There is disclosed an image processing method wherein there is read, from a memory, an image signal which contains a plurality of image components and in which a sampling ratio as a ratio of sampling frequencies of these image components is not matched. The sampling ratio of the read image signal is converted to match the sampling ratio of the image signal. The image signal whose sampling ratio has been converted is filtered. The sampling ratio of the filtered image signal is converted to reduce a data size of the signal.
