Abstract

PROBLEM TO BE SOLVED: To provide the technology configuring the television camera by which an image of an object is picked up in details even when the length is laterally or longitudinally long. SOLUTION: A charge coupled device(CCD) 1 of a CCD television camera is mounted on a mount board 2. The mount board 2 is supported to a case turnably or rotatably with a CCD drive motor 3. A center of the rotary shaft of the CCD drive motor 3 is in matching with a center of an image pickup face of the CCD 1. Furthermore, the CCD drive motor 3 consists of a motor with encoder or a stepping motor or the like and driven at an optional turning angle. For example, when the length of the object is long longitudinally, the long side of the CCD 1 is picked up by using a position 1d in the longitudinal direction. Moreover, the center of the image face of the CCD is used for a center point to be turned at a prescribed speed and the image is picked up.
