Abstract

In an embodiment, an apparatus includes a projection subsystem to project an image-containing beam, and an image adjustment element. The image adjustment element is to cause adjustment of the image-containing beam in response to a detection of relative movement of the apparatus with respect to a reference object. A method includes determining whether substantial relative movement of a projection system has been detected, in an embodiment. When substantial relative movement has been detected, the method further includes producing control inputs, and altering operation of one or more image adjustment elements and/or altering image data in response to the control inputs, in an embodiment.
