Abstract

PURPOSE:To process a picture retrieval at a high speed by providing a retrieval information memory circuit and writing retrieval information in the retrieval information memory circuit when picture information is written in a picture information memory circuit. CONSTITUTION:When picture data and picture's retrieval identification number, which are displayed on a plotting/retrieving control circuit 2, are handed from a program control part 1, said circuit 2 writes pictures with respect to a display picture memory circuit 3, and further writes the identification number for retrieving the picture at an address corresponding to the position where the picture exists with respect to the retrieval information memory circuit 5. When the program control part 1 receives a retrieval indication from the outside, said circuit 5 reads the retrieval identification number out of the corresponding address according to retrieval position information given separately from the outside, whereby the retrieved result can be immediately obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a CRT display device, and more particularly to a display image search method in a CRT display device.

BACKGROUND OF THE INVENTION Conventionally, a CRT display device having this type of search function has a circuit configuration shown in 2g:J, in which image information to be searched for is searched by a drawing/search control circuit 2 during a line search. , processing was executed until the desired image information was found.

The problem that the invention seeks to solve However, the above-mentioned search method is not effective at the time of search.

Since the search process is performed for each piece of image information, there is a drawback that the search response speed becomes extremely slow when there are many displayed images and the selected image is the last one to be searched.

The present invention has been made in order to eliminate the above-mentioned drawbacks inherent in the conventional technology, and therefore, an object of the present invention is to provide a novel CR that makes it possible to perform image search processing at high speed.
An object of the present invention is to provide a T display device.

Means for Solving the Problems In order to achieve the above object, C) the LT display device according to the present invention has an image display device that stores image information to be displayed. 1 information storage means, means for storing search information of images to be imposed, means for inputting search information of the image into the search information storage means when writing the image to the image ad storage means, and a means for storing search information of the image to be imposed; The information storage means and the search information ttm+ output means are comprised.

Embodiment Next, a preferred embodiment of the present invention will be specifically explained with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.

In Figure 1, when the image data to be displayed and the search identification number of the image are passed from the program control unit l to the drawing/search control circuit 2, the drawing/search control circuit 2 sends the image data to the display image storage circuit 3. At the same time, an image is written into the search information storage circuit 5, and an image search identification number is written into the address corresponding to the location of the image.

Here, the search information storage circuit 5 is configured to be able to store one or more search identification numbers for each pixel on the display screen. When the program control unit 1 receives a search instruction from the outside, it reads out a search identification number from the address corresponding to the search position in the search information storage circuit 5 based on search position information separately given from the outside. In this way, search results can be obtained instantly.

As described in detail, the present invention includes a search information storage circuit having a configuration corresponding to a display screen, and when writing image information to the image information storage circuit, the search information is stored in the search information storage circuit. By writing in the image data, it is possible to achieve the effect of speeding up processing during image retrieval.
