摘　　要：提出了一种提高某型判读仪CCD(chargecoupleddevice)数字图像采集速度的方法。利用阻尼和胶片压紧装置,清除了胶片瞬间停止时的抖动现象。从工作方式和时序分析入手,通过改进现有程序,使工作方式由原来的开环控制变为闭环控制,节约了大量主控微机机时,使其图像采集速度提高6倍以上,并增加了图像回放功能,提高了某型判读仪的整机性能指标。A method for improving the CCD digital image collection speed of a certain interpretoscope is presented. The shaking phenomenon of films at the instantaneous cease is solved by means of damping and film pressing device. Based on the working-mode and time-sequence analyses, the original open-loop control is changed into closed-loop control by modifying the existing program, thus the running time of main control microcomputer is greatly reduced, the digital image collection speed is increased by 600%, the image replay function is added, and the overall performance of the interpretoscope is improved.
