Camera Settings
Camera settings can only be changed by the web interface. It is possible to change the exposure time,
the gain of the different color channels, image flipping and Bayer mode. Gain values for the color
components can be used for color correction.
Exposure
sets the exposure time of the sensor.
Gain
global gain for all color channels
Red gain
gain for all red pixels
Blue gain
gain for all blue pixels
Green gain 1 and 2
gain for green pixels in even and in odd lines, values should be
identical
horizontal and
vertical flip
can be used to correct the image orientation according to
mounting position of the camera. Changes Bayer mode, which is
fixed yet. See below.
Bayer mode
because the flipping will change the starting pixels the Bayer
mode the mode has to be adjusted if flipping is done. In streaming
mode this setting has no effect.
Sleep between
snaps
only used in webcam mode, not in streaming mode
Automatic gain
correction
enables the automatic exposure control
Flicker-free
exposure
if 0 no flicker-free exposure is used. Gain is fixed to a medium
value and exposure is controlled by changing the exposure time
For values > 0 exposure time is limited to multiples of the value.
Exposure values in between are realized by changing the gain.
For 50Hz lighting flicker-free exposure is realized with a value of
820. For 60Hz the value should be set to 683.
Average grey value The average gray value of the whole image, the exposure control
tries to reach.
Color saturation
color saturation of the result image in percent. 0 is black and
white, 100 neutral. The maximum lies at 200.
Button: “White
balance once”
if pressed the software calculates RGB parameters that set the
current scene to neutral white. This will take several seconds.
