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

Claim 14:
15. The image processing method according to claim 14,
wherein the luminance information storage step comprises storing a luminance change coefficient together with the luminance information for each of the image regions, the luminance change coefficient being a coefficient used for the luminance change in the luminance change step; and
a standard coefficient acquisition step of acquiring a standard coefficient, the standard coefficient being the luminance change coefficient in a case in which the luminance change is performed on the image region in which a luminance tendency is medium luminance, 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 standard coefficient acquired in the standard coefficient acquisition 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.
