Note: In Manual mode and Once Bright mode, the brightness setting must be updated as the
camera temperature changes. To avoid this issue, it is recommended to use Automatic or Auto-
Bright modes when possible. Also, only in the 8-bit mode will selecting AGC mode affect the
digital data output.
Linear Parameters: The Linear Parameters are used for fine tuning the Auto Bright, Once
Bright and Manual modes. Each of their settings is described accordingly in detail above.
AGC Parameters: The AGC Parameters are used tuning the Automatic, Linear Histogram and
Logarithmic modes. Each of their setting is described accordingly in detail above.
Region Of Interest: The Photon camera allows the user to select the Region Of Interest that
which the AGC will use for it's calculations. This Region Of Interest or ROI can be set for
either the entire frame size or some other portion as shown below in Figure 19. The settings are
similar to an X-Y coordinate system with 0,0 in the middle. Refer to the section for Pan & Zoom
on Page 4 for detail information on how these features work together.
