  • Publication number: 20170309257
    Abstract: A display control device includes a determination unit and a controller. The determination unit determines whether or not a subject viewed from a passenger falls within a display range of a virtual image based on the position information of the subject acquired from a recognition unit that recognizes the subject in the foreground of a moving object and the estimated value of a depression angle acquired from an estimation unit that estimates the depression angle when the virtual image is viewed from the passenger. In a case where the subject is determined to fall within the display range, the controller controls a display unit to generate an image that represents a first display image showing the information corresponding to the subject.

  • Publication number: 20150201150
    Abstract: A video output device according to the present disclosure synthesizes a plurality of videos into a video to be displayed. The video output device includes image processing unit and output unit. The image processing unit extracts a plurality of reference frames from any one reference video selected from the plurality of the videos captured by an imaging unit, and extracts a corresponding frame, most similar to a respective one of the reference frames, from each of the videos excluding the reference video. The output unit outputs a synthesized frame which image processing unit synthesizes from the each of the reference frame and the corresponding frame.

  • Publication number: 20110058594
    Abstract: In power line communication using a power line as a transmission path, a transmitter terminal transmits a communication signal while changing a phase parameter of the communication signal transmitted, in the continuous communication signal, according to an impedance variation amount on the transmission path. In this communication method, the communication signal is received stably with no variation in the phase parameter of the communication signal in response to the impedance variation amount on the transmission path, permitting high-speed data communication with reduced communication error.

  • Publication number: 20080320170
    Abstract: The present invention provides a data communication apparatus for solving the following problem. When generating coded frames of multiple data streams, in the case where there is a bias in code amount of the generated coded frame, the communication apparatus is instantaneously overloaded, causing packet losses. The network cameral terminal which is the data communication apparatus includes a sensor unit that takes images or audio information, a compression unit that compression-codes the image or the audio signal and generates coded frames (I-frame, P-frame, B-frame and others), a frame control unit that controls types of the coded frame generated by the compression unit using a generation table held in a generation table holding unit, and a communication unit that transmits the coded frames to multiple communication terminals on the network in parallel.
