Hi!

We recently acquired a EVK3-VGA and I have a question about its minimal contrast sensitivity. I am wondering what the minimal contrast sensitivity this sensor could achieve? I found there are different numbers (12% and 25%) in three references (please see the attached screenshot figure below): which one is right?

I know we could modify the bias_diff_on and bias_diff_off to increase the sensitivity. But do you know what is the extreme limit the sensor could achieve(could it be smaller than 12%?)? And what are the values for the bias_diff_on and bias_diff_off?

How does the Gen4 sensor compare to the Gen3? I found the nominal contrast sensitivity is 15%.

Thank you so much for your help in advance! Looking forward to hearing your reply.

Best,

Ning
