Abstract:
An input pixel value setting circuit sets at least two different input pixel values in a subject area of an input image. A dynamic range transforming circuit performs a process for transforming pixel values of the input image using a dynamic range transformation function in which output pixel values corresponding to the two different input pixel values become set output pixel values.
