Abstract:
1. In a digital image computing device, a method of pre-processing an image for improved data compression by exposing one or more common patterns in the image data that are typically unrecognizable by a bit stream processor when the image data is displayed in color channel interleaved form, the method comprising: receiving a digital image represented as a plurality of pixels, wherein each pixel is defined by a first color space including at least two color channels that are typically displayed such that the layout of the plurality of pixels appears as an interleaved sequence of the at least two color channels; separating the digital image into a planar data source for each of the at least two color channels by splitting each color component of each pixel into the planar data source for the corresponding color channel; sub-sampling a particular planar data source by: sending the at least two planar data sources to the one or more data compression modules where each planar data source is separately compressed in order to more efficiently compress the digital image than when the digital image is in its interleaved form; and one or more of:
