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.
