ABSTRACT:
In some embodiments of the invention, when a color component (e.g. red, green or blue) is reconstructed at a pixel from the intensity values for this component at adjacent pixels, the intensities at the adjacent pixels are assigned weights. Greater weights are assigned to those pixels for which a gradient is smaller. The gradient for each adjacent pixel is indicative of a magnitude of a change of another color component in the direction of the adjacent pixel and/or a magnitude of the rate of change of the other color component in the direction of the adjacent pixel. In some embodiments, the weights are chosen to reduce the impact of noise. In some embodiments, the reconstructed value of a color component is adjusted to incorporate information on color spikes that is carried by another color component.
