    摘要: Methods and apparatus are provided for encoding and decoding image data using localized gamut definitions. The localized gamut definitions may be defined based on gamut characteristics of the image data. A gamut transform is applied to the image data wherein color coordinates specified by the image data are mapped to corresponding color coordinates in the localized gamut definition. Use of localized gamut definitions may facilitate image data compression of increased color depth specification of image data.

    摘要: Tone and/or gamut mapping apparatus and methods may be applied to map color values in image data for display on a particular display or other downstream device. A mapping algorithm may be selected based on location and/or color coordinates for pixel data being mapped. The apparatus and methods may be configured to map color coordinates differently depending on whether or not a pixel corresponds to a light source in an image and/or has special or reserved color values.

    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: 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: Light emitting elements in an illumination unit of a display may be blanked during updates of pixels of a spatial light modulator (SLM). Updates of pixels in different segments of the SLM may be coordinated with blanking of corresponding segments of the illumination unit. Updating of segments of a light source (30A-30D) may be coordinated so that not all segments are updated in each frame (34A-37D) of a video.

    摘要: A backlight for a display comprises a plurality of independently controllable groups of light emitters. The brightness levels of the groups of light emitters are controllable by pulse width modulation (PWM) signals generated by PWM driving circuits. The phases of PWM signals to different groups of light emitters are configured to be offset by different amounts, so as to stagger the start times of light emitters of different groups. Such phase-shifting of PWM signals may result in total power consumption that ramps up more gradually, is distributed more evenly over time, and is held to a lower maximum value than if the same PWM signals were not phase-shifted. The duration of a first PWM cycle of PWM signals for an image may also be made longer than subsequent PWM cycles for the image so as to extend the initial power ramp-up time.
