【Abstract】 An image processing system for Low-Light-Level TV is introduced in this paper.In the system,a hybrid algorithm combined with noise removing,image sharpening and contrast enhancement is adapted,and implemented by using pipeline structure and parallel structure.The system makes a full use of the sources of the large-scale programmable devices and the DSP processor,and thus it implements the image processing in real time. The system is proved to have excellent performance in the field test.更多还原
