Abstract
A signal processing circuit comprising: a signal separation unit separating an input video signal into components of individual colors; an expanded video signal generation unit performing an expansion process for increasing a signal value of the input video signal, and outputting data obtained by the expansion process as an expanded video signal; an expansion coefficient decision unit deciding an expansion coefficient to be used for the expansion process; and an output video signal generation unit generating an output video signal for output to the display panel based on the expanded video signal. The expansion coefficient decision unit decides the inverse of the saturation as the expansion coefficient for a pixel, at which the saturation is not smaller than a predetermined value, and decides the expansion coefficient based on a quadratic function.
