- 摘要：
PROBLEM TO BE SOLVED: To reflect peripheral pixel values when calculating pixel values of defective pixels and at the same time prevent noise from getting smaller than the peripheral pixels.
SOLUTION: An X-ray detection section 2 generates raw image data transmitting through a subject, and an image processing section 7 processes the raw image data and displays an image on a display section 8. Then, a noise retention correction pixel value calculation section 71 of the image processing section 7 weightedly averages the peripheral pixel values using such a coefficient so that the sum of squares of the coefficient of the weighted average is equal to the square of the number of data used for the weighted average, so as to calculate a correction value of the defective pixels.
