Illumination
The IS4910 camera has an integrated illumination system. In the snapshot mode of operation, the
minimum and maximum illumination flash time can be specified. Note that the maximum illumination flash
time in the snapshot mode always equals the image integration (exposure) time, see function
camSetIntegrationDuration() for details.
Illumination can be enabled or disabled. By default, if not specified otherwise in the IS4910 device driver
initialization file VuQuest2D.ini, illumination is enabled and the minimum illumination flash time (for
snapshot operations) is set to 0.
To enable or disable illumination while the camera is running in the video mode, the camera must be
stopped.
