Apparatus, method and computer program product for three-dimensional image processing
First Claim
1. An apparatus for processing a three-dimensional image, the apparatus comprising:
- a specified value acquiring unit that acquires characteristics of a stereoscopic display unit as specified parameters, the stereoscopic display unit displaying a multi-viewpoint image that is created by mapping each pixel position included in a plurality of viewpoint images in accordance with the characteristics of the stereoscopic display unit;
an observation value acquiring unit that acquires observation parameters indicating observation values of a stereoscopic image displayed on the stereoscopic display unit;
a calculating unit that calculates conversion information indicating inverse mapping of the mapping based on the specified parameters;
an observation value converting unit that converts the observation parameters into converted parameters of the same dimension as the viewpoint images based on the conversion information; and
a control unit that controls image processing on a viewpoint image corresponding to each pixel position of the stereoscopic image with respect to each of the viewpoint images based on the converted parameters.
