The resulting images generated in each camera are synchronized to produce one contiguous, synchronized stream of images.

Abstract: This invention has one object to provide radiographic apparatus for acquiring a radioscopic image through superimposing of strip images. The radiographic apparatus allows prevention of blurring in the image with shortened imaging time for acquiring a clearer radioscopic image. According to the configuration of this invention, the FPD-4 is entirely within an imaging range throughout continuous taking of the strip images. In so doing, a minimum movement distance of the FPD-4 may be achieved in continuous taking of the strip images. Even when movement of the FPD-4 deviates from original setting, a range of the deviation may be suppressed to be small, since the movement distance of the FPD-4 is suppressed to be small. Consequently, superimposing of the strip images may realize acquisition of a clearer radioscopic image.

A Fourier transform element provides a one-dimensional Fourier transform on a line orthogonal to a line of a moire patterns appearing in an X-ray image during a use. A peak frequency detection element detects the peak frequency indicating the spatial frequency of the moire pattern on the basis of the results of one-dimensional Fourier transform.

Since the number of pixels in 1-cycle is acquired from the moire pattern in the X-ray image, the line deficiency can be corrected.
