<p><P>PROBLEM TO BE SOLVED: To provide a photometric device and imaging apparatus, capable of improving the service life of a battery by suppressing generation of increased power consumption as much as possible in use of a CMOS image sensor as a photometric sensor. <P>SOLUTION: The present invention comprises: a photometric sensor that is switched between an operating state of executing charge storage and a standby state of waiting for charge storage; a sensor drive section that switches the photometric sensor in a standby state when starting charge storage to an operating state and switches the photometric sensor from an operating state to a standby state after reading out stored charges. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
