Description
図3に示すように、電子内視鏡11においては、電子内視鏡11への給電が初期化される(ステップS111)と、電子内視鏡11の第1処理部112は、撮像素子111が撮影した画像データを取得する(ステップS113)。次に、エラー発生判定部117は、第1しきい値th01(画像データのフレーム単位エラーに関しては連続10回、ライン単位エラーに関しては連続1,000回)を用いて、撮像素子111が撮影した画像データのエラーである第1エラーの発生を判定する(ステップS115,S117)。ステップS117で第1エラーが発生したと判定された場合はステップS119に進み、第1エラーが発生していないと判定された場合はステップS113に戻る。
光源装置12においては、画像データ受信部121が、電子内視鏡11から伝送された画像データを受信する(ステップS131)。次に、エラー発生判定部127は、第2しきい値th02(画像データのフレーム単位エラーに関しては連続100回、ライン単位エラーに関しては連続10,000回)を用いて、電子内視鏡11から伝送された画像データのエラーである第2エラーの発生を判定する(ステップS133,S135)。ステップS135で第2エラーが発生したと判定された場合はステップS137に進み、第2エラーが発生していないと判定された場合はステップS131に戻る。
プロセッサ13においては、画像データ受信部131が、光源装置12から伝送された画像データを受信する(ステップS151)。次に、第3処理部132は、第3しきい値th03(画像データのフレーム単位エラーに関しては連続200回、ライン単位エラーに関しては連続20,000回)を用いて、光源装置12から送信された画像データのエラーである第3エラーの発生を判定する(ステップS153,S155)。ステップS155で第3エラーが発生したと判定された場合はステップS159に進み、第3エラーが発生していないと判定された場合はステップS157に進む。
