LIGHT-FIELD CAMERA
First Claim
1. A light-field camera for capturing multiple views of a scene, the multiple views representing samples of a light-field, the light-field camera comprising:
- a primary camera configured for capturing a primary digital two-dimensional image of the scene;
a two-dimensional camera array comprising a plurality of secondary cameras, wherein each of the secondary cameras is configured for capturing a secondary digital two-dimensional image of the scene in order to produce at least one set of secondary digital two-dimensional images of the scene;
a semitransparent mirror arranged in such way that an incident light beam originating from the scene is split up in a first partial light beam, which is directed to the primary camera, and a second partial light beam, which is directed to the camera array; and
a processing unit configured for receiving the primary digital two-dimensional image and the at least one set of secondary digital two-dimensional images and configured for computing depth information for the primary digital two-dimensional image or a digital two-dimensional image corresponding to the primary digital two-dimensional image based on the set of secondary digital two-dimensional images.

Abstract
The invention provides a light-field camera for capturing multiple views of a scene, representing samples of a light-field, having: a primary camera configured for capturing a primary digital two-dimensional image of the scene; a two-dimensional camera array having a plurality of secondary cameras, each of the secondary cameras being configured for capturing a secondary digital two-dimensional image of the scene to produce at least one set of secondary digital two-dimensional images of the scene; a semitransparent mirror arranged such that an incident light beam originating from the scene is split up in a first partial light beam, directed to the primary camera, and a second partial light beam, directed to the camera array; and a processing unit configured for receiving the primary digital two-dimensional image and the at least one set of secondary digital two-dimensional images and configured for computing depth information for the primary digital two-dimensional image or a digital two-dimensional image corresponding to the primary digital two-dimensional image based on the set of secondary digital two-dimensional images.

25. A method for capturing multiple views of a scene, the multiple views representing samples of a light-field, the method comprising:
-
capturing a primary digital two-dimensional image of the scene using a primary camera; producing at least one set of secondary digital two-dimensional images of the scene using a two-dimensional camera array comprising a plurality of secondary cameras, wherein each of the secondary cameras is configured for capturing a secondary digital two-dimensional image of the scene; providing a semitransparent mirror arranged in such way that an incident light beam originating from the scene is split up in a first partial light beam, which is directed to the primary camera, and a second partial light beam, which is directed to the camera array; and receiving the primary digital two-dimensional image and the at least one set of secondary digital two-dimensional images and computing depth information for the primary digital two-dimensional image or a digital two-dimensional image corresponding to the primary digital two-dimensional image based on the set of secondary digital two-dimensional images using a processing unit. - View Dependent Claims (26)
