摘要： 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. Preferably, the holding plate is movably mounted to allow the composite image to be changed out and replaced by another composite image.
摘要翻译：本公开涉及具有可变场景的透镜或阻挡带图像，其中使用修剪的透镜屏或屏障条板来观看合成图像。在常规透镜图像上，透镜屏幕上的微透镜的焦平面与透镜屏幕的背面重合，因此，复合图像必须与双凸透镜屏幕的背面接触。在根据本发明的透镜图片上，修整双凸透镜的厚度，使得微透镜的焦平面位于更远离透镜屏幕的背面的位置。为了使复合图像能够通过经过修剪的透镜屏幕观察而产生适当聚焦的合成场景，它必须被定位在远离屏幕背面的微透镜的焦平面上，在屏幕之间留有气隙。在这样的气隙中，设置有保持板来压住所述复合图像。优选地，保持板可移动地安装以允许合成图像被改变并由另一合成图像代替。
