Imager Preferences 7 - 11

This parameter is only available when Image Capture Autoexposure is disabled. Exposure Time controls the 
amount of time the CCD is allowed to collect light, much like the shutter speed for a camera. Generally, the brighter 
the environment, the lower the exposure time. Set the manual exposure time to one of the following values: 5 ms, 
10 ms, 15 ms, 20 ms, 25 ms, or 30 ms. Increasing the exposure time past 20 ms in a handheld application 
increases the risk of blurring the image due to hand jitter.
