ABSTRACT:
A number of multiple-band pixels are stored in a number of data words and the multiple-band pixels are merged and sorted such that all components of each band of the pixels are stored contiguously and in the order in which the multiple-band pixels are originally stored in the data words. As a result, the pixels are converted from an interleaved format to a planar format. The data words are essentially divided in half and the halves are merged such that the pixel components are interleaved in a number of intermediate data words. By repeatedly dividing the intermediate data words in half and merging the respective halves, the components of all the pixels corresponding to each band are stored contiguously in a number of data words. The contiguous components of each band are sorted such that the components of each band are stored in the order in which the multiple-band pixels are originally stored in the data words. For example, the contiguous components can be sorted using the same merge operation used to sift the components of the respective bands into contiguous storage locations.
