Hereinafter, some embodiments of the present invention will be described with reference to exemplary drawings. In describing the components in the drawings, the same components are denoted by the same reference numerals whenever possible, even if they are displayed on other drawings. In the following description of the embodiments of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the difference that the embodiments of the present invention are not conclusive.

In describing the components of the embodiment of the present invention, terms such as first, second, A, B, (a), and (b) may be used. These terms are intended to distinguish the constituent elements from other constituent elements, and the terms do not limit the nature, order or order of the constituent elements. When a component is described as being "connected", "coupled", or "connected" to another component, the component may be directly connected, coupled, or connected to the other component, It is to be understood that another element may be "connected "," coupled ", or "connected" between elements.

The "optical axis direction" used below is defined as the optical axis direction of the lens module of the camera module. On the other hand, the "optical axis direction" can be used in combination with the up-and-down direction, the z-

The "autofocus function" used below is to focus the subject by adjusting the distance from the image sensor by moving the lens module in the direction of the optical axis according to the distance of the subject so that a clear image of the subject can be obtained with the image sensor Function. On the other hand, "autofocus" can be mixed with "AF (Auto Focus)".

The "camera shake correction function" used below is defined as a function of moving or tilting the lens module in the direction perpendicular to the optical axis direction so as to cancel the vibration (motion) generated in the image sensor by external force.

In this embodiment, by applying a black mask to the lens, the flare phenomenon can be effectively removed.

In the comparative example, the light blocking member 50 is applied to the first filter 31 and the second filter 32 coupled to the integrated type sensor base 30. In this case, the light blocking member 50 can be shifted due to the assembly tolerances of the two filters 31 and 32 and the assembly deviation of the process of attaching the sensor base 30. On the other hand, when the light blocking member 50 is shifted, the flare is likely to occur.

In this embodiment, a film-type light blocking member 50 is applied to the lens to improve the deterioration of the effect due to the shift of the light blocking member 50 in the comparative example. Furthermore, the present embodiment is advantageous in that it is not necessary to consider the deterioration of the adhesion of the filters 31, 32 caused by the application of the light blocking member 50 to the filters 31, 32 in the comparative example.
