Controlling The Camera (Xcap); Exposure And Gain Control - Raptor Photonics HAWK 252 User Manual

8. CONTROLLING THE CAMERA (XCAP)

The sections below give information on using each control of the Hawk 252, giving a
description on how to use each control parameter and their effect on the camera's
performance. The software used to illustrate the camera controls is XCAP.

8.1 Exposure and Gain Control

The exposure and gain (EM and digital) can be controlled automatically by using the
Automatic Light Control (ALC). When the ALC is enabled, the camera will automatically
adjust the exposure and gain of the camera based on the ALC parameters set. Adjusting the
ALC parameters is discussed in section 8.3.
If the ALC is disabled, the user will be able to select EM and digital gain values. Please take
great caution when manually controlling the EM gain. Using excessive levels of EM Gain
when not required can possibly cause damage and aging of the sensor. Raptor recommends
using the ALC to automatically control the EM gain.
The gain controls are shown in Figure 6.
