  • Patent number: 11908199
    Abstract: Image data captured from a traveling vehicle is considered, and it is not possible to reduce the transmission band of the image data. It is assumed that a radar 4 mounted in a traveling vehicle 10 detects a certain distant three-dimensional object at a time T in a direction of a distance d1 [m] and an angle ?1. Since the vehicle 10 travels at a vehicle speed Y [km/h], it is predicted that a camera 3 is capable of capturing the distant three-dimensional object at a time (T+?T) and an angle ?1 or at a distance d2 [m]. Therefore, if a control unit 2 outputs a request to the camera 3 in advance, so as to cut out an image of the angle ?1 or the distance d2 [m] at the time (T+?T), when the time (T+?T) comes, the camera 3 transfers a whole image and a high-resolution image being a cutout image of only a partial image, to the control unit 2.

  • Publication number: 20240032888
    Abstract: The array of reception beam data sets obtained by transmitting and receiving ultrasonic waves to and from a subject constitutes a two-dimensional data space. Based on the Doppler signals, a distribution data calculation unit calculates, for each of data elements in the two-dimensional data space, at least one of power of the Doppler signal, the velocity of tissue in the subject, and the velocity dispersion of tissue in the subject. A discrimination index map generation unit generates a discrimination index map indicating the likelihood of being a blood flow region A in the two-dimensional data space composed of the array of reception beam data sets, based on distribution data that are set for each of regions of interest in the two-dimensional data space. Based on the Doppler signal and the discrimination index map, a blood flow image forming unit forms a blood flow image with reduced blooming artifacts.

  • Publication number: 20220413136
    Abstract: A clutter signal mixed in a blood flow signal is reduced in a color Doppler, and blood flow visibility is improved. A combination of parameters that maximize a difference between a blood flow and a clutter (a signal other than the blood flow) is determined by analyzing a reception signal, a clutter estimated value (a value indicating a degree of being estimated as a clutter) is set based on the combination, and a reduction coefficient map (hereinafter, simply referred to as a reduction map) that reduces a clutter signal is generated based on the estimated value. The clutter signal is reduced by multiplying the reception signal (an IQ signal after quadrature detection) by the reduction map.
