More Information
Summary:A noise eliminating device may include a noise eliminating mechanism which eliminates an isolated noise in an image being photographed. The noise eliminating mechanism may include a noise pixel detection mechanism and a pixel correction mechanism. The noise pixel detection mechanism may detect a noise pixel by scanning the image. The pixel correction mechanism may correct a level of a detected noise pixel based on a level of a pixel located in a predetermined area from the noise pixel. A noise eliminating method for eliminating an isolated noise in an image being photographed may include the steps of detecting a noise pixel by scanning the image and correcting a level of the detected noise pixel based on a level of a pixel located in a predetermined area from the noise pixel.
