About gain setup of cmos sensor MT9P031

Hello everyone !!

I found the formula of the effective gain in the datasheet is

 (((Blue_Digital_Gain/8) + 1) * (Blue_Analog_Multiplier + 1) * (Blue_Analog_Gain/8))

 

and the data range is 

Blue Digital Gain : 0~120

Blue Analog Multiplier: 0~1

Blue Analog Gain : 8~63

 

so the least value of the gain is 1

 

How to configure the gain to the value less than 1

 

Thanks!!

Ask Aptina tech support. It's a sensor config issue, not an FPGA problem.
