Abstract
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.
