Claim 0:
1. A camera module comprising:
an optical folding element;
a lens group;
an image sensor;
a front-end anti-jitter component; and
a back-end anti-jitter component, wherein
the optical folding element, the lens group, and the image sensor are sequentially arranged along an imaging light beam transmission direction, wherein
the image sensor has an image capture region, wherein
the front-end anti-jitter component is connected to at least one of the optical folding element and the lens group, and wherein
the back-end anti-jitter component is connected to the image sensor, wherein

the optical folding element is configured to:
fold an optical path of a received imaging light beam; and
transfer the optical path to the lens group, wherein

the lens group is configured to transmit the received imaging light beam to the image sensor, wherein
the image sensor is configured to capture the received imaging light beam in the image capture region, wherein
the front-end anti-Jitter component is configured to perform first jitter compensation on the received imaging light beam, and wherein
the back-end anti-Jitter component is configured to perform second litter compensation on the received imaging light beam, wherein the back-end anti-jitter component comprises:
an image sensor actuating structure; and
a first jitter detection structure, wherein
the image sensor actuating structure is fixedly connected to the image sensor, wherein
the first jitter detection structure has a light sensing region, and wherein
the first jitter detection structure is disposed around the image capture region of the image sensor, wherein

the first jitter detection structure is configured to:
capture the received imaging light beam in the light sensing region; and
detect whether the received imaging light beam captured in the light sensing region jitters, wherein

the first jitter detection structure has a frame rate greater than a frame rate of the image sensor, and wherein
the image sensor actuating structure is configured to:
after the first jitter detection structure detects that the received imaging light beam captured in the light sensing region jitters, drive the image sensor to move, to perform the second jitter compensation on the received imaging light beam.
