Patent number: 6646735Abstract: A surface inspection apparatus determines an optimal apparatus condition setting at which a pattern layer is to be inspected based upon images of a test piece captured by an image-capturing device while irradiating illuminating light onto the surface of the test piece and varying an apparatus condition at which the images are captured. An optimal apparatus condition setting is determined by using images obtained before forming an uppermost pattern layer, an optimal apparatus condition setting is determined by using images obtained after the formation of the uppermost pattern layer and it is judged as to whether or not an image captured by the image-capturing device originates from the uppermost pattern based upon the plurality of optimal settings thus is ascertained.Type: GrantFiled: September 12, 2001Date of Patent: November 11, 2003Assignee: Nikon CorporationInventors: Kazuhiko Fukazawa, Mari Yamamoto, Takeo Oomori

Patent number: 6647207Abstract: A parallax compensation system and method is provided for a camera including an independent viewfinder. For close focus pictures, the camera's taking lens is shifted towards the viewfinder. In one embodiment, for far focus pictures the camera's taking lens is moved away from the viewfinder and is not centered on the image recording medium axis. The lens shifting is accomplished by mounting the taking lens eccentrically in a lens barrel. Rotation of the lens barrel shifts the taking lens towards the independent viewfinder for close focus shots. In one embodiment, the viewfinder axis is tilted towards the taking lens to help eliminate parallax in close focus pictures.Type: GrantFiled: January 23, 2002Date of Patent: November 11, 2003Assignee: Concord Camera Corp.Inventor: Wilfried Bittner

Patent number: 6646737Abstract: A calibration standard which may be used to calibrate lateral dimensional measurement systems is provided. The calibration standard may include a first substrate spaced from a second substrate. In addition, the calibration standard may include at least one layer disposed between the first and second substrates. The layer may have a traceably measured thickness. For example, a thickness of the layer may be traceably measured using any measurement technique in which a measurement system may be calibrated with a standard reference material traceable to a national testing authority. The calibration standard may be cross-sectioned in a direction substantially perpendicular to an upper surface of the first substrate. The cross-sectioned portion of the calibration standard may form a viewing surface of the calibration standard. In this manner, a lateral dimensional artifact of the calibration standard may include the traceably measured thickness of at least the one layer.Type: GrantFiled: September 24, 2001Date of Patent: November 11, 2003Assignee: KLA-Tencor TechnologiesInventors: Marco Tortonese, Ian Smith, Ellen Laird, Bradley W.

Patent number: 6646800Abstract: A visual and audio system for theaters includes a spherical screen having a desired radius of curvature while having a surface reflectivity of 5-50%, and a projector located at a focal point of the spherical screen. The curvature radius of the spherical screen corresponds to the projection distance of the projector. The image projected from the projector at the focal point of the spherical screen is reflected from the spherical screen in a horizontal direction. Accordingly, viewers can view images projected on the screen corresponding to 5-50 time the brightness of images viewed on conventional theaters screens. Central speakers are arranged at the focal point of the spherical screen, so that viewers perceive the sound effect as coming directly from the spherical screen. This visual and audio system can be effectively used in theaters for stereoscopic moves, theaters for high resolution images, and theaters for viewing of images at a higher brightness such as sports arenas, and restaurant theaters, etc.Type: GrantFiled: July 18, 2002Date of Patent: November 11, 2003Inventor: Hae-Yong Choi

Patent number: 6640058Abstract: A camera is provided which has a back cover for opening and closing an aperture, a spool chamber and a cassette chamber. A battery chamber for housing a battery is disposed on a supporting shaft side of the back cover, and the aforementioned battery chamber is present obliquely behind the cassette chamber inside the camera when the back cover is in a closed state. A part of the battery chamber protrudes from the back face of the back cover. Therefore, the exterior shape of the camera can be miniaturized and downsized without hindering loading of a film cassette. Further, since the battery chamber portion protruding from the back cover can be made to function as a grip portion of the camera, a camera superior in portability and favorable in holdability is provided.Type: GrantFiled: April 18, 2002Date of Patent: October 28, 2003Assignee: Olympus Optical Co., Ltd.Inventors: Yoshihiro Yokomae, Toshifumi Nakano

Patent number: 6616281Abstract: A video signal is generated representative of a background scene, such as a weather map, which provides an outline of all the detail in the map. This outline detail is made visible to a foreground subject by projecting it onto a white screen behind the subject in a selected color such as green. The projector is selectively inhibited so as to prevent the background detail from projecting onto the foreground subject. The white screen and the green detail lines are removed and replaced by the background scene by an image compositing process. Prompts are visible to the foreground subject, but not visible to a home viewing audience.Type: GrantFiled: August 7, 2002Date of Patent: September 9, 2003Assignee: iMatte, Inc.Inventors: Paul Vlahos, Petro Vlahos

Patent number: 6091908Abstract: A photographic device eliminates photometric errors that occur in photometry, obtains a more accurate exposure, and shortens the time required for photometry. The device includes an orientation position detector and photographic mode setter, which outputs photographic conditions based on a set photographic mode. A photometer divides the subject field into multiple regions and analyzes the light. An exposure calculator calculates the exposure value based on the output of the photometer. A memory stores weighing coefficients corresponding to multiple light brightness patterns. A tilt switch position orientation detector determines the position of the camera. A selector selects the weighing coefficients from the memory, based on the photographic mode setting component output and the position of the camera. A frequency analyzer then analyzes the output frequency of the photometer. A re-calculator re-calculates the exposure value based on the result of the frequency analyzer and the selection of the selector.Type: GrantFiled: June 4, 1997Date of Patent: July 18, 2000Assignee: Nikon CorporationInventor: Hiroyuki Fukuda
