Claims (2)
- 撮像素子と、該撮像素子に入射する光量を制御する露光制御手段と、照明手段及び照明制御手段とを備え、
前記照明制御手段は、前記露光制御手段から入力される信号に基づき、前記撮像素子に入射している光量が前記露光制御手段の絞りを開放してから所定量低下した際に前記照明手段を点灯させると共に、前記照明手段が点灯したことにより前記撮像素子に入射している光量が前記絞りを全開の状態から所定量閉じて減光した際に前記照明手段の発光強さを段階的に制御することを特徴とする照明内蔵型カメラ。 - 前記露光制御手段は、前記撮像素子に入射する光量が低下した際に、第1優先として前記絞りを開け、次いで自動利得調整増幅器の増幅率を上げるように制御することを特徴とする請求項1に記載の照明内蔵型カメラ。
