Patent number: 8284238Abstract: An image processing apparatus and a method for generating a three dimensional representation of a scene, which includes a plurality of objects disposed on a plane, is disclosed. The three dimensional representation is generated from one or more video images of the scene, which include the objects on the plane produced from a view of the scene by a video camera. The method includes processing the captured video images to extract image features from each object, comparing image features with sample image features from a predetermined set of possible example objects, and identifying the objects from the comparison of the image features with the sample image features. The method also includes generating object path data, which includes object identification data for each object which identifies the respective object; and provides a position of the object on the plane in the video images with respect to time.Type: GrantFiled: September 4, 2008Date of Patent: October 9, 2012Assignee: Sony CorporationInventors: Jonathan James Stone, Robert Mark Stefan Porter, Clive Henry Gillard

Patent number: 8086075Abstract: An image processing method for image conversion by combining two or more source values based on a mixing parameter to generate an output pixel value. A metric is calculated for a selected pixel at a given image field based on the directly preceding image field and a spatially interpolated version of the given image field at the selected pixel position. The selected pixel is categorized based on the metric as providing an indeterminate, unreliable, or reliable basis for a determination of motion at that pixel. The mixing parameter for the selected pixel is adjusted based on the categorization of the pixel.Type: GrantFiled: December 3, 2007Date of Patent: December 27, 2011Assignee: Sony United Kingdom LimitedInventors: James Edward Burns, Karl James Sharman, Nicholas Ian Saunders, Robert Mark Stefan Porter

Patent number: 8055094Abstract: An image processing apparatus includes a first motion detector, a second motion detector and a conversion selector. The first motion detector detects motion to a first level of spatial frequency sensitivity. The second motion detector detects motion to a second level of spatial frequency sensitivity greater than the first level of spatial frequency sensitivity to detect smaller amounts of motion than the first motion detector. The conversion selector selects contributions from at least one of a first conversion process and a second conversion process for a given point in an image dependant upon whether motion is detected by the first motion detector at the given point or not. The conversion selector operates independently of the second motion detector if a degree of motion within the image or a part thereof including the given point detected by the first motion detector does not exceed a threshold amount.Type: GrantFiled: December 3, 2007Date of Patent: November 8, 2011Assignee: Sony United Kingdom LimitedInventors: James Edward Burns, Karl James Sharman, Nicholas Ian Saunders, Robert Mark Stefan Porter
