Description
Counter increments by 1. Use this value to
verify that every line is output
Use these values to help calculate line
average and gain
Monitor these values (either above or
below threshold ) and ad just camera
d igital gain and background subtract to
maximize scene contrast. This provid es a
basis for automatic gain control (AGC)
Use these values to focus the camera.
Generally, the greater the sum the greater
the image contrast and better the focus.
