摘要:
The present disclosure provides an optical cloaking device. The optical cloaking device sequentially comprises along an incident direction of an optical path: a first microlens array for imaging, an imaging unit, a display screen, and a second microlens array for projecting content displayed by the display screen to the outside, and further comprises an image processing unit. In addition, there is further provided another optical cloaking device, which comprises: a first microlens array for imaging, a first imaging unit, a first image processing unit, a first display screen, and a second microlens array that are located at a first side, and a third microlens array, a second imaging unit, a second image processing unit, a second display screen, and a fourth microlens array that are located at a second side. The optical cloaking device of the present disclosure has advantages of being capable of adapting to cloaking devices of target objects of different shapes, and displaying an image with a three-dimensional effect, etc.

Means and methods for creating multiple images an a single film frame including a divergent shield member (15) mountable for selective rotation upon a camera lens housing (12) and having means operatively associated therewith for selectively positioning an imager means (16) having multiple openings (38) defined therethrough in complementary relationship to each other so that each opening exposes a different corresponding portion of the film frame while interdicting all other portions of the film frame. The assembly includes locking means (35,36) coactive with detents strategically defined in the imager means to precisely position each opening relative to the field of view of the camera associated therewith.

An exposure control for a pseudo telephoto camera having an objective lens (1) for focusing an image of a subject on a film frame (F) and a manually operated device (9) movable to select a pseudo telephoto field of view reduced from the actual field of view of the objective lens to cover only a portion of the subject, is characterized by comprising a photosensitive element (117) disposed to receive light reflected from the subject to provide a measure of the brightness of the light and a light control (3) responsive to movement of the manually operated device (9) to select the pseudo telephoto field of view for controlling the amount of light reaching the photosensitive element (117) in proportion to the amount of light available to the pseudo telephoto field of view.
摘要:
An apparatus and method that creates visual images of lip movements on film, video tape, or other recorded media. Speech sounds are analyzed, digitally encoded (6) and transmitted to a data memory device (8). Stored within the data memory device (8) is a program for producing output data that creates visual images of lip movements (16) corresponding to the speech sounds. Under control of the data for the speech sounds, the graphical output from the data memory device (8) is sent to a graphic output device and related display equipment (14) to produce the graphical display (16). This display may be combined with the speech sounds so that the resultant audio-visual composite, such as a film strip, contains lip movements corresponding to the speech sounds.
摘要:
@ A photographic print or transparency (1) is displayed by providing eyelets (27) along the edges of a display sheet (3) incorporating the photographic print or transparency and mounting the display sheet under tension within a peripheral frame (4) using springs (29) connected between the eyelets and runners (22) received in a track (21) of the frame. A photographic print may be mounted on a tear-resistant flexible backing sheet (2) to form the display sheet. Transparent tape may be applied to the edges of a photographic transparency to form the display sheet.

L'invention a pour objet un dispositif pour la projection de décors pour la prise de photographies et notamment la réalisation de portraits en studio. Ce dispositif comprend :
- une lentille de Fresnel (3) apte à supporter, sur une de ses faces, un sujet dont l'image projetée doit former le fond décoratif et à recevoir, sur son autre face le faisceau lumineux d'une source lumineuse (4) dont le fonctionnement est synchronisé avec l'appareil photographique (18), - un objectif (5) de même axe principal que la lentille (3) et placé sur le trajet du faisceau lumineux réfracté par celle-ci, - et un miroir (6) placé au-delà de l'objectif (5) par rapport à la lentille (3) et réfléchissant l'image de l'object focalisée par celui-ci dans le champ de l'appareil photographique.
Application à la réalisation de décors pour la prise de photographies.
摘要:
A latent image is formed in a predetermined exposure area of an instant film exposed through an exposure opening formed in a case of a film pack by applying printing light from a print head driven according to image data. While the print head is scanning a linear beam of printing light in a main scanning direction, it moves in a sub-scanning direction perpendicular to the main scanning direction. Considering the clearance between the case and the instant film, the area illuminated by the printing light is wider than the exposure area in both main scanning and sub-scanning direction, and therefore the whole exposure area is exposed to the printing light even if the instant film is displaced in the case. Integrally with a pack load chamber in which the film pack is loaded, a light-shielding housing covering an area including the area where the print head moves is provided.
