| Abstract: | This paper presented an area array CCD image sensor driver design for corneal image capture system development.Sony ICX424AL area array CCD was chosen as image sensor,and the driving timing characters were analyzed.Main circuit module works and related circuitry registers control way of the high-performance analog front-end processing chip AD9949A were introduced.The ICX424AL driver design was realized by using the CPLD and AD9949A.The final results show that,CCD can produce right analog signal output.The digital video signal can be obtained by computer,with exceptional image effects. |
