Embodiment Construction

[0032] In simple optical systems such as thin convex lenses, objects at a certain distance from the lens are clearly presented on the image plane (objects are in focus), while objects at other distances are proportional to their distance from the plane of focus Ground blur mapping (objects are defocused). exist figure 1 The latter case of point lights is described in .

[0033] The blur performance is based on the thin lens formula:

[0034] 1 f = 1 u + 1 v - - - ( 1 )

[0035] where f represents the focal length of the lens, u is the object distance and v is the image distance. according to figure 1 The geometric relationship and lens formula in , the formula for the distance u can be derived:

[0036] u = fs ...

Abstract

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.

Description

technical field [0001] The present invention relates to a stereoscopic image display method, wherein 2D image data is converted into 3D image data, wherein focus information is extracted from the 2D image data, the focus information being used to generate the 3D image data. [0002] The present invention also relates to a stereoscopic image display device comprising an input for 2D image data, and a converter for converting the input 2D image data into 3D image data, the converter comprising a focus information extractor for extracting information from the 2D image Data extraction focuses on information. [0003] The present invention also relates to an image display data conversion method, wherein 2D image data is converted into 3D image data, and wherein focus information is extracted from the 2D image data and used to generate the 3D image data. [0004] The invention also relates to 3D image signals. [0005] The invention also relates to a computer program product compr...
