Image information encoding/decoding system
First Claim
1. A method of encoding an integral body of information which is formed of a plurality of pixel data each defined by a predetermined number of bits, and is arranged on a finite length data line corresponding to a display frame or display field of a TV, wherein a data block, containing same continuous pixel data, is compressed as one unit of compression, the encoding method comprising:
- specifying the data block of the one compression unit of the integral body of information; and
generating a compressed unit data block in accordance with a coding header corresponding to a continuing number of the same pixel data in the data block of the one compression unit, with a number of pixels followed indicating the continuing number of the same pixel data, and with data representing the same pixel data in the data block of the one compression unit, wherein;
the coding header is indicative of a number of following bits representing a data length of the continuing number of the same pixel data,a number of bits in the coding header is indicative of the number of following bits representing the data length of the continuing number of the same pixel data andthe integral body of information includes a specific header comprising information of a size of the integral body of information.

Abstract
A bit train of a plurality of continuous pixels is compressed according to a new run-length compression scheme. In this run-length compression scheme, the run information of one unit of compression includes run-length information indicating the continuous number of the same pixel data blocks, or the number of pixels followed, and pixel data having a two-bit configuration for discriminating three or more colors of the pixels.

3. A method of decoding a bit train of a unit of a compressed data block, which is obtained by compressing same continuous pixel data as one unit of compression, wherein the compressed data block corresponds to at least part of an integral body of information formed by a plurality of pixel data each defined by a predetermined number of bits, wherein the integral body of information is arranged on a finite length data line corresponding to a display frame or a display field of a TV, and wherein the compressed data block includes either a coding header indicating data of a number of pixels followed, which number data corresponds to the number of the same continuous pixel data, or a coding header indicating the number data of pixels followed as well as the same continuous pixel data, the decoding method comprising:
-
detecting the coding header from the data block of the one compression unit contained in the integral body of information; detecting the number data of the pixels followed, from the data block of the one compression unit, in accordance with a content of the coding header detected by the coding header detecting step; determining a content of the pixel data in an uncompressed data block of the one compression unit, in accordance with a remainder of the data block of the one compression unit, from which removed are the coding header detected by the coding header detecting step and the number data of the pixels followed detected by the continuous pixel number detecting step; and arranging bit data of the content determined by the pixel data determining step, by a number indicated by the number data of the pixels followed detected by the continuous pixel number detecting step, so as to restore a pattern of uncompressed pixel data of the one compression unit, wherein the integral body of information includes a specific header comprising information of a size of the integral body of information.
