Title:
IMAGING DEVICE
Document Type and Number:
Japanese Patent JP2015169923
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To solve problems that an electric double layer capacitor is subjected to limitation of applied voltage and application time, and applying high voltage required in imaging of a still image for a long time results in deterioration of capacity, and therefore, when an LED is used as a light emission element of a stroboscopic device, and the electric double layer capacitor is mounted on a camera which uses stroboscopic during imaging of a still image and auxiliary light during AF time, there is a problem of deterioration of capacity of the electric double layer capacitor.SOLUTION: A power storage element is charged to voltage in which a light emission element can light up as AF auxiliary light during starting time, and the power storage element is charged to voltage in which stroboscopic light emission is possible when it is determined that stroboscopic light emission imaging is performed.
