  • Patent number: 12244942
    Abstract: A depth sensor for measuring a distance to an object and an image signal processor configured to change a binning mode based on ambient light are provided. A method for operating a depth sensor for measuring a distance to an object includes outputting a pixel signal from at least one depth pixel included in a pixel array, generating ambient light information based on an intensity of ambient light outside the depth sensor, the intensity of the ambient light being measured using the pixel signal, and setting a binning mode of the depth sensor to an analog binning mode or a digital binning mode based on the ambient light parameter value.

  • Publication number: 20200064482
    Abstract: The present invention provides a LIDAR 100 including a correlation signal generation unit 110 for generating two or more different correlation signals, a signal transmission/reception unit 130 for outputting a part of the two or more correlation signals as a transmission signal St, and receive a signal returned by reflecting from a target 140 among the output transmission signals St as a received signal Sr, a delay time adjustment unit 150 for delaying a reference signal by an appropriate delay time using the reference signal Sref, and a delay time decision unit 180 for determining whether a signal obtained by adding the received signal and the delay reference signal together has an SNR higher than a threshold, thus to determine whether the delay time delayed by the delay time adjustment unit 150 is appropriate or not, and a processing unit 190 for confirming characteristics of the target 140.
