Problems solved by technology

This requires the imaging lens group to have a relatively long rear working distance (the distance between the last piece of the imaging lens group and the photosensitive surface of the image sensor chip), which will increase the design difficulty of the imaging lens group for ultra-thin modules, which is not conducive to improving Imaging performance of the camera module
In addition, the infrared cut filter not only reduces the transmittance of the camera module, but also easily causes the problem of stray light in the process of taking pictures

Abstract

The invention proposes an assembly method for a camera system suitable for a mobile terminal, and the camera system comprises a transparent protection cover plate with an infrared cutoff function, a lens group, and an image sensor chip. The method comprises the step: assembling the last lens of the lens group and the image sensor chip into one body, wherein the lens and the image sensor chip forma cavity. The last lens is used for replacing optical glass and / or infrared filter on an image sensor chip in conventional packaging, and the distance between the last lens and an image sensor is therear working distance of the lens.

Description

technical field [0001] The invention relates to an assembly method of a camera system, in particular to an assembly method of a camera system suitable for a mobile terminal. Background technique [0002] The camera system consists of a camera module and other accessories (such as a protective cover on the camera module). The camera module consists of an image sensor chip and an imaging system. The imaging system consists of an imaging lens group, an infrared filter, and an imaging lens. The group is placed in the lens barrel of the module, and the organic cooperation between the position of the lens barrel and the image sensor chip can obtain high-quality images or videos. Hand-held devices, such as mobile phones, laptops, Pads, etc., are developing towards ultra-thin and high-pixel camera modules. The height of the module is getting lower and lower, and the area array of the image sensor chip is getting bigger and bigger, and the pixel size is getting smaller and smaller. ...
