Abstract

An image processing system and method, in which an analysis is performed on received pixels to determine whether those pixels exhibit characteristics matching a pre-defined source type. If such a match is found, a corresponding preconfiguration is applied to one or more image processing operations.

Claims

1. A method of processing a video signal, comprising:

receiving pixels forming a portion the video signal;

determining whether the video signal has characteristics that match any of a plurality of pre-defined source types, where each of the pre-defined source types has an associated preconfiguration that specifies initial settings for one or more of a plurality of image processing operations to be applied to the video signal;

if the video signal does have characteristics that match one of the pre-defined source types, selecting and applying the preconfiguration associated with the one of the predefined source types; and

After selecting and applying one of the preconfigurations, dynamically modifying the initial settings for the one or more of the image processing operations during processing of the video signal.

2. A method of processing a video signal, comprising:

receiving pixels forming a portion the video signal;

performing an initial classification analysis on the pixels to determine whether the video signal has characteristics that match any of a plurality of pre-defined source types, where each of the pre-defined source types has an associated preconfiguration that specifies initial settings for one or more of a plurality of image processing operations to be applied to the video signal; and

if the video signal does have characteristics that match one of the pre-defined source types, selecting and applying the preconfiguration associated with the one of the predefined source types.
