PURPOSE:To accurately and rapidly adjust the focuses of right and left optical systems on an object by measuring distances from both right and left optical systems to the object, aligning the optical axes of the optical systems to the object and adjusting the focuses on the object based on the measured results. CONSTITUTION:Light beams from an object O which are made incident from left and right optical systems 1, 2 form respective images on a photoconductive films in left and right image pickup tubes 3, 4. Respective images are converted into electric signals by the photoconductive films in the left and right image pickup tubes 3, 4, the video processing of the electric signals is executed by the left and right image pickup tubes 3, 4 and left and right video signals are outputted from respective output terminals 7, 8. In such case, the photoelectric conversion of the images based upon the left and right image pickup tubes 3, 4 and video processing based upon the circuits 5, 6 are synchronized with each other by the same synchronizing signal outputted from a deflecting circuit 9 and the video signals of the left and right images are synchronously outputted. Consequently, the focuses of both optical systems 1, 2 are automatically adjusted on a required object O by obtaining the video signals as mentioned above. |
