ABSTRACT:
A system for weighting nonlinear, e.g. logarithmic, pixel data as part of a missing pixel interpolation. This is accomplished to generate a weighted average of the logarithmic intensity values for those pixels which surround the missing pixel in order to approximate the logarithm of the linear average of these pixel values. Two weighting coefficients of unequal value are selected so that their sum equals the quantity one. The larger of the logarithmic values is weighted by multiplying the larger logarithmic pixel value by the larger weighting coefficient, and then by adding to this quantity the smaller logarithmic pixel value which has been multiplied by the smaller weighting coefficient. The result is a weighted logarithmic average which approximates the log of the linear average.
