The head-up display includes an imaging position changer configured to change a position of a virtual image between a far visual position far from an observer and a near visual position close to the observer. The imaging position changer inclines the virtual image at the far visual position by a second inclination angle with respect to a perpendicular plane to a reference light beam reaching a center of a viewpoint region in which a viewpoint of the observer is located, to move an upper end thereof in a forward direction of the moving object, and inclines the virtual image at the near visual position by a first inclination angle smaller than the second inclination angle with respect to the perpendicular plane to the reference light beam, to move the upper end in the forward direction of the moving object.

A video display system includes a display unit, a projection unit, and a display control unit. The display unit displays an image. The projection unit projects a virtual image onto a target space with outgoing light of the display unit. The display control unit shifts a projection position of the virtual image by changing at least one of a projection distance or an angle of depression. The projection distance is a distance from a viewpoint to the virtual image. The angle of depression is an angle from which the virtual image is viewed from the user's viewpoint. The display control unit changes the projection distance of the virtual image in accordance with a distance instruction and changes at least one of the projection distance or the angle of depression such that the virtual image is projected onto a displayable region of the target space.

An image processing device includes: a first obtainer that obtains a captured image from an imaging device that captures a view in front of a vehicle; a second obtainer that obtains a remaining distance to a next guide point; an image processor that performs image processing on a specified region, in the captured image, corresponding to a position distanced by the remaining distance; and an output unit that outputs the captured image processed by the image processor, wherein the image processor controls an edge strength of a subject in the specified region, in accordance with the remaining distance.

An object of the present invention is to provide an adaptor device for a source device that can reduce a connection time to a switching destination in the case where a connection destination is switched. For this, an adaptor device for a source device () includes a storage unit () that stores format information that is information indicating the format of the video signal; a dummy signal generating unit () that generates a dummy signal that is a dummy video signal having the same format as that specified by the format information obtained from the storage unit (); a control unit () that causes the dummy signal generating unit () to generate the dummy signal when the video signal is not obtained from the source device; and a wireless transmitting and receiving unit () that selectively wirelessly transmits the video signal and the generated dummy signal.

Adaptor device for source device and control method of adaptor device for source device

In response to a video and audio bandwidth allocation request command signal and an audio bandwidth allocation request command signal from a source device, a coordinator device allocates a first reservation period for transmitting AV stream data from the source device to a sink device and a second reservation period for transmitting audio stream data from the source device to a sink device within a predetermined frame period, and transmits a beacon signal including information on allocation of the first reservation period and the second reservation period.

A source device combines right-eye video frame data with left-eye video frame data into combined video frame data every video frame. Then, the source device generates a plurality of packets by dividing the combined video frame data into packets so as to insert information on a horizontal position for a horizontal display time interval and information on a vertical position for a vertical display time interval of a first pixel of the combined video frame data stored in the packets, into a header of each packet for transmitting the combined video frame data, as information for identifying right-eye video frame data and left-eye video frame data.

In the wireless HDMI converter, appropriate audio data input switching is performed, and, when an instruction is received, an audio data extraction unit extracts audio data from video and audio data received by an HDMI input interface from an STB, and an optical audio output interface outputs the extracted audio data to a home theater, thereby avoiding failure of wireless communication by a wireless interface or deterioration of the quality of such wireless communication.

Input and output switching device and input and output switching method

A router, if judging that a routing function is impossible to execute, sends out a connection instruction message including the address of a terminal on a local network terminating the relaying flow, to another router to solicit switching. The router having received the connection instruction message starts a process for connecting with an external network while executing a process for link connection with a terminal, and then sends out a connection completion notice message when the connection with both the external network and the terminal is established. This process enables the router to switch a path rapidly.

Multi-interface communication device, terminal, and path switching method

A source device transmits an output format notify message for video data to a sink device before transmitting the video data to the sink device, the output format notify message including a 3D field storing data for identifying whether the video data to be transmitted is two-dimensional video data or three-dimensional video data transmitted using frame packing. In response to this, the sink device identifies a type and a format structure of the video data, and decodes the received video data based on the identified type and format structure of the video data.

Method of transmitting video data for wirelessly transmitting three-dimensional video data

A source device counts a clock CLKpixel for pixel data using a transmitting counter, adds a counted value Csource(t) of the transmitting counter at a timing of transmitting a video packet Pvideo to the sink device to a header part of the video packet Pvideo as a time stamp value Csource(t), and transmits the video packet Pvideo to the sink device. The sink device receives the video packet Pvideo, extracts the time stamp value Csource(t) from the header part of the video packet Pvideo, generates a fixed reference clock CLKref based on the counted value Csource(t) of the transmitting counter using a first PLL, circuit, and generates the clock CLKpixel for the pixel data of the source device based on the reference clock CLKref using a second PLL circuit.
