Claims
- 1. A method of displaying still images on a backboard that appear animated to viewers in motion, said method comprising:
selecting a side profile for said backboard; representing said selected profile mathematically; selecting an optimal viewer position; selecting a worst case viewer position; calculating a magnification factor for said optimal viewer position; calculating a magnification factor for said worst case viewer position; determining whether said magnification factors result in acceptable observable images; preshrinking images in accordance with said magnification factor for said optimal viewer position when said magnification factors are determined to result in acceptable observable images; and mounting said preshrunk images on said backboard.
- 2. The method of claim 1 wherein said selecting a side profile comprises selecting a side profile in accordance with available installation space.
- 3. The method of claim 1 wherein said selecting a side profile comprises selecting a nonplanar side profile for said backboard.
- 4. The method of claim 1 wherein said selecting a side profile comprises selecting a planar side profile for said backboard.
- 5. The method of claim 1 wherein said representing comprises representing said selected profile mathematically by approximation.
- 6. The method of claim 1 wherein said determining comprises determining whether a difference between said magnification factors exceeds a preset magnification limit.
- 7. The method of claim 6 wherein said preset magnification limit is +/−10% of the difference between said magnification factors.
- 8. The method of claim 1 further comprising selecting a side profile for a slitboard, said slitboard comprising a plurality of slits through which said images can be seen by said viewers in motion.
- 9. The method of claim 8 wherein said selecting a side profile for a slitboard comprises selecting a side profile for a slitboard that is identical to said selected side profile for said backboard.
- 10. The method of claim 1 further comprising illuminating said preshrunk images from behind said backboard, said backboard facing said viewers in motion.
