  • Patent number: 9759662
    Abstract: An examination device implements examination of matter to a large object without moving the device as a whole. The intensity of Raman scattering light obtained by laser irradiation of the object to be examined is detected to detect an attached state of an attached matter on the object to be examined. Based on a laser light irradiation position imaged and a visible image captured by a camera, the laser light irradiation position and a pixel of the camera are associated with each other, whereby irradiation area information is generated. Based on the attached state of the attached matter and the irradiation area information, an image of the attached matter present in an area imaged by the pixel of the camera is generated, and the visible image captured by the camera and the image of the attached matter are synthesized to generate a synthesized image.

  • Patent number: 8477850
    Abstract: 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.
