Assignee: ROLAND CORPORATION
Field: Audio-visual technology (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 2:
3. The image processing device according to claim 1, further comprising:
a change coefficient calculation part configured to calculate a luminance change coefficient used for the luminance change of the luminance change part from the luminance info illation for each of the image regions calculated by the luminance information calculation part,
wherein the luminance information storage part stores the luminance change coefficient used for the luminance change of the luminance change part together with the luminance information for each of the image regions, and
in a case when the luminance tendency determined by the past luminance determination part and the luminance tendency determined by the current luminance determination part are the same in the same image region, the luminance change part executes the luminance change of the corresponding image region using the luminance change coefficient according to an intermediate value between the past luminance change coefficient of the corresponding image region stored in the luminance information storage part and the current luminance change coefficient of the corresponding image region calculated by the change coefficient calculation part.
