The two slide blocks are slidably movable relative to the slide rail toward or away from each other to change the distance between the two lens barrels of the optical device. The blocking member is manually operable to provide an acting force between the slide block and the slide rail, and thus changing the friction force therebetween during sliding movement of the slide block. In this way, undesired sliding movement of the slide block relative to the slide rail can be prevented.Type: GrantFiled: March 7, 2006Date of Patent: January 1, 2008Assignee: Asia Optical Co., Inc.Inventors: Pai Shih-Yu, Lai Hsiang-Yi

Patent number: 7177080Abstract: A viewing arrangement includes an image generator having a single, two-sided display screen having a front and a back side which display a front image and a back image, respectively, of a translucent or transparent image generated by the image generator; two eyepieces suitable for viewing the front and back images via respective eyes of a person using the arrangement; and an optical imaging system which images and transmits the front image to one eye of the person using the arrangement via the first eyepiece, and the back image to another eye of the person using the arrangement via the second eyepiece. A corresponding method includes generating an image; processing the image with an optical imaging system into front and back images; displaying the front and back images on a two-sided display; and transmitting the front and back images to first and second eyepieces.Type: GrantFiled: September 7, 2004Date of Patent: February 13, 2007Assignee: Flir Systems ABInventor: Michel Soderlindh

Patent number: 7072107Abstract: A modular binocular-like vision assembly (300) has individual interconnecting inner (320, 330) and outer (310, 340) optical modules. Each module is separately sealed and self-contained and includes image intensifier means for converting incoming light to an intensified visible image for presentation to the eyes of the observer in low light conditions. Electrical connectors are provided between the modules for permitting free flow of electrical power and information between the modules. Attaching system is provided for removably attaching the outer modules to the inner modules to deliver a panoramic field of vision and removal of any single module from the assembly will not break any pressure seals or degrade the optical performance of the removed module or the remaining modules.Type: GrantFiled: September 14, 2001Date of Patent: July 4, 2006Assignees: Night Vision Corporation, Kollsman, Inc.Inventors: Danny Filipovich, Jack C. Fiore, Ofer Robert Ziv, Philip Uy

Patent number: 6961150Abstract: An image processing apparatus includes an edge detecting unit which identifies an area of given image data as a gradation sequence area and a character/line art area and which outputs edge information of the character/line art, a level converting unit which generates a strength modulation signal so as to emphasize an edge of the character/line art area, a laser driver which outputs a laser drive signal in order to form a picture dot larger than a standard size in response to the strength modulation signal. Further, according to the present invention, it is possible to print an image with emphasizing an edge portion of a character/line art by a laser printer.Type: GrantFiled: September 19, 2001Date of Patent: November 1, 2005Assignees: Kabushiki Kaisha Toshiba, Toshiba Tec Kabushiki KaishaInventor: Hiroyuki Okuyama

Publication number: 20040257648Abstract: Electronic binoculars comprise an imaging unit, and first and second ocular units. The imaging unit has an imaging device that projects an optical image of an object, and converts the optical image to electric signals. The first ocular unit has a first image-indicating device that indicates the object image based on the electric signals in a first image-indicating field. The second ocular unit has a second image-indicating device that indicates the object image based on the electric signals in a second image-indicating field. The first image-indicating field is smaller than a first effective image-indicating area which is the maximum image-indicating area of the first image-indicating device. The second image-indicating field is smaller than a second effective image-indicating area which is the maximum image-indicating area of the second image-indicating device. The respective first and second image-indicating fields can move within the respective first and second effective image-indicating areas.Type: ApplicationFiled: June 17, 2004Publication date: December 23, 2004Applicant: PENTAX CorporationInventor: Makoto Mogamiya

Patent number: 6827577Abstract: The night vision goggle training apparatus simulates the size, feel and handling of actual night vision goggles. A narrow band-width green filter is positioned over the viewing port, to simulate nighttime viewing conditions. The image intensification system used in night vision goggles is eliminated; limiting use of the training goggles to daytime use. The out of balance weight of the night vision goggles is identical to actual night vision goggles. Brightness control is simulated by attenuation filters that fit over the objective lens. The blooming effect of lights is simulated with a star filter. A thin, fine mesh screen is used to simulate reduced acuity, scintillation and ghosting effects during low light or rapid motion, which occur during use of actual night vision goggles. The objective focus and diopter adjustment are identical to night vision goggles.Type: GrantFiled: August 14, 2002Date of Patent: December 7, 2004Assignee: DCS CorporationInventor: Jim E. Fulbrook

Publication number: 20040227993Abstract: The invention relates to a binocular image display system which can follow changes in the viewing position of a viewer, if any, without superposition of the right-eye pupil and the left-eye pupil, so that the viewer can view 3D images, etc. The image display system comprises an image display device 3, an illumination light source 4, an illumination optical system, a relay optical system 31 and an eyepiece optical system 32. The image display device 3 is a single device adapted to display left-eye and right-eye images alternately. The illumination light source 4 comprises a light source that is changed over to separate illumination areas depending on the displayed left-eye and right-eye images so that the illumination areas can be moved. The exit pupil comprises a pair of left and right exit pupils 1L and 1R determined depending on the illumination areas of the illumination light source.Type: ApplicationFiled: May 13, 2003Publication date: November 18, 2004Inventors: Takahiro Amanai, Takayoshi Togino
