The digital projector may include a video projector. The digital projector may include an additional computer enabling remote management of the video projector and camera, the camera enabled for remote control of zoom, focus and filter lens. An access point may allow wireless control of the video projector and camera. The ceiling mount may be a VESA fixture. The projection system and camera may be combined into a single unit to allow interactivity between what is viewed by the camera and what is displayed by the system. The camera may an infra-red camera, or optimised for IR. The camera may provide a video feed to the computer, which processes the feed to track and/or recognise objects such as a clicker designed to be seen in IR.

DIGITAL PROJECTOR
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a digital projector. One application is a digital projector that projects food or drink menu ordering options onto a table.
2. Description of the Prior Art
Digital projection systems, including those specifically for projecting food or drink menu ordering options onto a table are known from WO 2008/071979, WO 2011/064599 and WO 2011/124928, the contents of which are incorporated by reference.
WO 2011/064599 describes using a digital projector to display food or drink menu ordering options onto a table, and a separate web cam to view and detect the presence of certain objects on the table top that can be moved by a user to generate control inputs, such as selecting a specific menu item.
One disadvantage of this arrangement is that it is time consuming to set-up.
BRIEF SUMMARY OF THE INVENTION
A first aspect of the invention is a digital projector including a digital projection system, a digital video camera and a computer that controls both the digital projection system and the digital video camera, all integrated within a housing that is configured for ceiling mounting.
By integrating the projector and camera together into a single housing, set-up is much faster and easier than if there is a separate web-cam to mount close to the projector. Operation and management is easier too.
Features in an implementation include the following: * An additional computer in the housing enables remote management of both the video projector and the video camera.
* A wireless access point is included in the housing to control both the projector and the video camera.
* An integrated power supply in the housing provides power for both the video camera and the projector, so that the housing unit needs just a single power cable, a significant advantage when installing the system.
* A ceiling mount is provided for the housing, instead of separate ceiling mounts for the projector and the web-cam.
* A cooling system in the housing cools both the video camera and the projector.
* The projector and camera can also be managed and controlled using the same main computer (or 'controlling computer') and hence the same software suite; zoom and focus for both the projector lens and the video camera lens can all be controlled using an integrated software package.
Hence, there can be numerous practical advantages to integrating a digital projection system, a digital video camera and a computer all within a single ceiling mounted housing.
Other optional features of the invention are the following: * Projector includes or is attachable to a standard VESA (Video Electronics Standards Association) ceiling mount.
* Camera is an infra-red camera.
* Combining the digital projection system and a digital camera into a single unit enables interactivity between what is viewed by the digital video camera and what is displayed by the projection system.
* Computer manages and controls both the video ca mera and also the digital projector.
* Video camera provides a video feed to the computer and the computer processes that video feed to track and/or recognise objects.
* Video camera provides a video feed to the computer and the computer processes that video feed to track and/or recognise objects and control or alter the image displayed by the projection system to enable interactivity.
* Video camera is optimised for IR and provides a video feed to the computer and the computer processes that video feed to track a clicker or puck or other object designed to be seen in IR.
* Gesture-based control inputs are viewed by the camera and interpreted by the computer and lead to the images being displayed by the projector being controlled; option buttons or regions displayed by the projector can be selected by the user through gestures.
* Video camera is enabled for remote control of zoom, focus and filter lens.
* The projection system and the video camera share the same lens or imaging system (e.g. using a 45° angle pellicle or semi-silvered mirror that the projector beams straight through; the camera then receives light reflected from the 45° angle pellicle or semi-silvered mirror) * The projection system and the video camera use a different lens or imaging system.
* Digital projector projects images onto a horizontal surface, such as a table or desk.
* Digital projector projects images onto a vertical surface, such as a wall or projection screen.
* Digital projector is used in a restaurant to project an interactive food and/or drink ordering menu.
* Digital projector is used in a school to project interactive educational content.
* Digital projector is used in a retail or commercial environment to project entertainment or information content.
* Digital projector receives control inputs from a user to control the position of a cursor displayed by the projector.
