摘要
A method is provided for reducing occurrence of color fringe errors occurred at the time of carrying out a color filter interpolation and reducing degradation of an image quality. Interpolation of a G channel value in a pixel of the color filter having only R or B channel values is carried out such that a similarity measured between channels based on interpolation results in horizontal and vertical directions are measured, and the G channel interpolation is carried out in a direction where the measured similarity becomes the maximized. However, when the reliability of the measured similarity becomes poor, a final G channel interpolation is carried out using a weighted average value using similarity information of each direction and interpolation results of the horizontal and vertical directions.
