Abstract

PURPOSE:To retreive and display a detailed picture further with addition of difference information only the storing original pattern information from outline picture information up to detailed picture information in terms of hierarchy to indicate directly an optional area in a display picture. CONSTITUTION:A center processing unit 3 reads the outline picture information from a magnetic disc 5, a terminal processing unit 8 stores it in a terminal memory 9 via interfaces 6, 7 and displays it on a display device 11. The center processing unit 3 reads the difference information of a part corresponding to the area from a center memory 4 by using a command device 12 to indicate an optional area in the outline picture displayed on the display device 11. Then the terminal processing unit 8 extracts the part corresponding to the commanded area out of the outline picture information stored in the terminal memory 9, transmits it to a synthesizer 10 together with the difference information transmitted from the center processing unit 3, synthesizes detailed picture information and displays the detailed picture on the display device 11. That is, after the number of picture elements of the information of one picture element of the outline picture 15 is increased as information 17, it is allowed to correspond to plural difference information 18.

Description

DETAILED DESCRIPTION OF THE INVENTION (1) Field of the Invention The present invention relates to a storage, retrieval and display method for image information, particularly a storage, retrieval and display method for image information handled in a system that retrieves and displays image information stored in a center, etc. Regarding.

(2) Description of Prior Art FIG. 1 shows the structure of screen information to be searched for stored in a center or the like in a conventional method. Conventionally, this type of method is limited by the resolution of the nine display devices, making it difficult to simultaneously display all of the screen information to be searched, such as a wide area such as an aerial photograph (this is referred to as original screen information in Figure 1), on the display device. Since it is impossible to
2. ... and give each small screen information a unique name such as a screen number, and use this as a keyword and the options to search by following the option list 2 as shown in Figure 1. . That is, the divided small screen information is stored in a center or the like as a unit and searched and displayed.

However, when searching for visual information over a wide area, such as an aerial photograph, it is difficult to divide this into small screen information and uniquely represent this with linguistic information such as keywords. The selected small screen information is often not what is desired, and unnecessary re-searches are often performed. Furthermore, since the search and display is carried out using nine divided screens as a unit, it is difficult to confirm the positional relationship between pieces of small screen information that blink together. To achieve this, the amount of information that can be accumulated can be increased by creating overlapping parts between adjacent small screens, or by composing small screen information at an intermediate position from multiple adjacent small screen information each time it is displayed. However, there were disadvantages such as a large increase in the amount of processing required at the center, etc.

(3) Purpose of the Invention In order to solve these drawbacks, the present invention stores original screen information, which is a continuous piece of information, hierarchically from a general image to a detailed image using difference information, and creates nine options. The detailed image is searched step by step by directly specifying an arbitrary area in the general image without using it, and the detailed image can be displayed by combining the difference information with the information of the specified area in the general image. The purpose is to

(4) Explanation of the structure and operation of the invention The present invention will be explained in detail below using examples.

FIG. 2 shows an example of the configuration of an image information search and display system.

In the figure, 3 is a center processing device, 4 is a center memory,
5 is a magnetic disk, 6 and 7 are input/output interfaces, 8
is a terminal processing device, 9 is a terminal memory, 10 is a synthesizer, 11
is a display.

12 is an indicating device. First, the center processing amount bL3 is determined by reading rough image information from the magnetic disk 5, and inputting/outputting ink 7.
The data is transmitted to the display device through the Ace 6 and 7, and the terminal processing device 8 stores it in the terminal memory 9 and displays it on the display 11. Next is the instruction device! ! 12 to specify an arbitrary area within the schematic image displayed on the display 11, the center processing device 5 stores the center memory 4.
The memory reads the difference information of the portion corresponding to the area from the magnetic disk 5 and transmits it to the display device.

The terminal processing amount rr1.8 cuts out a portion corresponding to the designated area from the general image information stored in the terminal memory 9, sends it to the synthesizer 10 together with the difference information sent from the center processing amount W6, and generates a detailed image. Synthesizing information and displaying detailed images on the display 11 FIG. 6 schematically shows an example of the hierarchical structure of image information stored in the center. In general, two or more pixels of the detailed image 14 obtained corresponding to the illustrated original screen information 16 are represented by one pixel to create the schematic image 1-5.
．． 16. , with the most detailed image at level 0, and the more schematic n images (7) [sequentially level 1. Level 2. . . . give levels N (N is a positive integer, N-2 in FIG. 3). Also, level i (i=o,
1. ....

The information on the layer at level N-1 (positive integer) is given as difference information from the information on the layer at level (++1).

Suppress the increase in the amount of stored information due to the hierarchical structure. In FIG. 3, the level 2 schematic image 16 is constructed by representing 4×4 pixels of original screen information as one pixel using their average luminance information and the like. Further, the level 1 schematic image 15 is constructed by representing 2×2 pixels of original screen information as one pixel using their average luminance information. The level 0 detailed image 14 is image information composed of the same number of pixels as the original screen information. As for accumulated image information, at level 1, it is stored in the form of difference information between level 2, that is, the average brightness information of 4 × 4 pixels and average brightness information of 2 × 21111 pixels, and at level 0, it is stored in the form of difference information between level 2, that is, the average brightness information of 2 × 2111 pixels, and at level 0, it is stored in the form of difference information between level 2, that is, the average brightness information of 2 × 21111 pixels. It is stored in the form of difference information between brightness information and original screen information.

FIG. 4 shows a method of synthesizing detailed images in the synthesizer 10. 1 of the schematic images 15 corresponding to the designated area in the figure
By increasing the number of pixels of the pixel information as shown in the information 17 in B in the figure, and making it correspond to a plurality of pieces of difference information 18 (four pieces in the case of the fourth cabinet), and adding these separately, the information shown in the figure can be obtained. Information on a plurality of pixels (four in FIG. 4) is created as shown in FIG.

Note that the numerical values in FIG. 9 mean brightness information of each pixel.

FIG. 5 shows an example of application of the present invention. Since it is impossible to display all information on a display device at the same time with a pixel count of level O, the original screen information is first displayed as an overall schematic image, for example 16, as shown in figure 19, and then as shown in figure 20. The search display is performed by displaying the designated area in the form of an image 15 as shown in FIG. 21, and further displaying the designated area in FIG. 22 as a more detailed image 14 as shown in FIG. 26.

In the above explanation, information indicating a wide area such as an aerial photograph was explained as the original screen information, but the small screen information shown in Figure 1 is a collection of independent information that has no relationship with each other to form information that constitutes a wide area. It is also possible to handle

(5) Description of effects As explained above, according to the present invention, original screen information is stored hierarchically from general image information to detailed image information, and any area within a displayed image can be directly accessed. By giving instructions, more detailed images can be searched and displayed simply by adding difference information. Therefore, the operator can check the continuity of any part of the original screen information with the surroundings, and
Search and display is possible by direct manipulation of visual information. Furthermore, by temporarily storing the general image information in the display device, it is possible to immediately display the general image and search again without retransmitting the image information from the center. Therefore, even if you make a mistake in your search, there is no need to restart your search from the beginning.

You can search again in a short time.
