PURPOSE:To easily recognize the position of an extracted picture in an original picture by displaying a subtraction picture extracting or emphasizing a specific structure stereoscopically together with the original picture or other subtraction picture. CONSTITUTION:Digital picture signals logPA, logSB obtained from two accumulating phosphor sheets A, B are used and a difference signal Ssub obtained by the subtraction processing is recorded at once in a picture file 19. Then the signal is displayed on a three-dimension picture display device 21 through a three-dimension picture constitution circuit 20. On the other hand, a high voltage image logSA and a low voltage image logSb are weighted properly and inputted to an adder circuit 22 to apply arithmetic mean. An arithmetic means signal Sadd is used as density information and inputted to the three-dimension picture constitution circuit 20 and a depth is provided to the density information by using the difference signal Ssub by the subtraction processing and the result is inputted to the three-dimension picture constitution circuit 20 as the depth information. |
