Patent number: 6346965Abstract: A high resolution imaging system for capturing a pair of object fields at extended resolution. The system has a twin input acquisition optical group, an image parting mechanism and a beam reception group where each module works to part and relay images of two object fields. The relayed images are segmented and directed to two image detector systems to extend the acquisition resolution. Electronic processing is used to merge and process the two image detector signals simultaneously. The resolution of the image detector is extended to produce high finesse qualities for high aspect ratio object fields.Type: GrantFiled: December 19, 1997Date of Patent: February 12, 2002Assignee: Agilent Technologies, INCInventor: Peng Seng Toh

Patent number: 6249312Abstract: The video camera comprises a detector having a two-dimensional matrix of photosensitive sites that accumulate charge, the sites being placed in an image plane of an optical system and being connected to a circuit for periodically transferring the accumulated charges at a determined frequency. A deviation member is interposed on the path of light towards the matrix and enables said path to be deflected about a nominal direction. A unit for periodically controlling the deviation means causes the image to be deviated in two dimensions, in a first determined cycle each time through a determined fraction of the pitch step size so as to perform space oversampling, and, in a second cycle, each time through a full pitch step size, which second cycle is a multiple of the first. A processor unit calculates the gain differences and the response offsets between the sites by performing comparisons therebetween.Type: GrantFiled: November 12, 1997Date of Patent: June 19, 2001Assignee: Sagem SAInventor: Michel Broekaert

Patent number: 6233013Abstract: A full-color scanning array uses CMOS active pixel cells, or photogates, as photosensors. A set of photogates, each photogate being specifically filtered for one primary color, is associated with a common node. A clearing gate downstream of the common node applies a relatively high potential to a selected photogate, for the purpose of clearing any charge from the photogate. In this way, the integration time for the photogate can be started at a precise time, and the effective exposure time of each photogate can thereby be precisely controlled. Alternately, one of the set of photogates can be repeatedly cleared without a signal being read therefrom, allowing the array to operate in a monochrome mode.Type: GrantFiled: October 23, 1997Date of Patent: May 15, 2001Assignee: Xerox CorporationInventors: Paul A. Hosier, Jagdish C. Tandon, Scott L. Tewinkle

Patent number: 6208381Abstract: A convertible connector arrangement for a video camera includes first and second connector portions. One of the connectors is configured for analog signals and the other for digital signals. The first and second connectors are joined along one side thereof to be pivotally mounted by a mounting member in an installation body, or frame. The mounting member and the joined connectors are configured such that the two connectors are disposed at a predetermined angle in relation to one another. According to pivotal movement of the mounting member, one of the two connectors may be operably disposed in an opening provided in the installation body. The other connection is thus inoperably stored within the video camera or VTR body. A locking mechanism is further provided to assure secure mounting and operability. A video camera utilizing the convertible connector arrangement may thus be selectably converted for analog or digital operation in a secure and efficient manner.Type: GrantFiled: April 2, 1997Date of Patent: March 27, 2001Assignee: Sony CorporationInventors: Takahiro Fukutani, Hiroyoshi Hamashima

Patent number: 6195127Abstract: A digital camera includes a flash lamp and a CCD imager. A microcomputer first exposes the CCD imager without a light-emission of the flash lamp. Therefore, a luminance evaluation value is calculated by a calculator on the basis of a luminance signal included in a camera signal generated by the CCD imager. The microcomputer succeedingly makes the flash lamp perform a preliminary light-emission, and exposes the CCD imager by {fraction (1/1500)} seconds. The calculator evaluates the luminance evaluation value on the basis of the luminance signal included in the camera signal obtained at this time. Then, the microcomputer calculates a major light-emission amount of the flash lamp on the basis of the two luminance evaluation values obtained in such a manner.Type: GrantFiled: July 16, 1997Date of Patent: February 27, 2001Assignee: Sanyo Electric Co., Ltd.Inventor: Kazuhiko Sugimoto
