一种伪彩色显示的数字图像采集系统

介绍一种伪彩色显示的图像采集系统。该系统具有分辨率可调，序列图像摄取、显示、存储等功能。由于系统的工作同步于视频场，使得该系统可以在40ms 内完成一幅512×512×8bit 图像的摄取和显示。此外，伪彩色增强电路的实现，可大大提高人们对图像的辨识能力。该系统具有速度快、实时性强、操作简单等特点。它可广泛应用于生物医学工程，卫星遥感图像处理及工业检测等领域。

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.
