Abstract
Described is a dynamic correction of keystone distortions of a dynamically panning and tilting luminaire projecting on a flat projection surface. When the luminaire is panned and/or tilted the proper degree of keystone correction is applied. Further the system dynamically corrects for varying of intensity of different parts of the projected image due to the none linear distribution of light on the projection surface as the luminaire is dynamically panned and or tilted relative to the projection surface.
Claims7
An automated multiparameter luminair system comprising
- light source for generating a light beam;
- actuators for dynamically panning and/or tilting the position of the light beam on a flat projection surface;
- data processing routines for determining keystone corrections based on the calculated position(s) of the light beam on the projection surface where the corrections are made dynamically, and automatically when the actuators change the pan and or tilt position of the light beam on the projection.
An automated multiparameter luminair system comprising
- light source for generating a light beam;
- actuators for dynamically panning and/or tilting the position of the light beam on a flat projection surface;
- data processing for determining light intensity corrections for the projection of an image that has keystone distortions due to the projection angle of the light source on the projection surface.
