  • Patent number: 9595128
    Abstract: 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.

  • Patent number: 9185432
    Abstract: In a method for encoding a 3D signal comprising layered-depth images, the viewing area of further layers are (background layers) made to differ in size and/or shape from the viewing area of a reference view (foreground layers) and the 3D image signal is provided this with appropriate scaling data expressing the relation between the reference view viewing area and the one or more further layer's viewing area.

  • Patent number: 9036006
    Abstract: The invention relates to a system and method of processing an input three dimensional video signal comprising multiple views, the method comprising: determining a far disparity estimate indicative of the largest disparity value for the input three dimensional video signal, a near disparity estimate indicative of the smallest disparity value for a spatial region within the input three dimensional video signal, adapting the input three dimensional video signal by shifting the input three dimensional video signal backwards by means of a disparity shift based on the far disparity estimate and generating an overlay within the spatial region for the shifted three dimensional video signal based on the near disparity estimate and the disparity shift. The invention further relates to a computer program product implementing a method according to the present invention.

  • Patent number: 8913108
    Abstract: 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.

  • Patent number: 8447141
    Abstract: The present invention relates to a device and method (100) of generating a depth map for an image using monocular information, the method comprising: generating (110) a first depth map for the image (205), wherein the first depth map corresponds with an estimate of a global depth profile of a scene depicted in the image, generating (120) a second depth map for the image, wherein a depth value associated with a pixel in the second depth map is based on depth values in the first depth map within a region spatially proximate to the pixel and at least one of color and luminance values of the image within the region and generating (130) a third depth map for the image using depth values from the first depth map and the second depth map, the generating scaling a depth difference, such that a difference between a depth value of the third and first depth map is scaled compared to the corresponding difference between a depth value of the second and first depth map.
