摘要

PROBLEM TO BE SOLVED: To achieve an automatic focusing function suitable for stereoscopic photographing for a television camera and to freely and efficiently correct a difference between left and right focuses.SOLUTION: The stereoscopic lens system comprises: a focus controller 30 configured to perform an automatic focusing operation by using a left lens device 11L, and obtaining a focus lens position corresponding to an automatic focusing resu and a left and right difference correction device 50 for setting an offset value using, as a reference, the focus lens position corresponding to the automatic focusing result. Each time the volume 52 of the left and right difference correction device 50 is operated, a right lens device 11R that does not perform an automatic focusing operation moves the focus lens of this right lens device 11R to a position defined by the total value of the focus lens position corresponding to the automatic focusing result and an offset value that has been set by the volume 52.
