Abstract
A method and apparatus for compressing and decompressing small amounts of image data, such as icon image data, is disclosed. The image data is transformed from RGB color space data to luminance and chrominance data. The chrominance data is then reduced by means of a thinning or averaging process. Run length encoding is performed on the luminance data and reduced chrominance data to compress for storage. The invention allows accurate and efficient storage and use of a small amount of compressed image data, particularly for continuous tone icons.
