Abstract: This paper describes a pseudo-color TV frame grabber in detail. The system has the function of resolution control, sequential image grabbing, display and store. Because the system is synchronized with TV field synchronization, It can finish the grabbing and display of 512×512×8 bit image within 40ms. The pseudo-color output of system can greatly enhance man’s understanding accuracy of the picture. The system has the features of high speed, real-time and simple operation. It can be used in biomedical engineering, remotely sensed image
processing and industrial inspection, etc.
