ABSTRACT:
A color signal interpolation system and method, which performs a green sample interpolation on a signal with a cross color sample. The method includes: (A) providing neighboring color samples on an interpolation sample; (B) computing a luminance respectively of the interpolation sample and the neighboring color samples; (C) computing an edge value of the interpolation sample based on the luminance computed; (D) determining if the edge value is smaller than a predetermined threshold; (E) computing an average of the neighboring color samples that have the same color with the interpolation sample when the edge value is smaller than the predetermined threshold, and using the average as a first color output of the interpolation sample.
