A camera has one or more rows of imaging lenses and an imaging sensor to capture a plurality of images formed by the imaging lenses. Each pair of the imaging lenses in a row is separated by an inter-lens spacing and the inter-lens spacing of any one pair of the imaging lenses is different from the inter-lens spacing of another pair. An image selection device is used to select the images formed by two imaging lenses for making a three-dimensional image. The number of the imaging lenses is three or more.
