APPARATUS AND METHOD FOR GENERATING AN IMAGE
First Claim
1. An apparatus for generating an image, the apparatus comprising:
- a first receiver circuit, the first receiver circuit arranged to receive a 3D image data of a scene, wherein the 3D image data provides an incomplete representation of the scene in that the 3D image data does not provide a description of the visual properties for at least one part of the scene for at least one viewpoint;
a view vector source, the view vector source arranged to provide a rendering view vector indicative of a first viewpoint in the scene;
a renderer circuit, the renderer circuit arranged to render a first region of a first image based on the 3D image data,wherein the first image is for the first viewpoint indicated by the rendering view vector,wherein the 3D image data comprises image data for the first region;
an extrapolator circuit, the extrapolator circuit arranged to extrapolate the 3D image data into a second region of the first image, wherein the 3D image data does not comprise image data for the second region and the first region and the second region are adjoining regions; and
a blur processor circuit, wherein the blur processor circuit generates the image,wherein generating the image comprises applying a spatially varying blurring to the first image,wherein a degree of blurring is higher in a transitional region between the first region and the second region than for an internal area of the first region.

Abstract
An apparatus for generating an image comprises a receiver (101) which receives 3D image data providing an incomplete representation of a scene. A view vector source (103) provides a rendering view vector indicative of a rendering viewpoint for the image. A renderer (105) renders a first region of an intermediate image for the rendering view vector based on image data from the 3D image data. An extrapolator (107) extrapolates the 3D image data into a second adjoining region of the intermediate image with the 3D image not comprising image data for the second region. A blur processor (109) generates the image in response to applying a spatially varying blurring to the intermediate image where a degree of blurring is higher in a transitional region between the first region and the second region than in an internal area of the first region.

14. A method of generating an image, the method comprising:
-
receiving a 3D image data for a scene, wherein the 3D image data provides an incomplete representation of the scene in that the 3D image data does not provide a description of the visual properties for at least one part of the scene for at least one viewpoint; providing a rendering view vector indicative of a first viewpoint in the scene; rendering a first region of a first image based on the 3D image data, wherein the first image is for the first viewpoint indicated by the rendering view vector, wherein the 3D image data comprising image data for the first region; extrapolating the 3D image data into a second region of the first image, wherein the 3D image data does not comprise image data for the second region and the first and second regions are adjoining regions; and generating the image, wherein generating the image comprises applying a spatially varying blurring to the first image, wherein a degree of blurring is higher in a transitional region between the first region and the second region than for an internal area of the first region.
