Claims (6)
- 撮像する被写体像を複数の分光色についてそれぞれ電荷を蓄積して撮像信号を出力する撮像装置と、前記撮像信号から得られる画像のホワイトバランスを調整する手段とを備えるデジタルカメラにおいて、前記撮像装置は多数の受光セルを垂直方向及び水平方向に配列し、1つの受光セルは受光素子とスイッチング素子とで構成されるとともに、各受光セルに分光色が割り当てられ、前記受光セルを各分光色ごとに選択して駆動する垂直駆動手段と、各分光色ごとに撮像信号を取り出す水平駆動手段とを備え、前記ホワイトバランス調整手段は、前記垂直駆動手段を制御して各分光色の受光セルの電荷蓄積時間をそれぞれ独立して制御する蓄積時間制御手段を備えることを特徴とするデジタルカメラ。
- 前記撮像装置はMOS型撮像装置であることを特徴とする請求項1に記載のデジタルカメラ。
- 外光の色温度を測定するホワイトバランスセンサを備え、前記蓄積時間制御手段は、当該ホワイトバランスセンサで測定した色温度に基づいて各分光色の電荷蓄積時間を制御することを特徴とする請求項1又は2に記載のデジタルカメラ。
- 前記蓄積時間制御手段は、異なる色温度の光源についてそれぞれ予め設定された電荷蓄積時間に各分光色の電荷蓄積時間を制御することを特徴とする請求項1ないし3のいずれかに記載のデジタルカメラ。
- 各分光色に対応する露出補正ボタンを備え、前記蓄積時間制御手段は、前記露出補正ボタンが操作された分光色の電荷蓄積時間を制御するように構成されていることを特徴とする請求項1ないし4のいずれかに記載のデジタルカメラ。
- 前記露出補正ボタンが操作されたときに、前記蓄積時間を設定するための設定ダイヤルを備えることを特徴とする請求項5に記載のデジタルカメラ。
