Parameter Description
Frame Rate (in Hz) Specifies the internal trigger frame rate for free run mode, in Hz.
Possible values range from 0.1 to 20.0 Hz for Genie C1024 in full scan mode.
(Note: the Sapera SDK specifies the frame rate in milli-Hertz).
Gain (in dB) Specifies the sensor analog Gain factor, in dB. Possible values range from
–6.0 to 12.0 dB, in 0.1 dB increments. For more information, see
" Gain and Black Level

Color Calibration
The Genie color series of cameras, designed for machine vision applications, do not implement a dynamic full time
white balance function. Unlike consumer digital cameras which have automatic white balance, the machine vision
environment typically uses constant lighting with known color spectra. The Genie RGB gain settings are adjusted to
optimize the illumination with the spectral response of the Genie model used.
CamExpert provides a color calibration tool for manual RGB gain control or an automatic white balance function.
The adjusted RGB gain settings remain active until the Genie is powered off. RGB gain settings can be saved and
recalled with other parameters in the Genie user defined power up settings (see
" Power-up Configuration " on page
32 for details on configuring Genie to power up with user set parameters).
CamExpert Color Calibration Menu
The CamExpert Color Calibration dialog provides an automatic white balance function plus manual RGB gain
controls. Adjustments made are lost on power off unless saved using the Genie power up user settings function.
