Abstract
PURPOSE:To correct positional shift of a sub-pixel unit within a short time, by calculating the positional shift quantity between the first and second magnified images and subjecting the same to the correction of positional shift. CONSTITUTION:The mask image obtained by the photographing of an examinee before a contrast medium is mixed in the desired region to be diagnosed of the examinee and the contrast image obtained by the photographing of the examinee after the contrast medium is mixed are respectively stored in a mask image memory 21 and a contrast image memory 22 and subjected to magnifying processing by the first and second magnifying processing parts 24, 25 to be stored in a magnified mask image memory 26 and a magnified contrast image memory 27. The positional shift quantity between the magnified mask image and the magnified contrast image is calculated by a positional shift operation means 28 and subjected to the correction of positional shift by a positional shift correction means 32. Both images corrected in positional shift are processed by a subtraction processing means 35 and subsequently supplied to a CRT display 37 through a D/A converting means 36.
