Abstract
A method for processing data for use with a video display includes compressing image data of one or more color planes on a line-by-line basis using lossy compression, wherein at least one lossy compression scheme of a plurality of lossy compression schemes is designated for each line of the plurality of lines to form compressed image data on the line-by-line basis.
Claims20
A method for processing data for use with a video display, comprising:
- compressing image data of one or more color planes on a line-by-line basis using lossy compression, wherein at least one lossy compression scheme of a plurality of lossy compression schemes is designated for each line of a plurality of lines to form compressed image data on said line-by-line basis.
A method for processing data for use with a video display, comprising:
- retrieving compressed image data from a memory;
- and
- decompressing said compressed image data on a line-by-line basis based on each designated compression scheme of a plurality of potential lossy compression schemes for each line of a plurality of lines to form decompressed image data.
A method for processing data for use with a video display, comprising:
- converting RGB color space input image data representing a plurality of lines of data to YCbCr color space image data;
- compressing said YCbCr color space image data of each color plane of said YCbCr color space on a line-by-line basis using lossy compression, wherein at least one lossy compression scheme of a plurality of lossy compression schemes is designated for each line of said plurality of lines to form compressed YCbCr color space image data on said line-by-line basis;
- storing said compressed YCbCr color space image data in a memory;
- retrieving said compressed YCbCr color space image data from said memory;
- decompressing said compressed YCbCr color space image data on said line-by-line basis based on each designated compression scheme for each line to form decompressed YCbCr color space image data;
- and
- converting said decompressed YCbCr color space image data to RGB color space output image data.
