<p>An image data processing system comprises input circuitry for receiving the image data, an analyzing unit receiving the image data from the input circuitry and deducing image data compression parameters for dynamic range compression of the image data, a dynamic range compressor for receiving the image data from the input circuitry and the image data compression parameters from the analyzing unit and compressing the image data in correspondence with the image data compression parameters to provide dynamic range reduced image data and a further compressor for compressing the dynamic range reduced image data using a preselected image data compression parameter to provide output image data.</p> |
