Problems solved by technology

[0005] However, the lens moving device consumes a large amount of power, requires additional components for driving such as various support members, magnets, and coils, and also requires a cover glass provided separately from the camera module to protect the above components, resulting in a loss of the lens moving device. Increased overall thickness

Abstract

The present invention provides a camera module comprising: a lens assembly including a plurality of lenses; an image sensor for converting an optical signal transferred through the lens assembly intoan electric signal; a gyroscope (gyro) sensor for outputting a variation-amount signal in response to movement of the lens assembly and the image sensor; a stabilization control unit for determining,in response to the variation-amount signal, a first compensation value for optical image stabilization (OIS) and a second compensation value for electronic image stabilization (EIS); and a movement compensation unit for performing image stabilization according to the first compensation value and the second compensation value.

Description

technical field [0001] The present disclosure relates to camera modules. More particularly, the present disclosure relates to a camera module including a lens capable of adjusting focus using electrical energy. Background technique [0002] A camera module is a module in a camera that captures a still picture or video of a subject. As an example of the camera module, the AF camera module has an auto focus (AF) function which is a function of automatically adjusting focus according to a distance to a subject. [0003] Autofocus is performed by moving a lens module including a plurality of lenses in an optical axis direction using a lens moving device. [0004] The OIS camera module performs a handshake compensation (or Optical Image Stabilization (OIS)) function by moving a lens module including a plurality of lenses in a direction perpendicular to an optical axis using a lens moving device. [0005] However, the lens moving device consumes a large amount of power, require...
