Abstract

PURPOSE:To select the desired areas of each picture information after comparing them with each other by reading the picture information on the desired area out of many pictures and arraying them on a display screen. CONSTITUTION:Many pieces of picture information stored in an optical disk memory 1 are decoded by a decoder 3 and read out. At the same time, a window processing circuit 5 compares the address of a desired partial picture of the picture designated previously with the picture address information given from a picture address counter 7. Then only the desired partial picture is sampled and undergoes window processing. This processed partial picture 21 is enlarged or reduced by an enlarging/reducing circuit 9 into a prescribed size. Such controlled partial pictures are stored in a display memory 11 under the control of a write address counter 13. These stored partial pictures are read out successively under the control of a read address counter 15 and arrayed on a display screen.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an image information search and display device that can easily search and display desired image information from a large amount of image information.

[Technical Background of the Invention and Problems Therewith] A large amount of image information such as design drawings is stored and filed on, for example, an optical disk, and desired image information is searched and appropriated from among this file image information. Reliable and rapid retrieval is important for effective and efficient use of image information.

Conventionally, as a method of searching for desired image information from a large amount of image information, a heading is attached to each image information so that it can be identified from the title, content, etc. of each image information, and the desired image information is searched from the heading. Or, there is a method of classifying each image information and searching for each category, or displaying about 10 types of image information as it is on one display device.
There are methods such as displaying them simultaneously on the screen and selecting them. In the former method of searching by heading or searching by category, it is necessary to attach a heading and classify each image information at the time of file, but it is not possible to add a heading or classify it in this way to identify the content. There is a problem in that it is relatively complicated, and it is difficult to add headings or classifying the contents accurately, and it is difficult to accurately search for desired image information using headings or classifications. In addition, the latter method of displaying and selecting about 10 types of images on one screen displays the entire image information as is on one screen, and each image is reduced to a small size. There is a problem in that image information is small and has a lot of useless parts, making it impossible to accurately grasp the content and making it impossible to search efficiently.

[Object of the Invention] This invention has been made in view of the above, and its purpose is to appropriately and efficiently search for, retrieve, and display desired image information from a large amount of image information. An object of the present invention is to provide an image information retrieval and display device for obtaining image information.

[Summary of the Invention] In order to achieve the above object, the present invention reads image information of required predetermined portions from among a large number of images,
The configuration is such that they are displayed side by side on the display screen.

[Embodiments of the invention] Hereinafter, the present invention will be explained in detail using the drawings.

FIG. 1 is a block diagram of an image information search and display device according to an embodiment of the present invention. The image information search and display device shown in the figure constitutes a portion related to image information search and display in, for example, an optical disk image file device.

In the figure, reference numeral 1 denotes an optical disk memory constituting the storage means of the present invention, and a large amount of image information is encoded and stored in this optical disk memory 1. 3 is a decoder that decodes and reads out the image information encoded and stored in the optical disk memory 1; 5 is a window processing circuit, which extracts only the image information of the necessary part of the screen stored in the optical disk memory 1 and designated to be read out. This is a circuit (abbreviated as window processing). Reference numeral 7 designates an image address counter, which indicates the address from end to end of the screen stored in the optical disk memory 1 and designated to be read out, that is, 1 as shown in FIG. 3(a).
This is an image address counter that specifies an address for sequentially scanning from the upper left edge S to the lower right edge E of the screen when scanning the screen 19 in the horizontal direction. In addition, Fig. 3 (a
), a portion 21 shown in the screen 19 shows an image extracted by window processing, and this partial image 21 subjected to window processing is located at the upper left corner S'
is the start address, and the lower right corner E- is the end address. The window processing circuit 5 uses the start address of the upper left end S' and the lower right I of the partial image 21 to be window processed.
The end address of E- is held, and a built-in comparator compares the start address and end address with the address information of the image address counter 7 to extract the image 21 of the part to be subjected to window processing.

Note that the decoder 3, window processing circuit 5, and image address counter 7 constitute the reading means of the present invention.

9 is an enlargement/reduction circuit constituting the image adjustment means of the present invention, and is a circuit for enlarging or reducing the partial image 21 read out after window processing by the window processing circuit 5 to a predetermined size as described above. . For example, as shown in FIG. 2(b), a partial image 21 subjected to window processing from the screen 19 is converted into a partial image 21 by the enlarging/reducing circuit 9 as shown in FIG. 2(C').
The partial image 21' is reduced to a slightly smaller size as shown at 21-, and this reduced partial image 21' is displayed side by side with other images on a display screen 25 of a display device to be described later, as shown in FIG. 2(d). That is, the image adjustment process by the enlargement/reduction circuit 9 is for adjusting the window-processed partial image 21 to a predetermined size that is convenient for displaying the partial image 21 on the display screen 25 side by side with other images. The partial image 21 adjusted to a predetermined size by the enlarging/reducing circuit 9 is stored in the next stage display memory 11 under the control of the write address counter 13. In this case, the partial image 21 is written under the control of the write address counter 13 from the area 27 to be displayed on the display screen 25, that is, from the start address WS at the upper left corner, as shown in FIG. 3(b''). The partial image information is stored in the storage area of the display memory 11 corresponding to the area 27 specified by the end address WE at the lower right corner.The partial image information stored in this way is read out under the control of the read address counter 15. That is, on the display screen 25 of FIG. 3(b), the data is sequentially read from the start address R8 at the upper left end to the end address RE at the lower right end on the display screen of the CR7 display device 17 constituting the display means of the present invention. The display memory 11, write address counter 13, and read address counter 15 constitute display control means.

Next, the operation of the image information search and display device of FIG. 1 constructed as described above will be explained.

A large amount of image information stored in the optical disk memory 1 is decoded and read out by the decoder 3, and at this time, the window processing circuit 5 outputs images of predetermined partial images specified in advance for each image. The address is compared with the image address information from the image address counter 7, and only the necessary partial images are taken out and window-processed, such as the partial image 21 shown in FIG. 2(b), for example. This window-processed partial image 21 is converted into a partial image 21' shown in FIG. 2(C) by the enlarging/reducing circuit 9.
The display memory 1 is reduced to a predetermined size as shown in FIG.
It is accumulated to 1. The partial images 21' stored in the display memory 11 are sequentially read out under the control of the read address counter 15 and displayed on the display screen 2 of the CR7 display device 17.
5, for example, as shown in FIG. 2(d). That is, from each piece of image information stored in the optical disk memory 1 in this way, only the required predetermined partial images are subjected to window processing, and further enlarged/reduced to be adjusted to a predetermined size and displayed on the CR7 display device 17. By displaying multiple pieces of i! image information side by side on the screen 25, a large amount of image information is required. ! 1 itl! It is possible to simultaneously compare and search only the image information I, and it is possible to easily designate, select, and retrieve only the desired image information. In particular, with this image information search and display device, it is possible to enlarge and display only the necessary portion of the image through window processing and enlargement/reduction processing, making it possible to clearly judge the content of the displayed image information. , it is possible to search for desired image information appropriately and quickly.

In the above embodiment, the display memory 11 for only one screen is provided on the display screen 25 of the CR7 display device 17 as shown in FIG. 2(d). As shown in the figure, image information for one screen or more is stored in the display memory 11, and several partial images are simultaneously displayed on the display screen 25, which are smoothly scrolled in the direction shown by the arrow for one screen or more. A large number of images may be displayed sequentially.

Furthermore, this image information search and display device can be used not only in image file devices but also in workstations and many other devices.
