| 摘 要： | 现研究的是基于DM642的视觉假体图像采集与处理系统，是视觉假体微机电系统的初步模拟，是利用高端数字图像处理芯片和CMOS图像传感器开发的一个系统。这样的一套系统是设想在正常人眼的视网膜不能正常工作时对它进行代替。由CMOS图像传感器采集视频信号，经过高端的数字图像处理芯片的处理，并行输出电极刺激信号。

| Abstract: | The image acquisition and processing system based on DM642 is the initial simulation of micro-electro-mechanical system in the visual prostheses,which is developed by use of advanced digital image processor chip and CMOS image sensor.If the eyes' retina is abnormal, the system is substituted for it.The video signal is acquired by CMOS sensor.Then it is transformed to the output signal through the advanced digital image processor chip. |
