3.7.2 Digital Shift in 10 bit Output Mode
No Shift
As mentioned in Section 3.1 , the
A102
k
uses a 12
bit ADC to digitize the output from the CCD
sensor. When the camera is operating in 10 bit
output mode, by default, the camera transmits bit
11 through bit 2 from the ADC.
Shift Once
When the camera is set to shift once, the output
from the camera will include bit 10 through bit 1
from the 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 100. If you changed the digital shift setting to
shift once, the reading would increase to 200.
L
Note that if bit 11 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
10 bit mode with no digital shift are all below 512.
