Abstract

A method and apparatus are presented for processing a set of image data points representing an image and being detected by a detector array having array elements wherein each array element is responsive to only one of a first or a second color. The method includes the steps of generating a color test pattern; detecting actual output responses for at least one neighborhood of detector array elements corresponding to pixels in the color test pattern, where each neighborhood has a given array element responsive to the first color; measuring the response to the color test pattern of the second color of the given array element of each neighborhood of array elements, that is responsive to the first color, to determine the actual color content in the color test pattern that is responsible for the actual output response of the given array element; determining a set of weighting values which relate the actual color contents of the test pattern with the actual output responses to the test pattern; storing the set of weighting values; detecting actual output responses for a subject image for each neighborhood; and determining actual color contents, responsive to the second color for the given array element of each neighborhood corresponding to pixels in the subject image, which actual color contents of the subject image are related to the actual output responses of the subject image by the stored weighting values.
