When the camera unit 300 and the display unit 100 are separated from each other by a predetermined distance or more, the connection module 330 according to the embodiment of the present disclosure may be disposed in the ground direction by the elastic body . More specifically, the photographing module 310 and the operation portion coupling module 350 can be coupled through the connection module 330. The imaging module 310, the connection module 330, and the operation unit combination module 350 and the connection module 330 may be pivotally coupled to each other. The photographing module 310 and the connecting module 330 may be combined with each other such that the photographing module 310 is disposed in the direction of the ground through the elastic body. Accordingly, when the display unit 100 is separated from the camera unit 300 by a predetermined distance or more, the photographing module 310 can be arranged to photograph the ground direction according to the restoring force of the elastic body.

For example, the display unit 100 may be tilted from the ground to a predetermined first angle of 90 [deg.]. The operation portion coupling module 350 may be coupled to the coupling module 330 through a hinge. The camera unit 300 can be tilted together with the display unit 100 up to a predetermined second angle of 60 degrees through the hinge. Also, the connection module 330 may be coupled to the photographing module 310 through a spring. Here, the spring may be configured such that the photographing module 310 is disposed in the paper surface direction. Therefore, the display unit 100 and the camera unit 300 can be tilted together by 60 degrees, and the display unit 100 can be gradually separated from the camera unit 300 at an angle of 60 degrees or more. When the display unit 100 is separated from the camera unit 300 by a linear distance of 2 cm or more, the photographing module 310 may be disposed in the direction of the paper according to the restoring force of the spring. The above description of the tilting of the camera unit 300 and the automatic angle adjustment of the photographing module 310 is merely an example, and the present disclosure is not limited thereto.

6 is a diagram illustrating an operation example of a tilting operation of the camera unit according to an embodiment of the present disclosure.

The connecting module according to an embodiment of the present disclosure may include a parallel arm configured such that when the camera unit 300 is tilted, the photographing module 310 is disposed in the direction of the paper. More specifically, the photographing module 310 and the operation portion coupling module 350 can be coupled through the connection module 330. The imaging module 310, the connection module 330, and the operation unit combination module 350 and the connection module 330 may be pivotally coupled to each other. In addition, the photographing module 310 and the connecting module 330 may be coupled to each other such that the photographing module 310 is disposed in the direction of the ground through the parallel arms. Accordingly, when the camera unit 300 is tilted, the photographing module 310 can be arranged to photograph the ground direction through the parallel arm.

Accordingly, the image magnifying apparatus 1000 for a low vision device according to an embodiment of the present disclosure can move forward or backward, or move the camera unit 300 from side to side to enlarge and view a portion desired by the user. The camera module 300 can be moved left and right only by moving the operation module 510 to the left and right, and movement in the forward and backward directions through the moving part 900 is also easy. Therefore, the user can move the camera easily and quickly to a portion desired to be enlarged. Further, since the camera movement in the front, rear, left, and right directions is intuitive, it is easy to learn the operation method and user convenience can be improved.

Further, since the image magnifying apparatus 1000 for a low vision device is mounted on a flat surface, a low vision device can be used without lifting the apparatus, and thus, it can be used for a long time. In addition, it is possible to prevent the camera from shaking through the configuration of the material and the stop module, thereby displaying a more stable screen.

7 is a front view, a rear view, a side view, and a top view of a camera unit according to an embodiment of the present disclosure;

The camera unit 300 according to an embodiment of the present disclosure may have a predetermined height as the focal distance. More specifically, the photographing module 310 can be configured to photograph in a ground direction at a predetermined height from the ground. In addition, the photographing module 310 may set the focal length to a length corresponding to the predetermined height. For example, when the photographing module 310 is arranged to photograph at a height of 5 cm from the ground toward the ground, the focal distance of the photographing module 310 may be fixedly set to 5 cm. The detailed description of the focal length described above is only an example, and the present disclosure is not limited thereto. In another example, the focal length of the photographing module 310 may be automatically set using the autofocusing function.

In addition, the camera unit 300 according to an embodiment of the present disclosure may include a flash module 370 capable of irradiating light to an object to be imaged by the camera unit 300. Here, the flash module 370 may include various lighting devices such as an incandescent lamp, a fluorescent lamp, a halogen lamp, and an LED. The flash module 370 may irradiate the object with light so that the camera unit 300 can photograph the object even in a dark place.

8 is an exemplary view of various forms of a camera portion according to an embodiment of the present disclosure.

The camera unit 300 according to an embodiment of the present disclosure may be formed in various forms based on the combination of the photographing module 310, the connection module 330 and the operation unit combination module 350 and the presence or absence of the flash module 370 . For example, the photographing module 310 may be a circular shape, a concentric circle centered on one point, or a square with rounded corners, and the size may vary in each shape. The above-described description of the photographing module is merely an example, and the present disclosure is not limited thereto.

In addition, the camera unit 300 according to an embodiment of the present disclosure may further include a grounding module (not shown) to which a user's finger can be grounded.
