Introduction Keystone distortion (aka "perspective distortion") arises when a 3D sequence is photographed with the camera pointing at a fixed ("pivot") point, usually chosen near the scene center. This distortion grows with the camera angular deviation. In lenticular applications, the angular deviation is typically ~5 degrees, and in such a case, the keystone distortion is slight, even hardly noticeable, and is often neglected. As long as the angular deviation is small, one can wonder whether...

How to use the picture's resolution for its depth design? Read this post and find out! Resolution in lenticular pictures It is common knowledge that resolution is an essential characteristic of lenticular pictures, because it determines the depth-blur trade-off; the higher the resolution, the greater the depth that can be displayed without visual defects. However, “resolution” is an elusive concept and can be defined in many ways. This can be confusing, leading to design errors and...

As the saying goes, a picture is worth a thousand words. Building on this idea, a video is worth a thousand pictures. An animated...
