Abstract
A color interpolation method capable of more precisely interpolating each of pixels of an image passing through a color filter of a Bayer pattern and detected by an image sensor, the method including: defining a pixel group of a matrix structure, having a pixel to be color-interpolated as a center pixel, in an image passed through a color filter of Bayer pattern and detected by an image sensor; determining whether an edge exists or not in the pixel group; interpolating a color of the center pixel using a low pass filter when an edge does not exist in the pixel group; and interpolating a color of the center pixel according to directivity of an edge when the edge exists in the pixel group. The invention suppresses noise during color interpolation and enables more precise color interpolation.
