It is shown when being exposed on printed material 60, these methods can be used as to fill gap.
Another way for filling the gap in 3D photo is the quantity N for increasing image to be exposed, so as to N=
θ/Δθ.For example, if two images 32 and 34 are used to synthesis 3D photo (referring to Figure 10 A), but two compression images are simultaneously
The entire substrate of lenticule is not filled up properly, then the quantity for showing image can be increased to four to compress image
