摘要： An image conversion unit (400,700) for converting an input image with an input aspect ratio into an output image with an output aspect ratio being different from the input aspect ratio, is disclosed. The image conversion unit (400,700) comprises segmentation means (402) for segmentation of the input image on basis of pixel values of the input image, resulting in a first group of connected pixels forming a first input segment (310) which represents a first object and a second group of connected pixels forming a second input segment (306) which represents a second object; and scaling means (404) for scaling the first input segment (310) in a first direction with a location dependent scaling factor into a first output segment (320) of the output image and for scaling the second input segment (306) in the first direction with a constant scaling factor into a second output segment (316) of the output image.

摘要： The invention provides a method for visualisation of a 3-dimensional (3-D) scene model of a 3-D image, with a 3-D display plane comprising 3-D pixels by emitting and/or transmitting light into certain directions by said 3-D pixels, thus visualising 3-D scene points. The calculation of the 3-D image is provided such that said 3-D scene model is converted into a plurality of 3-D scene points, said 3-D scene points are fed at least partially to at least one of said 3-D pixels, said at least one 3-D pixel calculates its contribution to the visualisation of a 3-D scene point.

摘要： A mirror assembly (18) for displaying an image (15) in conjunction with the reflection (14´) of a viewer comprises a mirror (2), which is equipped with a reflective polariser (13), arranged to reflect light (3) incident on its viewing side and transmit light (4) incident on its non-viewing side, where the reflected light (3) and transmitted light (4) may be of different polarisation. The image (15) is displayed by a device (5) located on the non-viewing side and focussed by a focussing element, e.g. one or more lenses (12, 12a), onto an image plane. The image plane may be located between the mirror (2) and viewer (14), so that a perceived image (15´) appears to stand out from the mirror (2). Alternatively, the image plane may be located so that the perceived image (15´) forms a background in which the viewer's reflection (14´) is immersed. The mirror assembly (1) may further comprise one or more detectors (19) for obtaining a silhouette (21) of the viewer (14). The silhouette (21) can be subtracted from an image (15) to produce a modified image (24) for display by device (5), thereby avoiding competition between the perceived image (15´) and viewer reflection (14´).

摘要： A handheld device (1) has a display screen (2, 22), and means for displaying a document on the screen and means for scrolling through the document by tilting the device. The device comprises a splitting screen (23, 24, 61, 71) in front of the display screen (22) for splitting the image in a number of sub-images in a number of viewing zones (A,B,C,D), and in operation for each or for each or for a number of viewing zones a different part of a document is visible in a manner such that when tilting the device the parts of the document are visible in a sequential manner. The device may be tilted around a horizontal or vertical axis depending on the orientation of the splitting screen.

摘要： A method and apparatus for providing spatial scalable compression of a video stream is disclosed. The video stream is downsampled to reduce the resolution of the video stream. The downsampled video stream is encoded to produce a base stream. The base stream is decoded and upconverted to produce a reconstructed video stream. The reconstructed video stream is subtracted from the video stream to produce a residual stream. It is then determined which segments or pixels in each frame have a predetermined chance of having a predetermined characteristic. A gain value for the content of each segment or pixel is calculated, wherein the gain for pixels which have the predetermined chance of having the predetermined characteristic is biased toward 1 and the gain for other pixels is biased toward 0. The residual stream is multiplied by the gain values so as to remove bits from the residual stream which do not correspond to the predetermined characteristic. The resulting residual stream is encoded and outputted as an enhancement stream.
摘要翻译：公开了一种用于提供视频流的空间可缩放压缩的方法和装置。视频流被下采样以降低视频流的分辨率。下采样的视频流被编码以产生基本流。基本流被解码和上变频以产生重建的视频流。从视频流中减去重建的视频流以产生残余流。然后确定每个帧中的哪些段或像素具有预定的具有预定特性的机会。计算每个段或像素的内容的增益值，其中具有预定特征的预定机会的像素的增益被偏向1，并且将其他像素的增益偏向0.将剩余流乘以增益值，以便从不符合预定特性的剩余流中除去比特。所得到的残留流被编码并作为增强流输出。

摘要： A 3D video conferencing station (100) comprises a video camera (102) for capturing video signals and a depth map calculator (104) for creating a depth map (120) of a user (114) of the 3D video conferencing station (100). Thevideo signals together with the depth map are transmitted as 3D video data. The 3D video conferencing station (100) further comprises a stereoscopic display device (112) for displaying stereo images, which are calculated on the basis of received 3D video data. The depth map which is generated by the depth map calculator (104) is also used for estimating the position of the user (114) in order to control the calculation of the stereo images.
