METHOD FOR GENERATING TARGET GAIN VALUE OF WIDE DYNAMIC RANGE OPERATION

摘要

A method for generating a target gain value of a wide dynamic range (WDR) operation is disclosed including: acquiring an average bright portion luminance corresponding to an average pixel luminance of a bright portion of a video image; acquiring an average dark portion luminance corresponding to an average pixel luminance of a dark portion of the video image; generating an initial gain value of the WDR operation according to a difference between the average bright portion luminance and the average dark portion luminance; and adjusting the initial gain value according to at least one of a color temperature and an exposure duration configuration value of the video image to generate the target gain value.
