Techniques are provided herein for secure display device communications. In one example, a video communications device provides, to a display device over a first connection, communication information that enables the display device to contact a server over a second connection. The video communications device further provides, to the display device over the first connection, a command configured to initiate an interaction with the server. The server obtains, from the display device over the second connection, a message initiating the interaction in response to the command based on the communication information.

An image processing method includes an electronic device that outputs a first frame rate when the electronic device detects that ambient light brightness in a current environment is less than or equal to a first preset light brightness threshold; collects first video data based on the first frame rate, where the first video data includes a plurality of frames of images; and performs frame interpolation on the frames of images to obtain and store second video data, where a frame rate of the second video data is greater than the first frame rate.

An electronic device may include an interface unit, and a processor for storing information related to a plurality of broadcast channels that can be received through the interface unit, receiving a user input for selecting a channel number, identifying, on the basis of the stored information related to the plurality of broadcast channels, a broadcast standard corresponding to the selected channel number if a broadcast signal of a channel corresponding to the channel number selected according to the user input is not received, processing the frequency band of the broadcast signal corresponding to the selected channel number according to the identified broadcast standard, and controlling so that the stored information related to the plurality of broadcast channels is updated according to a processing result.

A super-resolution coding mode is described. Encoded image can be decoded by decoding, from an encoded bitstream, a flag indicating whether an image was encoded using the super-resolution mode. The image is encoded at a first resolution. Responsive to the flag indicating that the image was encoded using the super-resolution mode, bits indicating an amount of scaling of the image are decoded. The image is decoded from the encoded bitstream to obtain a reconstructed image at the first resolution, and the reconstructed image is upscaled to a second resolution using the amount of scaling to obtain an upscaled reconstructed image. The second resolution is higher than the first resolution. Loop restoration filtering is applied to the upscaled reconstructed image using loop restoration parameters to obtain a loop restored image at the second resolution.

Normalized resolutions are determined for first and second regions of interest of an initial video stream captured by a video capture device located within a physical space. The first region of interest is associated with a first conference participant within the physical space and the second region of interest is associated with a second conference participant within the physical space. Instructions are transmitted to the video capture device to cause the video capture device to capture, at the normalized resolutions, a first video stream associated with the first region of interest and a second video stream associated with the second region of interest. The first and second video streams conform sizes and quality levels of the first and second conference participants within separate user interface tiles of a conferencing software user interface to which the first and second video streams are output.

Intelligent reframing techniques are described in which content (e.g., a movie) can be generated in a different aspect ratio than previously provided. These techniques include obtaining various video frames having a first aspect ratio. Various objects can be identified within the frames. An object having the highest degree of importance in a frame can be selected and a focal point can be calculated based at least in part on that object. A modified version of the content can be generated in a second aspect ratio that is different from the first aspect ratio. The modified version can be generated using the focal point calculated based on the object having the greatest degree of importance. Using these techniques, the content can be provided in a different aspect ratio while ensuring that the most important features of the frame still appear in the new version of the content.

The present disclosure provides a conference device, a method of controlling the conference device, and a computer storage medium. The conference device includes a display, an image sensor, a holographic projector, and a controller configured to identify, by using an image data from the image sensor, a modification action performed at a target location for a holographic image projected by the holographic projector, modify holographic projection data based on the modification action, and convert modified holographic projection data into modified two-dimensional imaging data.

A de-interlacing processing method, a de-interlacing processing device and a computer-readable storage medium are provided. The method includes acquiring image content characteristic information of a pixel point to be interpolated; and determining according to the image content characteristic information whether a de-interlacing algorithm based on motion adaptive or a de-interlacing algorithm based on motion compensation is adopted to perform de-interlacing processing.

In various implementations, a method of presenting video streams at a head-mountable device (HMD) includes generating a first video stream at a first frame rate for a first display portion. In some implementations, the first frame rate indicates a rate at which frames are presented by the first display portion. In various implementations, the method includes generating a second video stream at a second frame rate for a second display portion. In some implementations, the second frame rate indicates a rate at which frames are presented by the second display portion. In some implementations, the second frame rate is within a threshold relative to the first frame rate. In various implementations, the method includes temporally shifting the second video stream relative to the first video stream so that a majority of refresh times of the first display portion are different from refresh times of the second display portion.

The present invention provides to a recording apparatus and method for recording data, in particular video data associated with a vehicle. Video data are only recorded, as long as a predefined trigger event is true. Upon detecting such a trigger event, the trigger event is further analyzed and the recording of the video data is immediately stopped when it is detected that the trigger event is no longer valid. In this way, the recording of the video data can be limited for reducing the amount of video data to be stored. According to further embodiments, the amount of video data to be recorded can be further minimized by adapting the video frame rate, the resolution, and compression rate or color format of the video data.
