Overview
Figure 2: Video processing unit
Fixed Pattern Noise (FPN) cancellation The FPN cancellation algorithm removes any column
variability over the video area.
Statistics gathering Image statistics are gathered on the full resolution input image and
forwarded to the camera control unit for exposure and color balance control loops.
Anti vignetting A radial gain is applied to the image luminance to compensate for possible
luminance loss in the corners of the image due to an imperfect lens system.
Defect correction The defect correction algorithm can detect and correct any defective pixels in a
sensor array.
Noise reduction filter The noise reduction filter is based on an adaptive algorithm. This algorithm
performs filtering but does not affect image areas including significant information.
Color interpolation Each pixel RGB components are calculated by interpolation of the incoming
Bayer pattern.
