20090284538 | VIDEO STREAMING DATA PROCESSING METHOD - A video streaming data processing method is used in a video streaming data processing system including a central processing unit, a system memory, a graphic processing unit and a video random-access memory. After video streaming data are received, a video decoding operation is performed on the video streaming data by the central processing unit to produce image data and the image data are then stored into the system memory. Next, the image data are stored from the system memory to a texture buffer of the video random-access memory. Next, the image data that are stored in the texture buffer are read out and subject to a specific image processing algorithm by the graphic processing unit, and then stored back to the texture buffer. Afterwards, the image data are stored from the texture buffer to a video buffer of the video random-access memory. | 11-19-2009 |
20090284543 | COMPUTER AND METHOD FOR PROCESSING IMAGES - A computer having a CPU, a chipset and a graphic card is provided. The CPU is coupled to the graphic card through the chipset. The graphic card receives an output video from the chipset. The output video has a plurality of images, and each of the images has a plurality of pixels. The graphic card calculates the pixels of the image to obtain brightness values of the each pixels, and the brightness values are calculated to obtain brightness mapping values according to a non-linear function. Consequently, the graphic card is able to adjust a brightness contrast of each of the images so as to obtain a renewed output video. | 11-19-2009 |
