Abstract
The described system 100 provides a digital luminaire 102 which provides optical distortion correction across a wide range variable beam luminaire using lower cost lighter, simpler more efficient higher output optical drives 106 resulting in luminaires 102 that generate higher light output 120-122-124 with lighter units at lower cost over a larger range of beam angles without image distortion.
Claims19
A digital luminaire comprised of:
- an imaging light source which can receive digital image data which employs a zoom optical lens which optically distorts images processed through it in a discernable pincushion and/or barrel pattern(s) that varies across a zoom range of the optical lens drive;
- a media server for processing digital images fed to the digital light beam engine together with information related to the zoom range position of the optical lens and stored predistortion algorithm to predistort the digital image to counteract the optical distortion caused by the optical lens.
A digital luminaire comprised of:
- a imaging light source which can receive digital image data which employs an optical lens which optically distorts images processed through it in a discernable pattern;
- a processor for processing digital images fed to the digital light beam engine which applies a stored predistortion algorithm to the digital image to counteract the optical distortion caused by the optical lens.
A digital luminaire projection system comprising of:
- a imaging light source which can receive digital image data which employ an optical lens which optically distorts images processed through it in a discernable pattern;
- a media server for processing digital images fed to the digital light beam engine which applies a stored predistortion algorithm to the digital image to counteract the optical distortion caused by the optical lens.
