Abstract
Disclosed herein is a display apparatus including: a display pixel section including pixels each composed of an arrangement of red, green, and blue subpixels and an additional subpixel of a specified color; and a signal processing section configured to extend signal levels of an input image signal, extract a signal component of the specified color from extended red, green, and blue signals, determine a signal level of the specified color, perform an extension process based on the signal level of the specified color, modulate the red, green, and blue signals subjected to the extension process in accordance with a specified modulation level so as to have different brightness from that of an original image, and modulate brightness of a light source. The input image signal used to determine the modulation level and the input image signal subjected to a modulation process and displayed are of different frames.
