Part 2: Components and Implementation        Part 3: Photographic Conditions for Example Images
 

Color aliasing persists as a difficult problem in digital imaging. The first image here shows this problem, which can occur whenever an image is sharply focused onto a sensor that samples different colors at different points. (Part 3 describes how this image and the following one were produced.) We offer a novel and proprietary optical filtering technology that eliminates these aliasing artifacts. The second image demonstrates the application of our technology. Our filter works by an entirely different principle from that of standard birefringent antialiasing filters, and it offers significant advantages over conventional strategies: The filter does not blur or defocus images, which therefore retain all of their original sharpness. Conventional antialiasing filters prevent color artifacts through blurring or spatial lowpass filtering, but this permanently destroys fine detail.   As the images show, small details retain their original color with this approach. Software postprocessing approaches to aliasing correction typically reduce small colored regions to shades of gray.   No complex processing algorithms are involved. Color interpolation can be implemented in simple hardware at extremely high speeds, making this approach well suited to live video applications such as cinematography.
