Embodiment Construction

[0034] Embodiments of the present invention operate on three-dimensional (3D) television signals. This embodiment is generally independent of the signal source. That is, the device is operable to generate a qualitative assessment of the 3D television signal (regardless of origin) provided to the device. This could be a direct feed from a 3D camera device, a computer generated or computer enhanced 3D signal, a 3D signal played back from a recording medium, a 3D signal received from another supplier via a transmission medium such as a video mixer The output of the 3D video processing device, etc. However, for clarity of the description, a brief description of a 3D camera arrangement as one possible source of the 3D signal will be provided.

[0035] refer to figure 1 , shows a system 100 for capturing an image of a scene for use in generating a 3D image. The system 100 has a camera platform 115 on which two cameras 105 are mounted. These cameras 105L and 105R may be video ca...

Abstract

An image analysis apparatus for processing a 3D pair of images representing respective left eye and right eye views of a scene comprises an image crop detector configured to detect the presence of an image crop at a lateral edge of one of the images; and a frame violation detector configured to detect, within areas of the images excluding any detected image crops, an image feature within a threshold distance of the left edge of the left image which is not found in the right image, or an image feature within a threshold distance of the right edge of the right image which is not found in the left image.

Description

technical field [0001] The present invention relates to a method and apparatus for analyzing three-dimensional (3D) video material. Background technique [0002] Three-dimensional (3D) video television has recently become available to consumers, and the number of 3D devices and programs is expected to increase rapidly over the next few years. [0003] 3D television relies on stereoscopic technology, i.e. pairs of images (a pair of images) are captured by corresponding cameras that are laterally (i.e. substantially in the horizontal image direction) a distance apart, e.g. Typical spacing. Image pairs thus represent slightly different views of the same scene; in general, they will contain the same items within the scene (with occasional exceptions at extreme positions of the images), but the relative positions of items between the two images will depend on depends on factors such as camera alignment and the item's distance from the camera placement. [0004] When images are...
