摘要： The invention concerns correcting an error in an estimated pose of a moveable camera. The camera is at least a part of a camera system that generates an output image on the basis of the camera pose. Incremental pose measurements for the camera are taken over time and a pose of the camera using the incremental pose measurements is estimated, the estimated camera pose having an error. A pose correction is determined on the basis of the difference between an absolute pose measurement for the camera and the estimated camera pose. A rate of change in the camera image caused by a change in the camera is monitored. A parameter of the camera system is periodically adjusted based on the incremental pose measurements. The adjustment is further set in order to effect the pose correction so as to correct for the estimated camera pose error and the pose correction is effected at a rate based on the monitored rate of change in the camera image.

摘要： 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.

摘要： The disclosure relates to a rotary drag device having relatively rotatable members one (4) of which has a stack (5) of closely spaced, thin-walled flexible annular plates (20) peripherally mounted thereon to provide annular running faces and a viscous fluid filling the spaces between the plates, and the other (6) of which members has a stack (8) of segmental plates (33) having part-annular running faces interleaved with the annular plates to slide between the plates with relative rotation of the members. Slits (26, 27) in the annular plates permit release of viscous fluid from between the plates as fluid pressure rises ahead of the segmental plates with increasing relative speed between the members. The flexibility of the annular plates allowing the plates to close together accommodating the loss of viscous fluid from between the plates whereby the damping characteristic of the device can vary between viscous drag between the relative running surfaces of the annular and segmental plates at low relative speeds of the members and, with loss of viscous fluid from between the plates, can change to boundary lubrication between the running surfaces of the respective plates at higher relative speeds of rotation of the members.

摘要： A pan and tilt head provides rotation for a T.V., video or cine camera supported on the head in pan and tilt axes. The head has first rotary damping means for controlling pan movement of the head and second rotary damping means for controlling tilt movement of the head. Both rotary damping means comprises a first rotary damper which generates a rotary damping torque which increases at a progressively reducing rate with angular velocity and a second rotary damper which generates a rotary damping torque which increases linearly with angular velocity. For each axis of movement of the head, one of the rotary dampers provides a permanent damping mode and the other rotary damper provides a selectable damping mode. A mechanism is provided for coupling the rotary dampers together in parallel to combine the damping torques imposed on movement of the head when required.
