Abstract:
본 발명에 따른 시선 결합장치는 피사체에서 발산되는 빛이 소정의 방향을 가지고 입력되는 입력부와, 상기 입력부에서 입력된 빛을 받아 소정의 방향으로 내보내는 내보내는 출력부와, 상기 피사체에서 발산되어 상기 입력부로 입력된 빛이 상기 소정의 방향과 일치되어 상기 피사체를 관측하는 관측자에게 전달되도록 상기 입력부에 입력된 빛을 상기 출력부로 전달하는 연결부를 구비한다. 따라서 가시광선 영역에서 불투명물체가 관측자의 눈에 투명하게 보이게 하거나, 출력부를 통해 피사체를 임장감(臨場感) 있게 출력할 수 있는 장점을 가진다.
Abstract:
High Dynamic Range (HDR) spherical images can be obtained without a requirement for special purpose cameras having linear optical sensors. Various examples of the present invention can use a standard single lens reflex (SLR) camera with a fisheye lens to obtain spherical images. The camera is positioned to obtain a plurality of images at different exposures with the camera facing up and again with the camera facing down. The images may then be processed to obtain an HDR spherical image. A center post of a tripod, an offset arm and a rotational mount may be used to position the camera. The offset arm and rotational mount can enable the camera to be oriented straight up or straight down along an optical axis separated from the center post of the tripod.
Abstract:
A method for measuring the timing of a flash event including capturing a first image prior to the commencement of a flash event. Capturing a second image during the occurrence of the flash event, and comparing the second image to the first image to determine a time related characteristic of the flash event.
Abstract:
Methods for producing photographic slides having specified transmission functions are provided in which an image on a computer screen is iteratively adjusted so that a photographic image of the screen when developed has the desired transmission function to within a user-specified criterion. Photographic slides suitable for use in determining a three dimensional configuration of an object, e.g., a patient's tooth, are also disclosed.
Abstract:
. L'invention concerne une installation de prise de vue comprenant une zone d'observation (ZO), une caméra (CAM), un écran (ECR) les séparant, un premier flux lumineux (FL1) acheminant des images depuis l'écran vers la zone d'observation, un deuxième flux lumineux (FL2) acheminant des images de la zone d'observation vers la caméra, ces deux flux lumineux (FL1, FL2) traversant une surface commune (K) de l'espace partagée entre ces flux sur une base temporelle. Selon l'invention, un projecteur (PRJ) émet un troisième flux lumineux (FL3) en direction de l'écran (ECR), lequel est partagé en deux fractions de surface (ECR1, ECR2) complémentaires respectivement allouées à la rétrodiffusion du troisième flux et à la transmission du deuxième flux, et chacune des fractions de surface (ECR1, ECR2) se modifie dans le temps de manière que chaque portion de l'écran soit alternativement transparente et rétro-diffusante.
Abstract:
A vehicle (10) includes an infrared imaging system (11). The system includes an infrared camera (12) positioned in the center of the front grille of the vehicle. The infrared camera includes a window (13) that has a holographic fringe pattern (14) which cooperates with visible light rays (27, 47, 52, 57) to generate an image (29) that is visible at a location spaced from the vehicle. The visible image may, for example, be a trademark or other symbol identifying the manufacturer of the vehicle. Infrared radiation (31) passes through the element and the structure thereof without significant change, and is detected by an infrared detector (33). A visible image corresponding to the infrared radiation is ultimately displayed by a head up display (19) on a portion (16) of the vehicle windshield (17).
Abstract:
A method of printing digital data onto or with a photograph using infra-red ink and using an ink jet printing process is disclosed. The data can store the details of the image in an encoded fault tolerant form enabling the copying or recovery of the photograph notwithstanding damage thereto.
Abstract:
A camera case and film cartridge system (40) that can be used with captioned film (i.e., film that has a pre-exposed caption such as "Happy Birthday" or "It's a Boy" on each film frame such that when the remainder of the film frame is exposed with the camera in the normal course, the each resulting picture will include the caption) in which the film cartridge (40) is designed and constructed to use the standard 35mm film cannister (50) (or any other standard film cannister) so that the film, once exposed in the normal course, can be developed at any retail or commercial developing facility that is equipped to handle the standard film cannister (50). The film cartridge (40) includes a diffuser (58) that partially shields the pre-exposed, captioned portion of the film from further exposure. Because the diffuser (58) is incorporated into the film cartridge instead of the camera case, the same camera can be used with different captioned formats.
Abstract:
An infrared optical system for an infrared camera comprises a support member for holding a convex lens composed of low-dispersion material that transmits infrared rays. A diaphragm for controlling the light entering the convex lens is arranged in front of the convex lens. An aberration corrector for decreasing spherical aberration is provided near the diaphragm. In addition, behind the convex lens is arranged a plate for field smoothing, whose thickness varies with the height of the image so that the curvature of field can be canceled.
Abstract:
A camera (10) for partially preexposed, multiple exposure film (12) including a body with an exposure well (24) and a film track across the well. A lens (26) is attached to the camera body at the other end of the exposure well. A mask (40) which includes a plate (42) and a substantially perpendicular flange (44) is positioned at the back of the exposure well adjacent to the film track. The flange extends into the exposure well and is adhered to the wall thereof. The plate includes margins to overlap the body of the camera about three sides around the exposure well. Another camera includes an asymmetrically arranged exposure well (50) relative to the film track such that the body of the camera about the exposure well extends to cover the preexposed image segment on a multiple exposure film strip.
