  • Publication number: 20120069187
    Abstract: A technology for intuitively recognizing a positional relation between a vehicle and an object is provided. In an image display system, in a display image provided to a driver, the side region of the vehicle in a direction indicated by a direction instructing device is displayed in large size. Accordingly, the object that may contact with the vehicle is easily found out, so that a minor crash accident can be effectively prevented. Since a synthetic image viewed from a virtual viewpoint directed from a rear position of the vehicle toward the front side of the vehicle is displayed, the side area of the vehicle is displayed in the same visual field direction as the direction of the visual field of the driver. Accordingly, the driver can intuitively recognize the positional relation between the vehicle and the object, without undertaking complicated determination such as conducting coordinate transformation in his/her mind.

  • Publication number: 20120068840
    Abstract: A technology that does not require complicated operation to select a display mode is provided. In an image display system, a back mode stores a display mode that has been recently set as a current mode. When the display mode becomes the back mode next time, the display mode that has been recently set as a current mode is set as a current mode immediately after the display mode becomes the back mode. Accordingly, the driver does not need to perform the complicated operation to select a desired display mode each time the vehicle is reversed.

  • Publication number: 20120069188
    Abstract: A technology for displaying images on a displaying apparatus mounted on a vehicle is provided. In response to a predetermined instruction signal, synthetic images viewed from a virtual viewpoint around and above the periphery of the vehicle are generated based on a plurality of images acquired from a plurality of cameras for capturing the periphery of the vehicle. The plurality of synthetic images, in which a position of a viewpoint moves sequentially varies such that the synthetic images move in a circle around the vehicle, are sequentially output to the displaying apparatus. Accordingly, the user monitors the entire circumference of the vehicle from the viewpoint where the user sees the vehicle in front of user's eyes, so that the user can intuitively recognize the positional relation between the vehicle and an obstacle from one screen.

  • Publication number: 20110291863
    Abstract: An in-vehicle display apparatus includes a communication device and an in-vehicle device. The communication device acquires information posted by the user and geographical location data indicating the destination of the posted information and classifies the acquired posted information into categories. The communication device generates map data in which the posted information is displayed in a display format corresponding to the classified category at a position on the map specified by the geographical location data that is acquired together with the posted information and transmits the map data to the in-vehicle device. The in-vehicle device displays the received map data on, for example, a liquid crystal monitor.

  • Publication number: 20110291860
    Abstract: An in-vehicle display apparatus includes a communication device and an in-vehicle device. The communication device acquires posted information and geographical location data indicating the destination of the posted information. Then, the communication device generates map data in which the posted information is displayed at a position specified by the geographical location data which is acquired together with the posted information. In addition, the communication device changes a method of displaying the posted information on the generated map data on the basis of the time elapsed from the posting of the information to the acquisition of the posted information and the category of the posted information. Then, the communication device transmits the map data in which the display method of the posted information is changed to the in-vehicle device. The in-vehicle device displays the received map data on, for example, a liquid crystal monitor.

  • Publication number: 20110221890
    Abstract: An object tracking apparatus that tracks an object in a time-series image including a plurality of frames has a positional relationship determining unit that determines a positional relationship between the object and an analog having a feature similar to that of the object in an earlier frame of a current frame, an object position specifying unit that specifies a position of the object in the current frame, and an analog position specifying unit that specifies a position of the analog in the current frame when the analog exists in a surrounding region that is of a predetermined region around the object. The object position specifying unit predicts the position of the object in the current frame to specify the position of the object based on the position of the object and a motional state of the object in an earlier frame when the positional relationship is in a first state.

  • Publication number: 20100195870
    Abstract: The present invention relates to a tracking method and a tracking device adopting multiple observation models with different life spans. The tracking method is suitable for tracking an object in a low frame rate video or with abrupt motion, and uses three observation models with different life spans to track and detect a specific subject in frame images of a video sequence. An observation model I performs online learning with one frame image prior to the current image, an observation model II performs online learning with five frames prior to the current image, and an observation model III is offline trained. The three observation models are combined by a cascade particle filter so that the specific subject in the low frame rate video or the object with abrupt motion can be tracked quickly and accurately.
