Abstract
A method and apparatus for pixel interpolation performed on color separated image data which is obtained from a Bayer array or like sensor. The slopes of pixel values are computed in two or more directions and pixel weight factors are calculated corresponding to these directions based on the computed slopes. The pixel weight factors are used in the pixel interpolation calculation to improve the interpolated result such as is necessary in the edge region of an image.
