ABSTRACT:
An apparatus and a method for gain adjustment for analog YPbPr signals are provided. The apparatus comprises a first clamping circuit, an analog-to-digital converter (ADC), and a gain calculator. The first clamping circuit clamps the lowest potential of a horizontal synchronization signal of a Y signal of an analog YPbPr signal to 0 V. The ADC converts the clamped Y signal from an analog signal to a digital signal and then outputs the digital signal. The gain calculator receives the actual peak-to-peak voltage of the horizontal synchronization signal from the ADC, and then calculates and sets the gain for the ADC according to the peak-to-peak voltage.
