[撮像装置の機能構成例]
図1は、本技術の第1の実施の形態における撮像装置100の機能構成の一例を示すブロック図である。
図2は、本技術の第1の実施の形態においてズーム連写により撮像が行われる際の撮像装置100の動作の遷移と、撮像画像の遷移との関係を模式的に示す図である。
図3は、本技術の第1の実施の形態の撮像装置100によるズーム連写と、他の撮像装置によるズーム連写とを模式的に示す図である。
次に、本技術の第1の実施の形態における撮像装置100の動作について図面を参照して説明する。
本技術の第1の実施の形態では、ズーム連写における撮像条件として、露光およびホワイトバランスをズーム連写設定部220が決定する例について説明した。すなわち、本技術の第1の実施の形態では、シャッターボタンの押下を開始したタイミングにおける被写体に応じて、ズーム連写における複数の画像の露光およびホワイトバランスが決定される。
図5は、本技術の第2の実施の形態における撮像装置(撮像装置300)の機能構成の一例を示すブロック図である。
図6は、本技術の第2の実施の形態の撮像装置300において、動体の移動速度に応じて設定されるズーム間隔の一例を示す図である。
図7は、本技術の第2の実施の形態の撮像装置300により動体に応じてズーム間隔が設定される場合のズーム連写と、動体に応じてズーム間隔が設定されない場合のズーム連写とを比較するための図である。
次に、本技術の第2の実施の形態における撮像装置300の動作について図面を参照して説明する。
本技術の第2の実施の形態では、被写体に動体が含まれている場合にズーム間隔を調整する例について説明した。これにより、ユーザーが決定した構図とズーム連写による撮像画像とのズレを低減しつつ、ズーム倍率の変化が大きいズーム連写を行うことができる。しかしながら、場合によっては、被写体に含まれる特定の物体(注目被写体)にのみ注目してズーム連写を行いたい場合がある。このような場合において、注目被写体が動体でないにもかかわらずに注目被写体以外の動体に合わせてズーム間隔を設定すると、注目被写体のサイズが異なる画像を多く撮像したいにもかかわらずに、広いズーム間隔で少数の撮像画像を取得するズーム連写が行われる可能性がある。
図9は、本技術の第3の実施の形態において、ユーザーが注目被写体を指定する際に表示部172に表示される表示画面の一例を示す図である。
次に、本技術の第3の実施の形態における撮像装置の動作について図面を参照して説明する。
本技術の第2および第3の実施の形態では、動体の移動速度に応じてズーム間隔を設定する例について説明した。なお、本技術の第1乃至第3の実施の形態では、ズーム連写を行っている最中に撮像された画像の処理状態を特に考慮せずに説明した。撮像された画像は、撮像装置に設けられているメモリ(例えば、DRAM(Dynamic Random Access Memory))に一端貯められて、順次画像処理された後に保存される。ここで、ズーム連写の最中にメモリが一杯になった場合には、メモリに空きができるまで撮像が停止する。これにより、撮像間隔が広がってズーム倍率の上昇速度が遅くなる場合がある。ズーム倍率の上昇速度が遅くなっても、被写体が静止体の場合には、特に問題は発生しない。しかしながら、動体を撮像している場合には、動体が動いているために、撮像が停止している最中にユーザーが欲する画像の撮像を逃す可能性がある。このため、動体を撮像する場合には、撮像が停止している状態が可能な限り発生しないことが望ましい。
