A method for producing a security element formed as a lenticular flip, including a micro-optical layer, a carrier substrate and an image layer, wherein the image layer includes n images for n=1 to i which are visible from an n-th observation angle allocated to the n-th image, and wherein n is at least 1. The images are imaged on a photoresist with parallel light in contact print or by means of projection. After the photoresist is developed, an image layer which includes the i images is present.

An optical device includes: a light guide plate having a group of optical-path deflectors configured to change the optical path of light from a first light source to form an image in the space within a first angle range, and change the optical path of light from a second light source to form an image in the space within a second angle range, wherein the first angle range and the second angle range are separated from each other or adjoining each other.

A time delay error occurring in the case of acquiring two holograms (object hologram and reference hologram) necessary for reconstruction in the related art or in the case of acquiring four physical holograms having different phase shift degrees may be removed. DC noise (including background noise) may be completely removed by using a software-implemented phase shifting method.

A decorative member that is a three-dimensional modeled article comprises a sheet, a lens part, and an image-forming part. The sheet has a light-transmitting property and has a first sheet surface formed as a curved surface. The lens part is provided so as to curve along the first sheet surface. The lens part comprises a plurality of protruding lenses disposed in parallel. The image-forming part comprises an image having a main axis direction. An angle formed between the main axis direction and an extension direction that is a longitudinal direction of the lenses is 040 or 5090. The curved surface has a first region to a third region having different normal directions and has a shape in which one of the normal directions of the respective regions is inclined with respect to a plane including the other two normal directions.

The curved surface has a first region to a third region having different normal directions and has a shape in which one of the normal directions of the respective regions is inclined with respect to a plane including the other two normal directions.

An image projection system may include a translucent or transparent projection screen and multiple lenticules disposed on or within the projection screen. The image projection system may also include a projector to project multiple images onto the projection screen. The images may include multiple views of a scene, and the projector may simultaneously project the images to generate a three-dimensional display of the scene.

A display device comprises a projection device projecting a display image, an aerial imaging element, and a distribution mechanism in which distribution units are arranged at a given interval. An interval between the distribution units is determined according to a relationship between a number of view point pixels constituting a pixel unit, a number of pixel units, a distance from the pixel unit at a center to the pixel unit at an edge, a distance from a distribution unit at a center to the distribution unit at an edge, a pitch of the view point pixel, an angle of light from the pixel unit at the center emitted to the distribution unit, and an angle of the emitted light, an angle of light from the pixel unit at the edge emitted to the distribution unit, and an angle of the emitted light, a distance between the projection device and the distribution units, a refractive index of the distribution mechanism, a distance between the real image and an optimal viewing position for a viewer, and a projection width.

A mobile device has at least two camera lenses for taking a first image and a second image as a stereo-image pair. The mobile device also has an electronic processor for composing a composite image from first image strips compressed from the first image and second image strips compressed from the second image in an interlaced manner. The composite image is conveyed to a display panel so that a viewer can see a 3D image through a parallax separating sheet with parallax separating units. The composite image can also be electronically shifted by haft an image strip to accommodate a viewer with a dominant eye. The shifting can be initiated by a viewer using a switch on the mobile device.
