Patent number: 8477850Abstract: A video camera is provided not only with means for receiving any general captured images but also with means for receiving images from any other video input source. The video camera is also provided with an image input arbitration section that captures, after arbitration, video data coming from these two input means, and stores the resulting data into a memory. As such, when the video input source is a video output terminal of a car navigation system, the screen of the car navigation system, i.e., map information, can be stored in a memory together with a user's captured image. When the video camera is used for monitoring, data capturing into a memory is also enabled when the video input source is a medium already carrying therein map image data, e.g., USB flash memory and SD card, and means for reading the map image data from the medium.Type: GrantFiled: April 16, 2008Date of Patent: July 2, 2013Assignee: Hitachi, Ltd.Inventors: Yasuo Mutsuro, Keisuke Inata, Hiroki Mizosoe, Akihito Nishizawa
