The first optical module 100 may comprise a sixth lens unit 150 and a seventh lens unit 160. The sixth lens unit 150 and the seventh lens unit 160 may be spaced apart from each other. The sixth lens unit 150 and the seventh lens unit 160 may be overlapped with the second reflecting unit 142 and the first beam splitter 114 in a direction perpendicular to the optical axis. Each of the sixth lens unit 150 and the seventh lens unit 160 may comprise at least one lens. In another modified embodiment of the present invention, each of the sixth lens unit 150 and the seventh lens unit 160 is described to comprise two lenses respectively as an example, but is not limited thereto, and the number of lenses of each of the sixth lens unit 150 and the seventh lens unit 160 may be variously changed.
The sixth lens unit 150 and the seventh lens unit 160 may be moved in a direction perpendicular to the optical axis by a fifth driving unit 152 and a sixth driving unit 162, respectively. Through this, it is possible to implement a zoom mode.
Unlike this, the sixth lens unit 150 and the seventh lens unit 160 may be liquid lenses. In this case, the zoom mode can be implemented by changing the focal lengths of the sixth lens unit 150 and the seventh lens unit 160 without a separate fifth driving unit 152 and sixth driving unit 162.
The first optical module 100 may comprise a fifth driving unit 152 and a sixth driving unit 162. The fifth driving unit 152 may be connected to the sixth lens unit 150, and the sixth driving unit 162 may be connected to the seventh lens unit 160. The fifth driving unit 152 may move the sixth lens unit 150 in a direction perpendicular to the optical axis. The sixth driving unit 162 may move the seventh driving unit 160 in a direction perpendicular to the optical axis.
The second optical module 200 may comprise a second lens unit 210. When the first main body 20 and the second main body 30 are foldable, the second lens unit 210 may be disposed below the first lens unit 110. At this time, the optical axis of the second lens unit 210 and the optical axis of the first lens unit 110 may be aligned. The second lens unit 210 may comprise at least one lens. In a modified embodiment of the present invention, the second lens unit 210 is described to comprise five lenses as an example, but the number of lenses of the second lens unit 210 may be variously changed.
The second optical module 200 may comprise an image sensor 220. The image sensor 220 may be disposed below or at one side of the second lens unit 210. The image sensor 220 may be disposed in a substrate (not shown). The image sensor 220 may be electrically connected to the substrate. For example, the image sensor 220 may be coupled to a substrate by a surface mounting technology (SMT). As another example, the image sensor 220 may be coupled to a printed circuit board by a flip chip technology. The image sensor 220 may be aligned so that the optical axis of the first lens unit 110 and the optical axis of the second lens unit 210 coincide with each other. That is, the optical axis of the image sensor 220, the optical axis of the first lens unit 110, and the optical axis of the second lens unit 210 may be aligned. The image sensor 220 may convert a light irradiated to the effective image area of the image sensor 220 into an electrical signal. The image sensor 220 may be any one among a charge coupled device (CCD), a metal oxide semi-conductor (MOS), a CPD, and a CID. However, the type of the image sensor 220 is not limited thereto, and the image sensor 220 may comprise any configuration capable of converting incident light into an electrical signal.

Unlike this, in a case in which the sixth lens unit 150 and the seventh lens unit 160 are liquid lenses, when the shutter 112 is turned off, and the reflective surface of the second reflecting unit 142 faces the first beam splitter 114, the light that has passed through the fifth lens unit 140 is reflected by the second reflecting unit 142 and sequentially passes through the sixth lens unit 150 and the seventh lens unit 160, and may be reflected from the first beam splitter 114 to be incident on the second lens unit 210. At this time, the optical apparatus 10 may implement a zoom mode.
According to another modified embodiment of the present invention, in the first optical module 100 being disposed in the first main body 20, a first lens unit 110, a fifth lens unit 140, a sixth lens unit 150, and a seventh lens unit 160 are disposed, and a second lens unit 210 is disposed in the second optical module 200 disposed on the second main body 20, thereby configuring one camera module that implements various optical modes, so that there is an advantage in that the size of the optical apparatus 10 can be reduced.

