Techniques of modifying image field data by extrapolation

摘要: Techniques for modifying data of an image that can be implemented in a digital camera, video capturing device and other optical systems are provided to correct Image shading variations appearing from two-dimensional photo-sensor. These caused by imperfect lenses, non-uniform sensitivity across the photo-sensor, internal reflections within housing system, example. In order these variations, small amount modification is stored memory camera or preferably separate correction each primary color. individual pixels corrected on fly interpolating pixel corrections data, at same rate as being acquired, so takes place without slowing down transfer picture sensor.
