Abstract
Folded camera modules in which the camera module height is determined by a folded lens module diameter and by the lens module movement in a direction perpendicular to the lens optical axis, and dual-aperture cameras including such folded camera modules. A folded camera module includes OIS and AF actuators having dimensions smaller than the camera module height and therefore not adding to the camera module height.
Claims19
A folded camera module having a respective folded camera module height and first and second ends, comprising:
- a) an optical path folding element (OPFE) configured to fold an optical path from a second direction to a first direction, the first direction being perpendicular to the second direction;
- b) an image sensor positioned at the first end and perpendicular to the first direction;
- c) a lens module carrying a lens having a fixed focal length and a first optical axis parallel with the first direction, the lens positioned between the OPFE and the image sensor;
- d) a first voice coil motor (VCM) operable to provide a first movement of the lens module in the first direction;
- e) a second VCM having a second VCM movement range and positioned at the second end and operable to provide a second movement of the lens module in the second direction;
- f) a third VCM positioned at the second end and operable to provide a third movement of the lens module in a third direction perpendicular to both the first and second directions,
- wherein the first VCM is positioned at a side of the camera module toward the third direction, and wherein the folded camera module height is defined by a diameter of the lens module and by the second VCM movement range, wherein the motion in the first direction is for focus, and wherein the motion in the second and third directions is for optical image stabilization.
