Patent ID: 7671897

Claim:
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 generated from a light source or a power source 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 that is adjusted to synchronize with the analog signal in frequency and phase 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, wherein the sensor control timing is synchronized with the analog signal to allow the time point of exposure of the sensor to synchronize with the analog signal; 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.
