Electronic device and method for compensating for depth error according to modulation frequency

A method of operating an electronic device, the method comprising:

• receiving a distance measurement input;
• identifying whether a communication circuit of the electronic device is activated in response to the distance measurement input;
• determining that, in response to identification that the communication circuit is activated, a first frequency distinguished from a frequency used by the activated communication circuit is a frequency of light emitted among configured frequencies;
• acquiring information on a distance between the electronic device and an external object, based on a reflected light of the emitted light of the first frequency;
• and
• acquiring corrected distance information by applying an offset value for a reference frequency of the first frequency to the acquired distance information.

An electronic device comprising:

• a communication circuit,
• a light source configured to emit lights of configured frequencies,
• an image sensor configured to acquire reflected lights of the emitted lights,
• a memory configured to store offset values for reference frequencies of the respective configured frequencies, and
• a processor configured to:
• receive a distance measurement input,
• identify whether the communication circuit is activated in response to the distance measurement input,
• determine that, in response to identification that the communication circuit is activated, a first frequency distinguished from a frequency used by the activated communication circuit is a frequency of the emitted light among the configured frequencies,
• calculate a distance between an external object and the electronic device on the basis of a reflected light of the emitted light of the first frequency, and
• acquire distance information by applying calibration data for the first frequency to the calculated distance.
