A stereo camera with an automatic convergence adjusting device is provided. A stereo-image is captured by a CCD through a stereo adapter. A fiducial light beam in a plane of symmetry which includes a perpendicular bisector line of a segment between the viewpoints of the right and left parallax images, is projected onto a subject from light-emitting equipment. A fiducial spot produced by the fiducial light beam is imaged on both the right and left parallax images and the image loci of the fiducial spot are detected. The convergence of the stereo adapter is adjusted with reference to the image loci of the fiducial mark.
