US 8,570,348 B2 · Brightness adjuster, adjustment method, and electronic system utilizing the same

Abstract

A brightness adjuster generating an image output to a panel, which displays the corresponding image according to the image output. The image output includes a red output signal, a green output signal, and a blue output signal. The brightness adjuster includes a determination unit, a calculation unit, and a digital to analog converting unit. The determination unit determines a main input signal according to a red input signal, a green input signal, and a blue input signal. The calculation unit adjusts the red, the green, and the blue input signals according to the main input signal. The digital to analog converting unit transforms the adjusted red, the adjusted green, and the adjusted blue input signals into the red, the green, and the blue output signals.
