20110199465 | METHOD OF PROCESSING PARALLAX INFORMATION COMPRISED IN A SIGNAL - This invention relates to a method and a device of processing parallax information comprised in a signal. A signal comprising parallax map associated with further image information is received. A first data is obtained from the signal indicative of first parallax map constraints. A second data is obtained from the signal indicative of second parallax map constraints. Third data matching third parallax map constraints of a target device is determined by means of processing the at least the first data and the second data. This third data is used to generate an updated signal matching the parallax map information constraints of the target device. | 08-18-2011 |

20140168206 | DEPTH DEPENDENT FILTERING OF IMAGE SIGNAL - A method and apparatus for rendering of image data for a multi-view display, such as image data for a lenticular auto-stereoscopic display, is disclosed. The method comprises the steps of receiving an image signal representing a first image, the first image comprising 3D image data, and spatially filtering the first image signal to provide a second image signal. The second image signal represents a second image, the spatial filtering being, e.g., a low-pass filter, a high-pass filter or a combination of a low-pass and a high-pass filter. A strength of the spatial filter is determined by a reference depth of the first image and a depth of an image element of the first image. The second image is sampled to a plurality of sub-images, each sub-image being associated with a view direction of the image. | 06-19-2014 |

20110149037 | Method and system for encoding a 3D video signal, encoder for encoding a 3-D video signal, encoded 3D video signal, method and system for decoding a 3D video signal, decoder for decoding a 3D video signal. - In a method for encoding and an encoder for a 3D video signal, a principal data layer, a depth map for the principal data layers and further data layers are encoded. Several data layers are combined in one or more common data layers by moving data segments such as data blocks from data layers of origin into common data layers and keeping record of the shift in an additional data stream. | 06-23-2011 |
20110181588 | THREE DIMENSIONAL IMAGE DATA PROCESSING - Three dimensional image data is provided which includes data representing a first image which specifically may be a background image. A mixed image which is a combination of the first image and a second image which specifically may be a foreground image, a transparency map related to the mixed image comprising transparency values for pixels of the mixed image and a depth indication map for the mixed image comprising depth indication values for pixels of the mixed image. The use of a mixed image may allow three dimensional processing while at the same time allowing 2D backwards compatibility. Image quality around image objects may be improved by modifying transparency values in response to depth indication values and/or depth indication values in response to transparency values. Specifically, an improved alignment of transitions of depth indication values and transparency values may provide improved three dimensional foreground image object edge data. | 07-28-2011 |
20110199379 | METHOD AND DEVICE FOR PROVIDING A LAYERED DEPTH MODEL OF A SCENE - The invention relates to a device and method of providing a layered depth model of a scene, the layers of the depth model comprising primary view information for a primary view of the scene from a primary viewing direction and occlusion information associated with the primary view information for use in rendering in other views of the scene, wherein: the primary view information comprises layer segments of the model which are depth-wise closest with respect to the primary viewing direction, and the occlusion information comprises further layer segments of the model and wherein the occlusion in formation comprises a safety region (SR | 08-18-2011 |

20090315299 | Folding Stroller, Such as a Buggy, Comprising a Fixing Cross Bar System - The invention relates to a folding stroller such as a buggy having a seat. The frame of the stroller includes a pull/push rod; right and left front wheel rods, each provided with a front wheel; and a cross bar system provided between the front wheel rods. When the stroller is unfolded, the cross bar system fixes the distance between the wheel-carrying ends of the front wheel rods. The cross bar system is constructed such that when the stroller is folded, the distance between the wheel-carrying ends of the front wheel rods is less than when the stroller is unfolded. The cross bar system includes a right part, a left part and a middle part, which are provided with an interlocking member which, on rotation of the middle part, pushes the left and right parts apart and mutually fixes them. | 12-24-2009 |
