A CCD image sensor frame grabber

摘要

A system interface is described for a specific CCD image sensor that digitizes and collects the image from the sensor for storage in a personal computer. The output of the CCD image sensor is fed through an 8-bit flash analog-to-digital convertor and stored in a buffer memory. During the next integration period the image is loaded into the computer and processed. The system allows the imager to utilize the full silicon area and eliminates the need for mechanical shutters normally required to use CCD sensors of this type.
