According to one aspect of the present invention, there is provided an image processing device that performs brightness conversion processing according to a brightness conversion coefficient on each pixel of an input image and produces an output image. The image processing device includes a division section dividing the region of the input image into a plurality of areas and a histogram calculation section calculating a histogram for each area. Here, the brightness conversion coefficient is determined based on the result of calculation by the histogram calculation section. With this configuration, it is possible to obtain, even when there is a portion of an image having a brightness level (or a brightness range) of low frequency in terms of an entire image, satisfactory contrast for the entire image including such a portion. |
