    摘要: Image data is encoded for distribution in a lower bit-depth format. The image data has a range that is less than a maximum range and is mapped to the lower bit depth format using a mapping such that a ratio of a range of the lower bit depth representation to a maximum range of the lower bit depth representation is greater than a ratio of the range of the image data is associated with lower bit depth representation. The metadata may be used downstream to reverse the mapping so that tonal detail is better reproduced.

    摘要: Systems, apparatus and methods are provided for generating, delivering, processing and displaying video data to preserve the video creator's creative intent. Metadata which may be used to guide the processing and display of the video data is dynamically generated and embedded in the video data throughout a video delivery pipeline. The metadata may be written in chrominance data for black video frames, black mattes or bars framing an image, and/or in the other image areas for which luminance values are zero or below a threshold value.

    摘要: Methods for transmitting additional information together with image data involve replacing pixel values to take in-gamut points to out-of-gamut points. The additional information may constitute metadata describing the image data and/or useful for controlling display and/or processing of the image data; watermark information; or other information. In some embodiments the image data is restored to its original form after extraction of the additional information.

    摘要: Apparatus and methods are provided to map out-of-gamut points to in-gamut points. Embodiments transform image data for presentation on a display or medium having a gamut different from that of the image data. Different mapping algorithms may be applied based in part on luminance of the points being mapped. Embodiments apply a reduced dataset representing a gamut boundary. Irregular gamuts may be accommodated

    摘要: A modular board to board mezzanine ball grid array BGA connector includes a plug, a receptacle and if needed an adapter. The plug and the receptacle can be made form the same base pieces to accommodate different stack heights. If a greater stack height is needed, spacers can be used in the plug and the receptacle to accommodates a greater selected stack height. The plug and the receptacle both include a base having an interstitial diamond recesses in which the solder balls are disposed and in which one end of a contact is inserted. The plug may further include a plug cover that can be connected to the base, and the receptacle may include a receptacle cover that fits over its base. The plug can have a plug contact assembly, and the receptacle can have a receptacle contact assembly. The plug and the receptacle can be mated by mating the plug cover to the receptacle cover and the receptacle contacts to the plug contacts. If a larger stack height is desired, a spacer can be attached to the base of either or both the plug or the receptacle to achieve a larger stack height.

    摘要: Systems and methods of image processing are provided for a display having a light source modulation layer and a display modulation layer. A section of a perceptual curve, such as a DICOM curve, is extracted for each frame of image data, based on a profile of expected luminance on the display modulation layer from light emitted by the light source modulation layer. The section of the perceptual curve may be used to determine a desired-total response curve which maps display modulation layer input control values to corresponding output luminance values. The desired-total response curve and a display modulator-specific response curve may be applied to image data to generate control values for driving the display modulation layer.

    摘要: Displays such as televisions, computer monitors, and the like may boost (124) the dynamic range of input image data (121). Dithering (128) may be provided to mitigate artefacts made visible as a result of the boosting. Color correction (124) may be implemented. The color correction may compensate for differences between a color of a backlight and a desired white point.
