Per-pixel estimating and color correction of photodetector array

摘要

A correction method of systematic error of observations of color coordinates of a photosensor array allowing correcting and estimating the colors of each pixel in the image is proposed. The estimates of color coordinates of uniform color are calculated according to the results of observation of the colors of individual pixels based on the covariance matrix of the observation errors and model of dependence of the observed color coordinates on genuine ones.
