Film-like images with super-fine details using Foveon X3 Technology

Abstract

With its three vertically stacked photodiodes, the Foveon X3 image sensor enables direct captures of red, green and blue light at each pixel in an image during a single exposure. It greatly reduces computational time for interpolation for missing colors in conventional Bayer sensors and therefore color aliasing. Meanwhile, with the new Super-Fine Detail (SFD) exposure mode, cameras equipped with Foveon X3 technology can capture as many as 51 megapixel-equivalent noiseless images with an extensive dynamic range.
