摘要：
A distance measuring device, or a focus detector, including a plurality of sensors provided in association with a plurality of different areas, and a respective plurality of processing circuits provided in association with the plurality of sensors, to process signals output from the plurality of sensors, where power selectively is supplied only to a sensor(s) and a processing circuit(s) associated with the sensor(s) that correspond to a predetermined area from among the plurality of different areas. The predetermined area may be determined on the basis of the state of a power source (e.g., detected voltage level), the focal length of a shooting optical system, the state of an auxiliary light for irradiating an object, and the like.
