  • Patent number: 11074698
    Abstract: A congestion degree estimating unit (12) which estimates, for each image frame, a congestion degree of an area in which each object detected by an object detecting unit (11) is present is provided. An object selecting unit (13) refers to an estimation result of the congestion degree by the congestion degree estimating unit (12) for each image frame, and selects an object present in an area the congestion degree of which is equal to or lower than a first threshold out of one or more objects detected by the object detecting unit (11).

  • Patent number: 11075570
    Abstract: There is provided a rotary electric machine that ensures improving a maximum torque and a rated power factor while reducing an increase in a starting current. In view of this, the rotary electric machine includes a shaft, a rotor, and a stator. The rotor is fixed to an outer periphery of the shaft. The stator is located so as to surround an outer periphery of the rotor. The rotor includes a rotor iron core including a plurality of rotor slots located at predetermined intervals in a circumferential direction and rotor bars inserted into the rotor slots. Rotor slits communicate with outer peripheral sides of the rotor slots. The rotor slits have a width ws in a circumferential direction. The width ws is smaller than a height hs in a radial direction of the rotor slit, and when a rated current is denoted as I1, a turn ratio (primary/secondary) is denoted as Tr, and a magnetic permeability in a vacuum is denoted as ?0, a relationship of ws>?0×I1×Tr/0.6 is met.

  • Patent number: 10931946
    Abstract: When carrying out an average prediction, an intra predictor carries out a filtering process on target pixels of the intra prediction located at an upper end and a left end of the block, the filtering process using an intermediate prediction value, which is an average value of adjacent pixels of the block, and at least one adjacent pixel of the target pixel. The intra predictor also sets a filter coefficient to ¾, associated with the intermediate prediction value for a target pixel at the left end of the block other than the target pixel at an upper left corner of the block, and sets a filter coefficient to ¼, associated with the adjacent pixel adjacent to the left side of the target pixel at the left end of the block. As a result, prediction errors locally occurring can be reduced, and the image quality can be improved.
