Holographic steroscopic display method and apparatus using high and low sample point densities of feature and non-lecture portions of a holographic sterogram |
摘要 |
A stereoscopic display method whereby a hologram phase distribution is calculated and the calculated phase distribution is expressed and the expressed phase distribution is converted into a wave front of the light, thereby displaying a solid image. Further, a feature portion in a display target specified by 3-dimensional information is detected. Sampling points are set at a high density into the detected feature portion. Sampling points are set at a low density with respect to a non-feature portion as a portion other than the feature portion. In the phase calculation, a hologram phase distribution is calculated with respect to the set sampling points.
