PROBLEM TO BE SOLVED: To obtain a scintillation camera capable of obtaining a homogeneous image having the continuity in a range wider than a visual field width or more of a detector. SOLUTION: The detector is moved step by step with respect to a subject in a first visual field and a second visual field at a prescribed pitch (a moving distance) P (W>P) smaller than the visual field width W of that to collect data of overlapping a visual field directional width of the detector with an area L (=W-P) in a part (the rear end part of the first visual field and the front end part of the second visual field) in the vicinity of an end part. This overlap area L is divided into A and B in the first visual field and A' and B' in the second visual field. The respective divided areas are put in the relationship of A=A' and B=B', and both data on the overlap area L are data obtained from the same part of the subject. The data on an area A' and an area B of a visual field width end part including inaccurate data by the deterioration of homogeneity by a characteristic of the detector of the scintillation camera is eliminated, data on an area A and an area B' being accurate data including no inaccurate data by the deterioration of the homogeniety are joined, and image processing such as image reconstitution is performed to obtain an image of a range not less than the visual field width of the detector.
