Dear inivation Team,
I am currently using a DAVIS346 Mono and am examining how to adjust the event threshold settings so that the thresholds for brightness increase (ON events) and brightness decrease (OFF events) are the same value.
According to the documentation:
Understanding and Computing Biases explains that the bias value is determined by both coarse and fine values.
Thresholds for ON and OFF Events mentions that the thresholds is determined by the ratios "diffOn bias / diff bias" and "diff bias / diffOff bias".
Based on this, my understanding is that setting these ratios equal should make the ON and OFF thresholds same. Is this interpretation correct?
Additionally, I would like to know how to properly configure the parameters in the DV software to achieve this balance.

I guess that the following parameters affect the ON/OFF thresholds:
DIFF COARSE, DIFF FINE, ON COARSE, ON FINE, OFF COARSE, and OFF FINE.
However, I am not sure how each should be adjusted to make the ON and OFF thresholds equal.
I have attached a screenshot of my current bias settings for your reference.
Thank you very much for your time and support.
I would greatly appreciate any guidance you can provide.
