Patent ID: 8878915

Claim:
An image processing device comprising: a location error determination unit configured to determine, prior to displaying on a display device stereoscopic images including a parallax image for the left eye and a parallax image for the right eye of a subject, using luminance distribution and bidirectional computation whether the parallax image for the left eye and the parallax image for the right eye are stereoscopic images that can be located as three-dimensional images; a parallax error determination unit configured to determine a reliability of matching, when it is determined that the parallax image for the left eye and the parallax image for the right eye can be located as stereoscopic images, whether a range of distribution of parallax between the parallax images for the left eye and the parallax image for the right eye is accommodated within a predetermined parallax range; an error communicating unit configured to communicate an error when it is determined that the parallax image for the left eye and the parallax image for the right eye cannot be located as stereoscopic images or when it is determined that the range of parallax between the parallax image for the left eye and the parallax image for the right eye is not accommodated within the predetermined parallax range; and a reliability determination unit configured to refer to a feature determined by characteristics confined to the parallax image for the left eye and the parallax image for the right eye and not depending on a relation between the parallax image for the left eye and the parallax image for the right eye, so as to identify an area in which a reliability of matching between the parallax image for the left eye and the parallax image for the right eye is established, wherein the reliability of matching is in indicator indicating a sharpness of image edges between the parallax image for the left eye and the parallax image for the right eye, and wherein the location error determination unit determines that the parallax image for the left eye and the parallax image for the right eye are not stereoscopic images that can be located as three-dimensional images when a ratio occupied by an area in which the reliability of matching between the parallax image for the left eye and the parallax image for the right eye is established with respect to the entirety of the parallax image for the left eye and the parallax image for the right eye is a predetermined ratio or lower.
