A general purpose image and visual effects display apparatus, with associated methods, which is comprised of an array of independently angled reflective or refractive elements wherein the varying angle pattern of each element across said array is designed to reflect or refract specifically designed as well as fortuitously located existing colors, in precisely determined patterns, to make apparent to specific viewing or receiving locations a wide range of complex emergent visual and other effects. In some embodiments very high resolution and high color fidelity image display is possible. In other embodiments moving images akin to video can be displayed, using no electronics or moving parts. In other embodiments true binocular 3D images can be displayed directly to viewers, without the need for special 3D viewing glasses. Many of the embodiments and methods are applicable to non-visible light and other reflectable wave-based phenomena.

Volumetric three-dimensional (3-D) graphical or computer displays are disclosed herein that are capable of presenting objects, data, scenes or other visual information in a realistic or solid-like manner, allowing for an unaided observer to observe such static or moving objects from multiple perspectives with natural depth-cues and superior image quality. We utilize in this refined approach moving-screens formed from particulate-arrays and we preferably optically project multiple image sub-slices on each such flying-screen as it passes through the image-volume thereby minimizing particulate mass-flow since only once screen per image-volume is needed to present the several or many necessary slices of each volumetric frame.

A display apparatus has a lens sheet with a plurality of unit columnar lenses arranged so as to be parallel to one another, and is disposed on the observation side of a display panel, spaced therefrom by a layer of air. The direction of the ridge lines of the unit columnar lenses of the lens sheet, seen from the observation side, are non-parallel to the direction of an edge of the display panel.

When any observer receives an image of a scene having the same relative size, shape and location on the retina of each of his two eyes at any instant and the image of the scene has some component of horizontal motion in any direction, the image viewed is three dimensional. If the motion occurs, all scene-object points are spatially located in playback since all of the original ray angles between camera and scene points are reproduced for both eyes by the ray cross-overs at the scene image points. When successive frames are presented, the brain cognizes the motion in linking the frames by persistence of vision. For the brain to perceive an item as moving it must connect these frames, but because of intersecting rays coming from any spatial location in successive frames, the brain cannot connect the frames without also locating the points in space.

A rotary display device comprising one or more vertical arrays of light-emitting diodes (LEDs) are rotated and energized at a controlled rate so as to project a 360 degree floating image. The displayed images are viewable from all angles (i.e., 360 degrees). The LEDs and associated control electronics are rotated at a desired speed, e.g., between about 720 and about 3600 revolutions per minute, by an AC or DC motor. Display content is either pre-loaded to the rotary display or transferred to the rotary display during device operation via a cellular telephone, Wi-Fi, Bluetooth, etc. connection. The electrical power for the system, including the LED array and the control electronics, is provided via a contact-less rotary transformer that functions independently of the rotation speed.

The present invention provides a disc player comprising one or more light sources that project a constant or pulsing light onto the upper portion of a disc being played by the disc player. If a constant light source is used, the a pulsing viewing port for the disc receptacle of the disc player is employed. The pulse frequency, pulse length, pulse period, pulse interval, pulse color, pulse intensity or a combination thereof of the light source or the pulse frequency, pulse length, pulse period, pulse interval, or light transmissivity of the one or more viewing ports can be synchronized with the rotation of the spindle or platen in the disc player, with the optical data stored, or with the rotation of an image precursor on the disc. When the disc is viewed through a viewing port while the disc is being played, a two-dimensional or three-dimensional discrete image is formed by the persistence of vision. The disc player can also include an anti-piracy system to prevent unauthorized playing of digital/optical disc content. The anti-piracy system includes a verification system and access control data. When permission granting information is obtained from the disc, the verification system compares it to the access control data and either allows or disallows the disc player to play the disc.

A camera or camcorder with a multi-view three dimensional (3D) attachment enables acquisition of 3D images and video which are then able to be displayed to a user without the need for specialized glasses. The multi-view 3D attachment captures at least 3 views of the same image from different angles simultaneously on a sensor.

Apparatus for displaying still images to viewers in motion relative to those images, such as passengers on a subway train, includes a plurality of images mounted on a surface, and a slitboard mounted between that surface and the viewer. As the viewers pass by, the slitboard acts like a shutter, creating an animation effect. In addition, there is a stretching or widening effect that enlarges the images, allowing images to be "preshrunk," thereby allowing a large number of images in a small space, increasing the available frame rate of the animation. The stretching effect depends on the distance between the image surface and the slitboard.
