Integration Mode
When integration control signal is low, the CCD imager
keeps integrating and when the signal returns to high, it
enables the charge transfer for video output. This mode
integrates longer than one field and with strobe light
application, it can capture randomly strobed images dur-
ing the integration. It also increases the exposure time
to enhance low light viewing.
