ABSTRACT:
A stereo-graphic apparatus has first and second imaging devices to provide a first image and a second image, respectively. The first and the second imaging device are spaced from each other to define a predetermined convergence angle. A distance detecting apparatus detects distance from the first and the second imaging device to an object for imaging. A first electric zooming apparatus receives a signal from the first imaging device and extracts image data of a predetermined area from the first image. A second electric zooming apparatus receives a signal from the second imaging device and extracts image data of a predetermined area of image. A control device controls the extraction of image data according to the distance information. According to the distance information, the extracting area is moved so that the focused object is located on the center of each of the provided images. As a result, the convergence angel is substantially changed according to the distance between the object and the imaging device.
