    • A method of generating a depth map (122) comprising depth values representing distances to a viewer, for respective pixels of an image (100), is disclosed. The method comprises: segmenting the image into at least one group of pixels (104) corresponding to a foreground object and a further group of pixels (102) corresponding to background; assigning a first group of depth values corresponding to the further group of pixels (102) on basis of a predetermined background depth profile (110); assigning a second group of depth values corresponding to the at least one group of pixels (104) on basis of a predetermined foreground depth profile (110), whereby the assigning of the second group of depth values is based on a particular depth value of the background depth profile (110), the particular depth value belonging to a particular pixel (106) which is located at a predetermined location relative to the at least one group of pixels (104).
    • 公开了一种生成深度图(122)的方法,该深度图(122)包括表示对于图像(100)的各个像素的观看者的距离的深度值。 该方法包括:将图像分割为对应于前景对象的至少一组像素(104)和对应于背景的另一组像素(102); 基于预定的背景深度分布(110)来分配对应于另一组像素(102)的第一组深度值; 基于预定的前景深度分布(110)来分配对应于所述至少一组像素(104)的第二组深度值,由此所述第二组深度值的分配基于所述第二组深度值 背景深度分布(110),属于特定像素(106)的特定深度值,其位于相对于至少一组像素(104)的预定位置。

    • A 3D video conferencing station (200, 300, 500, 700) comprises: a camera (104) for acquiring a first (604) and second (602) image of a first user (110); and optical means for visualizing stereo images of a second user, the optical means comprising glasses for the first user (110). The station (200, 300, 500, 700) is arranged to acquire the first image (604) at a first moment at which the left eye of the first user (110) is better observable by the camera (104) than a second moment and to acquire the second image (602) at the second moment at which the right eye of the first user (110) is better observable by the camera (104) than at the first moment. The station further comprises combining means (714) for combining a first portion of the first image (604) and a second portion of the second image (602) into a third image (606) in which the left eye and the right eye of the first user (110) are relatively well visible.
    • 3D视频会议台(200,300,500,700)包括:用于获取第一用户(110)的第一(604)和第二(602)图像的相机(104); 以及用于可视化第二用户的立体图像的光学装置,所述光学装置包括用于第一用户(110)的眼镜。 所述站(200,300,500,700)被布置成在所述第一用户(110)的左眼比所述照相机(104)更好地观察到的第一时刻获取所述第一图像(604),而不是第二时刻 并且在第一时刻,第一用户(110)的右眼被照相机(104)更好地观察到的第二时刻获取第二图像(602)。 该站还包括用于将第一图像(604)的第一部分和第二图像(602)的第二部分组合成第三图像(606)的组合装置(714),其中左眼和右眼 第一用户(110)相对可见。
