Title:
IMAGING DEVICE
Document Type and Number:
Japanese Patent JP2017122801
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an imaging device capable of shortening release time lag without influencing a photometric value by correcting an output value of photometric means when making a sub-mirror holder wait by turning a second mirror holder to the position of a first mirror holder in advance.SOLUTION: After focus detection has ended, an imaging device makes a sub-mirror holder in a down position turn toward a main mirror holder in a down position by drive means and wait in a close position with respect to the main mirror holder and changes a correction value for correcting an output value of a photometric sensor when the sub-mirror holder turns in the close position (steps S607, S608). When an imaging element instructs imaging (Yes in step S609), the imaging device locates a mirror unit in an up position by moving the main mirror holder from the down position to the up position by turning the sub-mirror holder from the close position toward the up position by the drive means (step S610).SELECTED DRAWING: Figure 6
