20100271551 | Image Processing Apparatus and Image Processing Method - An image processing apparatus comprises an image decoding unit and a static noise reducing unit. The image decoding unit decodes a data stream and generates a plurality of image comprising a current image. The static noise reducing unit, coupled to the image decoding unit, generates a first adjustment value of a target pixel of the current image according to an original luminance value of the target pixel and at least one original luminance value of a neighboring pixel associated with the target pixel. The static noise reducing unit also determines a static adjustment luminance value of the target pixel according to the original luminance value, the first adjustment value, and a first weight. The first weight is associated with the chrominance value of the target pixel. | 10-28-2010 |

20100302449 | TV Image Adjusting Method and Apparatus Thereof - A television (TV) image adjusting method includes performing a variance calculation on luminance values of a plurality of pixels adjacent to target pixels of an image frame to generate a weight index; performing a decay function calculation according to the weight index to generate a weight distribution corresponding to the plurality of pixels adjacent to the target pixels. A function value of the decay function is inversely proportional to both the weight index and a target pixel distance between the target pixels and the plurality of pixels adjacent to the target pixels. The target pixel distance is a sum of vertical distances and horizontal distances between the target pixels and the plurality of pixels adjacent of the target pixels. The method further performs a weight calculation on the luminance values of the plurality of pixels adjacent to target pixels according to the weight distribution to generate an output luminance value. | 12-02-2010 |
