Abstract
【解決手段】 カメラ10から入力された映像信号を動き検出部14で検出し、その検出結果の差分を、画像データの付帯情報として、ハードディスク18に記録する。再生する際には、画像データの付帯情報を基に、設定した範囲で動きがあったかどうかを検出し、動きがあった場合、ハードディスク18に記録された画像データをモニタテレビ23に出力する。
【選択図】 図1
Description
画像記録装置1は、入力カメラ切り替え部11、画像データ入力部12、画像データ圧縮伸張部13、動き検出部14、制御部15、操作部16、データフロー制御部17、ハードディスク(以降、HDとする)18、データI/F部19、通信部20、表示制御部21、および時刻管理部24を備えたものである。
画像データとしてデータフロー制御部17へ出力するものである。また、HD18で記録されている画像データを再生する際には、データフロー制御部17を介してHD18で記録されて、圧縮されている画像データを伸張し、表示制御部21へ出力するものである。
囲)の設定等を行うものである。また、再生モード時には、動き検出を行う検出エリア(範囲)の設定以外にも、動き検出を行う対象物の大きさ等の設定も行うことができる。
1に一時的に保持する(S14)。基本検出部31で保持された基本検出単位毎の比較結果(差分値)は、画像データの付帯情報としてデータフロー制御部17を介してHD18へ記録される(S15)。
ここで、再生する際、ある範囲を指定し、動きがあった時点の映像を検索したい場合には、この差分値を用いて動きの有無を調べ、動きのあった時点の画像データをHD18から読み出せばよいので、従来の画像データ同士を比べる方法に対して、処理するデータ量が少なく、検索を高速に行うことができる。
する。この値は、2値の値ではなく、数値(多値)を用いることによって、動き検出の精度を高めることができる。
