| 20120027319 | METHOD AND ELECTRONIC DEVICE FOR REDUCING DIGITAL IMAGE NOISES - A method and an electronic device for reducing digital image noises are described. The method includes the steps of sequentially selecting a pixel from a digital image, and setting the pixel as a target pixel; defining a first area, and setting at least two of the rest pixels surrounding the target pixel in the first area as adjacent pixels; setting a first weighted area; setting a second weighted area corresponding to the first weighted area; computing a weight of the adjacent pixel located at a center position of the second weighted area by using a piecewise linear curve according to a similarity value of the first weighted area and the second weighted area; computing a weighted average of all the adjacent pixels and the target pixel, to determine a new value of the target pixel; and performing the above steps repeatedly, till all the pixels are processed. | 02-02-2012 |
| 20110235715 | VIDEO CODING SYSTEM AND CIRCUIT EMPHASIZING VISUAL PERCEPTION - A video coding system and circuit emphasizing visual perception are presented, which mainly include a video coding module and a video analysis module. A video frame is respectively input into the video coding module and the video analysis module. The video coding module performs a coding process on the input video frame, the video analysis module analyzes the input video frame to generate a quantization parameter adjustment value, and then the video coding module adjusts each coding parameter with the quantization parameter adjustment value. In this manner, a more efficient compression can be performed on the video frame, and the compressed video frame still maintains good image quality. | 09-29-2011 |
