Abstract: An imaging device includes a light source operating in response to an optical control signal having a predetermined frequency, a sensor including a plurality of pixels, configured to generate an electrical signal in response to a light reception signal output by the light source and reflected from a subject, and a logic circuit configured to generate first raw data of a spatial domain based on the electrical signal, and an image signal processor configured to convert the first raw data into second raw data of a frequency domain, to select low-frequency data of the second raw data within a frequency band lower than a predetermined reference frequency, to apply a predetermined weighting to the low-frequency data to generate weighted data, and to generate a resultant image based on the first raw data and the weighted data.

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.
