Abstract
Provided are a graphic image data compressor that provides a complete image instead of an erroneous image when graphic image data fails to be compressed to satisfy its bandwidth and a method of compressing graphic image data using the same, where the graphic image data compressor includes a compression block for compressing received graphic image data using a loss compression algorithm and a lossless compression algorithm and controlling an amount of loss data in the loss and lossless compression algorithms, and a compressed data determination block for comparing a compression rate of data compressed according to the loss and lossless compression algorithms with an established compression rate, selecting optimum compressed data, and determining to output the selected compressed data or the graphic image data.
