STEREOSCOPIC IMAGE RECORDING APPARATUS AND METHOD, STEREOSCOPIC IMAGE OUTPUTTING APPARATUS AND METHOD, AND STEREOSCOPIC IMAGE RECORDING OUTPUTTING SYSTEM
First Claim
1. A stereoscopic image recording apparatus comprising:
- a parallax amount measuring device that extracts corresponding points from a set of images of an identical scene captured from different viewpoints to use for displaying a stereoscopic image, detects a parallax amount between each set of the corresponding points, and takes statistics on frequency of occurrence of detected parallax amounts;
a stereoscopic adequacy evaluating device that calculates from said statistics a cumulative frequency of those parallax amounts which are not less than a threshold value, evaluates adequacy of said images for stereoscopic display on the basis of the cumulative frequency, and decides the level of recommendability of said images for stereoscopic display on the scale of at least two grades according to the evaluated adequacy; and
an image storing device for storing said images in associated with recommendability information on the recommendability level decided by said stereoscopic adequacy evaluating device.

Abstract
A digital camera has two imaging units for capturing a pair of parallax images of an identical subject from different viewpoints for use in displaying a stereoscopic image. Parallax amounts between respective corresponding points of these parallax images are detected to calculate a cumulative frequency of the parallax amounts. Based on the cumulative frequency, adequacy of these parallax images for stereoscopic display is evaluated, and these images are recorded in association with information on the evaluated adequacy. Before displaying a stereoscopic image using the parallax images, a digital photo frame refers to the information on the stereoscopic adequacy of these images, and changes its output condition depending on the stereoscopic adequacy.
