摘要：
It is an object of the present invention to provide a visual processing device that achieves gradation processing that further enhances the visual effect. The visual processing device 1 is a visual processing device that performs gradation processing for each image region of an input signal IS, and is provided with an image partitioning portion 2, a gradation transformation curve derivation portion 10, and a gradation processing portion 5. The image partitioning portion 2 and the gradation transformation curve derivation portion 10 use a brightness histogram Hm of a wide area image region Em to create a gradation transformation curve Cm of the image region Pm. The gradation processing portion 5 performs gradation processing of that image region Pm based on the gradation transformation curve Cm that has been derived.
