Abstract

A color interpolation method with directed weights is disclosed, which provides an algorithm for interpolating pixels into raw data, the method comprising: extracting raw data; generating a digital image of a color filter array; then calculating a weight of a neighbor pixel of a raw pixel, calculating its bilinear interpolation value, and calculating a first set of pixel differential values between a plurality of neighbor pixels and the bilinear interpolation value; and then obtaining a first interpolation pixel and a second interpolation pixel interpolated into the raw pixel, wherein the pixels are interpolated according to each directed weight of the raw pixel, or interpolated according to the weights after determining each directed weights of a color differential value domain applied in the raw pixel; thereby inferring the interpolation pixels of each raw pixel, so as to reduce an edge blur effect generated during a color image recovery.
