Claim:
1. An image processing method of performing correction processing on received X-ray image data, the method comprising the steps of: receiving a series of image frames captured by a detector; identifying elements of interest by determining whether or not there exists target elements with intensities significantly different from intensities of spatially peripheral elements, in a three dimensional space formed with a space axis and a time axis defined by a series of captured image frames; for each identified element of interest, determining whether the element of interest is a target element, by determining whether the intensity of the identified element of interest is significantly different from intensities of temporal peripheral elements, in a three dimensional space formed with a space axis and a time axis defined by a series of captured image frames; and for each target element, replacing the intensity of the target element with a replacement value calculated from the intensities of temporal peripheral elements, wherein an intensity is significantly different from intensities of peripheral elements if the difference between the intensity and a filtered value of the intensities of peripheral elements exceeds a predetermined threshold, and wherein an element of interest is identified by position information on the space and timing information.
