Adjustment and application method for tilting compensation control of lens of automatic focusing camera module

Abstract

The invention discloses an adjustment and application method for the tilting compensation control of a lens of an automatic focusing camera module. In the adjustment process, a system will find out the needed tilting compensation control and store relevant data to a storage device, after adjustment and when the camera module is used, an actuator controller will read the data and use the data, and the purpose of tilting compensation is achieved. As relevant actuator control is changed at different lens strokes (or focusing positions), the tilting angle of the lens is decreased, the tilting angles at the different positions are considered, and the static and dynamic tilting angles can be effectively decreased. In addition, the adjustment process is the full-automatic adjustment process, so that manpower needed in the mass production is reduced effectively, the operating cost is lowered, the frequency of the quality problem caused by manual errors can also be reduced, the operating cost is further lowered, and the product consistency is improved. According to the method, the needed space is small, cost is low, and mass production is facilitated.

Description

technical field [0001] The invention discloses a debugging and application method of a mobile phone lens, in particular a debugging and application method of lens tilt compensation control of an auto-focus camera module, which can quickly and accurately debug an auto-focus camera module capable of controlling lens tilt, Achieve the effect of lens tilt compensation. Background technique [0002] Nowadays, the technology of auto-focus camera modules is quite mature and extensive, especially the resolution of image sensors is getting higher and higher. In high-end mobile phones, image sensors with more than 10 million pixels are very common. As the resolution of the image sensor becomes higher and higher, the maximum allowable lens tilt angle becomes smaller and smaller. When the tilt angle of the lens exceeds the maximum allowable lens tilt angle, the edges of the imaging image may be blurred, resulting in a decline in product quality, or the entire module is unqualif...

Problems solved by technology

[0005] Aiming at the above-mentioned disadvantages of the lens in the prior art that the large production error caused excessive static tilt angle and dynamic tilt angle, the present invention provides a debugging method for lens tilt compensation control. During the debugging process, the system will Find out the required tilt compensation control and store the relevant data in the storage device. After debugging, when the camera module is used, the actuation controller will read the data and use it to achieve tilt purpose of compensation
