摘要

A high frequency component detector detects a high frequency component of an R signal. A high frequency component comparator outputs a flag indicating a threshold value division range having the highest threshold value including a value of a high frequency component in a specific period. A gain calculating unit calculates a ratio as a gain, the ratio set according to the threshold value division range indicated by the flag input. A multiplying unit multiplies the R signal and the gain to generate an object signal R′wherein a concavity and convexity difference with adjacent pixels in a small region of an image is suppressed compared to the R signal.
