Abstract: A method of incorporating an augmented reality video image into a virtual environment comprises detecting a state of a real-world control object captured in a video image and augmenting the video image responsive to the state of the control object. The method further includes calculating trajectory parameters for an action with respect to a local coordinate system of the video image, responsive to the state of the control object, and embedding the augmented video image within a 3D virtual environment. The method also includes calculating the trajectory parameters for the action with respect to a local co-ordinate system of the 3D virtual environment, and rendering a graphical effect corresponding to the action within the 3D virtual environment.

Abstract: A method of augmented reality includes associating tint information with a predetermined graphical object, and receiving a video image of a real scene comprising a feature for detection. The method further includes detecting the feature in the video image of the real scene and selecting a graphical object responsive to the detected feature, and augmenting the video image with the selected graphical object. If the selected graphical object is the predetermined graphical object, the method further includes retrieving the tint information associated with the predetermined graphical object, and modifying the color balance of the video image responsive to the tint information.

Abstract: An entertainment device comprises an input, a marker detector and a failure boundary calculation processor. The input is operable to receive a captured image from a video camera. The marker detector is operable to detect a fiduciary marker within the captured image, and is also operable to estimate a distance and angle of the fiduciary marker. The failure boundary calculation processor is operable to calculate at least one of an additional distance and an additional angle from the currently estimated distance and angle of the fiduciary marker at which recognition of the fiduciary marker is assumed to fail.

Abstract: A method of image augmentation for an image of a book includes capturing an image of the book, detecting at least a portion of at least one fiduciary marker of the book within the image, estimating placement of the book's spine based upon the detected portion of the fiduciary marker, hypothesising possible positions for edges of a rigid leaf being turned in the book based upon estimated placement of the spine, processing the book image to identify edges within the image, comparing elements of the identified edges with the hypothesized positions for edges of the rigid leaf, selecting one of the hypothesized positions that best coincides with the compared elements of the processed image as representative of the position of the rigid leaf being turned in the book, and augmenting the book image with a virtual graphic element arranged in accordance with the selected representative position of the rigid leaf.
