When various reverse operations are performed using a scan reverse function that reverses an image vertically or horizontally, there is a problem in that color information of the first pixel of an image after being reversed is different from color information of the first pixel of a Bayer image before interpolation processing. An image processing apparatus performs interpolation processing on a first image of a Bayer pattern, generates a second image in which colors are arranged in an order reverse to the predetermined order from an interpolated image, and stores the second image in a memory. The image processing apparatus reverses the second image when reading the second image from the memory.
