摘要： An image signal processing method adapted to an AFE device, which respectively generates first and second colors of digital signals according to first and second colors of analog signals. First, the first color of odd and even signals and the second color of odd and even signals are generated according to the first and second colors of analog signals, respectively. In a single channel mode, the first color of odd or even signal serves as the first color of digital signal for output, and the second color of odd or even signal serves as the second color of digital signal for output. In a dual channel mode, the first color of odd signal and second color of even signal are synchronously outputted, and the first color of even signal and second color of odd signal are also synchronously outputted. The first color of odd and even signals are combined to form the first color of digital signal, and the second color of odd and even signals are combined to form the second color of digital signal.

摘要： A sync signal acquisition device is disclosed which comprises a transistor, a resistor, a clamper, an analog multiplexer and a comparator. While operating in a composite HS mode, prior to the generation of the sync signal HS, the invention uses a conventional circuit to extract a composite sync signal at start-up, thereby allowing related circuits to generate the sync signal HS and a clamping signal. Then, a mode selecting signal is used to disable the automatic clamping mode and switch the analog multiplexer to a forced clamping mode. At this point, the output voltage of the damper is set by a user instead of process; accordingly, the DC voltage level is more controllable, but not subject to drift due to process changes or temperature changes.
