摘要： A stereoscopic camera includes first and second image pickup units, having respectively first and second optical axes, for photographing an object to form two image frames. Two angle adjusters make angle adjustment of the optical axes. An object detector detects a human face as a principal object in the two image frames. An arithmetic processor obtains a shift amount of the face between two image frames, and determines an axial correction angle according to the shift amount for the angle adjustment in consideration of the face. A checker checks whether the angle adjustment should be made for both optical axes or for one thereof. A controller operates at least one of the two angle adjusters according to the axial correction angle and in response to information from the checker, for positioning the face equally between the two image frames optically by adjusting the first and/or second optical axis.
