4.3 Adjust the Sensor Gain

Gain settings are like the ISO settings in most digital cameras. The gain is divided into

analog and digital gain, and there are separate gain settings for four color-specific gains. There is

also global gain setting to change all the four color-specific gains.

Here we demonstrate how to change the gain through the analogue_gain_code_global_

register (0x3028 in hex, 12328 in decimal). Given the exposure register 0x3012(12306) is 10.
