20080303894 | Stereoscopic Image Display Method and Apparatus, Method for Generating 3D Image Data From a 2D Image Data Input and an Apparatus for Generating 3D Image Data From a 2D Image Data Input - 2D image data are converted into 3D image data. The image is divided, on the basis of focusing characteristics, into two or more regions, it is determined to which region an edge separating two regions belongs. The regions are depth ordered in accordance with the rule that the rule that a region comprising an edge is closer to the viewer than an adjacent region and to the regions 3-D depth information is assigned in accordance with the established depth order of the regions. Preferably to each of the regions a depth is assigned in dependence on an average or median focusing characteristic of the region. | 12-11-2008 |
20090073170 | DISPARITY MAP - A method of computing an output disparity map, comprising output elements having output values corresponding to shifts to be applied to respective pixels of a first image to compute a second image is disclosed. The computing is on basis of an input disparity map comprising respective input elements having input values. The method comprises: determining a particular input value ( | 03-19-2009 |
20090153652 | DEPTH DEPENDENT FILTERING OF IMAGE SIGNAL - The invention pertains to rendering of image data for a multi-view display, such as image data for a lenticular auto-stereoscopic display. The method comprising the steps of receiving an image signal representing a first image, the first image comprising 3D image data, spatially filtering the first image signal to provide a second image signal, the second image signal representing a second image, the spatial filtering being such as 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, and sample the second image to a plurality of sub-images, each sub-image being associated with a view direction of the image. | 06-18-2009 |
20090267958 | IMAGE VIEWING USING MULTIPLE INDIVIDUAL SETTINGS - A method of displaying an image having at least two different image settings comprises the steps of providing at least three different partial images, and displaying the at least three partial images. A first and second pair of partial images constitute the image having a first image setting and the same image having a second image setting respectively, such that the image having both image settings is visible. The partial images may be displayed either simultaneously or consecutively. The settings may comprise contrast, brightness and/or depth settings. | 10-29-2009 |
20100220920 | METHOD, APPARATUS AND SYSTEM FOR PROCESSING DEPTH-RELATED INFORMATION - The invention relates to a method, apparatus and system for processing first depth-related information associated with an image sequence. The method of processing comprises mapping first depth-related information of respective images of a shot of the image sequence on corresponding second depth-related information using a first estimate of a characteristic of the distribution of first depth-related information associated with at least one image from the shot, the mapping adapting the first depth-related information by enhancing the dynamic range of a range of interest of first depth-related information defined at least in part by the first estimate, and the amount of variation in the mapping for respective images in temporal proximity in the shot being limited. | 09-02-2010 |

20110123113 | USE OF INPAINTING TECHNIQUES FOR IMAGE CORRECTION - A method of processing an image signal comprising image and depth information is provided. The method is configured to perform segmentation on an image based on depth/disparity information present in the image signal comprising said image, and subsequently inpaint background for correction of the errors in the image around the foreground objects into a region that extends beyond the segment boundary of the foreground object and/or inpaint foreground for correction of errors in the image into a region that extends inside the segment boundary of the foreground object. In this way compression and other artifacts may be reduced. | 05-26-2011 |
20110255159 | AUTOSTEREOSCOPIC DISPLAY DEVICE - There is disclosed a multi-view autostereoscopic display device comprising an image forming means arranged over and in registration with a view forming module. The image forming means has a planar array of light emissive display pixels arranged in rows and columns for producing a display, the display pixels being spatially defined by an opaque matrix. The image forming means may, for example, be a LCD display panel. The view forming module is configurable to function as a plurality of view forming elements arranged in the width direction of the display device, each view forming element focusing the light output from an adjacent group of the display pixels into a plurality of views for projection towards a user in respective different directions. The view forming module may, for example, be an array of lenticular lenses. The geometry of the view forming elements defines a substantially periodic inter-element variation in the width direction of the display device, for reducing brightness non-uniformities in the views. The inter-element variation may, for example, be provided by varying at least one of the widths, the focusing powers and the relative positions of the geometric axes of the lenticular lenses in the width direction of the display device. | 10-20-2011 |
