Abstract

The invention provides a camera module which comprises a circuit board, a photosensitive chip and a lens base, the photosensitive chip and the lens base are arranged on the circuit board, the photosensitive chip comprises an imaging area and a non-imaging area, and the imaging area comprises a pixel array formed by a plurality of pixel units. The image pickup group module further comprises a microlens array, the microlens array is attached to the photosensitive chip and connected with the non-imaging area, the microlens array comprises a plurality of single microlenses, the single microlenses are connected with one another, and each single microlens covers at least one pixel unit in the pixel units in the pixel array. According to the camera module provided by the invention, the height of the camera module can be controlled within a certain range, and the ultrathin camera module is realized.

Description

Technical field [0001] The present application relates to the technical field of optical equipment, and more particularly to an imaging module based on a microlens array and a manufacturing method thereof. Background technique [0002] The general fixed-focus imaging module is mainly composed of complementary oxidized metal semiconductor photosensitive chips (CMOS), optical imaging lens, mirror, circuit board, the height of its imaging module is the thickness of the wiring board, thickness, and photosensitive chips. And the sum of the optical length (TTL) of the imaging lens. The height change of the imaging module mainly depends on the change in optical length (TTL) of the imaging lens. Since there is a high quality requirement for the imaging effect of the camera module, it is difficult to reduce the optical length of the imaging lens (TTL), so the camera mode The height of the group is also difficult to do so much, generally between 3.5mm to 9.0 mm. [0003] The imaging lens o...
