Operation and Features
Shift Once
When the camera is set to shift once, the output from
the camera will include bit 8 through bit 1 from each
ADC.
The result of shifting once is that the output of the
camera is effectively doubled. For example, assume
that the camera is set for no shift, that it is viewing a
uniform white target and that under these conditions
the reading for the brightest pixel is 20. If you changed
the digital shift setting to shift once, the reading would
increase to 40.
Note that if bit 9 is set to 1, all of the other bits will automatically be set to 1. This
means that you should only use the shift once setting when your pixel readings in
8 bit mode with no digital shift are all below 128.
Shift Twice
When the camera is set to shift twice, the output from
the camera will include bit 7 through bit 0 from each
ADC.
The result of shifting twice is that the output of the
camera is effectively multiplied by four. For example,
assume that the camera is set for no shift, that it is
viewing a uniform white target, and that under these
conditions the reading for the brightest pixel is 20. If
you changed the digital shift setting to shift twice, the
reading would increase to 80.
Note that if bit 9 or bit 8 is set to 1, all of the other bits will automatically be set to 1.
This means that you should only use the shift twice setting when your pixel readings
in 8 bit mode with no digital shift are all below 64.
