Zoom dual-aperture camera with folded lens
Zoom digital cameras comprising a Wide sub-camera and a folded fixed Tele sub-camera. The folded Tele sub-camera may be auto-focused by moving either its lens or a reflecting element inserted in an optical path between its lens and a respective image sensor. The folded Tele sub-camera is configured to have a low profile to enable its integration within a portable electronic device.
1. A mobile electronic device, comprising: a camera comprising a Wide sub-camera that includes a Wide lens module and a Wide image sensor and is configured to provide a Wide image, wherein the Wide lens module has a Wide lens symmetry axis along a first optical path between an object side and the Wide image sensor, and a Tele sub-camera that includes a Tele lens module with a height that does not exceed 8 mm, a Tele image sensor and a first reflecting element and is configured to provide a Tele image, wherein the Tele lens module has a Tele lens symmetry axis along a second optical path and comprises a group of 3 to 5 lens elements and wherein the lens elements in the group are designed to have a diameter not substantially exceeding the diameter of an aperture of the Tele sub-camera, wherein the Tele lens symmetry axis is substantially perpendicular to the Wide lens symmetry axis, and wherein the first reflecting element has a first reflecting element symmetry axis inclined substantially at 45 degrees to both the Wide lens symmetry axis and the Tele lens symmetry axis and is operative to provide a folded optical path between the object and the Tele image sensor; and
a processor configured to process the Tele image and the Wide image into an output image.
2. The mobile electronic device of claim 1 , wherein the Tele sub-camera further comprises a second reflecting element, and wherein the Tele image sensor is configured to receive incoming light passing through the first reflecting element, the first lens module and the second reflecting element.
