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 along with two
zeros as LSBs.
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 100. If
you changed the digital shift setting to shift
twice, the reading would increase to 400.
L
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 with no dig-
ital shift are all below 256.
Since the shift twice setting requires that the two least significant bits always be "0",
the gray value scale will only include every 4th gray value. For example, 4, 8, 16
and so forth.
