A fixed focus camera module built-in auto focusing function

Abstract

The invention provides a fixed focus camera module having an auto focusing function. The fixed focus camera module having the auto focusing function includes a signal processing module capable of realizing the auto focusing function. Thus, even a single automatic focusing camera module is not used, the same effect with the real automatic focusing camera module can be obtained. The fixed focus camera module having the auto focusing function includes a lens module focusing light; an image sensor converting object image obtained through the image module into electric signals and outputting the electric signals; a signal processing module receiving and processing the electric signals output from the image sensor to output image signals and adjusting the focus of the lens module automatically; and a display module displaying the image signals output from the signal processing module.

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...

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
