Problems solved by technology

[0038] However, in the prior art, the movement of the mobile lens housing requires thrust, and in order to ensure this thrust, the height of the coil needs to be higher than a predetermined height
[0039] However, when the height of the coil is increased in this way, the magnetic flux of the magnet is blocked by the coil, so there is a technical contradiction that the sensitivity of the Hall sensor disposed inside the coil is weakened

Description

technical field [0001] Embodiments relate to a camera actuator, a camera module including the same, and a camera apparatus. Background technique [0002] The camera module performs a function of photographing a subject and storing it as an image or a moving image, and is mounted on a mobile terminal such as a mobile phone, a laptop, a drone, a vehicle, or the like. [0003] Meanwhile, ultra-small camera modules are built into portable devices such as smartphones, tablets, and laptops, which can perform an autofocus (AF) function that automatically adjusts the distance between the image sensor and the lens to adjust The focal length of the lens. [0004] In addition, in recent years, camera modules may perform a zoom function of enlarging or reducing a subject by increasing or decreasing a magnification of a distant subject by means of a zoom lens. [0005] In addition, in recent years, image stabilization (IS) technology has been adopted in camera modules to correct or pre...
