Claim 1:
2. The X-ray imaging device according to claim 1,
wherein the distance evaluation unit outputs first prohibition information when the distance difference is not within the allowable range, and
the extraction unit further includes,
an intensity difference acquisition unit that acquires an intensity difference between first intensity information acquired at the first timing and second intensity information acquired at the second timing,
an intensity evaluation unit that evaluates whether or not the intensity difference is within an allowable range, outputs second permission information when the intensity difference is within the allowable range, and outputs second prohibition information when the intensity difference is not within the allowable range, and
an aspect evaluation unit that evaluates that a variation in a first aspect has occurred in the imaging object when the output of the distance evaluation unit is the first prohibition information and the output of the intensity evaluation unit is the second permission information, and evaluates that a variation in a second aspect has occurred in the imaging object when the output of the distance evaluation unit is the first prohibition information and the output of the intensity evaluation unit is the second prohibition information.
