防犯用のカメラは、不審者および不審行為を捉える目的があるため、高解像度な映像が必要になります。
一方で、改札・自動ドアの通過人数などの「状況モニタ」や、寝室や浴室などにおける高齢者や子供の「見守り」といったシーンでは、プライバシーへの配慮も必要となるため、人・モノの有無や動きなどを低解像度でモニタリングすることが求められています。
このたび、それらのシーンで応用可能なセンサのラインアップに、測距イメージセンサ 2製品 (128 × 8画素, 320 × 20画素)と専用ASICを追加しました。
測距イメージセンサは対象物までの距離を測定するセンサで、取得した距離情報から対象物をシルエットでイメージングすることが可能です。
・画素数の異なる2種類を用意 (128 × 8画素, 320 × 20画素)
・近赤外域で高感度を実現 (従来品比)
・外乱光耐性向上 (従来品比)
・小型CSP (Chip Size Package)タイプ
測距イメージセンサ S16443-01WT, S16444-01WT
撮像例 (S16443-01WTを使用した人物までの距離検知)
128 × 8画素のセンサを用いた撮像例や、人数カウント・ジェスチャー検知・見守りシーンを想定した撮像例を紹介しています。
