Abstract
An image compression apparatus comprising, a dividing section for dividing image data to be compressed into a plurality of blocks, a compression section for compressing in order each block of the plurality of blocks which have been obtained by divided in the dividing section, wherein the compression section converts the continuing blocks of the same image contents, into basic data and continuous compressed data, wherein the basic data is a compressed date from any one of the continuing blocks of the same image contents, and the count data indicates a number of the continuing blocks.
Claims4
An image compression apparatus comprising;
- a dividing section for dividing image data to be compressed into a plurality of blocks;
- a compression section for compressing in order each block of the plurality of blocks which have been obtained by divided in the dividing section;
- wherein the compression section converts the continuing blocks of the same image contents, into basic data and continuous compressed data;
- wherein the basic data is a compressed date from any one of the continuing blocks of the same image contents, and
- the count data indicates a number of the continuing blocks.
An image expansion apparatus expanding compressed data which has been compressed in order each block of a plurality of blocks obtained by dividing image data, and which has been converted into continuous compressed data containing a basic data which is a compressed date from any one of continuing blocks of the same image contents and a count data indicating a number of continuing blocks, and comprising;
- a detection section detecting the continuous compressed data;
- a repeat output section expanding the basic data of the continuous compressed data detected by the detecting section into one block of image data, and repeating output of the one block of the image data the same number of times as the number of the continuing blocks indicated by the count data.
