Companding algorithm to transform an image to a lower bit resolution

Image Number 6 for United States Patent #6009206.

What is disclosed is a mapping circuit configured to map a range of captured intensity values to a companded intensity level based upon the density of captured intensity values present in the captured image. Also provided is a companding circuit coupled to the mapping circuit, the companding circuit configured to replace each pixel of the captured image with a corresponding mapped intensity value pixel. The companding circuit and mapping circuit are configured to preserve image characteristics.
