Digital clamp

You can adjust b255 and 0 steps for 12-bit 
output images.
With the value of 1023 (default value) at 0 step, you can 
adjust to +255 step by entering 0.

5.3.

Digital gain

Configure this setting with DGAIN. Set the variable 
between x0 (black) to x15 and set the factor between 0 
and 15, and Yout = Yin x factor.
Multiply by one when the factor is equal to 1.
Use this, for example, when the image is dark with 
regards to AFE gain only. 

5.4.

Digital pedestal

You can adjust between -255 and +255 steps for 12-bit 
output images.
With the value of 1023 (default value) at 0 step, you can 
adjust to -255 step by entering 0, and to +255 step by 
entering 2047.
This setting raises the whole level.

Note

The digital gain changes the whole level. Therefore, if it 
is used when the previous step of the digital clamp has 
been changed from the default value (1023), the change 
in the black level will be (digital gain factor) 

×

 (digital 

clamp additional value).
If the digital clamp setting has been changed, use the 
digital pedestal to adjust the black level.
