Abstract
When processing an image of a two-dimensional pixel arrangement such as a Bayer arrangement, when a pixel G (j, i) of a first color component which represents luminance is interpolated, the value of the first color component associated with the primary reference pixels located adjacent to the top and bottom or left and right of the interpolated pixel position, and secondary reference pixels of the first color component, located in the vicinity of the primary reference pixel, is checked. The existence of an image edge component is detected. When an image edge component is detected, the weight of the reference pixels, for example, G(j−1, i), G(j+1, i), G(j, i−1) and G(j, i+1) is changed at the top, bottom, left and right.
