Abstract: 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.

Abstract: In some embodiments, a display device is disclosed to optically communicating display parameters. The device receives input image data. Embedded in the input image data is a code value identifying a request for a portion of a display parameter of the display device. The device decodes the embedded code value. The device generates an optical image based on the request and transmits the generated optical image to an output of the display device to communicate the requested portion of the requested display parameter.

Abstract: A video content controller includes a memory and a microprocessor. The memory is configured to store non-transitory computer-readable instructions and video data representing a temporally-varying scene having a plurality of scene-regions. The microprocessor adapted to execute the instructions to (i) receive a current stream-segment of a video stream corresponding to a first scene-region of the plurality of scene-regions during a current playback-time interval, (ii) download, to a memory, a first video segment of a tagged scene-region within the first scene-region, (iii) receive a first display-region signal indicating at least one of a selection and a feature of the first scene-region, (iv) combine the current stream-segment and the first video segment as a video signal, and (vi) transmit, in response to the first display-region signal, the video signal to a display device.

Abstract: A spherical image of a spatial environment is received and contains spherically arranged pixel values indexed by a time value. The spherical image is represented in a content creation coordinate system in reference to a spatial position in the spatial environment. The spatial position is indexed by the time value. A spatial relationship is determined between the content creation coordinate system and a spherical image reference coordinate system. Based at least in part on the spatial relationship and the spherically arranged pixel values, spherical distributions of image metadata are determined for the spherical image.

Abstract: Image data relating to real-world objects or persons is collected from a scene while collecting audio data relating to the real-world objects or persons from the same scene. The audio data is used to derive sound objects corresponding to the real-world objects or persons. The image data is used to derive video objects corresponding to the real-world objects or persons. Based on the sound objects and the video objects, candidate salient objects are generated. A salient object is selected from among the candidate salient objects. Perceptual enhancement operations are performed on the selected salient object.

Abstract: Systems and methods are disclosed for dynamically adjusting the backlight of a display during video playback or for generating filtered video metadata. Given an input video stream and associated metadata values of 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. At least one filtering coefficient of the temporal filter is adapted based on a logistic function controlled by slope and sensitivity values. The instantaneous dynamic range of a target display is determined based on the filtered metadata values and the minimum and maximum brightness values of the display.

Abstract: 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.

Abstract: 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.
