Claims (1)
- 撮像素子により体腔内の被観察体像を撮影して得られた撮像信号をデジタル化した、複数の信号レベルで階調表現される映像信号に、直交変調を施してRF信号を生成し、RF信号を電波として送信する電子内視鏡と、電波を受信して、前記RF信号から元の映像信号を復調し、復調した映像信号から内視鏡画像を生成するプロセッサ装置とからなる電子内視鏡システムにおいて、
前記電子内視鏡は、前記映像信号と、前記映像信号の垂直同期信号および水平同期信号の状態を表す同期符号を、映像信号を表す信号レベルと同数の信号レベルで表されるシリアルデータに変換する符号化部であり、前記同期符号はシリアルデータの信号レベルの上下数値で表し、前記上下数値を除くシリアルデータの信号レベルと同じ信号レベルで表される映像信号はそのままシリアルデータの同じ信号レベルで表し、前記上下数値のシリアルデータの信号レベルと同じ信号レベルで表される映像信号を、前記上下数値を除くシリアルデータの信号レベルの最大値および最小値に置換する符号化部を備え、
前記プロセッサ装置は、前記同期符号を検出して、前記映像信号から前記垂直同期信号および前記水平同期信号を分離する同期分離部を備えたことを特徴とする電子内視鏡システム。
