Shift Twice
When the camera is set to shift twice, the output
from the camera will include bit 9 through bit 2
from the 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.
Shift Three Times
When the camera is set to shift three times, the
output from the camera will include bit 8 through
bit 1 from the ADC.
The result of shifting three times is that the output
of the camera is effectively multiplied by eight.
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 three times, the reading would
increase to 160.
L
Note that if bit 11 or bit 10 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 read-
ings in 8 bit mode with no digital shift are all below 64.
L
Note that if bit 11, bit 10 or 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 32.
