  • Patent number: 11362614
    Abstract: A power conversion apparatus includes a main circuit unit, a control unit, a current sensor, and a half-wave rectifier unit. The control unit includes current frequency calculation units and monitoring units. The current frequency calculation units calculate current frequencies based on at least either the rising timing or falling timing of current detection signals half-wave rectified by the half-wave rectifier unit. The monitoring units monitor the speed of a motor based on the current frequencies calculated by the current frequency calculation units.

  • Publication number: 20210370847
    Abstract: A capturing device has a lens block that includes a lens for focusing light from a subject during a daytime, the subject includes a vehicle. The capturing device further includes an image sensor that captures an image based on light from the subject focused by the lens, and a processor that generates a face image of an occupant riding in the vehicle based on a first number of captured imaged of the subject which are captured by the image sensor at different times. The processor generates the face image of the occupant further based on a second number of captured images in which a luminance value of a region of interest is equal to or smaller than a threshold value among the first number of captured images of the subject.

  • Patent number: 11117529
    Abstract: A capturing camera has a lens block that includes a lens for focusing light from a vehicle as a subject, an image sensor that captures an image based on light from the vehicle focused by the lens, a filter unit that rotatably supports a polarization filter which limits the light from the vehicle received by the image sensor, a sensor that detects a daytime mode or a night mode, a processor that disposes the polarization filter on a front side of the image sensor in the daytime mode, and disposes a band pass filter on the front side of the image sensor in the night mode, and an illuminator that irradiates the subject with IR light in the night mode. The filter unit switchably supports the polarization filter and the band pass filter that transmits the IR light.

  • Patent number: 11102456
    Abstract: A camera generates a first video having visibility lower than a predetermined visibility suitable for a process using a video in a video output apparatus, encodes the generated first video, and transmits the encoded first video, and an adjustment instruction including a parameter for adjusting the visibility of the first video to be equivalent to the predetermined visibility, to the video output apparatus. The video output apparatus acquires the first video and the adjustment instruction, transmitted from the camera, adjusts the visibility of the first video to be equivalent to the predetermined visibility by using the parameter, based on the adjustment instruction, and outputs the adjusted video to an output unit.
