Claims (4)
- 補正レンズまたは撮像素子を保持する可動部を駆動して手ブレを相殺する手ブレ補正手段と、
前記可動部の運動をロック時可動範囲内に規制するロック部材とを備え、
前記ロック部材により前記可動部の運動がロックされた状態でレリーズ操作がなされたとき、前記手ブレ補正手段により前記可動部の位置を現位置に保持する
ことを特徴とする手ブレ補正装置。 - 前記可動部は環状フレーム部を備え、前記ロック部材は、前記環状フレーム部の周囲を取り囲むロック環であり、前記環状フレーム部の外周部には複数の突起部が設けられ、前記ロック環の円形内周部には前記複数の突起に対応する複数の凹部が設けられ、前記ロック環は、ロック位置、ロック解除位置の間で可動可能であり、前記ロック位置では前記突起が前記円形内周部に当接してその動きが規制され、前記ロック解除位置では前記突起が前記凹部内にそれぞれ配置され手ブレ補正のための動きが可能となることを特徴とする請求項1に記載の手ブレ補正装置。
- 前記可動部の中心位置ヘ向けた移動が、前記可動部の制御目標位置を漸次前記中心位置に近づけることにより行われ、前記制御目標位置と前記中心位置の距離が単調減少することを特徴とする請求項1または請求項2に記載の手ブレ補正装置。
- 補正レンズを保持する可動部を駆動して手ブレを相殺する手ブレ補正手段と、
前記可動部の運動をロック時可動範囲内に規制するロック部材とを備え、
