摘要： An embodiment of the disclosure provides a method and a system to sense a light source based on a viewer position in relation to display device. The system receives sensor data from one or more light sensors mounted on a wearable device worn by a viewer of a display device in a room, where a field of view for the light sensors covers at least a field of view of the viewer. The system identifies a light source perceived in a field of view of the viewer based on the sensor data. The system transmits data for one or more operations to be performed by the display device displaying content to the viewer to compensate for a change in brightness or color of the content caused by the light source based at least in part on light source information of the light source.

摘要： Methods, systems, and computer program products for automatically positioning a content capturing device are disclosed. A vehicle, e.g., an UAV, carries the content capturing device, e.g., a camcorder. The UAV can position the content capturing device at a best location for viewing a subject based on one or more audio or visual cues. The UAV can follow movement of the subject to achieve best audio or visual effect. In some implementations, a controller device carried by the subject can generate one or more signals for the UAV to follow. The controller device may be coupled to a microphone that records audio. The signals can be used to temporally synchronize video captured at the UAV and audio captured by the microphone.

摘要： A display system comprises light sources configured to emit first light with a first spectral power distribution; light regeneration layers configured to be stimulated by the first light and to convert at least a portion of the first light and recycled light into second light, the second light comprising (a) primary spectral components that correspond to primary colors and (b) secondary spectral components that do not correspond to the primary colors; and notch filter layers configured to receive a portion of the second light and to filter out the secondary spectral components from the portion of the second light. The portion of the second light can be directed to a viewer of the display system and configured to render images viewable to the viewer.

摘要： Systems and methods are disclosed for dynamically adjusting the backlight of a display during video playback. Given an input video stream and associated minimum, average, or maximum luminance values of the video frames in the video stream, values of a function of the frame min, mid, or max luminance values are filtered using a temporal filter to generate a filtered output value for each frame. The instantaneous dynamic range of a target display is determined based on the filtered output value and the minimum and maximum brightness values of the display. A backlight control level is computed based on the instantaneous dynamic range, and the input signal is tone mapped by a display management process to be displayed on the target display at the selected backlight level. The design of a temporal filter based on an exponential moving average filter and scene-change detection is presented.

摘要： Systems and methods for perceptually synchronizing at least one secondary display that is in a same visual environment as a primary display. The image appearance parameters may be derived from the image/video shown on the primary display can be used to map the appearance of any arbitrary content on a secondary device. To produce a visually pleasing environment for a viewer in the visual environment, systems and methods are herein disclosed for synchronizing the display settings or parameters. The synchronization may be affected by dynamically adjusting the image data rendered upon one of the primary and/or secondary displays. Such dynamic adjustments may be made in accordance with the characteristics of the primary display and/or secondary display. Such adjustments may be made to the dynamic range, color mapping, etc. of the rendering on either display.

摘要： Video data with enhanced dynamic range (EDR) are color graded for a first and a second reference display with different dynamic range characteristics to generate a first color-graded output, a second color graded output, and associated first and second sets of metadata. The first color-graded output and the two sets of metadata are transmitted from an encoder to a decoder to be displayed on a target display which may be different than the second reference display. At the receiver, a decoder interpolates between the first and second set of metadata to generate a third set of metadata which drives the display management process for displaying the received video data onto the target display. The second set of metadata of metadata may be represented as delta metadata values from the first set of metadata values.

摘要： A highlight mask is generated for an image to identify one or more highlights in the image. One or more highlight classifiers are determined for the one or more highlights in the image. One or more highlight gains are applied with the highlight mask to luminance amplitudes of pixels in the one or more highlights in the image to generate a scaled image. The one or more high-light gains for the one or more highlights are determined based at least in part on the one or more highlight classifiers determined for the one or more highlights.

摘要： An image sensor of a camera configured with a diffraction grating is used to capture a diffraction image of an image rendering surface of a display device, for example, while a target image is being rendered on the image rendering surface of the display device. The diffraction image of the image rendering surface of the display device is analyzed to obtain measurements of native display capabilities of the display device. Display capability data is transmitted to a display management module for the display device. At least a portion of the display capability data is generated from the measurements of native display capabilities of the display device that are obtained from analyzing the diffraction image of the image rendering surface of the display device.
