ABSTRACT:
Correlation values in the vertical direction, horizontal direction and two diagonal directions are obtained in a pixel signal of RGB Bayer pattern. The correlation values are calculated using G signals. Between a first pair of the vertical and horizontal directions and a second pair of the two diagonal directions, one pair having a greater correlation difference is selected. Then, a direction having a stronger correlation is selected in the selected pair having a greater correlation difference, and pixel interpolation is performed in the selected direction. Alternatively, pixel interpolation is performed following assignment of weights in two directions of the selected pair having a greater correlation difference in accordance with the proportion of their correlations.
