Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a system for storing image information and providing it in response to a request from a terminal.

Image information has conventionally been stored by methods such as recording it on photographic film or the like, or recording it as an electrical signal on a magnetic disk device, magnetic tape device, or the like. However, the former method of recording on photographic film has the disadvantage that it is impossible to write information and that it takes time to read out information due to operations such as optical positioning.

On the other hand, in a system in which image information stored in a magnetic disk device or the like is managed by a computer, the information can be accessed randomly and can be easily rewritten. With such a system, it is possible to search for image information and receive desired information from a terminal device having an image memory and a display device. However, in this type of conventional system, each screen to be provided was stored in a magnetic disk device or the like, so it was necessary to store all the screens to be provided. This method has the disadvantage that the amount of data to be stored increases in proportion to the number of screens to be provided.

The present invention stores image information consisting of characters, figures, natural images, etc. separately according to the type of information, manages this using a sub-screen configuration table, and also creates a screen configuration table that defines calculation control for the sub-screens. This is stored and transmitted to the image calculation control device through the transmission path, and this device performs calculation control of the image information according to the definition of the screen configuration table to configure the screen to be provided, and sends it to the terminal device. Its purpose is to avoid increasing the amount of information that must be stored,
The purpose is to provide a variety of image information.

FIG. 1 is a conceptual diagram showing a method of storing image information according to the present invention, in which 100 is a table showing associations between screen information, and 200 is a conceptual diagram showing data stored in a magnetic disk device or the like. The figure shows that the provided screen is constructed by computationally synthesizing sub-screens that are composed of text, graphics, or natural image data. Reference numeral 101 is a screen configuration table, which includes a screen number for screen identification, management information for updating and protecting information, a sub-screen number table, and information for controlling calculations between sub-screens. 102 and 103 are sub-screen configuration tables, which are composed of sub-screen numbers, management information for updating and protecting information, and address information such as character data records, graphic data records, and natural image data records in the magnetic disk device. . The above-mentioned screen configuration table and sub-screen configuration table are stored in a storage device or a magnetic disk device in a control device such as an electronic computer. In order to save storage capacity, the data recorded in the magnetic disk device 200 is, for example, a character code for character data, and a command figure (for example, a command representing a straight line or an arc) for graphic data.
It is assumed that the natural image data is expressed by images encoded using various methods.

Send to 2. The image information conversion device 2 performs calculations between sub-screens according to the calculation control information in the screen configuration table, converts it into pattern information, writes it into the buffer memory device, and sends the information to the terminal 3.

FIG. 3 is an example of the configuration of the image information conversion device in the image information providing system of FIG. 2, and only shows the configuration for synthesizing screen information according to the calculation control information shown in the screen configuration table. . In the figure, 10 is an information identification unit that identifies calculation control information, characters, figures, natural image data, etc. transmitted through the communication line 4, and 11 receives calculation control information and controls each part of the device based on this. 12 is a character pattern generation unit that converts character code information into pattern information; 13 is a graphic generation unit that decodes command graphic information and converts it into pattern information; 14 is a natural image decoding unit; 15 is a 16 is a buffer memory, and 17 is a memory read control section.

The signals are discriminated by the following and sent to the character pattern generation section 12, figure generation section 13, and natural image decoding section 14, respectively.
These devices are controlled based on the arithmetic control information decoded by the arithmetic control section 11 and the sub-screen number.
For example, the size of the figure is determined by controlling the straight line and curve generators in the figure generator 13. The image information generated as described above is written into the buffer memory 16 through the memory write control section 15. After all the screen information has been written to the buffer memory device, the information in the buffer memory 16 is read out by the memory read control section 17 and sent to the terminal 3 through the communication line 5 to be displayed on the image display section.

The arithmetic control section in FIG. 3 decodes the arithmetic control information defined in the screen configuration table shown in FIG. 1 and controls each element of the image information conversion device 2.

It is also possible to take a method of combining various information when configuring a sub-screen by including this information, sending it to an image information conversion device, and interpreting it.

As explained above, in the method of providing image information, a screen is defined as a set including calculations of sub-screens, and the screen to be provided is configured based on this. Even if the amount of image data obtained is not so large, various types of calculation control information in the screen configuration table can be selected, so that a variety of image information can be provided.
