Gain Raw Tap 1 sets an additional amount of gain for the even numbered pixels in the sensor (pixels
0, 2, 4, 6, etc.). The total gain for each even numbered pixel will be the sum of the Gain Raw All
parameter value plus the Gain Raw Tap 1 parameter value.
Gain Raw Tap 2 sets an additional amount of gain for the odd numbered pixels in the sensor (pixels
1, 3, 5, 7, etc.). The total gain for each odd numbered pixel will be the sum of the Gain Raw All
parameter value plus the Gain Raw Tap 2 parameter value.
The minimum and maximum allowed Gain Raw All, Gain Raw Tap 1, and Gain Raw Tap 2 values
are shown in Table 12.
.
There are also minimum and maximum restrictions for the total gain as shown in Table 13.
.
Note that the minimum and maximum gain values allowed and the total gain allowed vary
depending on the bit depth of the current pixel data format setting. For example, for a monochrome
camera that is set for a pixel data format with an 8 bit depth, the sum of the Gain Raw All value plus
the Gain Raw Tap 1 value must be between 0 and 800 (inclusive). If the camera is set for a pixel
data format with a 12 bit depth, the sum of the Gain Raw All value plus the Gain Raw Tap 1 value
must be between 0 and 400 (inclusive)
For normal operation, we recommend that you set the value of Gain Raw Tap 1 and Gain Raw Tap 2
to zero and that you simply use Gain Raw All to set the gain. Typically, the tap gains are only used
if you want to adjust the gain balance between the even numbered pixels and the odd numbered
pixels in the sensor.
If you know the current settings for the Gain Raw All, Gain Raw Tap 1, and Gain Raw Tap 2
parameters, you can use the formulas below to calculate the dB of gain that will result from the
settings.
Even Pixel Gain = ( 0.0359 x Gain Raw All Value) + (0.0359 x Gain Raw Tap 1 Value)
Odd Pixel Gain = ( 0.0359 x Gain Raw All Value) + (0.0359 x Gain Raw Tap 2 Value)
