Abstract:
A system displays a collection of stationary images as a motion picture to passengers travelling in a vehicle along a pathway. The vehicle moves at a known speed and known distance from the images. The system includes an image illumination system including stroboscopic lighting for each image. The images, placed in parallel along the walls of the pathway of the vehicle, are adapted in number, size, and spacing for a vehicle travelling at the known speed and at the known distance from images on one or both sides of the vehicle such as to maintain an approximately constant viewing rate and perceived size of the images. The system includes mounting mechanisms for positioning each image vertically and at a constant distance from the train regardless of unevenness in wall contour. Glare due to interior lighting in the vehicle is reduced or eliminated by selecting the appropriate illumination intensity for the stroboscopic lighting.
