  • Patent number: 10656271
    Abstract: A light emitting element emits a modulated light modulated in a pattern having a repetitive period toward a space. A driving unit drives the light emitting element. A light receiving element distributes charges corresponding to an incident light containing a reflected light obtained by reflecting the modulated light on an object to storage capacitors and stores the distributed charges.

  • Publication number: 20190195991
    Abstract: In a distance measuring apparatus, an irradiating unit irradiates a measurement region with a pattern light comprised of first and second luminous patterns. The second luminous pattern has a relatively low intensity lower than the intensity of the first luminous pattern. A light receiving sensor receives, for each pixel, a return light component based on reflection of the pattern light by a target object. A measurement controller determines whether an intensity of each return light component received by the corresponding pixel satisfies a measurement condition, and obtains, as effective distance information, at least one distance value of at least one pixel of the light receiving sensor when it is determined that the intensity of the return light component received by the at least one pixel satisfies the measurement condition.
