一种自适应精确调节CCD曝光时间的方法
A Precise Method to Adaptively Adjust the Exposure Time of CCD
摘要
Abstract
A precise method to adaptively adjust the exposure time of CCD has been proposed and demonstrated based on the design of the driving circuit system and timing of ICX659ALA,a Low Light Level CCD. The method takes the CCD read clock as the unit to adjust the exposure time. It improves the system's responsiveness and ability to adapt to the outside world. Field programmable gate array(FPGA)is chosen as the hardware design platform,and driving timing has been described with Verilog. The simulation in QuartusII and experimental results tested with oscilloscope show that the designed driving timing can precisely adjust the exposure time.关键词
