Beschreibung
Zusammenfassung:	An image processing device or radiation imaging device for generating an image using output data from a detector for detecting a radiation transmitted through an object to be examined, wherein artifacts caused by a gap between an estimated output value and the true output value are reduced when estimating an output value of a defective element of the detector. Correction is performed not only for the output of the defective element but for the output of the surrounding normal elements used for the defective element correction by a blurring process. Additionally, whether or not to perform the blurring process for the surrounding normal elements and the degree of the blurring process are adjusted according to the device conditions, scanning conditions, and the like.
