Abstrꢀct: An algorithm of detecting and tracking moving target in color images which were captured by camera was  
proposed. Firstly, a series of color images were changed into gray images and several kinds of image-sharpening  
methods were studied and compared. Secondly, the video sequences were differentiated and threshold segmentation  
was done in order to separate the moving target from the background. At last, the size and position of the moving  
target were acquired by projection method. The experimental results showed that the method of moving target detect-  
ing and tracking was simpleꢁ effective and high real time.
