摘要：
Problem to be solved: to effectively reduce image quality degradation of an imaging image caused by defective pixels.The medical image processing apparatus 9 includesBased on the pixel level per pixel in the imaging image picked up by the subjectA defect pixel identifying section 921 for identifying defective pixels in an imaging imageThe setting section 941 sets the degree of correction of the defect correction processing to bring the brightness of the defective pixel to the brightness of the discrimination area including the surrounding pixels located around the defective pixels in the imaging image andA defect correcting section 923 for performing defect correction processing according to the degree of correction is provided.The setting part 941 has a larger degree of correction when the difference between the lower limit of the difference between the brightness of the defective pixel and the brightness of the discriminating region is divided into a second range in which the difference between the first range and the first range is greater than the first range, and is greater than in the second range than in the first range .Diagram【課題】欠陥画素を起因とする撮像画像の画質劣化を効率的に抑制すること。【解決手段】医療用画像処理装置９は、被検体を撮像した撮像画像における画素毎の画素レベルに基づいて、撮像画像における欠陥画素を特定する欠陥画素特定部９２１と、欠陥画素の明るさを撮像画像における欠陥画素の周囲に位置する周囲画素を含む判別領域の明るさに近付ける欠陥補正処理の補正度合いを設定する設定部９４１と、補正度合いに応じて欠陥補正処理を実行する欠陥補正部９２３とを備える。設定部９４１は、欠陥画素の明るさと判別領域の明るさとの差の下限値から上限値までの範囲を第１の範囲と第１の範囲よりも差が大きい範囲である第２の範囲とに分けた場合に、差が第１の範囲内にある場合よりも第２の範囲内にある場合に大きい補正度合いを設定する。【選択図】図２
