- a warning for prompting the same size display such as “If the display of the same size cannot be performed, the presence or absence of moire or false color cannot be confirmed accurately” can be displayed on the LCD (warning unit) 60.
- a similar warning may be generated by sound from a speaker (warning unit) (not shown). Or you may generate
- the lens or image sensor 50 that forms a part of the photographic lens 32 is driven in the direction orthogonal to the optical axis to perform vibration isolation, and therefore the vibration isolation unit is shaken or hit against a driving end point to vibrate. If this is generated, the number of parts will not increase.
- the reason why the presence / absence of moiré or false color cannot be accurately performed unless the LPF-on and / or LPF-off-captured images are displayed at the same magnification is as follows. That is, in the reduced display, pixels are thinned and displayed, and the appearance of moire and false colors may change or may not occur.
- the photographer can accurately determine the state of occurrence of moire or false color. In this way, when the photographer operates the operation button, the LCD 60 can display the LPF-on-captured image and / or the LPF-off-captured image at the same magnification. It is possible to accurately grasp the occurrence of moiré and false color from the photographed image, and to accurately confirm the effect of removing moire and false color from the LPF-on photographed image displayed at the same magnification.
- the display control unit (enlarged display control unit) 120 when displaying the LPF-on captured image on the LCD 60 in an enlarged manner, forcibly displays the LPF-on captured image at the same magnification, and displays the LPF off-captured image on the LCD 60 in an enlarged manner.
- the LPF off-captured image can be enlarged and displayed while changing the enlargement magnification without being limited to the same magnification display.
- the display controller 120 magnifies and displays the same corresponding part of the photographed image before and after the switching.

2回目の撮影において、ローパスセレクタ撮影制御部110は、イメージセンサ50の駆動範囲ならびにLPF効果を上記表1の「TYPE1(小)」に設定して、像振れ補正装置70によりイメージセンサ50をLPF駆動させて光学的なローパスフィルタ効果を得た状態でイメージセンサ50による画像信号を記録する(得る)LPFオン撮影を実行する。
3回目の撮影において、ローパスセレクタ撮影制御部110は、イメージセンサ50の駆動範囲ならびにLPF効果を上記表1の「TYPE2(大)」に設定して、像振れ補正装置70によりイメージセンサ50をLPF駆動させて光学的なローパスフィルタ効果を得た状態でイメージセンサ50による画像信号を記録する(得る)LPFオン撮影を実行する。
このように、ローパスセレクタ撮影制御部110は、最初の1回目の撮影において、LPFオフ撮影を実行し、その後の2、3回目のLPFオン撮影において、イメージセンサ50の駆動量および光学的なローパスフィルタ効果を段階的に大きくしながら2回の撮影を実行する。
以上の「LPFブラケット撮影」によって得られた3枚の撮影画像は、LCD60に表示され、画像メモリ65に記憶される。
1回目の撮影において、ローパスセレクタ撮影制御部110は、イメージセンサ50の駆動範囲ならびにLPF効果を上記表1の「TYPE2(大)」に設定して、像振れ補正装置70によりイメージセンサ50をLPF駆動させて光学的なローパスフィルタ効果を得た状態でイメージセンサ50による画像信号を記録する(得る)LPFオン撮影を実行する。
2回目の撮影において、ローパスセレクタ撮影制御部110は、イメージセンサ50の駆動範囲ならびにLPF効果を上記表1の「TYPE1(小)」に設定して、像振れ補正装置70によりイメージセンサ50をLPF駆動させて光学的なローパスフィルタ効果を得た状態でイメージセンサ50による画像信号を記録する(得る)LPFオン撮影を実行する。
3回目の撮影において、ローパスセレクタ撮影制御部110は、イメージセンサ50の駆動範囲ならびにLPF効果を上記表1の「OFF」に設定して、像振れ補正装置70によりイメージセンサ50をLPF駆動することなく光学的なローパスフィルタ効果を得ない状態でイメージセンサ50による画像信号を記録する(得る)LPFオフ撮影を実行する。ただし、像振れ補正装置70によるイメージセンサ50の像振れ補正駆動を行うことはある。
このように、ローパスセレクタ撮影制御部110は、最初の1、2回目のLPFオン撮影において、イメージセンサ50の駆動量および光学的なローパスフィルタ効果を段階的に小さくしながら2回の撮影を実行し、その後の3回目の撮影において、LPFオフ撮影を実行することができる。
以上の「LPFブラケット撮影」によって得られた3枚の撮影画像は、LCD60に表示され、画像メモリ65に記憶される。
あるいは、表示制御部120は、LCD60にLPFオン撮影画像、及び/又は、LPFオフ撮影画像を拡大表示させる場合において、当該LPFオン撮影画像、及び/又は、LPFオフ撮影画像が等倍表示されていないときに、例えば、「等倍表示しないとモアレや偽色の有無の確認が正確に行えません」といった等倍表示を促すための警告をLCD(警告部)60に表示させることができる。併せて、同様の警告を図示しないスピーカー(警告部)から音声により発生させてもよい。あるいは、同様の警告をLED点灯や振動により発生させてもよい。本実施形態では、撮影レンズ32の一部をなすレンズまたはイメージセンサ50を光軸直交方向に駆動して防振を行っているので、その防振ユニットを揺らしたり駆動端点にぶつけたりして振動を発生させれば、部品点数が増えることはない。
ちなみに、LPFオン撮影画像、及び/又は、LPFオフ撮影画像を等倍表示しないと、モアレや偽色の有無が正確に行えない理由は次の通りである。すなわち、縮小表示だと、画素を間引いて表示することになり、モアレや偽色の出方が変わったり出なくなったりすることがあるからである。これに対し、LPFオン撮影画像、及び/又は、LPFオフ撮影画像を等倍表示すれば、撮影者がモアレや偽色の発生状況を正確に判断することが可能になる。
このように、撮影者が操作ボタンを操作することにより、LCD60にLPFオン撮影画像、及び/又は、LPFオフ撮影画像を等倍表示させることができ、撮影者は、等倍表示されたLPFオフ撮影画像によってモアレや偽色の発生状況を正確に把握し、等倍表示されたLPFオン撮影画像によってモアレや偽色の除去効果を正確に確認することができる。
これにより、撮影者が、LPFブラケット撮影によって得た複数枚の画像を拡大して見比べるときに、モアレや偽色の除去状態を確認しやすくなる。
これに対し、同様の場合に、ローパスセレクタ操作スイッチ(第1の切り替え手段)82による「LPFブラケット撮影モード」の設定を優先する態様も可能である。この態様では、操作スイッチ(第2の切り替え手段)80による撮影モードの設定を受け付けず、またはこれを無効とする。この態様におけるデジタルカメラ10の動作は、図8、図9のフローチャートに示した動作と同じである。
