Abstract
An image processing apparatus includes an interpolation unit, compensation value calculation unit, and compensation unit. For an interpolation point selected from an image signal at an interval of n pixels (n is an integer of 2 or more), the interpolation unit interpolates the pixel value of each color data at the interpolation point using the pixel values of pixels of the same color falling within an interpolation region of m×m pixels (m is an integer of 2 or more) centered on the interpolation point, and outputs the pixel value as an interpolated pixel value at the interpolation point for each color data. The compensation value calculation unit generates a pixel compensation value for compensating for the pixel value of the interpolation point using the pixel values of pixels falling within a compensation region of M×M pixels (M is an integer equal to or larger than m and n) centered on the interpolation point. The compensation unit compensates for the interpolated pixel value of each color data at the interpolation point that is output from the interpolation unit by using the pixel compensation value corresponding to the interpolation point that is obtained by the compensation value calculation unit, and outputs the compensated pixel value as a new pixel value of each color data at the interpolation point.
