Abstract
A television camera includes an acceleration correction device for correcting for sudden movements of the camera, to prevent blurring of the resulting television picture. The correction device changes the starting point on an image target depending upon the amount and direction of the acceleration. This correction does not occur until the acceleration exceeds a threshold value.
