Abstract:
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, wherein a data block, containing same continuous pixel data, is compressed as one unit of compression, the integral body of information being arranged on a data line of finite bit length, the method comprising:specifying the data block of the one compression unit of the integral body of information; andgenerating 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 generating of a compressed unit data block includes:constituting the coding header by a specific number of bits which indicates that the same pixel data continues up to an end of the data line, when the same pixel data in the data block of one unit of compression continues up to the end of the data line, andthe integral body of information includes a specific header comprising information of a size of the integral body of information.
