Abstract: Disclosed is an automatic white balance method for image capturing apparatus. An image capturing apparatus captures a color image first and performs gray point searching in RGB color space or YUV color space. The color correction coefficient sets of red color, green color and blue color components of each gray points are computed respectively, and then the color correction coefficient sets of all the gray points are averaged to generate a color correction average value set. Each pixel of the color image is color-corrected in a color space according to the color correction average value set so as to obtain an optimum white balance effect. The present invention is beneficial for the reduction of design cost, downsizing of storage memory space, decrease of computation quantity and simplification of image-searching process.

Abstract: A method of function execution to reduce memory usage in a wireless system. An image is processed in blocks rather than a complete image. Multiple functions are executed for the same block. When all the functions have been executed for a particular block, the next block is processed. This is repeated until all functions have been executed for all blocks. Programming is achieved by first programming parameters for each function. Then each function is defined in a recursive command after which the recursive command is fired for execution and all functions are automatically executed. The system comprises a base band with an application processor, a media processor with a command manager and function units, and an LCD module with a panel and a frame buffer. The method significantly reduces the amount of memory required which not only lowers cost but also greatly simplifies the system.

Abstract: An input/output register programming system that uses a set transmission value. The input/output register programming system includes an address decoder, a transmission setting register, a partitioning device, an internal address generator and a transmission space. The address decoder decodes the write address to determine the type of input command. If the input command is a transmission setting register write command, the input data is written down to be used as a set transmission value. The set transmission value determines the target region address of the input command. If the input command is an input/output register write command, the target region address is output. The partitioning device divides the input data into a secondary address and stored data. The internal address generator combines the secondary address with the target region address to produce an internal address. The stored data are transmitted to the registers specified by the internal address.

Abstract: The present invention proposes a multimedia-instruction acceleration device and a method thereof, which uses instruction strings having a floating-point value check field to execute commands of single-instruction/multi-data format. The present invention can effectively save executing time and simplify numerical calculation process, and can fully exploit memory space to achieve the object of increasing acceleration operation and execution of 3D multimedia instructions. Moreover, an instruction of another mode can be added among the multi-data pertaining to a single 3D instruction so that another program such as a voice-playing program can be executed during the process of 3D acceleration operation. The performance of the multimedia program can thus be enhanced.
