Image processing apparatus that performs gradation correction of photographed image, method of controlling the same, and storage medium

摘要

An image processing apparatus capable of reducing processing load by determining whether or not to perform gradation correction, according to a difference or a ratio between feature values of object areas, and generating an excellent image by performing gradation correction. An image dividing section divides an input image into a plurality of predetermined object areas. A feature value calculation section and a determination section compare the feature values indicative of features of the respective object areas, obtain a luminance level difference, and determine whether or not the difference is within a predetermined range. When the difference is within the predetermined range, an image processing section and a system controller perform area-by-area tone mapping on respective images of the areas to form a synthesized image.
