Patent ID: 11910089
Assignee: COREPHOTONICS LID.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 10:
11. 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 in one or more directions to direct the Tele folded camera towards a plurality of points of view (POVs) of a calibration chart, each POV associated with a respective OPFE position;
c) capturing a respective Tele image of the calibration chart at each POV, each Tele image having a respective POV aberration in the shape of a non-rectangular tetragon introduced by the position of the OPFE, wherein the calibration chart includes location identifiers that allow to determine the POV for the given OPFE position from the respective Tele image, wherein the calibration chart includes angular identifiers that allow to determine the POV aberration for the given OPFE position from each Tele image;
d) from the respective Tele images of the calibration chart at each POV, deriving calibration data between each POV with its respective POV aberration and the respective OPFE position; and
e) using the calibration data to digitally correct the POV aberration of each Tele image by applying to the Tele image having the POV aberration a geometric transformation related to the position of the OPFE, thereby obtaining a respective POV aberration-corrected image.
