Abstract
According to one embodiment of the present invention a method for capturing images on a screen is disclosed. The method includes directing light from a surface of a spatial light modular to an image field using a projection system; capturing light from the image field using the projection system, the projection system directing at least a portion of the captured light to the spatial light modulator; and directing at least a portion of the received captured light to an image capture system using the spatial light modulator.
Claims21
An image display and capture system comprising:
- a spatial light modulator comprising a surface positioned to direct light to a projection system;
- the projection system positioned to direct light from the spatial light modulator to an image field;
- the projection system also positioned to capture light from the image field and direct at least a portion of the captured light to the spatial light modulator;
- and
- the spatial light modulator also positioned to direct at least a portion of the received captured light to an image capture system.
A method for image display and capture comprising:
- directing light from a surface of a spatial light modular to an image field using a projection system;
- capturing light from the image field using the projection system, the projection system directing at least a portion of the captured light to the spatial light modulator;
- and
- directing at least a portion of the received captured light to an image capture system using the spatial light modulator.
A combined image and camera system comprising:
- an first light source positioned to direct light to a spatial light modulator;
- the spatial light modulator comprising a surface positioned to direct light to a projection system;
- the projection system positioned to direct light from the spatial light modulator to an image field;
- a second light source positioned to direct light to the image field;
- the projection system also positioned to capture light from the image field and direct at least a portion of the captured light to the spatial light modulator;
- and
- the spatial light modulator also positioned to direct at least a portion of the received captured light to an image capture system.
