Title:
IMAGING DEVICE
Document Type and Number:
Japanese Patent JP2015219444
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To attain an imaging device that can photograph a main subject so as to be a correctly exposed even when taking a flash photograph in a correct exposure condition at luminance of ordinary light.SOLUTION: An imaging device comprises: pre-light emission light metering means that detects a pre-light emission light metering value by a pre-light emission alone as to a plurality of light metering areas prior to photographing; exposure value calculation means that calculates main photography exposure value in main photography from an ordinary light metering value; main light emission-amount calculation means that calculates an amount of main light emission of a flash device in the main photography on the basis of the pre-light emission light metering value; light emission contribution area discrimination means that discriminates the light metering area to which the pre-light emission contributes of the plurality of light metering areas as a light emission contribution area on the basis of the pre-light emission light metering value; light emission contribution area light metering value calculation means that calculates an ordinary light metering value in the light emission contribution area discriminated by the light emission contribution area discrimination means; and correction light emission-amount calculation means that calculates a correction amount of light emission for correcting the amount of main light emission on the basis of difference between the ordinary light metering value in the light emission contribution area and the main photography exposure value.
