Description
ここで最終的に出力される出力映像信号について、図10のPG電圧制御を説明する図および図11の輝度階調調整を説明する図を用いて説明する。
図12は、第2の実施形態の撮像装置の構成例を示すブロック図である。第2の実施形態の撮像装置は、図12に示すように、第1の実施形態の撮像装置に、固体撮像部1を冷却する冷却手段7を追加した構成を備えている。冷却手段7にかかる構成以外は、第1の実施形態と同様であるので、その説明を省略する。
図14は、第3の実施形態の撮像装置の構成例を示すブロック図である。第3の実施形態の撮像装置は、第1の実施形態の撮像装置をカラー化した構成である。カラー化した以外の構成は他の実施形態と同様であるので、その説明を省略する。第3の実施形態の撮像装置では、図14に示すように、固体撮像部1と、暗電流検出手段2と、輝度階調制御手段3と、映像信号検出手段4と、PG電圧制御手段6とを3原色を構成する各色ごとに備えており、さらに、これらの3原色の映像信号検出手段4からの出力が入力される色補正制御手段9および映像信号適正化手段5と、色補正制御手段9からのカラー化された映像信号を検出する色映像信号検出手段10とを備えている。
