Problems solved by technology

[0027] In the case of the lens shift method, there is a problem that the corrected image differs from the original image as the tilt angle of the camera increases
[0028] In addition, according to the technological trend in recent years, an ultra-thin and ultra-compact camera module is required, but in the ultra-compact camera module, there is a problem of limited space for OIS driving in the module tilt method

Abstract

An embodiment of the present invention relates to a driving apparatus including: a second guide portion; the first guide part is arranged in the second guide part; an optical unit provided in the first guide portion; a first driving portion that is provided in the optical unit; and a second driving portion disposed opposite to the first driving portion, in which the first guide portion includes: a first fixing portion coupled to the second guide portion; a first moving part which is connected to the optical unit; and a first connecting part for connecting the first fixed part to the first moving part, and the optical unit is inclined around the first connecting part by the first moving part.

Description

technical field [0001] This embodiment relates to a drive device, a camera module, and a portable terminal device. Background technique [0002] The camera module photographs a subject and stores it as an image or video, and is mounted on mobile terminals such as mobile phones, notebook computers, drones, and vehicles. [0003] Meanwhile, portable devices such as smartphones, tablets, and notebooks have built-in tiny camera modules, and these camera modules can align the focal length of the lens by automatically adjusting the distance between the image sensor and the lens to perform autofocus (AF )Features. [0004] Camera modules in recent years can perform a zoom function of zooming in or out by increasing or decreasing the magnification of distant objects through a zoom lens. [0005] In addition, recent camera modules employ image stabilization (IS) technology to correct or prevent image shake due to camera movement caused by unstable stationary equipment or user movem...