The optical apparatus 1010 may be one among a hand phone, a mobile phone, a smart phone, a portable smart device, a digital camera, a laptop computer, a digital broadcasting terminal, a personal digital assistant (PDA), a portable multimedia player (PMP), and a navigation device. However, the type of the optical apparatus 1010 is not limited thereto, and any device for photographing an image or a picture may be comprised in the optical apparatus 1010.
The optical apparatus 1010 may comprise a main body 1100. The main body 1100 may form the outer appearance of the optical apparatus 1010. A display 1200 may be disposed on one surface of the main body 1100. The main body 1100 may be formed in a hexahedral shape. The main body 1100 may comprise an upper surface, a lower surface, and first to fourth side surfaces connecting the upper surface and the lower surface. At this time, it may be understood that the first side surface 1110 faces the third side surface, and the second side surface faces the fourth side surface.
The main body 1100 may be foldable. Specifically, the main body 1100 may be folded with respect to an imaginary surface parallel to the first side surface 1110 or the third side surface. At this time, the first side surface 1110 or the imaginary surface parallel to the third side surface may comprise an imaginary line 1210 on which the display 1200 is folded.
A display 1200 may be disposed on an upper surface of the main body 1100. The upper surface may face a lower surface. The upper surface of the main body 1100 may be out foldable. Specifically, the upper surface of the main body 1100 may be folded in a downward direction with respect to the imaginary line 1210 on which the display 1200 is folded. When the main body 1100 is foldable, a partial region of the lower surface of the main body 1100 and the remaining region may face each other.
The optical apparatus 1010 may comprise a display 1200. The display 1200 may output an image photographed by the camera module 1300. The display 1200 may be disposed in the main body 1100. The display 1200 may be disposed on one surface of the main body 1100. The display 1200 may be disposed on an upper surface of the main body 1100.
The display 1200 may be out foldable. At this time, the display 1200 may be folded with respect to the imaginary surface on which the main body 1100 is folded. Specifically, the display 1200 may be folded down with respect to an imaginary surface on which the main body 1100 is folded. In addition, the display 1200 may be folded with respect to an imaginary line 1210 parallel to the first side surface 1110 or the third side surface. Specifically, the display 1200 may be folded down with respect to the imaginary line 1210 parallel to the first side surface 1110 or the third side surface. In this case, the partial region and the remaining region of the display 1200 may not face each other.
The optical apparatus 1010 may comprise a cover glass (not shown). The cover glass may be disposed on an upper surface of the main body 1100. The cover glass may be disposed on one side or an upper surface of the display 1200 to prevent damage to the display 1200. The cover glass may be out foldable together with the display 1200.
The optical apparatus 1010 may comprise a camera module 1300. The camera module 1300 may be disposed in the main body 1100. The camera module 1300 may be disposed inside the main body 1100. The lens unit of the camera module 1300 may be disposed on the first side surface 1110 or the third side surface to be exposed to the outside. That is, the surface exposed to the outside of the lens unit of the camera module 1300 may be parallel to the imaginary surface comprising the imaginary line 1210.
The camera module 1300 may be disposed adjacent to a corner region of the main body 1100. For example, the camera module 1300 may be disposed adjacent to a portion connecting the first side surface 1110 and the second side surface of the main body 1100. A subject photographed by the camera module 1300 may be displayed on the display 1200.
The camera module 1300 may be extended from the first side surface 1110 or the third side surface in a direction perpendicular to the imaginary surface comprising the imaginary line 1210. That is, the camera module 1300 may be disposed in a direction perpendicular to the imaginary line on which the display 1200 is folded. Through this, a long stroke required when the camera module 1300 implements a zoom function can be satisfied, and at the same time, there is an advantage in that the thickness of the optical apparatus 1010 can be reduced.
In addition, in an optical apparatus 1010 according to a second embodiment of the present invention, the length W of the first side surface 1110 and the third surface of the main body 1100 may be formed to have a length L longer than that of the second side surface and the fourth side surface. In this case, it is possible to secure a space that can satisfy a long stroke required when the camera module 1300 implements the zoom function.
In a second embodiment of the present invention, even when the main body 1100 and the display 1200 are folded, the subject photographed by the camera module 1300 is displayed on the display 1200, so that the user's convenience can be enhanced.
