CCD CAMERA
OVERVIEW
Refer to Figures 1 and 21 for the location of the CCD camera.
The 9600 uses a CCD (Charge Coupled Device) Camera which produces a video signal
of the image it receives from the image intensifier output. The CCD sensor is an analog
IC that uses an array of photosensitive elements to convert a variety of light levels into a
proportional electrical charge. The brighter the light, the greater the electrical charge.
Each photo element in the array stores an electrical charge. Electronic circuitry on the
CCD camera PCB sequentially shifts these electrical charges to an output gate creating
an output signal. The output signal is an analog representation of the image displayed
on the output of the I.I. The analog video signal is combined with the sync signals on the
CCD PCB, creating a composite video signal. This composite video signal leaves the
camera at P2 for processing and display.
