Abstract: Power levels of a backlight are adjusted in a number of ways and based on a number of criteria. The adjustments result in a lower power consumption and, in some cases, may enhance audience attention to important objects in a scene. The adjustments comprise, for example, a combination of ramping down power (lowering final display brightness) in concert with corresponding compensatory LCD adjustments (increasing final display brightness). The adjustments may also include, for example, system dimming after ramp down/LCD adjustments are exhausted, or the shifting of an LDR2HDR curve.

Abstract: 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.

Abstract: MEMS shutters are applied in displays and imaging devices. In a display, sensors may detect light from a light source that is back-reflected by a MEMS shutter and/or ambient light that enters through the MEMS shutter. The sensors may be used to monitor performance of the light source and/or ambient lighting conditions. In an imaging device, MEMS shutters may be applied to selectively block light to prevent overexposed areas within an image.

Abstract: Method and apparatus are provided for determining and adjusting drive values for a display comprising light source modulation layer such as a backlight array of LED and a display modulation layer such as an LCD panel. Image regions for which any of the display modulation layer drive values are above a predetermined threshold maximum value or below a predetermined threshold minimum value are flagged. The light source modulation layer control values determined for a subsequent frame of image data may be adjusted based on the flagged image regions. The adjustments to the light source modulation layer control values may reduce artifacts in the displayed image and increase the efficiency of the display.

Abstract: A system and method for enhancing data coherency and potential of at least one metadata associated with a video data configured to operate in a visual dynamic range (VDR) format are detailed. One system embodiment employs a metadata framing structure which includes a header start of frame bit set, a packet type bit set, a configuration bit set, a variable depth configuration/metadata bit set, a header end of frame bit set, a timestamp bit set for specifying a frame delay count to apply the at least one metadata to the video data and a checksum check bit set. The at least one metadata is designed to embed within a code word guard bit position of at least one color channel of the video data and adaptable to embed within the VDR pipeline to enhance the quality of the video data.

Abstract: A method for color grading input video data for display on a target display comprises obtaining target display metadata indicative of a capability of the target display, obtaining input video data metadata indicative of image characteristics of the input video data, automatically determining initial values for parameters of a parameterized sigmoidal transfer function, at least one of the initial values based at least in part on at least one of the target display metadata and the input video data metadata and mapping the input video data to color-graded video data according to the parameterized transfer function specified using the initial values.

Abstract: Several embodiments of image processing systems and methods are disclosed herein whereby at least one characteristic of an image displayed on a target display is changed according to information regarding the viewer's position—e.g. distance to the target display, the visual angle the target display's subtends of the viewer's field of view. In one embodiment, luminance and/or contrast may be changed depending on the information regarding viewer's position relative to the target display.

Abstract: Methods and apparatus for signaling timing of refreshes of stereographic displays are provided. In some embodiments, light emitting elements are used to signal the start of a display refresh and to signal when the light emitting elements of the display have attained a stable optical state following the display refresh. In some embodiments, light emitting elements used to signal timing of display refreshes include light emitting elements defining a display area of the display.

Abstract: 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.
