Imaging device, imaging method, and on-board imaging system

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.

Examination device and examination method

An imaging unit photographs an object, and obtains a visible light signal and an invisible light signal. A visible light luminance extraction unit extracts a visible light luminance signal. An invisible light luminance extraction unit extracts an invisible light luminance signal. A color signal extraction unit extracts color signals from the visible light signal and corrects the color signals. An image synthesis unit uses the visible light luminance signal and the invisible light luminance signal to synthesize a luminance signal and generates a color image using the synthesized luminance signal and the corrected color signals. In accordance with the value of the visible light luminance signal, the control unit controls a synthesis ratio between the visible and invisible light luminance signals, a gain for the color signals to be corrected in the color signal extraction unit, and color noise removal to be performed in the color signal extraction unit.

Imaging device

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. The data in the memory is subjected to a process of compression and encoding as moving images so that the image of position information and the user's captured image can be processed as a set of moving images. This accordingly enables to provide a system and method for recording and reproducing a set of moving images of the combination of an image of position information and a user-captured image with no need for a complicated process.

An imaging apparatus which can correct a shaking of the hand whether a moving picture is taken or a still picture is taken. Exposure is carried out within a shorter time than a predetermined exposure time to output a charge. Exposure and delivery of charge is carried out plural times to accumulate charges. An address for accumulation is changed in accordance with information of a shaking occurring within the shorter time and a signal due to the shaking and a signal before the shaking are accumulated at the address. Alternatively, a camera-shake is detected by using a sensor such as a gyroscope adapted to detect an angular velocity or an acceleration of a shaking of the imaging apparatus itself.
