Problems solved by technology

However, due to the space limitation of the camera module and the location of the driving part of the existing OIS technology, the magnets for OIS and the magnets for AF or zoom are placed closely together, resulting in magnetic field interference, so that there is no proper driving of OIS resulting in eccentricity or tilting problem
[0031] In addition, the related OIS technology requires a mechanical drive for lens movement or module tilting, making the structure complex and power consumption increased

Abstract

An embodiment relates to an actuator and a camera module comprising same. The actuator according to an embodiment may comprise: a first circuit board on which an image sensor is disposed; a first housing disposed on the first circuit board; a lens assembly disposed in the first housing; a second circuit board on which a gyro sensor is disposed and which is disposed on a first side portion of the first housing; and a third circuit board for driving the lens assembly. The third circuit board may be disposed on the first side portion of the first housing and include a first region in which a first coil for driving the lens assembly is disposed. The first coil may overlap the second circuit board in a direction perpendicular to an optical axis direction.

Description

technical field [0001] The present embodiment relates to an actuator and a camera module including the actuator. Background technique [0002] The camera module performs a function of photographing a subject and storing it as an image or video, and is mounted on a mobile terminal such as a mobile phone, a laptop, a drone, or a vehicle. [0003] The actuator is a product having a function of quick focusing by moving a lens in the camera module up, down, left, and right, and issues of ultra-small or ultra-thin, low power consumption, and low cost are major technical issues in the actuator. [0004] Such a camera module is used as a mobile camera module or a vehicle camera module. [0005] A mobile camera module is an essential component for taking and storing photos in mobile devices such as smartphones and tablets. The mobile camera module uses an image sensor to convert the light entering the lens into an electrical signal, and outputs the electrical signal to a display de...
