Abstract
A method and circuit are provided for color space conversion of Y (luminance) and UV (chrominance) components from a planar YUV 4:2:0 format to an interleaved, or packed YUV 4:2:2 format, and from an interleaved, or packed YUV 4:2:2 format to a planar YUV 4:2:0 format. The method for both conversions includes reading source data, interpolating the sampled YUV component values, and performing a pass to thereby write the converted YUV component values in three passes, one pass for all values of the respective YUV components.
