Abstract:
An image processing apparatus configured to process pixels having missing image signals by interpolation, said pixels being arranged in a grid configuration wherein each pixel is between other pixels in a horizontal direction and a vertical direction, said other pixels having image signals corresponding to said missing image signals, said apparatus comprising:an interpolating unit configured to generate interpolation signals of a pixel to be interpolated according to each degree of changes in image signals of four adjacent pixels located at positions surrounding said pixel to be interpolated, and according to each degree of changes in image signals of said pixel to be interpolated, wherein: each degree of changes is determined by determining a difference between at least two pixels adjacent to the pixel for which the degree of change is determined, and said each degree of changes in image signals of the four adjacent pixels is determined by determining a difference between at least two pixels of the same color as the adjacent pixel for which the degree of change is determined.
