1. A camera module, comprising:
an imaging lens, having an optical axis;
a variable through hole mechanism, disposed corresponding to the imaging lens, wherein the variable through hole mechanism is configured to adjust an amount of light into the imaging lens, and the variable through hole mechanism comprises:
a first driving mechanism, comprising at least one first coil and at least one first magnet that are disposed opposite to each other;
an image sensor, disposed on the optical axis, wherein the image sensor is configured to convert imaging light passing through the imaging lens into an image signal;
an image sensor actuating module, configured to move the image sensor along a direction parallel or perpendicular to the optical axis, wherein the image sensor actuating module comprises:
a second driving mechanism, comprising at least one second coil and at least one second magnet that are disposed opposite to each other; and
a flexible printed circuit, electrically connected to the variable through hole mechanism and the image sensor actuating module;
wherein the at least one first coil of the first driving mechanism and the at least one second coil of the second driving mechanism are disposed on the flexible printed circuit;
wherein a height of the flexible printed circuit along a direction parallel to the optical axis is Hf, a height of the imaging lens along the direction parallel to the optical axis is Hi, and the following condition is satisfied:
