Abstract: Embodiments of the present invention relate to a method and device operable to determine a duty cycle offset of a periodic signal and correct the periodic signal to a desired duty cycle. Embodiment of the present invention may include a ring oscillator circuit. The ring oscillator includes an odd number of ordered inverting elements. One or more of the inverting elements may be an inverting memory element. Each inverting element's output port (except the last inverting element) may be operably connected to the subsequent inverting element's input port. The last inverting element's output port may be operably connected to the first inverting element's input port, thereby forming a chain or ring. A counter may be incremented by oscillations of an output port of an inverting element during a high portion of a periodic signal and may be decremented by oscillations of the output port of the inverting element during a low portion of the periodic signal.

Abstract: An arbitration mechanism for balancing memory requests issued by parallel texture pipelines in a multiple pipeline texture engine. The mechanism ensures that, as polygon textures are processed by a texture engine, all of the memory requests associated with a portion of a given graphics texture are issued by all texture pipelines before any texture pipeline may issue a memory request for another portion of a graphics texture. Thus, the invention balances graphics texture processing between parallel texture pipelines operating together, thereby improving processing efficiency and preventing deadlock conditions.

Abstract: A method and apparatus to position photographed subjects so that the finished product has consistent artistic quality composition is disclosed. Photo templates will be generated implementing proven expert artistic photographic composition methods. The digital camera operator may choose the appropriate template to be displayed on the camera's view window as a superimposed overlay atop the image seen through the view lens. The operator should adjust the subject to mimic the chosen template. In the main embodiment of the invention, said photo template may be stored electronically or directly overlaid on the camera's view window. The composition information available by choosing the photo template can indicate to the camera the region of interest for exposing and focusing, thus eliminating the guesswork of the camera's computer. The primary purpose of the invention is to help the unskilled photographer to take better snapshots. The invention can also be used as a teaching aid in photography classes.
