摘要： The image processing device includes a luminance modulator, a backlight control gain adjustment unit, a peak value detector, and a histogram detector. The peak value detector calculates a peak value as a maximum luminance value in a prescribed region of the video input signal inputted. The histogram detector calculates frequency distribution about the luminance value of the video input signal. Based on the peak value calculated by the peak value detector and the frequency distribution calculated by the histogram detector, the luminance modulator converts a luminance value of the video input signal into a luminance value of the video output signal and outputs the video output signal, for every pixel. The backlight control gain adjustment unit creates the backlight control signal based on the peak value.
