Hereinafter, some embodiments of the present invention will be described through exemplary drawings. When assigning reference numerals to components in each drawing, identical components are indicated with the same reference numerals as much as possible, even if they are shown in different drawings. Additionally, when describing embodiments of the present invention, if detailed descriptions of related known configurations or functions are judged to impede understanding of the embodiments of the present invention, the detailed descriptions will be omitted.

Additionally, when describing the components of an embodiment of the present invention, terms such as first, second, A, B, (a), and (b) may be used. These terms are only used to distinguish the component from other components, and the nature, sequence, or order of the component is not limited by the term. When a component is described as being "connected," "coupled," or "connected" to another component, that component may be directly connected, coupled, or connected to that other component, but may not be connected to that component or that other component. It should be understood that another component 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. Meanwhile, “optical axis direction” can be used interchangeably with vertical direction, z-axis direction, etc.

The "autofocus function" used below focuses on the subject by adjusting the distance to the image sensor by moving the lens module in the optical axis direction according to the distance to the subject so that a clear image of the subject can be obtained on the image sensor. Defined as a function. Meanwhile, “auto focus” can be used interchangeably with “AF (Auto Focus).”

The “image shake correction function” used below is defined as a function that moves or tilts the lens module in a direction perpendicular to the optical axis to offset vibration (movement) generated in the image sensor by external force.

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

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 sensor base 30. In this case, the light blocking member 50 may shift due to the assembly tolerance of the two filters 31 and 32 and the assembly deviation of the attachment process of the sensor base 30. Meanwhile, when the light blocking member 50 is shifted, there is a high possibility of flare occurring.

In this embodiment, the film-type light blocking member 50 is applied to the lens to improve the reduction in effect caused by the shift of the light blocking member 50 that occurs in the comparative example. Furthermore, this embodiment has the advantage that there is no need to consider the decrease in adhesion of the filters 31 and 32 that occurs due to the application of the light blocking member 50 to the filters 31 and 32 in the comparative example.

In this embodiment, as shown in FIG. 5, light (b) other than light (a) that can be received by the image sensor 20 can be blocked by applying the light blocking member 50. In this embodiment, the possibility of flare due to internal reflection can be reduced by blocking unnecessary light.
