Abstract
A color image () is compressed by associating a variable length color code with each color of the original colour image, and then forming bitplanes (-) each representing one bit position of the binary color codes for each pixel of the color image. The variable length codes are optimized, such as by a canonical Huffman algorithm. Compression is high, even for simple icons and special character images (e.g. 16×16 pixels). Decompression is simple, fast and resource inexpensive. Amongst many other uses, the image decompression is suitable for use in a cellular telephone having a color LCD display.
