Abstract
A method and apparatus for projecting images, advertisements and the like to passengers of moving vehicles. A projector is placed on the vehicle and it projects an image on the walls of a train tunnel, clouds near an airplane, etc. as the vehicle moves. A technique is provided for correcting distortion caused by the positional changes between the vehicle and the projection surface.
Claims17
Apparatus for displaying images to passengers of a moving vehicle comprising:
- projecting means mounted on said vehicle for projecting an image onto a surface proximate to said vehicle;
- and
- means for adjusting the location of said image on said surface as the relative positions of said surface and said vehicle change such that said image remains conveniently viewable to passengers of said vehicle despite changes in said relative positions, wherein said projecting means is mounted on motion damping means.
Apparatus for displaying images to passengers of a moving vehicle comprising:
- projecting means mounted on said vehicle for projecting an image onto a surface proximate to said vehicle;
- means for adjusting the location of said image on said surface as the relative positions of said surface and said vehicle change such that said image remains conveniently viewable to passengers of said vehicle despite changes in said relative positions;
- and a digital guidance unit for calculating an adjustment to be made to said projecting means and for moving said projecting means to effectuate said adjustment.
A method of projecting a viewable image for passengers within a moving vehicle comprising the steps of:
- projecting the image on a surface proximate to said moving vehicle;
- detecting changes in the position of said surface relative to said vehicle;
- and
- adjusting said projecting step in accordance with detected positional changes to cause the image to be continually correctly projected on the surface.
Apparatus for displaying an image to airplane passengers comprising;
- means mounted on said airplane for projecting an image onto clouds;
- and
- means for maintaining the focus of the image onto clouds located a distance from the airplane.
An apparatus for displaying images to passengers of a moving vehicle comprising:
- an image projector mounted on the vehicle for projecting an image outside the vehicle at a location in a passenger's line of view;
- a sensing device mounted on the vehicle capable of monitoring changes in said location relative to the projector;
- and
- a digital guidance unit in communication with the sensing device for calculating an adjustment to be made to the projector and for moving the projector to effectuate appropriate adjustment, thereby maintaining desired focus of the image.
