First Claim
1. An image data analyzing apparatus, comprising:
- a monocular visual depth information determiner for receiving stereoscopic image data of time-division display type composed of a left image for a left eye of a user and a right image for a right eye of the user, and determining a first anteroposterior relationship of regions contained in an image frame of one of the left image and the right image;
a binocular visual depth information determiner for receiving the stereoscopic image data of time-division display type, selecting an image assumed to be the left image and an image assumed to be the right image, and determining a second anteroposterior relationship of regions contained in an image frame of a plurality of images containing the selected left image and right image; and
a left-right image discriminator for receiving a first determination result relating to the first anteroposterior relationship from the monocular visual depth information determiner, and a second determination result relating to the second anteroposterior relationship from the binocular visual depth information determiner, comparing the first determination result with the second determination result, determining that an assumption set by the binocular visual depth information determiner is correct if a rate of agreement between the first determination result of the monocular visual depth information determiner and the second determination result of the binocular visual depth information determiner is equal to or higher than a predetermined threshold value, and outputting identification information representing whether each image frame of the stereoscopic image data is the left image or the right image as identification information in agreement with the assumption.

Abstract
An image data analyzing apparatus includes a monocular visual depth information determiner for determining the anteroposterior relationship of regions contained in an image frame of one of a left image and a right image forming stereoscopic image data of time-division display type, a binocular visual depth information determiner for determining the anteroposterior relationship of regions contained in a plurality of images assumed to be the left image and right image, and a left-right image discriminator for outputting left-right image identification information in agreement with an assumption of the binocular visual depth information determiner if a pair of determination results show a high rate of agreement, and outputting left-right image identification information in agreement with a reverse setting of the assumption if the pair of determination results show a low rate of agreement.
