Abstract

PURPOSE:To observe an object in three-dimension by turning relatively an image pickup means with respective to a picked-up object, picking up plural frames of a narrow visual angle picture corresponding to a rotary angle and turning a display means in relation to the turning of the pickup means relatively with respect to a viewer. CONSTITUTION:The above device is provided with a display section 1 with a narrow visual angle coupled with a rotary drive section 2 fixed to a housing with an arm through a drive shaft, a recording section 4, a contact power supply section 6, and a rotating speed control section 3 controlling the drive speed and direction of the rotary drive section 2 in matching with the rotating speed of a video image. Then the display section 1 and the recording section 4 are energized from the contact power supply section 6 and a moving picture recorded in the recording section 4 is outputted to the display section 1 repetitively. That is, when the image pickup rotating speed of the picked-up object and the rotating speed of the display section 1 are synchronized at the same speed, only one face of a video image is observed from a direction. When the synchronization or the speed is deviated, the video image is observed as if it were turning at a speed in response to the deviation. When the display means is turned while a picture is being displayed on a two-dimension display face, the picked-up object is observed in three-dimension.
