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.

Abstract: An image processing method and device thereof are provided. The device includes a capture device and a processor. The capture device is adopted for receiving a plurality of frames and comparing at least two adjacent frames to obtain an area selection signal according to a differential value there-between. The processor is connected to the capture device for receiving the area selection signal and to separate each of the adjacent frames into at least two areas. Each of the areas of the adjacent frames is performed by an image processing step respectively, and then the images of the areas are combined to obtain a resulted frame.
