Abstract

A camera that is adapted to present a preview image is provided. The camera has a trigger adapted to generate a trigger pulse and an image capture system for capturing images of a scene. A viewer is adapted to present one image to a first viewing area and another image to a second viewing area. A controller is adapted to receive a first trigger pulse and to cause the image capture system to capture a first image of the scene in response to the first trigger pulse. The controller is also adapted to receive a second trigger pulse and to cause the image capture system to capture a second image of the scene in response to the second trigger pulse and to cause the viewer to simultaneously present the first image to the first viewing area and to present the second image to the second viewing area. An observer positioned with a first eye in the first viewing area and a second eye in the second viewing area can detect parallax differences between the first image and the second image.
