Abstract
A histogram generator generates a histogram based on luminance values of respective pixels of an image. The histogram represents a relationship between each of the luminance values of the image listed in a predetermined axis and the number of pixels for the corresponding one of the luminance values. An image corrector calculates, based on the histogram, a luminance increment caused by the light reflected from the cover member, and translates, based on the luminance increment, the histogram in a negative side of the predetermined axis of the histogram to accordingly generate a corrected histogram. The corrected histogram has (i) an estimated least luminance value lower than the least luminance value, and (ii) an estimated most luminance value lower than the most luminance value. The image corrector generates, based on the corrected histogram and the image, a corrected image.
