Claims (4)

複数の画素から構成される撮像素子の蓄積時間を制御する制御手段と、
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.
前記欠陥画素補正手段は、前記撮像素子の蓄積時間が所定以上の時間である場合、または前記補正する範囲が所定の範囲に達した場合は、前記欠陥画素を補正する範囲を固定することを特徴とする請求項1に記載の撮像装置。   The defective pixel correction means fixes the range for correcting the defective pixel when the accumulation time of the image sensor is a predetermined time or more, or when the correction range reaches a predetermined range. The imaging apparatus according to claim 1. 前記欠陥画素補正手段は、前記撮像素子の蓄積時間が所定以上の時間である場合、または前記補正する範囲が所定の範囲に達した場合は、前記撮像素子の蓄積時間と同一時間だけ暗時に蓄積を行い、前記暗時に蓄積された撮像素子の出力で減算処理を行うことを特徴とする請求項1に記載の撮像装置。   The defective pixel correcting means stores the dark image for the same time as the storage time of the image sensor when the storage time of the image sensor is a predetermined time or more, or when the correction range reaches a predetermined range. The image pickup apparatus according to claim 1, wherein subtraction processing is performed using an output of the image pickup device accumulated in the dark. 撮像素子の欠陥画素のアドレス情報を記憶手段から読み出す工程と、
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.
