Various types of image compression have been proposed. The present invention compresses image data using a predetermined compression technique such as the Microsoft S3 compression scheme. The compressed image is then decompressed and difference values derived between the original image and the decompressed...
Disclosed is a digital image compression and decompression method and apparatus for dividing a supplied digital image signal into blocks of predetermined size, performing variable-length coding of the signal, separating the signal with respect to principle information and remaining information, and controll...

A simple and fast lossy compression and decompression algorithm for digital images is proposed. The method offers varying compression ratios (depending on dimensions of the image) and the acquired decompressed image is close to the original one. A selectable tradeoff between storage size and image qu...
An encoding/compression technique using a combination of predictive coding and run length encoding allows for efficient compression of images produced by error diffusion. The compression process comprises predictively coding (S50-S200) an error diffused image made up of a plurality of error diffused si...
