  • Patent number: 8441579
    Abstract: In a device for processing baseband signal images (BS), a film detector determines whether a same baseband signal image includes both information from a film image and information from a video source image, information from one film image being present in at least two baseband signal images while information from one video source image is present in only one baseband signal image. A processing unit processing the baseband signal images in such a manner that in the presence of both information from the film image and information from the video source image in the same baseband signal image, for each film image only one of the at least two baseband signal images is used to obtain a display signal image (DS).
    Type: Grant

  • Patent number: 7382899
    Abstract: A segmentation system (100) for segmenting a first image feature (214) in a first video image from an adjacent second image feature (216) in the first video image on basis of motion and on an image property like color or luminance. The segmentation system (100) comprises; a block-based motion estimator (102) for estimating motion vectors (218-230) for blocks of pixels; a motion segmentation unit (104) for segmenting the first video image into a first group of connected blocks of pixels (204) and a second group of connected blocks of pixels (206) on basis of the motion vectors (218-230) of the respective blocks of pixels; and a pixel-based segmentation unit (106) for segmenting the first image feature (214) from the second image feature (214) by means of a pixel-based segmentation of a portion of the blocks of pixels of the first and second group of connected blocks of pixels (214 and 216), on basis of the respective values of the image property.
