8 Basler A202k High Gain
DRAFT
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.
Shift Three Times
When the camera is set to shift three times, the
output from the camera will include bit 6 through
bit 0 from each ADC along with a zero as the
LSB.
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 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.
L
Note that if bit 9, bit 8 or bit 7 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.
Since the shift three times setting requires that the least significant bit always be
"0", no odd gray values can be output. In this case, the gray value scale will only
include gray values of 2, 4, 6 and so forth. The absence of some gray values is com-
monly called "Missing Codes”.
