  • Patent number: 10742925
    Abstract: A smart multimedia content receiver automatically resizes video images based on the content being displayed on the TV screen. Such a self-formatting content receiver includes on-board image processing capability that provides continuous video analysis to detect changes in program formatting and convert each frame as it is received in real time, as opposed to processing and re-releasing an entire program or movie, or relying on the viewer to re-format programs manually. In response to detecting a change, aspect ratio adjustments are made as needed. Because the self-formatting content receiver has access to the video data before it is displayed, such automatic on-the-fly adjustments ensure that the viewer's experience during program changes is seamless and without distortion. Subscribers can influence decisions made by the content receiver by pre-setting viewer preferences for aspect ratio adjustment.

  • Patent number: 10530387
    Abstract: A system orders a set of objects to be optimally compressed using techniques such as delta encoding which compress data by saving differences between sequential objects. In one embodiment, the system determines transition costs associated with transitioning from each object in the set to each other object in the set. The system determines an ordering of the objects that minimizes a total of all the transition costs and compresses the set in the determined order. In another embodiment, the system determines an estimated optimal ordering for data compression. The system extracts feature values from the objects and applies a projection function to the feature values to generate scalar representations of the objects, for example, by projecting the feature values onto a space filling curve. An ordering of the scalar values for the objects determines an ordering for compressing the objects.

  • Patent number: 10349005
    Abstract: Various embodiments are generally directed to techniques for determining whether to use an interpolated frame or repeat a base frame in up-converting the frame rate of a base video stream to generate an up-converted video stream. A device to up-convert a frame rate includes an analysis component to analyze a pair of temporally adjacent base frames and a motion vector associated with movement of an object between the pair of base frames to determine a degree of visual artifacts involving an edge of the object in an interpolated frame, and a selection component to compare the degree of visual artifacts to a threshold and select the interpolated frame for insertion between the preceding base frame and the following base frame in up-converting a frame rate of the base video stream to generate an up-converted video stream based on the comparison. Other embodiments are described and claimed.

  • Patent number: 10290256
    Abstract: A subframe data generation unit 12 generates brightness data Ew, Er, Eg, Eb of four colors by obtaining distributed brightness with regard to each pixel based on brightness data Dr, Dg, Db of three colors, the distributed brightness being brightness of a white subframe, and obtaining brightness of red, green, and blue subframes with regard to each pixel based on the brightness data Dr, Dg, Db of three colors and the distributed brightness. The subframe data generation unit 12 obtains the distributed brightness by setting an initial value of the distributed brightness to a maximum value that the distributed brightness can take, and then performing adjustment processing for reducing a difference between the distributed brightness of adjacent pixels. With this, a flicker phenomenon occurring at an edge portion of a display image is suppressed.

  • Patent number: 10249261
    Abstract: A display controller includes a lookup table configured to store a plurality of reference data and an interpolation circuit configured to calculate a corrected datum by performing correction on an image datum based on the plurality of reference data. The interpolation circuit determines whether the image datum is less than a reference value, calculates the corrected datum using a first interpolation method when the image datum is less than the reference value, and calculates the corrected datum using a second interpolation method different from the first interpolation method when the image datum is equal to or greater than the reference value. When the corrected datum is calculated using the first interpolation method, the interpolation circuit calculates the corrected datum based on a first reference datum, which corresponds to a product of the image datum and the reference value, among the plurality of reference data.

  • Patent number: 10185888
    Abstract: An image processing system and method for determining an intrinsic color component of one or more objects present in a sequence of frames, for use in rendering the object(s), is described. At least some of the frames of the sequence are to be used as lighting keyframes. A lighting estimate for a lighting keyframe A of the sequence of frames is obtained. An initial lighting estimate for a lighting keyframe B of the sequence of frames is determined. A refined lighting estimate for the lighting keyframe B is determined based on: (i) the initial lighting estimate for the lighting keyframe B, and (ii) the lighting estimate for the lighting keyframe A. The refined lighting estimate for the lighting keyframe B is used to separate image values representing the object(s) in the lighting keyframe B into an intrinsic color component and a shading component, for use in rendering the object(s).

  • Patent number: 10178394
    Abstract: Video coding techniques are disclosed for resource-limited destination display devices. Input video data may be coded by converting a first representation of the input video to a resolution of a destination display and base layer coding the converted representation. Additionally, a region of interest may be predicted from within the input video. The predicted ROI may be converted to a resolution of the destination display, and the converted ROI may be enhancement layer coded. The base layer coded data and the enhancement layer data may be transmitted to the destination display where the coded base layer data is decoded and displayed until a zoom event occurs. When a zoom event occurs, both the coded base layer data and the coded enhancement layer data may be decoded and displayed. Thus, the switchover from a first field of view to an ROI view may be performed quickly.
