  • Patent number: 11861956
    Abstract: In a device (1) for recognizing an external environment of a moving body, an image processing unit (10) generates image data indicating the external environment of the moving body. Using this image data, object data indicating an object around the moving body is generated. At an occurrence of a predetermined event, a control unit (30) records the generated object data in a recording device (35), whereas the image processing unit (10) records, in another recording device (15), the image data corresponding to the object data recorded in the recording device (35). The time information generation unit (40) adds the same time information to the recorded object data and image data.

  • Patent number: 8625730
    Abstract: In a phase locked loop, frequency-divided clocks each of which is given a phase difference of at least one cycle of a feedback clock are inputted to a first phase comparator and a second phase comparator, respectively, which are made to perform phase comparison with a reference clock. Then, outputs of the first and second phase comparators are weighted by a result of the phase comparison of a receive signal and the feedback clock, and phase adjustment of the feedback clock is phase adjusted using the weighted outputs. Thereby, it is possible to lower a frequency of the reference clock and consequently to suppress power consumption.
