The present invention relates to a device for controlling a multi-axial point tilt of a camera lens and a method therefor, characterized by controlling a camera lens to move within a common stroke section among respective stroke sections in which the camera lens can move in an axis direction (z-axis) parallel to an optical axis direction at each of three or more axial points, wherein the camera lens is moved to a target position by using a compensation factor that is compensated such that a lens movement distance for each control code is the same.

An actuator assembly (4001) includes a first part (4002), a second part (4004), a bearing arrangement (4003) and a drive arrangement (4005). The bearing arrangement (4003) includes first to fourth flexures (40151, 40152, 40153, 40154) arranged about a primary axis (4009) passing through the actuator assembly (4001). The bearing arrangement (4003) supports the second part (4004) on the first part (4002). The second part (4004) is tiltable about first and/or second axes (4011, 4012) which are not parallel and which are perpendicular to the primary axis (4009). The drive arrangement (4005) includes four lengths of shape memory alloy wire (40101, 40102, 40103, 40104). The four lengths of shape memory alloy wire (40101, 40102, 40103, 40104) are coupled to the second part (4004) and to the first part (4002). The bearing 15 arrangement (4003) is configured to convert lateral force(s) normal to the primary axis (4009) generated by the drive arrangement (4005) into tilting of the second part (4004) about the first and/or second axes (4011, 4012). Each of the first to fourth flexures (40151, 40152, 40153, 40154) has a first end (4016) connected to the first part (4002) and a second end (4017) connected to the second part (4004). Each of the first to fourth flexures (40151, 40152, 40153, 40154) includes a feature (1016) configured to increase a first compliance of that flexure (40151, 40152, 40153, 40154) to displacement of the respective second end (4017) towards the respective first end (4016). The first compliance is less than a second compliance of that flexure (40151, 40152, 40153, 40154) to 25 displacement of the respective second end (4017) parallel to the primary axis (4009).
