前記イメージセンサによって撮影された前記被写体の画像信号の高域周波数成分を検出する検出手段、
前記高域周波数成分に基づいてフォーカスを調整する調整手段、
前記被写体の明るさが十分であるかどうかを判別する判別手段、および
前記明るさが不十分であるときに前記イメージセンサの駆動速度を低下させる低下手段を備える、ディジタルカメラ。 An image sensor that is driven at a predetermined speed and shoots a subject,
Detection means for detecting a high frequency component of an image signal of the subject imaged by the image sensor;
Adjusting means for adjusting the focus based on the high frequency component;
A digital camera comprising: discrimination means for discriminating whether the brightness of the subject is sufficient; and reduction means for reducing the driving speed of the image sensor when the brightness is insufficient.
前記判別手段は前記露光関連パラメータを所定閾値と比較して明るさを判別する、請求項１記載のディジタルカメラ。 A calculation means for calculating an exposure-related parameter for obtaining an optimal exposure amount based on the image signal;
It said discriminating means discriminates the brightness by comparing the exposure-related parameters with a predetermined threshold value, according to claim 1 digital camera according.
