Abstract
A three-dimensional display device includes a plurality of transmissive display units arranged in different depth positions in view from an observer and a moiré vanishing element for diffusing light. The moiré vanishing element has a spatial frequency characteristic to cut off a spatial frequency more than a spatial frequency having a cycle being twice as large as an interval of boundaries of pixels forming a first transmissive display unit arranged behind the moiré vanishing element in the view from the observer.
Claims16
A three-dimensional display device comprising:
- a plurality of transmissive display units arranged in different depth positions in view from an observer;
- and a moiré vanishing element that diffuses a light, where in the moiré vanishing element has a spatial frequency characteristic to cut off a spatial frequency more than a spatial frequency having a cycle being twice as large as a width of black matrix between pixels forming a first transmissive display unit arranged behind the moiré vanishing element in the view from the observer.
An image presentation method comprising:
- arranging a plurality of transmissive display units and a moiré vanishing element for diffusing light in different depth positions in view from an observer:
- enhancing an original image so that the observer can see an image close to the original image when viewing a transmissive display unit behind the moiré vanishing element in view of the observer;
- and
- allowing the transmissive display unit behind the moiré vanishing element in view of the observer to display the image enhanced,
- wherein the moiré vanishing element has a spatial frequency characteristic to cut off a spatial frequency more than a spatial frequency having a cycle being twice as large as a width of black matrix between pixels forming the transmissive display unit.
