BandCamera は、アガロースゲル電気泳動の画像を撮影・解析するためのアプリです。 ゲルの写真を撮るか、手持ちの画像を読み込むだけで、AI がウェル・マーカーレーン・DNA バンドを自動で検出し、各バンドの塩基長(bp)と DNA 量(ng)を推定します。解析はすべて端末内で行われ、ネットワーク送信やアカウント登録は不要です。 ■ 主な機能 ・iPhone のカメラでゲルを撮影(焦点・露光・ISO のマニュアル調整、複数枚の合成撮影に対応) ・手持ちのゲル画像(PNG / JPEG / TIFF など)の読み込み、左右 90 度回転 ・AI(YOLO/ONNX)によるウェル・マーカーレーン・DNA バンドの自動検出 ・ウェル位置からの傾き補正とレーン推定 ・DNA マーカー(ラダー)の選択、カスタムマーカーの追加 ・マーカー位置の手動補正と再解析 ・各レーン/バンドの塩基長(bp)と DNA 量(ng)の定量 ・解析画像のピンチによる拡大・縮小 ・解析結果の PDF レポート出力 ■ こんな方に ・分子生物学/生化学の研究・教育でゲル電気泳動を行う方 ・PCR 産物や制限酵素処理産物のサイズと量をその場で確認したい方 ・撮影から解析・記録までを 1 台で完結させたい方 ■ プライバシー 撮影・選択した画像は端末内でのみ解析され、外部サーバーへ送信されません。利用者情報の収集も行いません。 ※ 本アプリは研究・教育用途を想定したツールであり、医療診断を目的としたものではありません。
