Embodiment Construction

[0061] Figure 2A A smartphone 200 is exemplarily shown, which includes an STC 202 and a wide-angle camera P204 at zero position. The wide-angle camera 204 is not a scanning camera, and its point of view ("POV W ”) is a device normal N parallel to the smart phone (parallel to the Z axis). The device normal N is parallel (or antiparallel) to a normal with the largest area on the surface of the smart phone 200. The IMU of the smart phone 200 A coordinate system (such as Figure 4A and 4B The IMU460 in, not shown here) can align a coordinate system of the smart phone 200, for example Figure 2A The coordinate system shown in , wherein the three axes of the coordinate system are parallel to the three axes of symmetry of the smartphone 200, so that the Z axis of the coordinate system of the IMU (and the smartphone 200) is parallel to the POV W . The viewpoint of the STC 202 ("POV T ”) pointing to its zero position (“POV T,0 ”), corresponding to Figure 1A The rotation state...

Abstract

A telescopic folding camera for compensating for an undesired rotational motion of a handheld electronic device comprising such a camera, where the compensation depends on the undesired rotational motion and on a viewpoint of the telescopic folding camera.

Description

[0001] Related applications [0002] This application claims the benefit of priority to U.S. Provisional Patent Application Serial No. 63 / 064,565, filed August 12, 2020, the entire contents of which are incorporated herein by reference. technical field [0003] The examples disclosed herein relate generally to digital cameras, and in particular to the correction of images obtained using folded digital cameras. Background technique [0004] Compact digital cameras with folded optics, also known as "folded cameras", are known, see eg co-owned International Patent Application PCT / IB2016 / 057366. In handheld electronic devices such as smartphones, tablets, etc. (also referred to herein as "handheld devices"), a folded telephoto camera is usually part of a multi-camera, accompanied by one or more additional cameras, e.g. An ultra-wide-angle camera and a wide-angle camera. The field of view (FOV) of an ultra-wide-angle camera UW ) is larger than a wide-angle camera that has a F...
