Light entering through the lens 30 from the outside is refracted by the lens 30 and the image is formed on the image sensor 20. At this time, since the light incident from the outside has a predetermined refraction angle, the image sensor 20 and the lens 30 maintain a predetermined distance in order to form an image on the image sensor 20. It may be required to adjust the optical axis of the image sensor 20 and the lens 30 when the image sensor 20 and the lens 30 are coupled via the housing 10. [ The image sensor 20 may be located at one side of the housing 10. At this time, the lens 30 may be positioned on the other side of the housing 10. The image sensor 20 and the lens 30 can be coupled to each other by being fixed to the housing 10. The image sensor 20 may be a digital image sensor 20. For example, a CMOS or CCD sensor. Here, the image sensor 20 means to sense light and convert it into an electrical signal, and is not limited to the above-mentioned configuration or examples.

[ At this time, depending on the mutual angle between the image sensor 20 and the lens 30, the sharpness of the image formed on the image sensor 20 can be changed. This means that the image formed on the right side of the image sensor 20 is clear, while the image formed on the left side is cloudy, and the image formed on the image sensor 20 on the upper side is clear, while the image formed on the lower side is cloudy. That is, the sharpness of the image formed according to the position of the image sensor 20 may be different. The active area of the image sensor 20 has a plane. The image formed on the image sensor 20 through the lens 30 should be located on the plane of the imaging area.

This means that the sharpness of the image formed depending on the position of the image sensor 20 or the lens 30 coupled to the housing 10 may be different. That is, the image sensor 20 and the lens 30 must maintain a predetermined distance, which is called a focal length of the lens 30. This focal distance can be maintained by the image sensor 20 and the lens 30 . It is necessary to adjust the mutual distance between the image sensor 20 and the lens 30 so that the image is clearly formed on the plane of the imaging area of the image sensor 20.
