Problems solved by technology

[0037] However, when the height of the coil is increased in this way, since the magnetic flux of the magnet is blocked by the coil, there is a technical contradiction as follows: the sensitivity of the Hall sensor disposed inside the coil is weakened

Abstract

A camera module or a camera device according to one embodiment can comprise: a base; a first lens assembly arranged in the base; a first coil unit arranged in the base; a first spacer arranged in the base; and a first position detection sensor arranged on the first spacer. The first spacer comprises a first support unit and a first protrusion protruding from the first support unit, the first position detection sensor is arranged on the first protrusion, and the first protrusion can be arranged in a hollow portion of the first coil unit.

Description

technical field [0001] Embodiments relate to a camera module and a camera device including the camera module. Background technique [0002] The camera module performs a function of photographing a subject and storing it as an image or moving image, and the camera module is mounted on a mobile terminal such as a mobile phone, a laptop, a drone, a vehicle, and the like. [0003] Meanwhile, ultra-small camera modules are built into portable devices such as smartphones, tablet PCs, and notebook computers, and such camera modules can perform an autofocus (AF) function that automatically adjusts the distance between the image sensor and the lens. distance to adjust the focal length of the lens. [0004] In addition, recently, a camera module may perform a zoom function that enlarges or reduces a photographic subject by increasing or decreasing a magnification of a distant subject by means of a zoom lens. [0005] Also, recently, camera modules employ image stabilization (IS) tec...
