ABSTRACT:
The present invention is a high resolution charge-coupled device (CCD) camera system having a CCD camera which is capable of operating at a low data rate (e.g., 1 to 2.5 MHz) that is compatible with the input data rate of a computer. An output of the CCD camera is coupled through an analog-to-digital converter (A/D) to an input of the computer which receives and analyzes the output of the camera. The CCD camera contains a CCD image sensor which is a two phase sensor capable of operating in a mode where holes are accumulated at room temperature so as to reduce the dark current generated in the sensor. Thus, the CCD camera system is of simple construction so as to be relatively inexpensive and can operate at room temperature with reduced dark current.
