Claims (4)
前記撮像素子の欠陥画素のアドレス情報を記憶しておく記憶手段と、
前記アドレス情報に対応する画素を中心として範囲を設定し、前記設定した範囲の画素の出力の補正を行う欠陥画素補正手段とを有し、
前記欠陥画素補正手段は、前記撮像素子の蓄積時間が長くなるほど、前記アドレス情報に対応する画素を中心として前記範囲を広げることを特徴とする撮像装置。 Control means for controlling the accumulation time of the image sensor composed of a plurality of pixels;
Storage means for storing address information of defective pixels of the image sensor;
A defective pixel correction unit that sets a range around the pixel corresponding to the address information and corrects the output of the pixels in the set range;
The imaging apparatus according to claim 1, wherein the defective pixel correction unit expands the range centering on a pixel corresponding to the address information as the accumulation time of the imaging element becomes longer.
前記アドレス情報に対応する画素を中心として範囲を設定し、前記設定した範囲の画素の出力の補正を行う欠陥画素補正工程とを有し、
前記欠陥画素補正工程においては、前記撮像素子の蓄積時間が長くなるほど、前記アドレス情報に対応する画素を中心として前記範囲を広げることを特徴とする画像データの補正方法。 Reading address information of defective pixels of the image sensor from the storage means;
A defective pixel correction step that sets a range around the pixel corresponding to the address information and corrects the output of the pixels in the set range,
In the defective pixel correction step, as the accumulation time of the image sensor becomes longer, the range is expanded with the pixel corresponding to the address information as a center.
