1 Setup the bayer pattern of the sensor. This setting is only visible if “Engineering
Mode” is enabled on the info tab and usually should not be changed by the user.
2 Manually set the shutter time in microseconds. Can only be adjusted if auto
exposure is disabled. Use the Combo Box and the “+” and “-” buttons to the right
of the slider to switch between common exposure time presets.
3 Manually set the sensor gain (ISO). High values will lead to a brighter image bat
also more noise. Can only be adjusted if auto exposure is disabled. Use the
Combo Box and the “+” and “-” buttons to the right of the slider to switch between
common ISO presets.
4 Enable auto exposure. This will automatically adjust shutter time, ISO and aperture
(if available). Turn off to use manual settings (see points 2 and 3). If turned on the
elements 5 to 10 will be enabled.
5 By default the device uses an optimized auto exposure algorithm, which also
works with back light conditions. If you want to manually setup the weighting of the
auto exposure, check this box and click the “Configure AEC Weights” button (see
point 6).
6 This button is only enabled, if the “Use Custom Weights” check box is checked
(see point 5). Click this button to open a dialog to setup the weights of the 5x5
measuring fields of the auto exposure control.
By default all fields are weighted equally with ‘1’, setting a higher value for one of
the fields prioritizes it, that means the AEC will try to correctly expose that field.
The minimum weight is 1, the maximum is 25.
7 The luminance set point defines how bright the auto exposure will set the output
image.
8 The maximum ISO setting defines how high the auto exposure is allowed to adjust
the sensor gain (see point 3). Use a lower value if you want to avoid noise in low
light scenarios, choose a higher value if more gain is needed and noise is of
secondary importance.
9 The control speed defines how fast the auto exposure reacts to changes in the
light conditions. A lower value means a faster reaction, but setting the value too
low might cause the controller to overshoot.
10 Set the anti flicker period to the power frequency of your country (e.g. 50 Hz in
Europe, 60 Hz in North America) to avoid screen flickering when the auto exposure
is enabled.
11 Enable lens shading correction. Please see the notes below this table for detailed
instructions on how to setup the lens shading correction module.
12 The Cosine
4
Compensation mainly adjusts the correction in the middle regions of
the image.
13 The Offset determines where the compensation of the outer image regions starts.
14 The slope defines how strong the compensation in the outer image regions is.
15 Set the video mode (resolution and timing).
