STEREOSCOPIC IMAGE PICKUP DEVICE

摘要

PURPOSE:To attain continuous camera work in real time by changing the degree of optical path change due to an optical path change element in response to a congestion angle among cameras so as to facilitate the angle adjustment with respect to a noticed point between the adjacent cameras. CONSTITUTION:Cameras 21-24 are arranged while whose optical axes are set in parallel. In optical path revision elements 41-44, a liquid having the same refractive index as that of two bases is filled between the two transparent bases and they act like prisms in which the tilt angle of the bases is variable. Actuators 51-54 change the tilt angle of the elements 41-44. The optical axis of the cameras 21-24 is refracted in the direction of a noticed point by the prisms 41-44 having the tilt angle set by the actuators 51-54. The tilt angle of the elements 41-44 is easily and continuously revised in real time by using an electromagnet or a piezoelectric element or the like.
