Problems solved by technology

[0008] Therefore, the conventional auto-focus camera module has problems in that its structure becomes complicated, its price is high, and its processing power is reduced compared with a fixed-focus camera module.
[0021] Therefore, it is difficult to miniaturize the conventional autofocus camera module, so the production cost increases, making it impossible to mass-produce the camera module at a reasonable price

Abstract

The present invention provides a fixed-focus camera module with an auto-focus function, which includes a signal processing unit capable of implementing the auto-focus function, so that even without using a separate auto-focus camera module, it is possible to obtain a camera module similar to a true auto-focus camera module. same effect. The fixed-focus camera module with an auto-focus function includes: a lens unit that gathers light; an image sensor that converts an image of an object acquired through the lens unit into an electrical signal and outputs the electrical signal; a signal processing unit that receives and processing the electrical signal that has been output from the image sensor to output an image signal, and automatically adjusting the focus of the lens unit; and a display unit that displays the image signal output from the signal processing unit.

Description

technical field [0001] The present invention relates to a camera module, and more particularly to a fixed-focus camera module with an auto-focus function, which includes a signal processing unit capable of implementing the auto-focus function, thereby making it possible to obtain the same The same effect as a real autofocus camera module. Background technique [0002] Recently, devices such as mobile devices, notebook computers, and rear surveillance cameras mounted on bumpers of cars have installed camera modules capable of capturing images. Furthermore, camera modules installed in these devices need to be manufactured in a very small size in order to accommodate the miniaturization of mobile devices. [0003] Generally, a camera module installed in a small mobile device includes an image sensor module and a lens module mounted on one side of the image sensor module. The image sensor module includes: an image pickup element; a circuit board electrically connected to the i...
