Patent ID: 7826535

Claim:
Apparatus for processing data representing a first image compressed according to a first compression algorithm and a second image compressed according to a second compression algorithm, the first and second images each comprising pixels, the first compression algorithm being different from the second compression algorithm, the apparatus comprising: a processing module comprising first circuits arranged to process the data and second circuits arranged to process the data; a pixel analyzer arranged to select one of the first mode of filtering and the second mode of filtering according to first selection criterion and second selection criterion by performing the following: determining the frequency distribution values of the portion of the data using a first selection criterion; adding the frequency distribution values to generate a sum; and generating a mode selection signal in response to the sum and a second selection criterion; and a control processor arranged to enable at least a portion of the first circuits and disable at least a portion of the second circuits in response to a first selection signal in the event that the data represents the first image and to enable at least a portion of the second circuits and disable at least a portion of the first circuits in response to a second selection signal in the event that the data represents the second image, wherein the processing module receives one of the first selection signal or the second selection signal, and wherein the first selection criterion comprises a first register value equal to two and wherein the second selection criterion comprises a second register value equal to six.
