If you know the integer setting for the gain, you can calculate the resulting dB of gain that the
camera will achieve by using the following formula:
Setting the Gain
You can set the gain with the Camera Configuration Tool Plus (CCT+) or by using binary write
commands from within your own application to set the camera’s control and status registers
(CSRs).
With the CCT+
With the CCT+ (see Section 7.1 on page 156 ), you use the Gain parameter in the Gain & Offset
parameters group to set the gain.
By Setting CSRs
You set the gain by writing a value in dB to the Absolute Gain field or by writing an integer value to
the Raw Gain field of the Gain CSR (see
page 173 ).
Section 7.2.2 on page 164 explains CSRs and the difference between using the “absolute” field and
the “raw” field in a CSR. Section 7.3.1 on page 197 explains using read/write commands.
6.1.2 Offset
Offset is adjustable on an integer scale that ranges from -4095 to +4095. The default setting is 0.
If the camera is set for an 8 bit video data output mode:
„
increasing the integer offset setting by 16 will increase the digital pixel values output from the
camera by 1.
„
decreasing the integer offset setting by 16 will decrease the digital pixel values output from the
camera by 1.
If the camera is set for a 10 bit video data output mode:
„
increasing the integer offset setting by 4 will increase the digital pixel values output from the
camera by 1.
„
decreasing the integer offset setting by 4 will decrease the digital pixel values output from the
camera by 1.
If the camera is set for a 12 bit video data output mode:
„
increasing the integer offset setting by 1 will increase the digital pixel values output from the
camera by 1.
„
decreasing the integer offset setting by 1 will decrease the digital pixel values output from the
camera by 1.
