Zusammenfassung:	PROBLEM TO BE SOLVED: To detect a defective pixel or a data missing pixel due to a foreign matter, more accurately by convenient operation.SOLUTION: In data missing pixel detection processing for detecting a defective pixel (pixel injury) occurring congenitally and posteriorly, or a pixel missing data due to a foreign matter, a determination is made whether or not the lapsed time from the start of previous processing is shorter than a predetermined time (step S114). When the lapsed time goes over a predetermined time, the detection level is set to a normal detection level (step S116). When the lapsed time is shorter than a predetermined time, the detection level is set to a high sensitivity (step S118).SELECTED DRAWING: Figure 2 【課題】簡便な操作でより正確に欠陥画素や異物に起因するデータ欠損画素を検出する。【解決手段】先天的および後天的に発生する欠陥画素（画素傷）の検出、または異物に起因してデータが欠損する画素を検出するデータ欠損画素検出処理において、前回の同処理の起動からの経過時間が、所定時間よりも短いか否かを判定する（ステップＳ１１４）。経過時間が所定時間以上のときには通常の検出レベルに設定する（ステップＳ１１６）。経過時間が所定時間よりも短いときには、検出レベルを高感度に設定する（ステップＳ１１８）。【選択図】図２
