Title:
撮像装置およびその制御方法
Document Type and Number:
Japanese Patent JP5266077
Kind Code:
B2
Abstract:

To surely prevent the occurrence of bright-area-gradation deterioration when photographing a subject at a short distance with flash light.

A flash is previously emitted (pre-emitted) and during a period including at least a part of a pre-emission period, reflection light information (third pre-image) from a subject is captured. On the basis of the reflection light information, the first quantity of required light required for forming a main image is calculated. The flash is mainly emitted (S109) and after start of a main emission period and before the end, charge storage due to a photoelectric transducer is started and/or finished (S110, S111), so that the photoelectric transducer receives light for the quantity of light corresponding to the first quantity of required light (S112-S115). Stored charge is output as a pixel signal, thereby capturing and recording the main image (S116, S117).
