1. An electronic device comprising:
a power supply;
a first sensor configured to acquire first data including information about an external object;
a second sensor configured to acquire second data including image information about the external object; and
processing circuitry,
wherein the processing circuitry includes:
always-on domain processing circuitry configured to determine whether to need to perform face detection or QR code detection based on the first data and to output a first control request signal of requesting a power supply to the second sensor based on a result of the determination; and
not-always-on domain processing circuitry configured to control the power supply in response to the first control request signal such that a power is supplied to the second sensor;
wherein the always-on domain processing circuitry is further configured to perform the face detection or the QR code detection based on the second data, and
wherein the not-always-on domain processing circuitry is configured to control the power supply such that an operating voltage and an operating frequency of an always-on domain are smaller in a standby mode than in an operation mode.
