Stabilized image projecting device
First Claim
1. A device for optically projecting at least a first image and a pointer pattern on an external surface, said device comprising:
- an image projecting unit for optically projecting at least said first image and said pointer pattern on said external surface,a sensor to provide movement information related to angular movement of said device with respect to said external reference,one or more actuators for mechanically adjusting the position of said first image, anda control unit to move the position of said first image with respect to said pointer pattern according to said movement information by using said one or more actuators such that the relative movement of said first image with respect to said external reference is substantially smaller than the relative movement of said pointer pattern with respect to said external reference.

Abstract
A handheld projecting device is adapted to project an image and a pointer pattern on an external surface. The projecting device comprises a sensor to detect the movements of the projecting device and means to dampen the movements of the projected image, based on the detected movements of the projecting device. When the handheld projecting device is turned, the position of the projected image is kept substantially stationary whereas the pointer pattern moves on the projected image to indicate a point of the projected image. In an embodiment, the pointer pattern may be used to make a selection between graphically displayed options.
