20100020109 | DYNAMIC GAMUT CONTROL - A method of dynamic gamut control comprises the step of controlling (LD) intensities of at least a subset (PR, PG, PB) of a set of color primaries (PR, PG, PB, PW) associated with corresponding sub-pixels (RP, GP, BP, WP) of a display device. The method further comprises the step of searching (PC) for a minimal intensity value (Ra; Ga; Ba) of one of the color primaries of the subset (PR; PG; PB) being adjusted, to obtain together with the other color primaries (WP) of the set of color primaries (PR, PG, PB, PW) an adjusted color gamut (GG | 01-28-2010 |
20110019083 | Frame-Rate Conversion - 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. | 01-27-2011 |
20120062787 | CAMERA, SYSTEM COMPRISING A CAMERA, METHOD OF OPERATING A CAMERA AND METHOD FOR DECONVOLUTING A RECORDED IMAGE - 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. | 03-15-2012 |

20120194578 | DYNAMIC GAMUT CONTROL - 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. | 08-02-2012 |
