PROBLEM TO BE SOLVED: To eliminate an image pickup moire caused by a relative positional relation between a periodic contrast pattern of an image pickup object and image pickup pixels of a solid-state image pickup device. SOLUTION: A solid-state image pickup device 2 of an image pickup system A and a solid-state image pickup device 6 of an image pickup system B image-pickup an image pickup visual field CE of an image pickup object 16 with a periodic contrast pattern via a half mirror 10. An arithmetic processing section 15 calculates a pixel shift quantity in response to the contrast pattern of the image pickup object 16, generates z, y direction moving signals Sz, Sy to shift a position of the image pickup system B in the directions z, y so as to obtain a video signal VB resulting from applying pixel shift to a video signal VA of the image pickup system A. A pixel unit shift correction processing section 13 processes the video signal VB to produce a video signal VB' with a pixel shift quantity equal to or below an image-picked-up pixel size with respect to the video signal VA. The arithmetic processing section 15 applies arithmetic addition processing to gradation value of the video signals VA, VB' for each pixel to obtain a video signal V whose image pickup moire is eliminated.
