摘要： An image capture system includes a sparsely sampled extended dynamic range image sensing device having fast photosites interspersed with slow photosites for producing a sparsely sampled high resolution digital image having fast pixel values produced by the fast photosites and slow pixel values produced by the slow photosites. A processor employs the slow pixel values to expand the dynamic range of the fast pixel values in the sparsely sample high resolution digital image to form a full resolution digital image having an extended dynamic range. A color encoder reduces the dynamic range of the full resolution digital image to fit within the dynamic range of a storage color space having a dynamic range less than that of the full resolution digital image to form a limited dynamic range digital image represented in the storage color space.

摘要： A method for processing an extended color gamut digital image so as to represent the extended color gamut digital image in a storage color space having a limited color gamut digital image and for paying for such processed digital image including a user sending or authorizing the sending of an extended color gamut digital image to a processing site where the extended color gamut digital image is to be processed. Processing such extended color gamut digital image at the processing site can be accomplished by adjusting the color values of the extended color gamut digital image to fit within the limited color gamut to form a limited color gamut digital image, and representing the limited color gamut digital image in the storage color space. Further, by determining one of more residual images representing differences between the extended color gamut digital image and the limited color gamut digital image, and associating the one of or more residual image(s) with the limited color gamut digital image in the storage color space such that the associated residual image(s) and the limited color gamut digital image are adapted to be used to form a reconstructed extended color gamut digital image. The method also includes the user making payment, and making the processed extended color gamut digital image available to the user via a communications network.
