Patent number: 8471841Abstract: A compact flat panel color calibration system includes a lens prism optic able to pass a narrow, perpendicular, and uniform cone angle of incoming light to a spectrally non-selective photodetector. The calibration system also includes a microprocessor operable to determine the luminance of the display based upon the information gathered by the photodetector. A software module included in the calibration system is then operable to process the luminance information in order to adjust the flat panel display.Type: GrantFiled: May 11, 2012Date of Patent: June 25, 2013Assignee: RPX CorporationInventors: Daniel Evanicky, Ed Granger, Joel Ingulsrud, Alice T.

Publication number: 20110188134Abstract: A method of controlling a point spread of an object is disclosed. The method includes determining a first value of a characteristic of an optical component of a display, wherein the display includes a first display screen and a second display screen, and wherein the first and second display screens overlap. The method also includes determining a position for the optical component based upon the first value of the characteristic by determining a distance from an origin of the object to the position based upon the first value of the characteristic.Type: ApplicationFiled: April 22, 2010Publication date: August 4, 2011Applicant: PURE DEPTH LIMITEDInventors: Gareth Paul Bell, Gabriel Damon Engel, Mark John Searle, Daniel Evanicky

Patent number: 7742239Abstract: A method of controlling the point spread function of an image projected with said image being diffused by a filter; said point spread function is a result of the application of spatial filter(s) on said image; with said control of the point spread function effected by varying the distance between such image and said spatial filter(s) and varying the bidirectional scattering transmission function of the spatial filter(s). Said spatial filter may be a holographic diffuser, which by method of manufacture has a well defined bi-directional scattering transmission spread function. Control of said spread function is particularly useful to maintain image quality while abating moiré interference in situations where two periodic patterns are layered causing moiré interference.Type: GrantFiled: March 17, 2003Date of Patent: June 22, 2010Assignee: PureDepth LimitedInventors: Gareth Paul Bell, Gabriel Daemon Engel, Mark John Searle, Daniel Evanicky

Publication number: 20070085816Abstract: A system and method are described herein for controlling the white balance and providing gamma correction without compromising gray-scale dynamic range in a flat panel liquid crystal display (LCD). According to one embodiment of the present invention, the flat panel LCD includes electronic circuitry for coupling to a host computer to receive a white-balance adjustment control signal, and electronic circuitry for receiving image data to be rendered on the flat panel LCD. Further, the flat panel LCD of one embodiment is configured for coupling to a color-sensing device to receive optical characteristics data of the flat panel LCD detected by the color-sensing device. The white balance adjustment mechanisms include the provision of two or more light sources of differing color temperature, whose brightness can be independently varied (and distributed through a light distribution mechanism) to adjust color temperature without altering the grayscale resolution of the RGB colors.Type: ApplicationFiled: November 14, 2006Publication date: April 19, 2007Applicant: Silicon Graphics, Inc.Inventors: Daniel Evanicky, Oscar Medina
