Abstract
Color image decoding is achieved by a simplified method of decoding a spatially and chromatically multiplexing image plane (32), such as a plane consisting of RGB (Red-Green-Blue) pixels (22) by performing a summation of pixels of all three colors in a neighborhood of a missing pixel. The decoding process has applications in decoding images made by a data processor, made by an imaging device with a mosaic color filter, or made by a multi-sensor CCD imaging device with a sensor offset (800). Various techniques of entropy reduction, smoothing and speckle reduction may be incorporated into the coefficient pattern. The coefficient pattern may be generated automatically using a process of correlated decoding and may be adjusted by hand using a process of trial and error.
