A color resolution enhancement method and enhanced color cameras (600) with a single CCD detector (606) having attached color filters (604) and using luminance-based gradient interpolation to fill in color channels. A color camera, includes an image detector, the detector with sets S1, S2, . . . SN of pixels for N, an integer greater than 1, where pixels in the set SJ detect radiation in a corresponding sampled channel CJ for each J in the range 1 to N, a channel reconstructor coupled to an output of the detector. The reconstructor includes a luminance generator which combines the sampled channels C1, C2, . . . CN to a luminance channel, a gradient generator coupled to an output of the luminance generator and which transfers the luminance channel to a gradient channel, and a directional interpolator coupled to an output of the detector and to an output of the gradient generator and which transfers each of the sampled channels C1, C2, . . . CN to a corresponding reconstructed channel RC1, RC2, . . . RCN, and a reconstructed channel output.
