Claim 19:
20. A motion encoder according to claim 1, wherein the second part is movably mounted with respect to the first part to change the joint to a third joint condition and the pattern moves relative to the first ICD to a third pattern position as the joint changes between the first and/or second joint condition and the third joint condition, the third pattern position being at least partially outside the field of view of the first ICD, wherein the processing unit is configured to:
determine that the pattern is moving to the third pattern position;
select new image features having a known spatial relationship with respect to the image pattern features to replace the image pattern features; and
determine how the new image features transform between the received images to quantify the position and/or movement of the first part relative to the first ICD.
