Abstract

PURPOSE:To obtain extendability and flexibility that allow easy absorption of addition and alteration of CCT format by performing hierarchical control of various format specifications by logical format editor mechanism. CONSTITUTION:The logical format editor mechanism 6 defines and registers CCT format that becomes an object of processing in a picture processing system from outside. A CCT input/output processor 10 performs processing basing on a specification prescribing file group prepared by the ligical format editor mechanism 6. It extracts picture data characteristic of CCT that becomes an object of processing, determines number of volumes, retrieves pointer of a file specification table that becomes an object of processing, and performs analysis of relevant file specification table basing on the pointer, and rationality check of file arrangement according to file specification.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to an image processing system, and in particular to a CCT input/output control device suitable for various types of OCT input processing for image analysis and CCT format conversion processing. Measure.

[Prior art]

OCT input/output processing in conventional image processing systems is
In response to newly launched satellites and sensors,
Software was developed each time the OCT format was different, and the software was modified individually for additions and changes to the OCT format.

For this reason, (1) OCT input/output processing is likely to depend on the CCT format.

(2) A huge amount of time and effort is spent on developing CCT input/output processing.

(3) Poor expandability and flexibility.

(4) The maintainability of the program is low.

There were drawbacks such as.

[Purpose of the invention]

The purpose of the present invention is to easily register the format specifications of various OCT formats using a PIF format definition means, standardize the process of generating CCT input/output processing procedures to be processed, and to standardize the process that is relatively troublesome in the past. It had been,
An object of the present invention is to provide an OCT input/output control device having expandability and flexibility that easily absorbs additions and changes to CCT formats.

[Summary of the invention]

The key point of the present invention is that each satellite and sensor has a different CCT.
In order to absorb the physical structure of the format, it uses a logical format nibbutter mechanism to perform hierarchical management of various format specifications, and incorporates both the functions of an OCT input/output processor that analyzes and processes management information. be.

Figure 1 is a system configuration diagram, where D, 1.2 is a magnetic tape device necessary for OCT input/output, 3 is a large-capacity disk device that stores image data input from OCT, and 4 is OCT.
Control electronic computer with built-in input/output control device, 5 is OC
Character for registering T format from outside
It is a display device.

FIG. 2 shows details of the CCT input/output control device that is the object of the present invention.

The OCT format to be processed by the image processing system is defined and registered from the outside. Tsumashi, CCT in 7
In order to absorb the physical structure that differs for each format (uncorrected for black and white, corrected for black and white, uncorrected for color, corrected for color), such as format volume management and image data management between volumes, Following the definition procedure according to the format, first, the basic definition of the record specifications (input/output buffer location, conversion characteristics, etc.), which is the minimum data set that makes up the OCT, is performed, and then the organic structure of each file is defined based on the record specifications. Various definitions of volume definitions (image characteristics, logical volume information, etc.) are performed based on the file definition that defines a set of records and the file fixed trajectory, and the file definitions are registered in the character display 5 and the specification specification file group 9 is created. (The volume specification file, file specification file, and record specification file are all connected by logical pointers).

Next, the OCT input/output processor 10 extracts the OCT image data characteristics to be processed, determines the number of volumes, and extracts the OCT image data characteristics to be processed in step 11 based on the specification file group created by the logical format nibbutter mechanism. and the pointer of the file specification tool 7' to be processed, and
At step 18, the relevant file specification table is analyzed based on the pointer, and the rationality of the file arrangement according to the file specifications is checked.If an abnormal format is detected, an alarm message is output at step 18, and the process ends.

In addition, during normal operation, the pointer of the record specification table to be processed that belongs to the file is indexed, and in step 14, the corresponding code specification table is analyzed based on the pointer, and the input/output buffer address is determined. After extracting record specifications such as input/output conversion characteristics, data consistency is checked in step 15, and if an abnormality occurs, an alarm message is output in step 18, and the process is terminated. Under normal conditions, O based on the record specifications.
CT input processing 16 and CC7 format conversion processing 17
Wait a few minutes for the applicable code, applicable file, and applicable volume. In this way, the physical CCT
To enable logical OCT input/output processing for analyzing specification files without being aware of formats.

Note that 8 in the figure is a PIF sheet, and 13 is a format check mechanism.

〔Effect of the invention〕

According to the present invention, development of a program (CCT input/output processing) compatible with a new satellite and sensor can reduce software man-hours and greatly shorten the development period as input/output processing is standardized. Also, logical format data
With the enhancement of the mechanism, addition of CCT format
Changes can be made by simply adding or changing a group of specification files, resulting in excellent expandability and flexibility.
