Compression by chrominance subsampling in color image acquisition

摘要

A method and apparatus for compressing a color image by reducing the amount of color information initially acquired. The color information can later be restored by interpolation from other portions of the image where the color information is available. This not only reduces the amount of data that needs to be stored, but improves the scanning time for an image scanner by reducing the amount of time needed to scan the image. In a preferred embodiment, both the scanning time and the amount of data can be cut in half.
