Problems solved by technology
[0004] However, the method of directly blackening the filter has high process requirements and high production threshold, resulting in high cost
Additionally, blackened glass is not interoperable among different optical systems
Furthermore, when packaging, it is easy to hide dirt that is not easy to remove at the joint position (such as the edge) of the blackened layer and the glass

The invention provides an image sensing module and a camera module. The image sensing module comprises a substrate, an image sensor and an extinction layer, wherein the image sensor is configured on the substrate; the extinction layer is at least located on at least a part of surface of a reflector on the substrate, and a sensing area of the image sensor is exposed; the reflector is located on thesurface of one side of the substrate towards the image sensor. Through the image sensing module provided by the embodiment of the invention, the stray light can be effectively inhibited from the source (namely the reflector) of the stray light, thereby effectively reducing the influence on the imaging by the stray light.
Description
technical field [0001] The present invention relates to an optical module, and in particular to an image sensing module and a camera module. Background technique [0002] Image detection modules and camera modules have been used in many fields today, including camera functions of handheld electronic devices such as mobile phones, tablet computers or cameras, monitors, driving recorders, driving or reversing monitors, and even industrial or Medical image systems, etc., are inseparable from image detection modules and camera modules. [0003] In order to improve the imaging quality of the camera module, an optical filter is generally placed between the lens and the image sensor, and the optical filter is generally installed on a hollow bracket. In order to make the effective light from the lens enter the image sensor unobstructed, the area of the filter is usually larger than the effective area of the image sensor in consideration of component tolerances and assembly erro...
