[0041] figure 1 Part A of is a diagram conceptually showing a three-dimensional image generating system according to the first embodiment of the present technology. figure 1 Part B of is a plan view of the three-dimensional image generating system 50 viewed from the top. The three-dimensional image generating system 50 includes a projector 10 serving as an image light source and an image light 11 from the projector 10 projected onto the three-dimensional screen structure 20 , and a three-dimensional screen structure 20 .

[0042] As the projector 10, a projector having a general structure and function is used. The image data projected from the projector 10 may be a general 2D image. The "image" used in this article includes both static images and dynamic images.

[0043] A three-dimensional screen structure 20 shown in a partially enlarged manner in the drawing includes a plurality of particles 21 and a binding unit 25 binding these particles 21 . The term "to bind" means ...

[0070] Figure 4 is a plan view schematically showing a three-dimensional image generating system including a plurality of projectors 10 as a second embodiment.

[0071] In this example, for example, five projectors 10 are arranged around the three-dimensional screen structure 20 at regular intervals, and the intervals are within a range of 180°. The traveling direction (direction of the main optical axis) of light from these projectors 10 is different from each other. The projector 10 is arranged such that all light is directed to the center of the three-dimensional screen structure 20 . Further, the image data projected from the corresponding projectors 10 respectively have parallaxes associated with the layout relationship of the projectors 10 . Accordingly, a three-dimensional image including three-dimensional information is projected onto the three-dimensional screen structure 20 . When changing the observation position (observation angle of the three-dimensional scree...

[0075] Figure 5 is an enlarged view of another example of the three-dimensional screen structure as the third embodiment. In this embodiment, three or more linkers 26 extend from one particle 21 . Particles 21 are randomly arranged. The tethering unit 25 is of little use for image generation, and it is therefore desirable that its volume be as small as possible. However, in view of the hardness between particles 21, the greater the number of linkers 26, the higher the degree of synthesis. In this embodiment, the hardness between the particles 21 and finally the hardness of the three-dimensional screen structure is prioritized, and thus the volume of the confinement unit 25 is increased.

Abstract

[Solution] A three-dimensional screen structure is configured to receive image light projected from an image light source. The three-dimensional screen structure is provided with a plurality of grains and a binder. The plurality of grains is three dimensionally disposed, and is capable of transmitting or reflecting the image light. The binder is provided to bind the plurality of grains.

Description

technical field [0001] The technology relates to a three-dimensional image generating system for generating a three-dimensional image, and to a three-dimensional screen structure for displaying a three-dimensional image in the three-dimensional image generating system. Background technique [0002] A typical holography technique is, for example, a technique of causing reference light and signal light to interfere with each other and recording the interfered light on a hologram recording medium. In other words, at the time of recording, a light and dark pattern of interfering light (ie, its intensity and phase) is recorded on the recording medium. When reproducing signal light, the recording medium is irradiated with interference light, and thus diffracted light is generated from the recording medium. The observer can see the diffracted light as a stereoscopic image. [0003] Patent Document 1 discloses an apparatus that irradiates a detector such as an image sensor with re...
