Abstract
The disclosure relates to a pan and tilt head (12) for an optical apparatus (10) (e.g. a video camera) which captures or creates an image. The head has a base (19) to be mounted on a support structure (11) (e.g. a tripod), and a body (15) is mounted on the base for pan movement and a platform mounted on the body for tilt movement, about a tilt axis to receive the optical apparatus. The head includes damping means for damping both pan and tilt movement and transducer means (17, 20) for measuring tilt movement of the body about said tilt axis and pan movement of the base to provide measures of unwanted pan and tilt movement for correction of the optical apparatus for said unwanted movement.
