Abstract: A 3-dimensional object may contain tunnels passing through the object so that when the object rotates, if the object is viewed from a certain angle, the tunnel is only visible for the moment that the tunnel is pointed directly at the viewer's eye. This system of tunnels can be used to create an animated system of dots when the shape rotates, and the dots can be positioned so that they create the animated illusion of dots moving along the surface of the shape in the opposite of the true direction of rotation.

Abstract: A method for face modeling and related products are provided. The method includes the following. Multiple first images of a face of an object at multiple different angles are obtained when the face rotates, where each first image is obtained at a different angle. Face detection is performed on any first image of the multiple first images, and the any first image is divided into a first face region and a first background region. Multiple depth images corresponding to the multiple first images are obtained and each of the multiple depth images is segmented according to the first face region and the first background region to obtain multiple face region images. Three-dimensional (3D) face modeling is performed according to the multiple face region images to obtain a 3D face image.

Abstract: A non-limiting example game system comprises a processor incorporated in a main body apparatus, and the processor displays, in a battle scene, a battle screen including a player character, an enemy character and a board face object on a display. The board face object having a circular board face that is formed with multiple partial objects that are sectioned by multiple concentric circles and multiple lines extended radially. A player makes the multiple partial objects move in a circumferential direction or a radial direction so as to change arrangement of multiple enemy characters placed on the multiple partial objects, thereby causing the player character to perform an attack.

Abstract: A system encourages experimentation with audio frequency and speaker technologies while causing an inanimate object to appear to lip-sync. The system applies a bandpass filter to an incoming audio stream to determine a magnitude of audio content in a frequency band of interest. For example, the system may filter results directed at the voice band, associated with speech. A controller controls a strobe light to flash at a particular point of travel of a platform reciprocating at a known frequency. An illusion is created that a sculpture, such as a piece of paper formed into a ring, is lip-synching to music.

Abstract: An animation device for producing the perception of animation within a slotted cylinder. The animation device has a rotatable platform, and a slotted cylinder with wall segments at least partially separated by longitudinal slots retained to rotate concentrically with the platform. Images, such as two-dimensional or three-dimensional figures, are retained to rotate with the platform along a circumference substantially concentric with but greater than the circumference of the slotted cylinder whereby the slotted cylinder is disposed radially inward of the images. The images, which can be sequential, could be retained by elongate support members, by an image cylinder, or by any other support. When the platform is rotated, an observer looking through the slots in the slotted cylinder can perceive an animation of the plurality of images within the slotted cylinder. Multiple, separate pluralities of images can be retained, potentially along different circumferences, to produce distinct animations.

Abstract: A method and apparatus for displaying motion pictures. In one embodiment, a cylindrical body with vertical facets ringed by a series of motion-picture images within or around the cylinder (that independently turn within or around the cylinder). When the images spin within or around the substantially fixed cylinder, to the viewer looking through the cylinder's faceted field, the background images pass (or “flip”) through two or more of the cylinder's facets, producing a “shutter-like” effect, such that each image is replaced by an adjacent one of the series of motion-picture images (to produce an animated effect).

Abstract: A method and apparatus for displaying motion pictures. In one embodiment, a cylindrical body with vertical facets and then a motion picture image affixed to each facet (creating a series). In this embodiment, the images are substantially flat against a glossy background, and there is a reflected light source cast upon them. When the cylindrical body is rotated about its longitudinal axis, to the viewer, a reflection of the images “hovers” just above the underlying images, and the spinning (or “flipping”) of the facets produces a “shutter-like” effect, such that each reflected image is replaced by an adjacent one of the series of motion-picture images (to produce a magical animated effect).

Abstract: A method of combining a series of inanimate three dimensional objects(2), a rotational surface (4), and a strobe light(8) in order to achieve the illusion of animation. In the present invention a plurality of objects(2) are demountably fixed, in cyclical order, to a rotational surface(4), each within its own staging area(6). Each successive object(2) is subtly different in shape, size, color or pose to that of the prior object(2) in the sequence. A strobe light(8) is disposed facing the objects(2) as they revolve on the rotational surface(4). The strobe light(8) pulses with consistent periodicity so as to act like a visual shutter. This causes a pulsing illumination of the objects(2) as they cycle on the rotational surface(4). To achieve the optimum effect of animation, the rate of pulse should be one flash of light per object(2) as it traverses through each stationary staging area(6). Due to the persistence of vision, the illusory appearance of sustained movement is achieved.

Abstract: A method and an apparatus for displaying motion pictures. In one embodiment, a substantially transparent and faceted cylindrical body includes a series of motion picture images imprinted on each one of the facets of the cylindrical body. When the cylindrical body is rotated about the longitudinal axis of the cylindrical body, the images on the opposite side of the cylindrical body to a viewer are observed through the interior of the cylindrical body through the facets of the cylindrical body near the viewer. When the cylindrical body is rotated about its longitudinal axis, the facets of the cylindrical body wipe across in front of the images behind the facets on the opposite side of the cylindrical body such that each image is dissolved into a neighboring or an adjacent one of the series of motion picture images to produce an animated effect.

Abstract: A device for displaying an animated motion picture in which an elongated web of material is provided for receiving images in predetermined, spaced relation. The web may be supported in wound configuration on a reel, and the predetermined, spaced relation of the images is such that the images line up substantially behind one another when the web is wound on the reel. The web has a trailing end disposed at the radially inward end of the winding and a leading end which is disposed at the radially outward end of the winding. The reel is supportable in a generally horizontal orientation to allow unwinding of the web from the reel in a controlled, downward spiral under the influence of gravity, upon release of the leading end of the web, to display the images in rapid succession to present an animated motion picture to a viewer.
