The basic principle of one-step holographic stereogram printing method based on effective perspective images' segmentation and mosaicking (EPISM) is briefly introduced. The influence of EPISM method on the reconstructed quality change of different scene depths is analyzed. The causes of visual hopping in holographic stereogram based on EPISM are studied. The curvature distortion of holographic stereogram is also analyzed. The effect of curvature distortion on the reconstructed quality of holographic stereogram is verified. The reconstructed quality of the three dimensional scene with short depth is effectively improved when we reduce the size of holographic hogel.
