Imaging apparatus and control method therefor, and 3D information obtaining system

摘要

In a pantoscopic camera, right and left images, which overlap with each other, are captured from a subject. Overlap areas are detected from these images, and a composite image is produced from either of the overlap areas and non-overlap areas of the respective images. So long as a shutter button is not operated, the right and left images are successively captured to display the composite image as a moving through-image on an LCD. When the shutter button is pressed halfway, the LCD is switched from the composite image to an overlap area image that corresponds to the overlap area. On the basis of the detected overlap areas, 3D information on the subject may be obtained, or a stereoscopic image may be displayed.
