  • Patent number: 11936896
    Abstract: Motion vectors of a first reference frame are permitted to point to a plurality of further reference frames. A method of storing the motion vectors comprises, when a block of the first reference frame has two motion vectors (V2A, V2B) initially, selecting one of the two motion vectors, the non-selected motion vector not being stored. The selected motion vector may be scaled. This can reduce the motion vector memory size.

  • Patent number: 11931202
    Abstract: An ultrasound automatic scanning system according to an embodiment includes an ultrasound probe, a mechanical mechanism, and processing circuitry. The ultrasound probe transmits and receives ultrasonic wave. The mechanical mechanism holds and moves the ultrasound probe while an ultrasonic-wave transmission-reception surface of the ultrasound probe is pointed to a subject. The processing circuitry acquires a distance between a body surface of the subject and the ultrasonic-wave transmission-reception surface of the ultrasound probe based on reflected wave data collected while the ultrasound probe is moved by the mechanical mechanism. The processing circuitry generates, based on information of the distance, locus information of movement of the ultrasound probe when ultrasound scanning is executed on the subject. The mechanical mechanism executes ultrasound scanning on the subject by moving the ultrasound probe based on the locus information generated by the processing circuitry.
