Abstract
Description
図1は、実施例1にかかる撮像装置の構成例を示すブロック図である。撮像装置100は、撮像素子101と、画像処理部102と、表示部103と、記録媒体104と、撮影トリガ出力制御部105と、を含む。撮像素子101は、画素領域111と、読出回路112と、を有する。画素領域111は、複数の画素がマトリクス状に配置された画素群である。画素群の各画素は、被写体からの光を光電変換する。画素領域111は、各画素の画素信号をLV(ライブビュー)データまたは静止画データとして読出回路112に出力する。
つぎに、出力タイミングの制御に基づくブラックアウトフリー対応のライブビュー表示例について詳細に説明する。実施例1では、撮像素子101の露光時のフレームレートを120[fps]とし、表示部103に表示させるための間引き処理時のフレームレートを60[fps]として説明する。
図5は、実施例2にかかる撮像装置100のブラックアウトフリー対応のライブビュー表示例1を示す説明図である。図5は、図2と同様、撮影トリガ出力制御部105が存在しない、または、動作しない場合の例である。
図8は、実施例3にかかる撮像装置800の構成例を示すブロック図である。実施例1との相違点は、静止画データ処理部122がLVデータ生成部801を有する点と、撮影トリガ出力制御部105を有しない点である。LVデータ生成部801は、読出回路112が画素領域111から間引きしてLVデータを読み出すのと同様の間引き処理により静止画データを間引きして、LVデータを生成する。LVデータ処理部121は、LVデータ生成部によって生成されたLVデータを表示部103に出力する。
図9は、実施例3にかかる撮像装置800のブラックアウトフリー対応のライブビュー表示例1を示す説明図である。図9では、撮像素子101の露光時のフレームレートを120[fps]とし、表示部103に表示される場合のフレームレートを120[fps]として説明する。図9では、LVデータ生成部801は動作しない。
