Document Type and Number:
Japanese Patent JP2015049297
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an exposure controller capable of obtaining apodization effect even when the shutter speed is increased.SOLUTION: The exposure controller includes a diaphragm control section that controls the diaphragm position of an aperture diaphragm from a first diaphragm position to a second diaphragm position within an exposure period based on exposure start timing. At a timing prior to starting an exposure, the diaphragm control section controls the aperture diaphragm to move and accelerate in a direction identical to the movement direction of the diaphragm within the exposure period to get closer to the first diaphragm position.
