Embodiment Construction

[0037] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0038] It can be understood that the terms "first", "second", etc. used in this application may be used to describe various elements herein, but these elements are not limited by these terms. These terms are only used to distinguish one element from another element. For example, a first direction could be termed a second direction, and, similarly, a second direction could be termed a first direction, without departing from the scope of the present application. Both the first direction and the second direction are directions, but they are not the same direction.

Abstract

The present application relates to a Hall sensor calibration method and device, electronic equipment, and a computer-readable storage medium. The method includes calibrating the zero drift value of the Hall sensor to obtain a target zero drift value; the zero drift value is a sampling value of the Hall sensor when the camera is in a static state; controlling the camera to move a preset distance, Acquiring a reference sampling value output by the Hall sensor; determining a reference distance based on the target zero drift value and the reference sampling value; calibrating the Hall sensor based on the preset distance and the reference distance, to obtain The compensation value corresponding to the preset distance. The above method and device, electronic equipment, and computer-readable storage medium can improve the calibration accuracy of Hall sensors.

Description

technical field [0001] The present application relates to the field of image processing, in particular to a Hall sensor method, device, electronic equipment, computer-readable storage medium, and an anti-shake method, device, electronic equipment, and computer-readable storage medium. Background technique [0002] With the development of computer technology, there are more and more smart devices. Among these smart devices, the camera function is particularly important. In the process of taking pictures, anti-shake processing is performed on images or videos, so as to capture more accurate and beautiful images, videos, etc. [0003] In order to perform anti-shake processing more accurately, it is necessary to calibrate and calibrate the parameters of each component in the device first. However, the traditional Hall sensor calibration method has the problem of inaccurate calibration. Contents of the invention [0004] Embodiments of the present application provide a Hall ...
