Abstract:
Beschrieben wird ein Verfahren zur Erzeugung einer Videobildfolge mit hohem Dynamikbereich, das umfasst: Erzeugen von mehreren Bildsequenzen, die jeweils mindestens ein Bild aufweisen; und Erzeugen jeweils wenigstens eines Bildes aus den einzelnen Bildern einer Bildsequenz; wobei vor Erzeugen der Bilder einer ersten Bildsequenz Bewegung in wenigstens einer zeitlich vorangehenden zweiten Bildsequenz ausgewertet und ein Bewegungswert ermittelt wird, und wobei die Belichtungen der einzelnen Bilder der ersten Bildsequenz und/oder die Anzahl der Bilder der ersten Bildsequenz abhängig von dem Bewegungswert eingestellt werden.
Abstract:
Systems and methods of processing pixel information associated with video image deinterlacing are disclosed. In one exemplary implementation, the method may include performing an edge adaptive interpolation process on a present field so as to determine whether an edge passes through a pixel, wherein the edge adaptive interpolation process provides edge data including a first intensity estimate for the pixel, receiving motion data associated with motion compensation processing, including an estimated motion vector for at least one pixel proximate to the pixel in at least one reference field, determining a second intensity estimate for the pixel as a function of the edge data and the motion data, and performing an intensity- calculation procedure, wherein an interpolated intensity of the pixel is calculated as a function of the first intensity estimate and the second intensity estimate.
Abstract:
A method and system is provided for reducing mosquito noise in a digital image. The method and system receives an input luminance value for a first pixel in the digital image, and determines whether the first pixel is in relative close proximity to an object appearing in the digital image, based on a comparison of the variation between the input luminance value for the first pixel and luminance values of a first plurality of neighboring pixels. If the first pixel is in relative close proximity to an object, the method performs an average filtering of the input luminance value for the first pixel, based on the luminance values of a second plurality of neighboring pixels, to provide a filtered luminance value for the first pixel.
Abstract:
A method for generating control signals particularly based on a movement or a pose of a at least one viewer comprising; detecting a plurality of images of a scene illuminated by ambient light and the light generated by the display device, wherein each of the plurality of images comprise a substantially constant amount of ambient light and a pre-determined amount of light generated by the display device and wherein the pre-determined amount of light varies between at least two consecutive images of the plurality of images; separating display generated light from the ambient light by using known indicia of the display device generated light to extract only a portion of the illuminated scene; and generating a control signal in response to the extracted portion.
Abstract:
Memory systems are disclosed which are comprised of a two or dual layer printed circuit board. Attached to the top layer of the dual layer printed circuit board are a memory chip and a memory controller with aligned, optimistic pin outs that optimized signal integrity layouts between certain high speed pins in a single layer. A set of high speed lines, including the data lines, that do not include any vias connect certain of the pins of the memory controller to certain of the pins of the memory chip. The high speed lines are covered by a sub-PCB that includes a copper lay that extends a ground or electrical plane above the top layer of the dual layer printed circuit board.
Abstract:
A method and system for frame insertion in a digital display system is provided. The method is adapted for use with a liquid crystal display (LCD) type display and is effective to substantially reduce motion blur. The LCD display receives a sequence of digitized input frames at a first frequency. The method generates a sequence of output frames that include the digitized input frames interspersed with a plurality of modified frames. Each of the modified frames is substantially similar to a preceding digitized input frame, but has a reduced luminance. The modified frames may be generated by multiplying a preceding digitized input frame by a reduced luminance factor. The reduced luminance factor may be determined as a fixed value or as a function of an average pixel level of a preceding frame.
