Digital photographing apparatus and method of controlling the same

摘要

A digital photographing apparatus (1) having low power consumption, including a lens unit (100), an encoder sensor (120, 130) configured to detect a rotational state of the lens unit (100), a power supply controller (111) configured to control power supply such that an operation of turning on the encoder sensor (120, 130) to generate a detection signal and an operation of turning off the encoder sensor (120, 130) are repeatedly performed, and a determiner (112) configured to determine the rotational state of the lens unit f(100) rom the detection signal.
