Dynamic calibration manual focusing method

Abstract

The invention provides a dynamic calibration manual focusing method. The method comprises the following steps: S10: receiving a camera startup instruction and performing camera processing; S20, obtaining basic data information from a manual calibration MF table and an OTP, wherein the MF is defined as an Mf table (a,...,b). , a, b and the value between them are fixed values, reading data in an original manual focus table according to the instruction, and reading the data into a register of an optical sensor of the camera; S30, performing interpolation processing on the basic data information,and establishing a dynamic calibration MF table; S40, performing module consistency correction on the data information in the OTP by using a new dynamic calibration MF table, obtaining the original manual calibration MF table from a memory, and performing movement according to the manual calibration MF table during the manual calibration focusing to correspond to a clearer position. According to the dynamic calibration manual focusing method provided by the invention, the initial value is recorded by reading the old Table, and the OPT data are read to reconstruct a new MF table so as to avoidthe influence of module difference, and thus the manual focusing is more accurate.

Description

technical field [0001] The invention relates to the field of mobile phone camera technology, in particular to a dynamic calibration manual focusing method. Background technique [0002] At present, there are more and more mobile phone functions, and many mobile phones have realized the manual focus function. That is, by adjusting the shaft to manually move the motor to focus. For example, if I need to focus on an object of 10cm, then manually push the motor to a fixed value (focus). And if the object you want to focus on is from far to near, just turn the shaft to move the motor accordingly, then you can always find a clear focus point between far focus and near focus. The moving code (hereinafter referred to as code) is moved according to the manual focus (hereinafter referred to as MF) table (hereinafter referred to as table) on the software. At the same time, in order to be more accurate, this table is generally used for the golden module. derived from actual measureme...

Problems solved by technology

In this case, the effects of the above-mentioned three modules of AB and golden are obviously inconsistent, and golden is just a clearer point; because the difference between A and A is not too large, it may be a little blurry, and the rotation of the shaft can be adjusted to the close focus that A needs. 500code value; while B is very blurry and cannot move to the clear point required by B at all

It is definitely unacceptable for users who use the B module to match their mobile phones.
