Abstract:The image-collection system is introduced based on video sync separator LM188. Through LM1881, such as composite sync,vertical sync and odd/even can be accurately separated from video signal. It provided guarantee to control of image-collection. Taking example for the application of LM1881 in image-collection, this article particular introduced the design of image-collection system, which included hardware design and software design.
Keywords:LMl881
