The invention relates to a still image collection system for collecting black and white composite picture signal for use in space test. It consists of a video input circuit, a synchronizing separator circuit, A/D converter, image data storage circuit, a collection time sequence control circuit, a transmission control circuit, and a central control processing unit. The invention features: collection process is completed by using pure hard circuit, and there is no outside interference signal in the collection process; the sequence number of the collected pixel row and pixel column can be modified by reloading the codes in EEFROM chip. |
