IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD, AND STORAGE MEDIUM

摘要

It is possible to adjust brightness of an image for which contrast correction has been performed for each local area. An image processing apparatus that adjusts brightness of a processed image for which contrast correction for removing a scattered light component has been performed for each local area, including: an estimation unit configured to estimate luminance of the processed image based on luminance of an input image before the contrast correction is performed for each local area and transmittance corresponding to the luminance; a parameter calculation unit configured to calculate an exposure correction parameter based on the luminance of the input image and the luminance of the processed image estimated by the estimation unit; and an exposure correction unit configured to perform exposure correction for the processed image by using the exposure correction parameter.
