Publication number: 20160366392Abstract: An image encoding method includes, for each of left and right images of an image stereo pair, identifying a region of interest (ROI) in an input image, generating multiple representations of that input image such that one representation is a high field of view (FOV) representation including substantially all of the input image and another representation is a low FOV representation having a lower FOV than the high FOV representation and including at least the ROI. The relationship between pixel resolution and image size for the high and low FOV representations is such that, in relation to the ROI, the low FOV representation provides more image detail than the high FOV representation. The method also includes generating one or more multiplexed images by juxtaposing portions of the left and right, high and low FOV representations so as to include all image content thereof in fewer than four multiplexed images.Type: ApplicationFiled: February 25, 2015Publication date: December 15, 2016Applicant: Sony Computer Entertainment Europe LimitedInventors: Sharwin Winesh Raghoebardajal, Ian Henry Bickerstaff

Publication number: 20160337630Abstract: Aspects of the technology encompass image encoding, which includes generating image content according to a viewpoint defined by image viewpoint data. Successive output images are generated such that each output image includes image content generated according to one or more viewpoints, and encoding metadata associated with each output image which indicates each viewpoint relating to image content contained in that output image, and which defines which portions of that output image were generated according to each of those viewpoints. An image display method for generating successive display images from successive input images is also provided, which includes re-projecting portions of each input image to form a respective display image, according to any differences between a desired display viewpoint and a particular viewpoint defined for that portion by metadata associated with a respective input image. The metadata indicating viewpoints relating to image content contained in the respective input images.Type: ApplicationFiled: February 25, 2015Publication date: November 17, 2016Applicant: Sony Computer Entertainment Europe LimitedInventors: Sharwin Winesh Raghoebardajal, Ian Henry Bickerstaff

Patent number: 9465436Abstract: A method of image reconstruction is provided. The method includes capturing a stereoscopic pair of images of a scene, generating a disparity map for the pair of images, and defining a series of value ranges corresponding to disparity with each value range in the series having an end point corresponding to a greater disparity than an end point of preceding value ranges in the series. For each value range in the series, and progressing in order through the series from the first value range in the series, the method includes selecting points in the disparity map falling within the respective value range and generating a mesh responsive to those selected points. The method also includes subsequently merging the series of generated meshes to form a 3D model of the scene.Type: GrantFiled: November 6, 2013Date of Patent: October 11, 2016Assignee: Sony Computer Entertainment Europe LimitedInventors: Sharwin Winesh Raghoebardayal, Simon Mark Benson, Ian Henry Bickerstaff

Publication number: 20160171704Abstract: A method generates an image for display by deriving an expected depth of field for the image and by generating the image for display by the display device by applying a blurring function. The expected depth of field is derived with respect to a point of focus in the image, in response to lighting conditions of the environment represented by the image. The blurring function is applied to simulate the expected depth of field of the image by blurring as a function of apparent spatial depth within the image. The degree of blurring applied to a closer depth region, in an apparent depth direction, to the point of focus is lower than the degree applied to a further depth region from the point of focus. Variation of the blurring function with respect to depth separation from the point of focus depends upon the expected depth of field.Type: ApplicationFiled: December 11, 2015Publication date: June 16, 2016Inventors: Sharwin Winesh Raghoebardajal, Ian Henry Bickerstaff

Publication number: 20160155231Abstract: A head mountable display (HMD) is provided that has an upward facing camera associated with a wide angle (such as a fisheye) lens arranged to capture images of the environment of the HMD. The HMD also includes an image comparator arranged to derive an indication of yaw of the HMD from images captured by the upward facing camera at different points in time. The image comparator may be configured to perform two or more detection techniques to detect HMD yaw, and to combine the results of the two or more detection techniques. The HMD may also include a tilt detector. Here, the image comparator may be configured to ignore one or more portions of a captured image in dependence upon a current tilt of the HMD as detected by the tilt detector.Type: ApplicationFiled: June 11, 2014Publication date: June 2, 2016Applicant: Sony Computer Entertainment Europe LimitedInventors: Sharwin Winesh Raghoebardajal, Ian Henry Bickerstaff

Patent number: 9310884Abstract: A head-mountable display system comprises a head mountable display having a frame to be mounted onto an observer's head, the frame defining one or two eye display positions which, in use, are positioned for viewing by the observer. The frame comprises one or more shutters for obscuring the observer's view of the surrounding real environment and a display element mounted with respect to each of the eye display positions. The display element provides a virtual image of a video display of a video signal from a video signal source to the observer. An object detector detects the presence of an object within a detection range of the observer's head. And a controller controls operation of the head mountable display so as to allow the observer to view at least a portion of the surrounding real environment in response to detection of the presence of an object within the detection range.Type: GrantFiled: May 3, 2013Date of Patent: April 12, 2016Assignee: Sony Computer Entertainment Europe LimitedInventors: Simon Mark Benson, Ian Henry Bickerstaff
