Abstract

An image processing apparatus includes a histogram computation section that for a plurality of images with different light exposure amounts captured, computes for each of the images a histogram of the number of pixels a light exposure amount ratio computation section that, based on a degree of similarity between a profile of a first histogram computed from a first image out of the plurality of images and a profile of a second histogram computed from a second image out of the plurality of images, computes as a light exposure amount ratio a ratio between a light exposure amount for the first image and a light exposure amount for the second image, and a pixel value adjustment section that adjusts the pixel values of pixels contained in one image out of the first image and the second image based on the light exposure amount ratio.
