  • Patent number: 5757545
    Abstract: This disclosure is concerned with a lenticular or barrier strip picture with changeable scenes wherein a trimmed lenticular screen or a barrier strip plate is used to view a composite image. On a conventional lenticular picture, the focal plane of the lenticules on the lenticular screen coincides with the backside of the lenticular screen and, therefore, the composite image must be placed in contact with the backside of the lenticular screen. On the lenticular picture according to the present invention, the thickness of the lenticular screen is trimmed such that the focal plane of the lenticules is located further away from the backside of the lenticular screen. In order that a composite image can produce a properly focused composing scene when viewed through the trimmed lenticular screen, it must be positioned on the focal plane of the lenticules away from the backside of the screen, leaving an airgap therebetween. With in such an airgap, a holding plate is disposed to hold down said composite image.
