1. An optical lens module with a central axis, comprising:
an operating element including an annular wall surrounding the central axis with a visual side and an image source side, and a storage space enclosed by the annular wall;
a first lens unit disposed in the storage space and including a first lens barrel and a first lens group disposed in the first lens barrel;
a second lens unit disposed in the storage space and including a second lens barrel and a second lens group disposed in the second lens barrel;
a holder disposed on an image source side of the second lens unit;
an image source element disposed on the holder;
an image processor electrically connected to the image source element, and including correction data of image quality and an image signal; and
a detection unit electrically connected to the image processor to provide a feedback signal;
wherein the first lens unit and the second lens unit are arranged in order from the visual side to the image source side of the central axis; when the operating element is actuated, the operating element drives the first lens unit or the second lens unit to move along the central axis to change a distance between the first lens unit and the second lens unit along the central axis, the detection unit generates and transmits the feedback signal to the image processor, and then, the image processor obtains the correction data of image quality according to the feedback signal and provides the correction data of image quality to the image source element.
