Description

technical field

[0001] Embodiments relate to a camera module and a method of operating the same. Background technique

[0002] The camera module performs a function of photographing a subject and storing it as an image or video, and is installed in a mobile terminal such as a mobile phone, a laptop, a drone, a vehicle, and the like.

[0003] In addition, ultra-compact camera modules are housed in portable devices such as smartphones, tablets, and laptops, and the above-mentioned camera modules can perform an autofocus (AF) function by automatically adjusting the distance between the image sensor and the lens. to align the focal length of the lens.

[0004] The auto focus function is an essential function in the camera module for capturing still images or videos clearly. Regarding the auto focus function, when the position sensor is used to detect the position of the lens barrel in which the magnet is mounted, and a drive signal is supplied to the drive unit based on the de...
