Image signal processing method, image signal processing apparatus, and image displaying apparatus

摘要

An image signal processing method for performing nonlinear compensation on an image signal to be fed into a display device ( 103 ). The characteristics of nonlinear compensation are changed according to the brightness of a place in which the display device ( 103 ) is installed. This method can make the characteristics of brightness of human beings feel linear with respect to an image signal, even when the display luminance of the display device ( 103 ) is uniformly increased by the influence of ambient light.
