Abstract
An image output/input system includes a phase comparator, an image synchronous signal generator, a sensor timing generator, a sensor, an image/color processing unit, and a video encoder. The phase comparator receives a digital signal and a vertical synchronous signal and compares their period and phase to generate a clock correction signal. The image synchronous signal generator receives the clock correction signal and adjusts a subsequent period of the vertical synchronous signal according to the clock correction signal. The sensor timing generator receives the vertical synchronous signal and generates the sensor control timing, and the sensor receives the sensor control timing and generates raw image data. The image/color processing unit receives the raw image data and deals with the image and color process of the raw image data to generate target image data. The video encoder receives the vertical synchronous signal and the target image data and encodes them to generate analog encoded image data.
