OTONASHI(音無)は、シャッター音を鳴らさずに撮影できる、静かなマナーカメラです。 図書館や自習室での勉強メモ、授業や会議の板書、撮影できる美術館の展示、レストランの料理、子どもやペットとの時間—— シャッター音で、その場の静けさを乱したくない場面があります。OTONASHIは、そんな場面でさっと一枚を残すために作りました。 ■ シャッター音が鳴りません ・写真は、シャッター音を伴わない映像の撮影経路から1枚を作る方式で撮影します ・撮った瞬間は、音の代わりに画面の波紋と小さな振動でお知らせします ■ 暗い場所でも、ざらつきを抑える ・撮るたびに連続した6コマから最もくっきりしたコマを基準に選び、ほかのコマを位置合わせして重ねて、暗い場所で出やすいざらつきを抑えます(手ブレでにじんだコマや、動く被写体で重ならないコマは自動で外します) ・超広角カメラのある機種では、被写体に近づくと自動で超広角に切り替わり、近くの物にもピントが合います ■ 迷わない、ひとつの画面 ・アプリを開けばすぐにカメラ。主なボタンは、シャッターと直前の1枚と静寂モードの3つだけ ・タップでピント(iOS 27以降の対応機種では、動く被写体も追い続けます)、長押しでピントと明るさを固定、上下になぞって明るさ、ピンチでズーム ・暗い会場では「静寂モード」で、画面のボタンや文字の明るさを抑えられます ■ 撮影中は、必ず表示します カメラが動いている間は、画面に「カメラ使用中」を常に表示します。この表示を消す設定はありません。 ■ 写真は、iPhoneの中だけに 撮った写真と重ね撮りの処理は、すべてiPhoneの中で完結します。写真が外部に送信されることはありません。設定で「写真」アプリにも保存できます。 ■ 1日20枚まで、そのまま使えます 購入しなくても、1日20枚まで撮影できます(毎日0時に戻ります)。 OTONASHI プレミアム(買い切り・300円)にすると、枚数の制限なく撮影できます。サブスクリプションではありません。機種変更後も「購入を復元」で引き継げます。 ■ ご注意 ・人を撮影するときは、その方の同意と、その場所の撮影ルールを必ず守ってください。撮影が禁止されている場所では使わないでください プライバシーポリシー:https://aiknowledgebase.github.io/ai-pick/otonashi/privacy.html 利用規約:https://aiknowledgebase.github.io/ai-pick/otonashi/terms.html

A moment earlier. Another chance. A pet jumps. A smile changes. You press the shutter a little late. When you take a photo in Silentone, it can offer frames from just before the tap, giving you another moment to choose from. CHOOSE AFTER YOU SHOOT Your original photo is saved as usual. When Silentone finds sharper candidates from just before the shutter, it keeps them in the review box. Keep shooting, then compare the candidates and save the ones you like together. A HEAD START ON PICKING The sharpest candidate is selected first. You decide which expression or movement matters most, and which photos to keep. PHOTOS, MOVEMENT AND VIDEO Take photos, capture movement with Live Photos, or switch to video with sound. Multi-frame stacking combines several frames to reduce noise. Black screen mode covers the camera display to reduce screen light. NO ADS. NO ACCOUNT. Silentone does not upload your photos or videos to its servers. Anonymous usage statistics are off by default and can be enabled in settings. TRY MOMENT RECOVERY Taking photos and recording video are free. You can save a total of 3 recovered photos for free; this allowance does not reset daily. One purchase unlocks unlimited recovered-photo saves, stacking, black screen mode and Live Photos. No subscription. Recovery uses frames captured in Silentone just before the shutter; it cannot recover deleted photos or moments from before you opened the camera. Candidates are not available for every shot and may have lower resolution than the original photo.
