Dark level compensation
A dedicated DSP uses information from special dark lines within the pixel array to apply an
offset to the video data and ensure a consistent ‘black’ level.
Flicker cancellation
The 50/60 Hz flicker frequency present in the lighting (due to fluorescent lighting) can be
cancelled by the system.
Statistics
The function of the statistics processor is to gather statistics on Bayer IDP data. The
statistics are made available to the Imaging Control Bus Host for tasks such as automatic
exposure control and white balance.
Lens shading correction
The lens shading correction module is used to reduce the visible effect of vignetting where
inherent problems in lens design can cause non-uniformities in levels of light transmission
across the image plane. The extent of transmission loss is primarily a function of lens quality
and fabrication tolerances, but generally increases radially from the lens’ optical centre
towards the edges of the scene.
