发明名称 Camera control for a videophone.
摘要 This camera control has a housing which rotatably accommodates a video camera (10'). It is provided that the camera control exhibits an image comparing unit (14) which derives a correction signal (K) from a comparison of the image currently picked up by the video camera (10') with a reference image stored in a frame buffer (13), that the correction signal is supplied to a camera adjusting unit (15) of the camera control, which derives from the correction signal (K) an adjusting signal (S1-S4) controlling a tracking movement of the video camera (10'), and that the camera control exhibits a positioning device (16) controlled by the adjusting signal (S1-S4) which executes the tracking movement of the video camera (10'). <IMAGE>
