Previously. we derived sensor optimal prefilters for image interpolation. The prefilters were applied prior to integer interpolation with a standard (e.g., linear or cubic) kernel. Here we expand upon that notion and construct complete, seiisor optimal interpolation kernels for rational interpolation factors. After restating the interpolation problem in a recpiisti uction-like fashion, we employ a simple model of the image capture system to derive the h4hISE interpolator. Results indicate
