IMAGE DISPLAY DEVICE, IMAGE DISPLAY METHOD, AND PROGRAM
First Claim
1. An image display device, comprising:
- a region of interest extraction unit that generates a depth image signal by depth image conversion employing a depth threshold, the depth image signal including information on a distance in a three-dimensional space between a viewpoint and each pixel of a two-dimensional image including a region of interest desired to be noted by an observer, the depth image conversion being such that a depth value indicating the distance between the viewpoint and each pixel of the two-dimensional image is converted to a depth value for 2D display when the depth value is equal to or larger than the depth threshold;
a parallax image generation unit that generates a left-and right-eye parallax images each having a parallax in the region of interest and having no parallax in a region other than the region of interest, from said two-dimensional image and an image obtained by conversion of a region of interest image to be displayed in the region of interest at each of right and left viewpoints, based on said two-dimensional image and said depth image signal; and
a 3D image display unit that displays the left-eye parallax image and the right-eye parallax image.

Abstract
An image display device includes region of interest extraction unit, parallax image generation unit and 3D image display unit. Region of interest extraction unit generates depth image signal by depth image conversion employing depth threshold, depth image signal including information on distance in three-dimensional space between viewpoint and each pixel of two-dimensional image including region of interest desired to be noted by observer, depth image conversion being such that depth value indicating distance between viewpoint and each pixel of two-dimensional image is converted to depth value for 2D display when depth value is equal to or larger than depth threshold. Parallax image generation unit generates both-eye parallax image having parallax in region of interest alone, from two-dimensional image and image obtained by conversion of region of interest image representing region of interest at each of both-eye viewpoints, based on two-dimensional image and depth image signal. 3D image display unit displays both eye parallax image.
