Three-dimensional image processing apparatus, three-dimensional imaging apparatus, and three-dimensional image processing method

摘要

A three-dimensional image processing apparatus which processes a captured image of a scene using distance information indicating a distance of the scene from a camera, and includes: a distance designation unit which receives input of a designated distance that is a target distance in which a stereoscopic effect is to be emphasized; a distance conversion unit which converts the distance indicated in the distance information into a stereoscopic distance for generating three-dimensional images, to emphasize the stereoscopic effect of the scene in the designated distance; and an emphasized image generation unit which, by processing the captured image based on the stereoscopic distance, generates an emphasized image representing the stereoscopic effect to be emphasized in the designated distance.

1. A three-dimensional image processing apparatus which processes a captured image of a scene using distance information indicating a first distance of the scene from a camera, the three-dimensional image processing apparatus comprising:
a distance designation unit configured to receive input of a user-selected designated distance that is a target distance in which a stereoscopic effect is to be emphasized; a distance conversion unit configured to convert the first distance indicated in the distance information into a second distance that is represented in a distance image and used for generating three-dimensional images, and to emphasize the stereoscopic effect of the scene at the designated distance by selecting a change amount of the second distance with respect to the first distance that is largest at the designated distance; an emphasized image generation unit configured to generate a texture image based on the captured image, and to generate an emphasized image by processing the texture image to cause more blur to be included in a region where the change amount is largest, the emphasized image being an image in which the stereoscopic effect perceived by a viewer is emphasized according to the designated distance; and a disparity image generation unit configured to calculate a shift amount of each pixel of the texture image based on the distance image, and generate a pixel-shifted image by shifting each pixel of the texture image by the calculated shift amount, to generate, as the three-dimensional images, paired stereoscopic images including the texture image and the pixel-shifted image.
