Patent number: 8509521Abstract: A method of generating a three dimensional image from a two dimensional image having a background and a first foreground object and a second foreground object. The method includes determining whether the first and second foreground objects occlude, and generating an occluded combination of the first and second object to form a third foreground object when occlusion occurs. The method further includes applying a transformation to the third foreground object, and generating a copy of the third foreground object with the transformation applied thereto. Then, the third foreground object is generated stereoscopically for display based on the transformed third foreground object displaced relative to the copy of the third foreground object.Type: GrantFiled: August 20, 2010Date of Patent: August 13, 2013Assignee: Sony CorporationInventors: Stephen Mark Keating, Clive Henry Gillard

Publication number: 20100226425Abstract: An encoding data processor generates a video material item marked copy by representing a payload data word as a code word and embedding the code word into a copy of the video material item. A preprocessor divides the payload word into plural parts, forms plural initial values from the plural parts, each initial value formed by adding parts of the payload data word to each initial value successively starting with the first part added to the first initial value, and adds the first and second to the second initial value so each subsequent initial value includes all parts of the payload data word of the previous initial values and a new part of the payload data word. An encryption processor receives each initial value and generates an encrypted data stream using a payload encryption key. A combiner combines the encrypted payload data word with the video material item.Type: ApplicationFiled: May 3, 2007Publication date: September 9, 2010Applicant: SONY UNITED KINGDOM LIMITEDInventors: Stephen Mark Keating, Ian McLean, Mark Julian Russell, Daniel Luke Hooper, Daniel Warren Tapson
