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

Claim 13:
14. The image processing method according to claim 13, further comprising:
a luminance information storage step of storing the luminance information for each of the image regions calculated in the luminance information calculation step;
a past luminance determination step of determining a luminance tendency indicating a high or low of luminance of past luminance for each of the image regions from the luminance information for each of the image regions stored in the luminance information storage step; and
a current luminance determination step of determining a current luminance tendency for each of the image regions from current luminance information for each of the image regions calculated in the luminance information calculation step,
wherein the luminance change step comprises executing the luminance change of the corresponding image region on a basis of a change of the luminance tendency determined in the past luminance determination step and the luminance tendency determined in the current luminance determination step in the same image region.
