Video projection apparatus and methods, with image content control
First Claim
1. An image projection and control system, comprising:
- a device including a projector and a display controller operative to project an image onto a surface;
an image sensor operative to view the projected image on the surface;
a handheld device outputting a beam of visible light;
a memory in communication with the controller for storing information regarding one or more predetermined visual interactions between the projected image and light from the handheld device; and
wherein the controller is operative to perform the following functions;
(a) receive information from the image sensor regarding the presence or movement of light from the handheld device interacting with the projected image on the surface, and(b) implement a control function if the light from the handheld device interacts with the projected image in accordance with one of the stored predetermined visual interactions, the control function causing a change in the content of the projected image.

Abstract
A projected still or video image is controlled with light generated by a laser pointer, for example. A device with a projector and a display controller projects an image onto a surface, and an image sensor views the projected image. A handheld device outputs a beam of light. A controller receives information from the image sensor regarding the presence or movement of light from the handheld device interacting with the projected image on the surface, and a control function is implemented if the light from the handheld device interacts with the projected image in accordance with a stored predetermined visual interactions such as encircling, “scratching,” or other movements. The controller may be programmed to recognize light of a specific laser wavelength in conjunction with a control operation.

11. An image projection and control method, comprising the steps of:
-
projecting an image onto a surface; viewing the projected image with an image sensor; directing a beam of visible light at the projected image; storing information regarding one or more predetermined visual interactions between the projected image and light from the beam; receiving information from the image sensor regarding the presence or movement of light from the beam interacting with the projected image on the surface; and implementing a control function if the light from the beam interacts with the projected image in accordance with one of the stored predetermined visual interactions, the control function causing a change in the content of the projected image. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21)
