Title:
IMAGING DEVICE
Document Type and Number:
Japanese Patent JP2015219443
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an imaging device that allows an appropriate amount of light emission to make even a subject low in reflectance or subject high in reflectance appropriately exposed in a pre-light emission light adjustment method flash photography.SOLUTION: An imaging device comprises: focus adjustment means that causes a subject in any distance metering area to be focused on; subject distance calculation means that calculates a distance to the subject in an in-focus distance metering area; pre-light emission metering means that detects a pre-light emission metering value by pre-light emission alone as to a plurality of light metering areas prior to main photographing; target light metering value calculation means that calculates a target light metering value to be obtained by causing a flash device to fire the pre-light emission when the subject present at the distance calculated by the subject distance calculation means is a reference subject; light metering value correction means that corrects the pre-light emission metering value of the pre-light emission metering means on the basis of the target light metering value in a light metering area corresponding to the in-focus distance metering area to obtain a post-corrected light metering value; and main light emission-amount setting means that sets an amount of main light emission by the flash device on the basis of the post-corrected light metering value corrected by the light metering value correction means.
