Abstract:
1. A method for processing image data in a liquid crystal display (LCD) overdrive system, said method comprising: receiving original image data for display on an LCD display; sending said original image data to an overdrive calculation module for calculation of overdrive image data; sending said overdrive image data to a prediction module for calculation of predicted image data; reducing a bit depth of said predicted image data using a non-linear mapping function thereby creating reduced image data; converting said reduced image data from a luminance-integrated color space to a luminance-segregated color space comprising a luminance channel and at least one chrominance channel; spatially down-sampling said at least one chrominance channel; and compressing said reduced, converted and down-sampled image using spatial redundancy methods, thereby creating compressed image data; storing said compressed image data in a buffer; decompressing said compressed image data after a delay, thereby creating decompressed, delayed image data; and using said decompressed, delayed image data for overdrive-related calculations for a subsequent image frame.
