    • The disclosure relates to a method of eliminating unwanted movement from a static or moving image which is captured or created in an optical apparatus. The method comprises determining unwanted movement in the image, providing an image control feature which has a zero reference position and a range over which the control can be varied to counter in the moving or static image said unwanted movement and using said control feature to remove said unwanted movement in a static or moving image. Non- zeroing in the image control to said reference position is monitored and a restoration to the image control is applied to bias the control towards the reference position at a rate which is a function of the speed of movement of the image in the optical apparatus to minimise the effect of the restoration correction on the image.

    • The disclosure relates to a method of stabilising a recorded or projected image in an optical apparatus supported for damped movement in pan and tilt axes. The method comprises, for each axis, monitoring actual movement of the camera using a dynamic sensor; monitoring intended movement input by the operator across the damper using an opto-electronic transducer and determining at time intervals the difference between the actual and intended apparatus movement which represents unwanted movement and applying a correction to counter the unwanted movement. Movement due to-electronic drift in the dynamic sensor and opto-electronic transducers is determined from the residue of the aggregate of said differences between actual and intended movement over a period of time and is used to predict a value for electronic drift for the next difference between actual and intended movement which is taken into account in the difference.
