摘要： Three-dimensional information is divided into a plurality of object structures and for each a 2-dimensional plane is set. A set of 2-dimensional images are obtained for each object structure by projecting the object structure onto the corresponding plane, as seen from a plurality of points on a hologram forming surface. In order to electronically produce a hologram, a phase distribution at the hologram forming surface is calculated from the 2-dimensional images of each object structure. The calculated phase distribution is reproduced on a liquid crystal display or the like. A reference light is irradiated onto the phase distribution and is converted into an optical wave front, thereby to display a solid image. In order to form a hologram on a hologram recording medium, each of the 2-dimensional images are exposed on a dry plate at a location corresponding to the location on said hologram forming surface from which the image was viewed.

摘要： A stereoscopic display method whereby a hologram phase distribution is calculated and the calculated 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.

摘要： The position of a solid image which changes with the elapse of time is detected. The position of a virtual screen is set so that its distance from an object enters an allowable range such as to reduce eye fatigue of an observer. A 2-dimensional image is formed at the set virtual screen position. A phase distribution is calculated at the hologram forming surface, thereby displaying a solid image. Thus, even when the position of a solid image changes with the elapse of time, eye fatigue can be minimized.

摘要： An image display to display a 2-dimensional image and a beam deflector to deflect the lights from the pixels constructing the image of the image display are provided. The beam deflector is arranged closely in front of the image display. A plurality of 2-dimensional images of different visual directions are sequentially displayed in the image display. The light from each pixel is deflected by the beam deflector synchronously with the display of the 2-dimensional image so that the light from each pixel is directed to the region in which the visual point has been set in order to obtain each image. The switching operation in this instance is executed at a high speed.

摘要： A hologram surface to express a phase distribution, a visual field in which a solid image can be seen; and a stereoscopic display limit are set in a virtual space. A target to be stereoscopically displayed is subsequently expressed in the virtual space by a set of micro polygons. A plurality of slice planes which are parallel with the horizontal plane are set into the virtual space including the target. The line segments which intersect the polygons are obtained every slice plane. The detected line segment is divided or clipped as necessary and is finally divided into the portion which can be always seen from the whole region of the visual field and a portion which is obstructed by another line segment and can be seen from only a part of the visual field, thereby extracting the line segment. In the calculation of a phase distribution, sampling points are set onto the extracted line segment, a 1-dimensional hologram phase distribution on the hologram surface is calculated every sampling points, and the calculated 1-dimensional hologram phase distributions are added every same slice plane.
