Disclosed are an image processing method and an apparatus for a virtual reality device, and a virtual reality device. The image processing method for a virtual reality device includes: receiving, by a HDMI, a video signal in a HDMI format; converting the video signal in the HDMI format into a video signal in a CSI format; and performing at least one of asynchronous timewarp processing and asynchronous spacewarp processing on the video signal in the CSI format, to generate a video signal in a DSI format. Based on the image processing method, a displayed image of the virtual reality device has a high display frame rate. In addition, the virtual reality device may also receive and process a video signal without using the HDMI, and store video and audio data of the video signal to a greatest extent.

A system and method for controlling and selecting sources in a room on a network. The system allows a remote viewer to create a virtual presence within the room by providing the available displays, corresponding to the sources, to the remote viewer. The system includes a standardizing technique for improving the communication and overall switching of data for streaming on a network. The system can include a recording server for performing dual recording of the video files in each of a local database and a remote database. A graphical user interface (GUI) display is provided to guide a local user through a medical procedure in the standardized system.

Systems and methods for signal communication over an optical link are described. One aspect includes receiving a source CONFIG1 signal from a DP master device and a sink CONFIG1 signal from a sink terminal. The source and sink CONFIG1 signals are analyzed. It is determined whether a signal transmission mode is a DP protocol. For a DP protocol, a pair of source AUX signals is received from the DP master device. A pair of sink AUX signals is received from the sink terminal. Communication resource contention between the source and sink AUX signals is identified. A communication direction of the communication resources is transitioned to give the source AUX signals precedence over the sink AUX signals. The source AUX signals are transferred to the sink terminal via the communication resources. The direction of the communication resources is again transitioned. The sink AUX signals are transferred to the DP master device.

The resolution of a low-resolution image is made high and a stereoscopic image is displayed. Resolution is made high by super-resolution processing. In this case, the super-resolution processing is performed after edge enhancement processing is performed. Accordingly, a stereoscopic image with high resolution and high quality can be displayed. Alternatively, after image analysis processing is performed, edge enhancement processing and super-resolution processing are concurrently performed. Accordingly, processing time can be shortened.

A transmission method in the present disclosure includes; obtaining an image and image signal characteristics information indicating one of an opto-electrical transfer function (OETF) or an electro-optical transfer function (EOTF) as image signal characteristics of the image; and transmitting a signal including the image and the image signal characteristics information. According to the transmission method in the present disclosure, a receiving device that received a high dynamic range (HDR) image and a standard dynamic range (SDR) image transmitted through broadcasting or the like can display these images appropriately.

A method and an apparatus for determining a small-object region in a video frame. The method includes dividing a current video frame into at least two regions, and determining a global motion vector corresponding to each region; determining an interframe motion vector of each group of adjacent frames in multiple video frames that include the current video frame and a reference frame of the current video frame; determining a candidate small-object region in the current video frame according to the interframe motion vector of the each group of adjacent frames and the determined global motion vector corresponding to each region; and performing filtering on the candidate small-object region in the current video frame, and determining a region obtained after the filtering as a small-object region in the current video frame.

The present invention aims to provide an image processing device which enables reconstruction of a sharp high resolution image similar to the original of the unknown input image.

An image processing device according to one of the exemplary aspects of the present invention includes: inferring means for selecting, for each of local unknown patches including a target unknown patch, candidate patches from a plurality of input patches based on similarity to the local unknown patch, the local unknown patches being images generated from a part of an unknown image, the plurality of input patches being images generated from a plurality of input images, a subject ID (Identifier) being correlated with the input patches that are generated from a input image to which the subject ID is assigned in the plurality of input image; first score calculation means for calculating a score representing nearness of a candidate patch in the candidate patches to a local unknown patch in the local unknown patches; and patch replacement means for calculating a score summation for the subject ID by summing up scores of the candidate patches being correlated with a same subject ID in the candidate patches of the local unknown patches, and selecting, as a selected patch being used for reconstruction of a reconstruction image, a candidate patch that is correlated with the subject ID for which the score summation is highest from the candidate patches selected for the target unknown patch.

An driving method for a display panel, the display panel having a first resolution. The driving method comprises: converting RGB signals of an input image having a second resolution into YUV signals corresponding to an output image, a resolution of the output image being not smaller than the second resolution; converting the YUV signals into RGB signals corresponding to the output image; converting the RGB signals corresponding to the output image into driving signals for driving the display panel; and outputting the driving signals to the display panel. Display panels having the resolution of 10240×4320 can be driven by using the driving method.

Systems and methods for low-delay video streaming featuring multiple video compression ratios. One embodiment of the system includes: a real-time video encoder (RT-VE) that receives an incoming high-definition uncompressed video (HD-UV), processes the incoming HD-UV according to first and second compression ratios, and sends the processed video over a resource reservation communication link to a real-time video decoder (RT-VD). The compression delay added by the RT-VE is below the duration of a single video frame, and the RT-VD converts the processed video into an outgoing HD-UV. Wherein on-the-fly switches between the first and second compression ratios, while continuing to receive the incoming HD-UV uninterruptedly, are both visually lossless switches and maintain a total delay between corresponding frames of the incoming HD-UV and the outgoing HD-UV that is below duration of two video frames.
