A TV/video camera ( 12 ) converts optical images into electronic image data. A mounting ( 10 ) for the camera has moving and non-moving components to provide movement of the camera in pan and tilt axes and damping means for damping movement in each axis. To remove unwanted movement transmitted to the mounting encoders ( 16,17 ) measure movement between the moving and non-moving parts of the mounting in each axis to indicate intended camera movement, and an electronic gyroscope ( 18 ) measures actual movement of the camera/mounting in the or each axis. A microprocessor ( 20 ) is provided separate from the camera to receive said electronic image data from the camera and input from the encoders and gyroscope to determine the unwanted movement of a camera from the intended and actual movement signals and to modify the image data to remove the unwanted camera movement from the data.
