FIELD: information technology.
SUBSTANCE: image processing device stores in memory first image data having the highest frequency among a plurality of image data fragments of different frequency ranges in a state in which each pixel of the first image data includes a colour component signal of any of a plurality of colours, and further stores in memory second image data and third image data whose frequency ranges are lower than that of the first image data, in a state in which some or all pixels of the second and third image data have colour component signals of a plurality of colours.
EFFECT: image processing device can perform corresponding image processing, while simultaneously preventing increase in memory capacity for storing a plurality of image data fragments of different frequency ranges.
