摘要

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.

1. A display apparatus comprising:
a signal processing section configured to receive input image signals and display the input image signals in different frames; a gamma processing section configured to transform input image signals into a current displayed frame of the input image signals and a subsequent displayed frame of the input image signals, said input image signals including signals of primary colors; an image analysis section configured to extract an extension coefficient from said current displayed frame of the input image signals, said extension coefficient being used to convert said subsequent displayed frame of the input image signals into extended signals of the primary colors, wherein said extended signals of the primary colors are used to calculate a signal of a different color, said extended signals of the primary colors and said signal of the different color being used to calculate other signals of the primary colors, wherein said subsequent displayed frame of the input image signals occurs after said current displayed frame of the input image signals.
