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

Claim 15:
16. The image processing method according to claim 14, further comprising:
a change coefficient calculation step of calculating a luminance change coefficient used for the luminance change in the luminance change step from the luminance information for each of the image regions calculated in the luminance information calculation step,
wherein the luminance information storage step comprises storing the luminance change coefficient used for the luminance change in the luminance change step together with the luminance information for each of the image regions, and
the luminance change step comprises executing 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 step and the current luminance change coefficient of the corresponding image region calculated in the change coefficient calculation step when the luminance tendency determined in the past luminance determination step and the luminance tendency determined in the current luminance determination part in the same image region differ.
