1. A method comprising:
a) providing a Tele folded camera that includes an optical path folding element (OPFE) and an image sensor;
b) tilting the OPFE by a rotation angle in one or more directions to direct the Tele folded camera towards a point of view (POV);
c) capturing a Tele image from the POV, the Tele image having a POV aberration in the shape of a non-rectangular tetragon introduced by the rotation angle of the OPFE; and
d) digitally correcting the Tele image having the POV aberration by applying to the Tele image having the POV aberration a geometric transformation related to the rotation angle of the OPFE to obtain a respective aberration-corrected image, and cropping and scaling the aberration-corrected image to obtain a respective aberration-corrected, cropped and scaled output image that has an output image center (OIC), an output image size and an output image width/height ratio.
