Basler aviator Camera Link 135
When the camera is set to shift by 4, the 4 least significant bits output from the camera for each
pixel value will be 0. This means that the gray value scale will only include every 16th gray value,
for example, 16, 32, 48, 64, and so on.
If the pixel values being output by the camera’s sensor are high enough to set bit 8, bit 9, bit 10, or
bit 11 to 1, we recommend not using shift by 4. If you do nonetheless, all bits output from the camera
will automatically be set to 1. Therefore, you should only use the shift by 4 setting when your pixel
readings with a 12 bit pixel format selected and with digital shift disabled are all less than 256.
7.9.2 Digital Shift With 10 Bit Pixel Formats
No Shift
As mentioned in the Functional Description section of
this manual, the camera uses 12 bit ADCs to digitize
the output from the imaging sensor. When the camera
is set for a pixel format that outputs pixel data at 10 bit
effective depth, by default, the camera drops the two
least significant bits from each ADC and transmits the
10 most significant bits (bits 11 through 2).
Shift by 1
When the camera is set to shift by 1, the output from
the camera will include bit 10 through bit 1 from each
ADC.
The result of shifting once is that the output of the
camera is effectively multiplied by 2. 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 by 1, the
reading would increase to 200.
If the pixel values being output by the camera’s sensor are high enough to set bit 11 to 1, we
recommend not using shift by 1. If you do nonetheless, all bits output from the camera will
automatically be set to 1. Therefore, you should only use the shift by 1 setting when your pixel
readings with a 10 bit pixel format selected and with digital shift disabled are all less than 512.
