Sensitivity Mode and Pixel Readout

The camera has the option to operate in either high sensitivity or low sensitivity mode or
in tall pixel mode. When in high sensitivity mode, the camera uses both line scan sensors
and its responsivity increases accordingly. When in low sensitivity mode, the camera uses
the bottom sensor. When operating in tall pixel mode, the camera operates using both
sensors, creating a 28µm x 14µm pixel. The sensitivity mode is software controlled
through QuickCam or through the ASCII command ssm.
