Abstract

　調光制御部（１７３）は、平均輝度値測定部（１３２）から入力される平均値と基準輝度値とを比較し、取得された画像情報の明るさを判定する。そして、照明部（１２０）の発光時間を比較結果に基づいて算出し、算出した発光時間に基づいて照明部（１２０）の調光制御を行う。またこのとき、算出した発光時間を発光時間（１９１）としてレジスタ（１９０）に格納しておく。一方、送信信号生成部（１３１）は、取得された画像情報を体外に無線送信するための送信信号を生成する。そして、発光時間付加部（１３３）は、制御部（１７０）を介してレジスタ（１９０）から発光時間（１９１）を読み出し、送信信号生成部（１３１）によって生成される送信信号に付加させる。送信処理部（１４０）は、この送信信号を無線送信する処理を行う。
