An apparatus to detect a direction or velocity of a movement of equipment by using a single sensor. The apparatus includes a conversion unit that converts sensed information obtained from the single sensor into a voltage value corresponding to the movement of the equipment, a determination unit that determines whether one of a first interrupt and a second interrupt occurs, the first interrupt occurring when the converted voltage value reaches a threshold value and the second interrupt occurring when a preset amount of time passes from a time when the single sensor starts operating, and a calculation unit that calculates one of the direction and the velocity of the movement of the equipment by using voltage information at time s when the first interrupt or the second interrupt occurs and voltage information at a predetermined time before the times when the first interrupt or the second interrupt occurs.

Method and apparatus to detect direction and velocity of movement of equipment by using single sensor

A digital photographing apparatus having low power consumption includes a lens unit, an encoder sensor configured to detect a rotational state of the lens unit, a power supply controller configured to control power supply such that an operation of turning on the encoder sensor to generate a detection signal and an operation of turning off the encoder sensor are repeatedly performed, and a determiner configured to determine the rotational state of the lens unit from the detection signal.
