摘要：
A visual processing device that achieves gradation processing and further enhances a visual effect. The visual processing device 1 performs gradation processing for each image region of an input signal IS, and includes 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 an image region Pm. The gradation processing portion 5 performs gradation processing of the image region Pm based on the derived gradation transformation curve Cm.
