Problems solved by technology

However, only by adjusting the height of two points, only the slope of the plane can be adjusted, but the height of the entire plane cannot be adjusted, so there is a constraint that the autofocus function cannot be realized at the same time

Abstract

The present invention relates to an apparatus and a method for controlling a multi-axis position slope of a camera lens, characterized in that the camera lens is controlled to move within a common stroke interval among stroke intervals in which the camera lens can move in an axial direction (z-axis) parallel to an optical axis direction in each of three or more axis positions, and moving the camera lens to a target position using a compensation coefficient that is compensated so that the lens movement distance of each control code is the same.

Description

technical field [0001] The invention relates to a camera control system, in particular to a device and method for controlling the multi-axis position slope of a camera lens. Background technique [0002] As the camera module can realize high function and high resolution while being ultra-miniaturized, it is installed in most portable IT devices including mobile phones and tablet PCs. The misalignment between the centerline of the lens group in the camera module and the centerline of the image sensor is called tilt. Since the camera module is manufactured by assembling various parts, the tolerance of each part itself, the assembly tolerance when assembling each part, etc. may cause inclination. [0003] When the tilt exceeds a certain level, the resolution of the captured image will be reduced, and the quality of the image will eventually be reduced. Therefore, a technology for correcting the tilt is required. As a tilt correction technique, there is "camera module and tilt...
