Abstract
An image processing apparatus includes an input unit for inputting an image, a division unit for dividing the inputted image into a plurality of divided regions, an obtaining unit for obtaining a feature amount of the image for each of the divided regions, a generation unit for generating a compression curve for each divided region, and a compression unit for generating an output image by performing compression of a dynamic range using the compression curve for each of the divided regions. The generation unit generates the compression curve for each of the divided regions so that a slope of the compression curve for each of the divided regions matches in a range from a luminance of a dark region of the image to a luminance of a predetermined brightness.
