ABSTRACT:
A first lower-range generating portion generates a pixel value of an output image based on a first nonlinear function in a first lower range where a pixel value of a subject pixel is lower than a predetermine value. The first upper-range generating portion generates the pixel value of the output image based on a first monotonically increasing function in a first upper range where the pixel value of the subject pixel is greater than or equal to the predetermine value. The pixel value of the output image increases toward a first maximum output luminance value as the pixel value of the subject pixel increases. The first maximum output luminance value is greater than a luminance value obtained by correcting a maximum pixel value of the original image based on the first nonlinear function. The first maximum output luminance value is proximate to the maximum pixel value of the original image.
