  • Publication number: 20170000463
    Abstract: A plurality of frames are generated by performing a pre-scan while sequentially setting a plurality of receive delay data based on a plurality of in vivo sound velocities. An optimum sound velocity calculation unit performs waveform analysis for each luminance waveform along a beam scanning direction on each of the frames. An optimum sound velocity map is obtained by mutually comparing a plurality of results of the waveform analysis of the plurality of frames. A control unit calculates the receive delay data for the main scan on the basis of the optimum sound velocity map. Specifically, waveform analysis for a high luminance portion (peak portion) and waveform analysis for a low luminance portion (recess portion) are performed in the waveform analysis. Thus, an optimum sound velocity map for the high luminance portion and an optimum sound velocity map for the low luminance portion are obtained.

  • Patent number: 9123247
    Abstract: A surrounding area monitoring apparatus for vehicle includes an infrared camera mounted on a vehicle for capturing images of surrounding area around the vehicle, a unit for generating and displaying images based on image data captured by the camera, and a controller for calibrating output of the camera with respect to a relation between pixels, based on image data produced by imaging a surface of a shutter that opens and closes an aperture introducing a light to the camera, The controller estimates whether a temperature of the camera is stable, based on an operation state of the vehicle, and determines a possibility that a driver is looking at the unit, based on a behavior of the vehicle. When the temperature of the camera is estimated stable and the possibility that the driver is looking at the unit is determined to be low, the means for calibrating executes the calibration.
