Dual-aperture zoom digital camera with automatic adjustable tele field of view

1. A digital camera comprising:

a) an upright Wide camera configured to provide a Wide image with a Wide image resolution, the Wide camera comprising a Wide image sensor and a Wide lens with a Wide field of view (FOV W );

b) a folded Tele camera configured to provide a Tele image with a Tele image resolution higher than the Wide image resolution, the Tele camera comprising a Tele image sensor and a Tele lens with a Tele field of view (FOV T ); and

c) a rotating optical path folding element (OPFE) operative to provide a folded optical path between an object or scene and the Tele image sensor, wherein rotation of the OPFE provides a movement of FOV T relative to FOV W ,

wherein the Wide image sensor has a substantially rectangular shape defined by a height H W and a width W W , wherein the Tele image sensor has a substantially rectangular shape defined by a height H T and a width W T , wherein a height to width ratio H W /W W or H T /W T is smaller than 1, and wherein the Wide and Tele image sensors are in orthogonal planes and with heights H W and H T orthogonal to each other such that FOV T is rotated at 90 degrees to FOV W .

2. The digital camera of claim 1 , wherein the movement of FOV T relative to FOV W is performed in a scanning mode that provides a plurality of adjacent Tele FOVs within FOV W .

3. The digital camera of claim 1 , wherein the rotation of the OPFE has a range of up to ±15 degrees around a zero OPFE position in which FOV T is centric to FOV W .

4. The digital camera of claim 1 , included in a host device having a user interface for operating the digital camera, the user interface comprising a screen configured to display at least one icon and an image of the object or scene acquired with at least one of the Tele and Wide cameras and to display a frame defining the FOV T within FOV W , wherein the frame defining FOV T bounds a Tele image.

5. The digital camera of claim 1 , configured to perform autonomous FOV T tracking.

6. The digital camera of claim 5 , wherein the digital camera is further configured to fuse a Wide image acquired during the autonomous FOV T tracking with at least one Tele image acquired during the autonomous FOV T tracking to form a composite image.

7. The digital camera of claim 6 , wherein the fusion is performed by the camera or in a cloud environment.

8. The digital camera of claim 2 , wherein Tele images representing the plurality of adjacent Tele FOVs are stitched together to form a stitched Tele image used in fusion with the Wide image.

9. The digital camera of claim 8 , wherein the stitching and/or the fusion is performed in a cloud environment.

10. The digital camera of claim 5 , wherein the at least one Tele image includes a plurality of consecutive Tele images stitched together to form a stitched Tele image used in a fusion procedure with the Wide image to provide a composite image.

11. The digital camera of claim 10 , wherein the fusion is performed by the camera or in a cloud environment.

12. The digital camera of claim 5 , wherein the digital camera is further configured to form a composite video stream in which each frame is based on either a processed Wide image or a processed Tele image, the processed Wide and Tele images based on respective Wide and Tele images which are acquired during the autonomous FOV T tracking.

13. The digital camera of claim 1 , included in a smartphone.

14. The digital camera of claim 4 , wherein the host device is a smartphone.
