Abstract: Creating a blur in a digital image by receiving original pixel values in a frame of image data, and for each pixel position in the digital image being blurred, calculating a blurred pixel value by applying a box filter having a plurality of elements with unity multiplier values to original pixel values for pixel positions that include the pixel position and pixel positions that are nearby to it. The output of the first box filter can be sequentially applied as inputs to a second box filter.

Abstract: The invention provides a method for transforming pixels of a digital image by a preselected-transformation. The method includes acts for receiving pixel values of a selected pixel block from an original image provider; determining transformed pixel values for an image block of the selected pixel block under the transformation; and burst writing the transformed pixel values to a random access memory.

Abstract: Combining first and second video streams into a combined output video stream by using a gradient table listing gradient values for pixels in a video frame to address a look up table of key values, and combining pixel values of the first and second video streams based upon respective key values read from the look up table.

Abstract: A method of assigning priorities and resolving bus contention in a distributed computer system is disclosed. Each system node is assigned an identifier. Priorities are reassigned at each change in bus access such that the node that most recently had access to the bus is assigned the lowest priority with the node having the next identifier in sequence being assigned the highest priority and all other nodes assigned priority in accordance with their identifier's position in the sequence. The identifiers are logically treated as organized in a circular fashion such that the lowest node identifier is considered to come next in the sequence after the highest node identifier.
