In a method for generating color image signals derived from an array of color image pixels, the array of color pixels are subsampled in order to generate an array of subsampled color pixels. An array of new, evenly spaced color pixels are interpolated from the subsampled color pixels using surrounding pixels of the same color, and the color image signals derived from the array of new color pixels are subsequently processed, e.g., in a color filter array interpolation. By providing this correction in a preprocessing step, the rest of the normal image processing hardware or software may be used on the resultant subsampled CFA image without developing the characteristic blocky and wavy artifacts caused by an irregular subsampling pattern.

1. A method for generating color image signals derived from an array of color image pixels, said method comprising the steps of:subsampling the array of color pixels in order to generate an array of subsampled color pixels, the pixels of the array of subsampled color pixels being unevenly spaced in a row direction and a column direction; interpolating an array of new, evenly spaced color pixels from the subsampled color pixels, the pixels of the array of new color pixels being evenly spaced in the row direction and the column direction, a given pixel of the array of new color pixels being interpolated using surrounding pixels, of the same color as the given pixel, in the array of subsampled color pixels; and processing the color image signals derived from the array of new color pixels.
