    • A pair of gamma1A and gamma2A converter circuits (1a,2a) to a pair of gamma1C and gamma2C converter circuits (1c,2c) use first to third types of first and second gamma characteristics to gamma convert an input video signal (IS). Selectors (3 to 5) select one pair among three pairs of gamma characteristics in accordance with a transmittance to be used for display, and select one of the six gamma corrected outputs such that both a distribution area ratio of pixels driven by the video signal as gamma corrected by use of the first gamma characteristic of the selected pair of gamma characteristics and a distribution area ratio of pixels driven by the video signal as gamma corrected by use of the second gamma characteristic of the selected pair of gamma characteristics are equal to a distribution area ratio specified in advance for the selected pair of gamma characteristics.
    • 一对gamma1A和gamma2A转换器电路(1a,2a)到一对gamma1C和gamma2C转换器电路(1c,2c)使用第一和第三类型的第一和第二伽马特性来伽马转换输入视频信号(IS)。 选择器(3至5)根据要用于显示的透射率在三对伽马特性中选择一对,并选择六个伽马校正输出中的一个,使得由视频信号驱动的像素的分布面积比为 通过使用所选择的一对伽马特性的第一伽马特性校正的伽马和由视频信号驱动的像素的分布面积比是通过使用所选择的伽马特性对的第二伽马特性校正的伽玛等于分布 面积比对于所选择的伽马特性对预先规定。
