Patent number: 8027385Abstract: A method (1600) and apparatus (220) for encoding a sequence of images for transmission over a communication network is disclosed. Initially (1602) an object-based first image is rendered from a computer graphics application (240). The rendered first image is then (1604) encoded (226) according to a predetermined encoding scheme and transmitted (1606) for remote display (116). A test (1608) is then performed to determine if any more images are to be rendered. If so, the next (further) image is rendered (1612) from the computer graphics application (240). Changes between the first image and the further image are then determined (1614) from a change indicating output (244,246) of the computer graphics application (240). The identified changes are then used (1616) to determine a manner in which the further image is to be encoded according to the predetermined format. The further image is then encoded (1618) based upon the changes, and transmitted (1620) for remote display.Type: GrantFiled: July 19, 2006Date of Patent: September 27, 2011Assignee: Canon Kabushiki KaishaInventor: Zhenya Alexander Yourlo

Publication number: 20100079602Abstract: A method is described for positioning an image sensor at a point of best focus for a lens. The lens has an optical axis and the image sensor is moved to a plurality of positions along the optical axis. The image sensor captures an image of a target image at each of the plurality of positions through the lens. A measure of blur in the image captured is derived at each of the plurality of positions from pixel data output from the image sensor. A relationship is derived between blur and position of the image sensor along the optical axis. The image sensor is then moved to a position on the optical axis that the relationship indicates as the point of best focus where the image sensor is fixedly secured relative to the lens.Type: ApplicationFiled: September 24, 2009Publication date: April 1, 2010Inventors: Jonathon Leigh Napper, Zhenya Alexander Yourlo, Colin Andrew Porter, Matthew John Underwood, Robert John Brice, Zsolt Szarka-Kovacs, Paul Lapstun
