Acquiring a Live Image Sequence
Once you have established a serial connection with the camera and are receiving video data, you can
now grab a live image feed. Clicking the
“Live”
button, also highlighted in Figure 4, will grab a live
image sequence which you will now see in the imaging window.
Live imaging statistics are shown below the imaging window (resolution & frame rate), highlighted in
Figure 3.

Controlling the Camera
The XCAP control panel provides full control over the camera. The below sections will go through
each control tab, giving a description on how to use them on XCAP and their effect
on the camera’s
performance.
7.7.1 Gain, Exposure & Frame Period
The gain, exposure time and frame period can be controlled from the
“Gain”
tab. By default, the
auto exposure is enabled, which will automatically control the exposure time and digital gain.
Toggling the “Auto Level Control” box will disable
the auto exposure control and the user will now
be able to manually adjust these settings. The user can manually change the gain setting of the
camera between high and low gain. High gain has a smaller pixel full well capacity but offers lower
noise. The camera will be set in low gain by default. If imaging a very weak signal or for night-time
imaging, high gain would be more optimal. These controls are illustrated in Figure 5 below.
