摘要： An image processing apparatus can execute appropriate image processing while preventing increase in a capacity of a memory for storing a plurality of pieces of image data of different frequency bands. The image processing apparatus stores first image data having the highest frequency among the plurality of pieces of image data of different frequency bands in a state in which each pixel of the first image data includes a color component signal of any of a plurality of colors, on the memory, and further stores second image data and third image data whose frequency bands are lower than that of the first image data on the memory, in a state in which a part of or all pixels of the second and the third image data have color component signals of a plurality of colors.
