Patent number: 7606479Abstract: A digital camera is provided with an emission section which emits independently controlled light to each of multiple emission areas and a light measurement/distance measurement CPU which calculates the amount of light to be emitted at actual emission based on the amount of reflected light of pre-emission and causes the emission section to perform actual emission with the calculated amount of emitted light. The light measurement/distance measurement CPU causes a relatively large amount of light to be emitted to a part of the multiple emission areas in comparison with the other emission areas when pre-emission is performed.Type: GrantFiled: June 26, 2006Date of Patent: October 20, 2009Assignee: FUJIFILM CorporationInventor: Hiroshi Endo

Patent number: 7605861Abstract: A method is described comprising: applying phosphorescent paint to specified regions of a performer's face and/or body; strobing a light source on and off, the light source charging the phosphorescent paint when on; and strobing the shutters of a first plurality of cameras synchronously with the strobing of the light source to capture images of the phosphorescent paint, wherein the shutters are open when the light source is off and the shutters are closed when the light source is open.Type: GrantFiled: March 10, 2005Date of Patent: October 20, 2009Assignee: OnLive, Inc.Inventors: Greg LaSalle, Roger Van der Laan, Stephen G. Periman, John Speck, Timothy S. Cotter, Kenneth A. Pearce

Patent number: 7603031Abstract: A multi-flash photography system provides a dynamically-configurable lighting environment for a single exposure that is created and shaped through the sequentially firing of various light sources with different lighting characteristics controlled in accordance with both a programmed template specifying the flash type, position, firing order, and output intensity, as well as optical processing requirements such as filtering, polarizing, etc., and a shared photometric detector located sufficiently close to the subject being photographed to ensure that the light seen by the detector is substantially the same as the light received at the subject.Type: GrantFiled: June 27, 2005Date of Patent: October 13, 2009Assignee: Canfield Scientific, IncorporatedInventors: George Viaud, Ken Budris, Doug Canfield, Dennis DaSilva, Jim Dornbusch, John Robinson

Publication number: 20090251584Abstract: The invention relates to a camera unit, comprising an image sensor (10), a mechanical shutter (16), a host module (12), and connections between them, in particular a data and control connection (D1, C1) between the image sensor and the host unit. In the image sensor (10), there is a photoelectric pixel matrix (101), a timing unit controlling it, an electronic shutter (ERS), and a ‘global reset’ circuit for resetting the pixels simultaneously. The said data and control connection comprises: a data connection (D1) based on a series bus, a control connection (C1) based on a series bus, and a global-reset signal connection (G1, G2) separate from these. The invention also relates to a method for controlling an image sensor in a camera unit.Type: ApplicationFiled: December 7, 2005Publication date: October 8, 2009Inventor: Juha Alakarhu

Publication number: 20090244351Abstract: An image capture device includes a viewfinder for viewing a subject. The viewfinder either forms an integral part of the device or is an external member that is attachable to, and removable from, the device. The device includes: an optical system; a generating section for capturing an image of the subject through the optical system and generating image data; a detecting section for detecting the degree of focusing of the subject's image represented by the image data; a display section on which the subject's image is presentable based on the image data; and a controller for accepting a decision to use either the display section or the viewfinder for viewing the subject to shoot. If the controller accepts the decision to use the viewfinder, the display section displays no subject's image, and displays information about the degree of focusing of the subject's image for at least a certain period of time. The information has been obtained based on a result of detection done by the detecting section.Type: ApplicationFiled: March 24, 2009Publication date: October 1, 2009Applicant: PANASONIC CORPORATIONInventors: Suguru Takamatsu, Satoko Horio, Akira Yamada

Patent number: 7593056Abstract: A camera and illuminator combination unit has a camera to generate images within a predetermined field of view, the field of view having a central axis, and an illuminator having an illumination axis, the illumination axis being non-parallel with the central axis. Alternately, a camera and illuminator combination unit has a camera to generate images within a predetermined field of view including areas of different distance from the unit and an illuminator having an illumination axis directed towards a distant portion of the field of view.Type: GrantFiled: October 27, 2004Date of Patent: September 22, 2009Assignee: Honeywell International Inc.Inventor: Leonard W.
