Abstract: 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.
