An image converter tube 2c and a plurality of image sensors CCDs 1 (eight CCDs 1 here) are provided, and the respective CCDs 1 and image positions in the image converter tube 2c are in one-to-one correspondence. By carrying out at least one of a control to make a shift to a different image position after image formation in one and the same image position for a predetermined number of frames, and a control to make a shift to a different image position in an imaging cycle with a predetermined time interval, various image pickup situations can be accommodated without changing the structure of CCDs 1 per se.
