstract information input by the input instruction section; a file section that stores the image data stored in the image memory; a search mechanism for searching the desired stored image data; and image data corresponding to the abstract that is reduced at a predetermined thinning rate with respect to the area corresponding to the instruction based on the abstract information and image data. an image abstract extraction mechanism for extracting the image abstract extraction mechanism, the image data extracted by the image abstract extraction mechanism and the image data retrieved from the file section are held in correspondence, and The present invention is characterized in that either one of the two images is arbitrarily switched to the image memory, developed, and displayed on the display.

The figure shows an instruction for image abstraction, and shows a state in which a so-called abstract area, etc., in which important parts are to be extracted and displayed from the image data displayed on the image display 4 is specified. As an instruction for the abstract, first, the name of the image manuscript, which is a search key, is input. Second, to specify the rectangular abstract area shown in the figure a, coordinates P (X1, Y1) and Q (X2, Y2) from the origin (upper left in the figure) are used.
Enter . By inputting these two coordinates, the main part of the original image document that becomes the abstract is specified. Third, input the thinning rate, for example, 1/2. By inputting the thinning rate,
Since the rectangular abstract area specified by the coordinates P and Q is reduced to one-half, that is, the area is reduced to one-fourth, the dot

Then, for the manuscript to be printed, etc., a draft for final printing may be created based on the original high-quality image data stored in the file section 8.

In order to generate an image abstract using FIGS. 1 to 3, the abstract information and image data are stored in the file section 8, and the abstracted image is displayed on the image display 4. At the time, we abstracted the original image data. However, the invention is not limited to this, and abstracted image data may be previously stored in the file section 8 together with the original image data. In this case, although the storage area for storing the abstracted image data becomes larger, the abstracted image can be displayed on the image display 4 more quickly.

(Effects of the Invention) As described above, according to the present invention, abstract information for extracting a desired portion of image data and performing thinning processing or data that has been extracted and thinned out is extracted from, for example, the image data. The desired abstracted image can be quickly displayed on the display to check the arrangement, etc., thereby improving efficiency, and when editing the image or final printing, etc. High quality images can be obtained using the original image data.
