Rolera Bolt USER MANUAL
Understanding the LED Indicators
The LED indicators at the back of the camera give you important information about what your camera is doing:
■
GREEN:
The green LED is the power indicator. This LED should always be lit when the camera is
connected to your computer and is turned on.
Capturing Images with the Rolera Bolt
Consult your imaging application’s user’s manual for more details.
Basic Camera Parameters
Gain Controls
The Rolera Bolt’s electrical gain controls allow the user to map an image’s intensities of interest to the camera’s
digital range. This mapping is performed in the analog domain and thus avoids the quantization errors
incurred when the mapping is performed in the digital domain.
Most users wish to operate the camera in a mode that maximizes dynamic range. The factory default electrical
gain is a calibrated value that maximizes the dynamic range. The electrical gain can be controlled in software
by the CMOS Gain controls.
Exposure Controls
The Rolera Bolt’s exposure controls allow the user to adjust the integration time for each acquisition. By
increasing the exposure time, more light is captured by the CMOS sensor and the signal to noise ratio is
increased.
