Title: Camera module

Description:
TECHNICAL FIELD 
     The present embodiment relates to a camera module. 
     BACKGROUND ART 
     In recent years, micro-camera modules have been developed, and micro-camera modules are widely used in small electronic products such as smart phones, notebook computers, and game consoles. 
     As automobiles become more popular among public, micro-cameras are widely used not only in small electronic products but also in vehicles. For example, a black box camera for the protection of a vehicle or objective data of a traffic accident, a rear surveillance camera that enables the driver to monitor the blind spot at the rear of the vehicle through the screen to ensure safety when the vehicle is reversing, a surrounding detection camera that can monitor the surroundings of the vehicle, and the like are provided. 
     The camera may include a lens, a lens holder accommodating the lens, an image sensor for converting an image of a subject collected in the lens into an electrical signal, and a printed circuit board on which the image sensor is mounted. The housing constituting the outer shape of the camera has a structure in which the entire region is sealed in order to prevent contamination of internal parts from foreign substances including moisture. 
     Due to the characteristics of a vehicle that is disposed outdoors, the temperature inside and outside the vehicle forms a variety of distributions depending on the time. For example, in summer, the indoor temperature may be higher than the outdoor temperature, and in winter, the temperature may drop to below zero. Accordingly, condensation including frost may occur in the components including the lens and glass of the camera according to an abrupt temperature change. For this reason, satisfactory image recordings may not be obtained, or may cause a product failure.
