  • Patent number: 8687123
    Abstract: A video signal processing apparatus for processing a video signal comprises a receive unit (101, 103, 105) which receives the video signal comprising a sequence of pictures. A processing unit (107) applies a picture noise changing algorithm to the sequence of pictures and a variation unit (113) varies a spatial noise reduction setting for the picture noise changing algorithm between at least some consecutive pictures of the sequence of pictures in response to a predetermined variation rule. Specifically a set of picture manipulation processes (203, 205) with different spatial noise reduction characteristics may be provided and the variation unit (113) may select different picture manipulation processes in consecutive pictures. The approach may introduce high frequency noise flickering which is less perceptible to a viewer thereby reducing the perceived noise.

  • Publication number: 20140043371
    Abstract: A controller for a multi-primary display having M>3 primaries receives a set of input N-primary image color defining values comprising drive values for N primaries for each pixel. A compensator (317) generates a set of compensated N-primary image color (N>=3) defining values by applying a luminance compensation to the values of the set of input N-primary image color defining values where the luminance compensation for each pixel depends on the chromaticity of the pixel. A backlight processor (311) determines backlight levels in response to the compensated N-primary image color defining values. A modifier (313) then generates modified N-primary image color defining values by adjusting the input or the modified N-primary image color defining values or the for the backlight level and a primary converter (315) converts the modified N-primary image color defining values into multi-primary drive values for the display. The approach may e.g.

  • Patent number: 8599313
    Abstract: A device and method for rendering content that includes analyzing previous and/or subsequent temporal portions of a content signal to determine elements that are positionally related to elements of a current portion of the content signal. The current portion of the content signal is rendered on a primary rendering device, such as a television, while the elements that are positionally related to elements of a current portion of the content signal are concurrently rendered on a secondary rendering device. In one embodiment, the elements that are rendered on the secondary rendering device may be rendered at a lower resolution and/or lower frame rate than the rendered current portion of the content signal. In one embodiment, at least one of previous and subsequent temporal portions of a content signal may be analyzed at a lower resolution than the content signal.

  • Patent number: 8325198
    Abstract: An apparatus and method for primary color correction and clipping is provided that is particularly suited for application in mobile displays. It is a combination of a brightness reduction, and a ‘smart’ clipping algorithm and is based on the perceptual attribute “colorfulness”, in which images that are brighter seem to posses more color. In the smart clipping algorithm, a brightness reduction is followed by a gamut (primary) correction and then a smart clip is performed by “adding white” to the out-of-gamut pixels only. This reduces the saturation while it increases the brightness. That is, the saturation is decreased in favor of increased brightness, which gives similar colorfulness on a mobile display as on an EBU display. This smart clipping affects those colors that cannot be represented on the display.

  • Patent number: 8248430
    Abstract: A method converts an input image signal (IS) into a drive signal (DS) for driving sub-pixels (SP) of a display device (DD) comprising display pixels (DPI) having at least two sub-pixel groups (SG1, SG2) being able to contribute to luminance information displayed. The conversion comprises a multi-primary conversion (MPC) which receives the input image signal (IS) and which is performed under a constraint (CO). The constraint (CO) is determined (CD) by substantially matching local display luminances (DL1, DL2; DLD) associated with the at least two sub-pixel groups (SG1, SG2) with corresponding local input luminances (L1, L2; LD) of input pixels (IP) of the input image signal (IS), thereby obtaining a display luminance pattern defined by the display pixels (DPI) corresponding to an input luminance pattern defined by the input pixels (IP) associated with the display pixels (DPI).

  • Publication number: 20120133835
    Abstract: A video signal compensator (10, 70, 80, 290) for selectively compensating for age-related non-uniformities in a display, receives an indication of motion or detects motion in an incoming video signal, and receives or determines an indication of amounts of compensation for the different parts of the display needed to compensate for the non-uniformities. The compensator selectively applies the needed amount of compensation to the video signal according to the indicated motion to apply less of the needed compensation where there is less motion, over at least some of the range of possible motions. This can reduce the drive levels at least where the non uniformities are less visible because of the motion in the video. The reduced drive levels can lead to less ageing and thus prolong display life. The amounts of needed compensation can be predicted or determined from measured outputs of pixels of the display.

  • Publication number: 20120127368
    Abstract: A display control apparatus comprises a video source(105) which provides a video signal comprising frames. The video source (105) is coupled to a compensation processor (107) which filters at least part of a first frame to provide a compensation for perceived motion blur. A display output (109) feeds the compensated video signal to a display (103) which presents the frame. A controller (111) is arranged to control the display (103) such that it radiates light in a sequence of light pulses for each frame where the sequence of light pulses comprising at least some light pulses having different durations. A motion blur processor (113) determines a suitable compensation filter for the perceived motion blur compensation as one that corresponds to an inverse filter of the sequence of light pulses. The use of pulsed light radiation modifies the hold effect filtering such that it can be better and more easily compensated by pre-filtering.

  • Patent number: 8184126
    Abstract: A method of processing image data comprises receiving input signals for specifying red, green and blue colors of the pixels of a display, performing a per-pixel low pass filtering of the input signals, the low pass filtering function being dependent on the chrominance variation between adjacent pixels, and providing the filtered output signals for use in driving the pixels of a display. This method essentially measures the chrominance variation of the incoming signal, in the form of the color change frequency, and depending on this variation, adaptively low-pass filters the incoming signal. This can be in such a way that the chrominance resolution of the outgoing signal is below the maximum chrominance resolution of the intended display, without errors in the average color of a small group of pixels.

  • Publication number: 20110317918
    Abstract: In a method for color enhancement the color distance between spatially close colored pixel or pixel areas does not change more than a threshold, the threshold being a function of the initial color distance. The color difference between pixels that are close together and did not differ much in color will be restricted. This reduces the change on unnatural looking parts of an image and allows more pronounced color enhancement to be 5 used.
