US 9,319,574 B2 · Camera lens assembly

Abstract

A camera lens assembly is provided. The camera lens includes a movable Auto Focusing (AF) unit configured to move back and forth in a direction of an optical axis of an image sensor, and a movable Optical Image Stabilization (OIS) unit installed on the movable AF unit and configured to move back and forth in the direction of the optical axis together with the movable AF unit. The movable OIS unit floats in a direction orthogonal to the optical axis on the movable AF unit. The camera lens assembly simplifies the construction while implementing both the auto focus function and the optical image stabilization function. As a result, the camera lens assembly is advantageous for miniaturization and may improve reliability.
