SHUTTER DEVICE, IMAGING APPARATUS, METHOD FOR CONTROLLING SHUTTER DEVICE, AND CONTROL PROGRAM

PROBLEM TO BE SOLVED: To provide a shutter device capable of high-speed continuous shooting without increasing a required memory capacity.SOLUTION: The shutter device is operable with an electronic front curtain system and includes: a first blade group (4) which moves in a first direction in a first travel pattern so as to shield light incident on an imaging device; a second blade group (5) which moves in a second direction opposite to the first direction in a second travel pattern so as to shield the incident light; scanning means (208) which scans the imaging device in a prescribed scanning pattern to start charge storage per pixel of the imaging device; and control means (204) which controls exposure by combination between scanning of the scanning means and movement of the first blade group and combination between scanning of the scanning means and movement of the second blade group. The second travel pattern corresponds to a travel pattern into which the first travel pattern is inverted with respect to an optical axis.SELECTED DRAWING: Figure 7 【課題】必要なメモリ容量を増加させることなく高速連写が可能なシャッタ装置を提供する。【解決手段】電子先幕方式による動作が可能なシャッタ装置であって、撮像素子への入射光を遮光するように第１方向に第１走行パターンで移動する第１羽根群（４）と、入射光を遮光するように第１方向とは逆の第２方向に第２走行パターンで移動する第２羽根群（５）と、撮像素子の画素ごとに電荷蓄積を開始するために撮像素子を所定の走査パターンで走査する走査手段（２０８）と、走査手段による走査と第１羽根群の移動との組み合わせ、および、走査手段による走査と第２羽根群の移動との組み合わせのそれぞれにより露光制御を行う制御手段（２０４）とを有し、第２走行パターンは、第１走行パターンを光軸に関して反転させた走行パターンに対応する。【選択図】図７
