Patent ID: 7480417

Claim:
A method for encoding mosaiced image data comprising the process actions of: inputting raw charged couple device (CCD) image data; splitting the raw CCD data into red (R), a first green (G 1 ), a second green (G 2 ) and a blue (B) channel on a macro-pixel basis, wherein each macro-pixel comprises a set of a first green and a second green diagonally adjacent pixels and a red-blue pair of pixels R, B that is diagonally adjacent; transforming the red, first green, second green and blue channels into Y, Dg, Co and Cg color space channels, each representing an image one quarter the size of the original image wherein for each macro-pixel the Y channel represents luminance, Dg represents the difference between the first green pixel and the second green pixel, and the Co and Cg channels are color channels; and separately encoding each of the Y, Dg, Co and Cg channels with an encoder.
