Description

Camera module Technical Field The following description relates to a camera module. Background With recent trends in miniaturization and slimness of form factors of portable electronic devices such as mobile phones, efforts have been made to reduce the size of components mounted in the electronic devices. Furthermore, techniques for integrating various operations of electronic components are being implemented. By way of example only, a camera module as one of the electronic components may be implemented for smart phones, notebook computers, and vehicles. As image capturing increases, the use of camera modules in portable smartphones is also increasing. In addition, a high performance camera module is also provided in the vehicle to implement an Advanced Driving Assistance System (ADAS) at the front edge, thereby implementing an autopilot function. However, as the camera module has been highly pixelated and miniaturized, there is increasing concern that the camera module may be damaged due to a force applied from the outside.
