    • A method of rendering an output image (202) on basis of an input image (200) and a corresponding matrix of depth related data (204), the input image (200) corresponding to a first viewpoint and the output image (202) corresponding to a second viewpoint being different from the first viewpoint, is disclosed. The method comprises: computing edges (212,312) in the matrix of depth related data (204), by computing derivatives of the depth related data in a predetermined direction (X); computing a measure of variation in pixel values in regions of the input image (200) corresponding to neighborhoods of the edges (212,312), the neighborhoods located at the background side of the edges (212,312); and computing the output image (202) by shifting respective pixel values of the input image (200) in the predetermined direction (X) on basis of scaled depth related data, wherein scaling is such that a relative large measure of variation results in a relative large reduction of depth.

    • A new method of encoding multiple view image information into an image signal (200) is described, comprising: adding to the image signal (200) a first image (220) of pixel values representing one or more objects (110, 112) captured by a first camera (101); - adding to the image signal (200) a map (222) comprising for respective sets of pixels of the first image (220) respective values, representing a three-dimensional position in space of a region of the one or more objects (110, 112) represented by the respective set of pixels; and adding to the image signal (200) a partial representation (223) of a second image (224) of pixel values representing one or more objects (110, 112) captured by a second camera (102), the partial representation (223) comprising at least information of the majority of the pixels representing regions of the one or more objects (110, 112) not visible to the first camera (101). Advantages are less required information for higher precision and increased usability.

    • A device for reproducing video data signals receives encoded video data signals; and has a processing unit for decoding the encoded video data signals into the video data signals. The encoded video data signals comprises a base stream of signals (801) representing a standard resolution portion of the video data signals and at least one enhancement stream of signals (802) representing a high-resolution portion of the video data signals. The processing unit has a detection unit for detecting a predefined interlacing mode for the base stream of signals, e.g. non-interlaced or specifically interlaced, and adapting the decoding to decode the base stream of signals in dependence of said detected predefined interlacing mode. Advantageously, the decoding may include vertical filtering to reduce line flicker in re-interlaced video based on the detected non- interlace encoded video signals, or may include reshuffling of encoded video signals based on shuffled video for reducing motion judder in re-interlaced video.
    • 用于再现视频数据信号的装置接收编码的视频数据信号; 并且具有用于将编码的视频数据信号解码为视频数据信号的处理单元。 编码的视频数据信号包括表示视频数据信号的标准分辨率部分的信号(801)的基本流和表示视频数据信号的高分辨率部分的至少一个增强信号流(802)。 处理单元具有用于检测基本信号流的预定隔行模式的检测单元,例如, 非隔行扫描或特别隔行扫描,并根据检测到的预定交织模式使解码器解码基本信号流。 有利地,解码可以包括垂直滤波以基于检测到的非隔行编码视频信号来减少重隔行视频中的线闪烁,或者可以包括基于混洗视频的编码视频信号的重新排列,以减少重隔行视频中的运动抖动。
