Abstract
A camera assembly comprises a support structure and an image sensor mounted on a carrier that is suspended on the support structure by at least one plain bearing that allows movement of the carrier and the image sensor relative to the support structure in any direction laterally to the light-sensitive region of the image sensor. An actuator arrangement comprising plural shape memory alloy wires is arranged to move the carrier and the image sensor relative to the support structure for providing optical image stabilisation of the image captured by the image sensor.
Claims30
A camera assembly comprising:
- a support structure;
- an image sensor having a light-sensitive region, the image sensor being suspended on the support structure in a manner allowing movement of the image sensor relative to the support structure in any direction laterally to the light-sensitive region of the image sensor;
- and
- plural shape memory alloy actuator wires in an arrangement capable, on selective driving thereof, of moving the image sensor relative to the support structure in any direction laterally to the light-sensitive region of the image sensor.

A camera assembly comprising:
- a support structure;
- an image sensor mounted on a carrier, the image sensor having a light-sensitive region;
- at least one plain bearing comprising a bearing surface on each of the carrier and the support structure, which bearing surfaces bear on each other so as to suspend the carrier on the support structure and allow movement of the image sensor relative to the support structure in any direction laterally to the light-sensitive region of the image sensor;
- an actuator arrangement arranged to move the image sensor relative to the support structure in any direction laterally to the light-sensitive region of the image sensor.
