Holgraphic display with switchable aspect ratio
First Claim
1. A computer program product for changing an aspect ratio in a display system comprising a first holographic system operable to display an image with a first aspect ratio and a second holographic system operable to display the image with a second aspect ratio different from said first aspect ratio, comprising a computer usable medium having machine readable code embodied therein for:
- switching on the first holographic system so that the holographic system diffracts light passing therethrough to form an image with said first aspect ratio; and
switching off the second holographic system so that the holographic system allows light to pass therethrough without diffraction of the light.

Abstract
A holographic display system comprising left and right optical systems is disclosed, The optical systems each comprise an image display operable to display an input image and first and second holographic devices. The first holographic device is operable to project the input image to overlap with the input image projected from the other of the left and right optical systems to form a resultant image with a first aspect ratio. The second holographic device is operable to project the input image to overlap with the input image projected from the other of the left and right optical systems to form a resultant image with a second aspect ratio, different from the first aspect ratio. A method of changing the aspect ratio of an image is also disclosed.

6. An imager comprising first and second imaging systems, each imaging system configured to receive an input image and including a holographic device configured:
-
in a first mode, to direct the input image to at least partially overlap with the input image directed by the other imaging system to form a first resultant image; and
in a second mode, to direct the input image to at least partially overlap with the input image directed by the other imaging system to form a second resultant image distinct from the first resultant image. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)

-
using an imaging system to direct the input image to at least partially overlap with the input image directed by the other imaging system to form a first resultant image; and
using an imaging system to direct the input image to at least partially overlap with the input image directed by the other imaging system to form a second resultant image having a dimension distinct from the first resultant image. - View Dependent Claims (29)
