犬や猫の鳴き声やしぐさの音をマイクが捉えたタイミングで自動的にカメラのシャッターを切るアプリです。 [ 周囲の音声解析でカメラのシャッターを自動で切る ] 周囲の音声解析の結果、予め設定した音声を聞き取ったタイミングで、カメラのシャッターを自動的に切ることができます。音声解析の信頼度は、それぞれの音の種類ごとに50%〜100%までの範囲で指定可能です。該当の音声が聞こえている間は連写モードで写真を撮影しますが、ボタン操作で連写動作を止めることが可能です。 ※ 雑踏や群衆などの音は特定の音を聞き取ることができないため”不明な音や未知の音など”という解析結果になります。 [ カメラのファインダー内に分析モニターを表示します ] カメラのファインダー内には、周囲の音を解析した結果を可視化する分析モニターを常時表示します。分析モニターは、ドラッグ操作で表示位置を変更できます。 [ 撮影した写真は写真アプリのライブラリに保存します ] 撮影した写真は、写真アプリのライブラリに保存されます。 [ カメラで撮影した動物などの種類を調べることができます ] カメラで撮影した動物に関する情報を調べた結果を専用シートで閲覧することができます。 [ カメラ機能はシンプル設計です ] カメラには、マニュアル操作によるシャッター、自動シャッターモードの切り替えボタンの他に、フロント/リアカメラの切り替え、フレッシュのオンオフ、撮影した写真のプレビュー画面などを実装しています。

Verdict

The call

On device support there is nothing between them.
