The frame rate depends on the amount of data that is transferred. If the effective image size is small, a
high frame rate can be achieved. The maximum frame rate is calculated, whenever the image size or
the binning mode changes. The frame rate slider limits are adjusted. If needed, the framerate is also
reduced, when the image size changes.

RTP
RTP streaming (see "Technical terms") can be enabled or disabled using the checkbox shown below.
Remark: RTP streaming allows image a maximum width of 2040 pixel. As the acquisition width must
have a certain granularity, for RTP the width can not exceed 1984. When the checkbox is clicked and
the binning mode is "1", the acquisition width is corrected accordingly.

Gain control
Gain control can be done automatically or manually. For automatic gain control, the pixels in the gain
control window are used. The gain control algorithm tries to adjust the image brightness so that the
average grey value is reached inside the gain control ROI.

Flicker-free exposure is nice in a room with artificial illumination. Choose the power frequency used in
your country (e.g. 50Hz in Germany).
For outdoor illumination best is to use "not flicker free". This allows the algorithm to use a wider range
of exposure times.

Flicker free setting for automatic gain control
With manual exposure, the exposure time and the gain for red, green and blue pixels can be choosen
manually. The gain values can be 0-1024, the exposure time is 1-10000000
