Description

Camera module Technical Field The following description relates to a camera module. Background With the trend of miniaturization and slimness of portable electronic devices including mobile phones, efforts have been made to reduce the size of components mounted on the electronic devices, and integrated technologies for realizing the respective functions have been continuously researched and developed. For example, camera modules as electronic components are used for camera phones, personal Digital Assistants (PDAs), smart phones, and notebook computers. The camera module may have various additional functions such as Auto Focus (AF) and optical zoom at a relatively low manufacturing cost. The camera module may include a sub-housing equipped with an optical filter and an actuator for implementing additional functions such as auto-focus and optical zoom. The size of the actuator in the camera module increases, which increases the amount of adhesive required to fix the sub-housing, which may cause problems with the adhesive flowing out of the camera module. The above information is presented as background information only to aid in the understanding of the present disclosure. No determination is made as to whether any of the above can be applied as prior art with respect to the present disclosure, and no assertion is made.
