Patent number: 9606450Abstract: An image projection apparatus comprises a light projector (605) which projects an image onto a surface (603) of an object. A focussing processor (609) is arranged to focus the image on an image plane (607) and a controller (611) dynamically varies the position of the image plane (607) relative to the surface (603). The movement may be a predetermined periodic movement and the surface may specifically be a non-planar surface. The movement may result in a blurring effect independent of distance, and may specifically provide a blurring effect that can be pre-compensated by pre-filtering of the image to be projected. The invention may allow improved quality of a projected image, such as e.g. of an image projected on a non-planar or moving surface.Type: GrantFiled: January 3, 2011Date of Patent: March 28, 2017Assignee: KONINKLIJKE PHILIPS N.V.Inventor: Dmitry Nikolaevich Znamenskiy

Patent number: 9147362Abstract: A method of dynamic of gamut control is provided for a display having a multi-spectral (typically multi-color) backlight, and sub-pixels corresponding to the different backlight spectra and at least one common sub-pixel. The display may f be an RGBW display having an RGB backlight. The method includes iteratively calculating the minimum required backlight intensities that will allow all (selected) color points of an image to be represented by the display. The determination for a light source of the backlight is based on determinations of intensities determined for other light sources in a previous iteration.Type: GrantFiled: October 8, 2010Date of Patent: September 29, 2015Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Dmitry Nikolaevich Znamenskiy, Oleg Belik, Karel Johannes Gerhardus Hinnen

Patent number: 9131221Abstract: A camera and camera system is provided with an optical device (8). The optical device creates simultaneously two or more images of object on a sensor (4) forming a compound image. The distance d between the constituting images of objects in the compound image is dependent on the distance Z to the camera. The compound image is analyzed (9), e.g. deconvolved to determine the distances d between the double images. These distances are then converted into a depth map (10).Type: GrantFiled: June 21, 2010Date of Patent: September 8, 2015Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Ruud Vlutters, Frederik Jan De Bruijn, Dmitry Nikolaevich Znamenskiy

Patent number: 8842742Abstract: A method of generating presentation time stamps, PTSs, for motion-compensated frame-rate conversion of a sequence of frames. In one aspect, the method comprises for each new frame: determining an average difference between the capture time-stamps of recent consecutive new frames; and generating the PTS based on the capture time-stamp of a previous new frame and the average difference. In another aspect, the method comprises detecting a first cadence and a second different cadence in the sequence of frames; and generating a PTS for each new frame defined by the first cadence, such that in each case the difference between the PTSs of consecutive new frames is intermediate between the true interval between those frames according to the first cadence and the true interval between them according to the second cadence.Type: GrantFiled: July 16, 2010Date of Patent: September 23, 2014Assignee: Entropic Communications, Inc.Inventors: Claus Nico Cordes, Dmitry Nikolaevich Znamenskiy

Patent number: 8605202Abstract: A camera and system comprising a camera in which, during exposure, the ratio of the distance between the lens and the sensor and the focal length is changed. The rate of change is set such that motion invariant imaging is achievable for practical speed ranges, i.e. speed of up to at least 5 km/hour at 2 meter distance of the lens, by deconvoluting the compound image. Preferably the achievable speed range is at least twice as high. A linear motion of the sensor is preferred.Type: GrantFiled: April 28, 2010Date of Patent: December 10, 2013Assignee: Koninklijke Philips N.V.Inventors: Remco Theodorus Johannes Muijs, Dmitry Nikolaevich Znamenskiy, Harold Agnes Wilhelmus Schmeitz, Ruud Vlutters, Franciscus Hendrikus Van Heesch

Patent number: 8390643Abstract: A method of dynamic gamut control is disclosed. In accordance with a first aspect of the invention, control of the intensities of a set of color primaries illuminating associated sub-pixels of a display device is disclosed. Thus, the intensities of the light sources are controlled to control the intensities of the color primaries after the color filters. The method searches for a minimal intensity value of one color primary, which is adjusted to obtain together with the other color primaries of the set of color primaries an adjusted color gamut still containing all the colors of the set of colors.Type: GrantFiled: September 14, 2007Date of Patent: March 5, 2013Assignee: Koninklijke Philips Electronics N.V.Inventors: Oleg Belik, Dmitry Nikolaevich Znamenskiy

Publication number: 20120194578Abstract: A method of dynamic gamut control is provided for a display having a multi-spectral (typically multi-color) backlight, and sub-pixels corresponding to the different backlight spectra and at least one common sub-pixel. The display may for example be an RGBW display having an RGB backlight. The method comprises iteratively calculating the minimum required backlight intensities that will allow all (selected) color points of an image to be represented by the display. The determination for a light source of the backlight is based on determinations of intensities determined for other light sources in a previous iteration. In some embodiments, the approach allows for a clipping of a number of the color points. The invention may reduce power consumption while maintaining a high image quality and can be implemented computationally very efficiently.Type: ApplicationFiled: October 8, 2010Publication date: August 2, 2012Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Dmitry Nikolaevich Znamenskiy, Oleg Belik, Karel Gerhardus Hinnen
