IMAGING DEVICE, IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, AND IMAGE PROCESSING PROGRAM

摘要

An imaging device includes: an index calculation unit for calculating the natural light index representing the outdoor imaging degree by the natural light, a brightness ratio index representing a dynamic range, and an exposure index; a brightness compensation amount calculation unit for setting a temporary correction amount for the captured image data according to a brightness analysis value of the captured image data and a brightness reproduction target value, setting a mixture coefficient as a weight coefficient to be multiplied on each of the temporary correction amounts according to the natural light index, and calculating the brightness correction amount of the captured image data according to the mixture coefficient and the temporary correction amount; and a brightness correction curve generation unit for generating a brightness correction curve for converting the captured image data according to the brightness correction amount and the respective indexes calculated by the index calculation unit.
