Image output and input systems

An image output/input system, comprising:

• a phase comparator for receiving a digital signal and a vertical synchronous signal and comparing their period and phase to generate a clock correction signal, wherein the digital signal is converted from an analog signal through an analog-to-digital conversion;
• an image synchronous signal generator for receiving the clock correction signal, generating the vertical synchronous signal, and adjusting a subsequent period of the vertical synchronous signal according to the clock correction signal;
• a sensor timing generator for receiving the vertical synchronous signal and generating the sensor control timing according to the vertical synchronous signal;
• a sensor for receiving the sensor control timing and generating raw image data after acquiring images;
• an image/color processing unit for receiving the raw image data and dealing with the image and color process of the raw image data to generate target image data;
• and
• a video encoder for receiving the vertical synchronous signal and the target image data and encoding the vertical synchronous signal and the target image data to generate analog encoded image data.
