摘要： A conventional device adjusts the convergence angle of its imaging unit in a manner that the left-and-right face detection areas are at the same coordinates and thus forms a stereo image that will be placed on a display screen during display, but fails to place a subject at an intended stereoscopic position. A stereo image capturing device (1000) detects a face area from a right image, detects a disparity using the left-and-right face areas, and sets the imaging parameters (the subject distance, focal length, stereo base, and convergence angle) to adjust the detected disparity to a disparity enabling the subject to be placed at an intended placement position. This device forms a stereo image having an appropriate stereoscopic effect in which a target subject is placed at an intended stereoscopic position. The device uses only a limited target area for face detection and thus requires less calculation for face detection.

摘要： A conventional stereo image pickup device forms an appropriate stereo image by changing the stereo base in accordance with the distance to a subject, but fails to select an appropriate focal length or stereo base by simply using the subject distance without obtaining the subject size. A stereo image pickup device (1000) estimates the size of a subject in accordance with the imaging mode set in a typical two-dimensional camera, and estimates the subject distance using the estimated size of the subject and the focal length, and further calculates the stereo base that enables an optimum disparity to be achieved using the subject distance, determines the stereo base, and aligns the two imaging units (the first imaging unit (103) and the second imaging unit (104)). As a result, the stereo image pickup device forms a stereo image having an appropriate stereoscopic effect.
