Abstract

　ヘッド分離型カメラ（１）のカメラヘッド（２）は、三つの撮像素子（５）ごとのブラックバランスの調整値ＯＢＲ、ＯＢＧ、ＯＢＢを記憶する調整値記憶部（９）と、ブラックバランスの調整値ＯＢＲ、ＯＢＧ、ＯＢＢに基づいて各映像信号の黒レベルが略同じレベルになるようにブラックバランスを調整するブラックバランス調整回路（８）を備える。ブラックバランス調整回路（８）によってブラックバランスを調整した各映像信号が、カメラヘッド（２）からカメラコントロールユニット（３）へ伝送される。これにより、カメラヘッド、カメラケーブル、カメラコントロールユニットの組合せを替えてもブラックバランスの再調整を行う必要がないヘッド分離型カメラが提供される。
