Abstract

A miniature camera comprises a support structure having an image sensor mounted thereon, a lens holder holding a lens arranged to form an image on the image sensor, and an actuator arranged to drive movement of the lens holder relative to the image sensor, the actuator including conductive components capable of conducting a pulse width modulation drive signal for driving the actuator. For providing electro-magnetic screening, a screening element formed by plural layers of material is located inside the conductive components of the actuator around the optical axis. The screening element improves the reduction of noise in the captured image.
