What's the relationship between the exposure and gain for OV5640?

[Anonymous]

Hi:

   

What's the relationship between the exposure value and gain value  for OV5640 in manual exposure mode? Is the  gain value independent of the exposure value if I turn off AEC/AGC?

   

If  I want to get best SNR for image ,that is reduce the gain value  and increase the exposure time manually,what should I do?
