Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A digital photographing apparatus, comprising: a lens unit; an encoder sensor configured to detect a rotational state of the lens unit, wherein the encoder sensor comprises a first sensor and a second sensor that each have an output signal that have different phases than each other; a processor configured to implement: a power supply controller configured to reduce power consumption of the encoder sensor by controlling a supply of power to an input of t…
