Analog gain is controlled by:
• R0x35 Global Gain
The formula for gain setting is:
The analog gain range supported in the MT9V022 is 1X
6.25 percent. To control gain manually with this register, the sensor must NOT be in AGC
mode. When adjusting the luminosity of an image, it is recommended to alter exposure
first and yield to gain increases only when the exposure value has reached a maximum
limit.
Analog gain = bits (6:0) x 0.0625 for values 16–31
Analog gain = bits (6:0)/2 x 0.125 for values 32–64
For values 16–31: each LSB increases analog gain 0.0625v/v. A value of 16 = 1X gain.
Range: 1X to 1.9375X.
For values 32–64: each 2 LSB increases analog gain 0.125v/v (that is, double the gain
increase for 2 LSB). Range: 2X to 4X. Odd values do not result in gain increases; the gain
increases by 0.125 for values 32, 34, 36, and so on.
Digital gain is controlled by:
• R0x99
• R0x80
In the MT9V022, the image may be divided into 25 tiles, as shown in Figure 25, through
the two-wire serial interface, and apply digital gain individually to each tile.
