Zusammenfassung:A video correction system and method are disclosed that provide video correction for an input signal. The system includes a logarithmic converter that creates a logarithmic representation of the input signal. A configurable corrector/converter comprises a plurality of associated components operative to process the logarithmic representation of the input signal. The configurable corrector/converter produces an output signal having at least one desirable signal characteristic. A switch control selects a configuration for the corrector/converter. The configuration indicates at least one of the plurality of associated components that will process the logarithmic representation.
