摘　　要：该文研究利用硬件电路实现图象伪彩色处理的方法，突破了传统的图象伪彩色处理必须利用计算机软件的局限。通过对黑白视频信号进行灰度分割和编码，建立起灰度级──彩色的变换关系，即某一灰度级经过变换编码后对应于一个特定的彩色，并且连续的灰度级变化对应于连续的彩色变化，通过彩色编码合成为彩色全电视信号，从而可以直接在彩电上显示出伪彩色图象。该方法线路结构简单，实现了实时伪彩色处理，大大提高了人眼的分辨能力。In this paper,the method of using electric circuit to carry out real-timepseudo-color image processing is introduced,this design method breakes through the traditional limit that it must depend on software to bring about pseudo-color image processing.By converting black-and-white video signal into digital signal and coding,the functional relationship between brightness and color is established,i.e. by coding any grey lev-el is defined as a special color,and the color will vary continuously with the continuousvariation of greylevel,then composite color television signal is composed by color coder,so pseudo-color image can be displayed directly on color TV screen. This design not onlyhas a simple structure,but also realizes real-time image pseudo-color processing.The resolution of human eyes woumbe improved effectively.
