VIDEO SIGNAL PROCESSING DEVICE AND VIDEO SIGNAL PROCESSING METHOD

WIPO Patent Application WO/2015/174125

A1

Cumulative degree of risk of degradation is calculated for each area by calculating and accumulating the degrees of risk of degradation for each area into which a displayed image is divided from the amount of light emitted by each pixel based on a video signal by a light emission calculation unit (302), a block degree of risk calculation unit (303), a block degree of risk updating unit (304), an area degree of risk calculation unit (305), and an area degree of risk updating unit (306). A gain calculation unit (307) calculates the degree of risk of degradation for each pixel from the cumulative degree of risk of degradation that has been calculated for each area and calculates correction gain for each pixel on the basis of the degree of risk of degradation for each pixel and brightness for each pixel. A multiplier (390) corrects the signal level of the video signal using a correction gain calculated by the gain calculation unit (307). The signal level for the video signal is adjusted such that the brightness for areas for which the degree of risk of degradation is high is lower than that for areas for which the degree of risk of degradation is low. Thus, increased life for light emitting elements and high visibility of the display can be achieved.
