An image processing apparatus comprises: an acquisition unit that divides an inputted video image into a plurality of divisions, and acquires a histogram of each of the divisions; a generation unit that generates a gradation conversion curve for each of the divisions; a determination unit that determines whether or not the inputted video image is a multi-screen video image; and a gradation correction unit that performs a smoothing process in accordance with a pixel position, to correct the gradation of the video image in each of the divisions using the gradation conversion curve of each of the divisions, wherein when the inputted video image is the multi-screen video image, the determination unit detects a position of a boundary between the plurality of video image contents, and the gradation correction unit does not perform the smoothing process within a predefined area from the boundary.
