The photo sensor may be stacked on the display element, which is configured to scan the movement of the sensing object in proximity to the touch screen. More specifically, the photo sensor mounts a photo diode and a transistor (TR) in a row / column and scans contents mounted on the photo sensor by using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor calculates coordinates of the sensing object according to the amount of light change, and thus, the position information of the sensing object can be obtained.

3A and 3B, the stationary auxiliary body 221 further includes a wire 2212 penetrating the side surface. The wire 2212 is made of a material which can be bent freely according to the direction in which the force is applied. As shown in FIG. 3B, when the surface is rugged and difficult to fix to the outside through the adhesive part 2211, the wire 2212 may be wound around an external object to fix the camera module 200 in one place.

On the other hand, the movable auxiliary body 222 means an auxiliary body mounted on the main body 210 for the purpose of changing the position of the camera module 200 with time.

4A-4B show perspective views of the movable aid 222 according to one embodiment. 4C illustrates a state diagram of use of the movable auxiliary body 222, according to an exemplary embodiment.

4A to 4B, the movable auxiliary body 222 (hereinafter, referred to as a first movable auxiliary body 222a) in the present embodiment may be a device capable of flying with a rotating body. In this case, the first movable auxiliary body 222a has a central portion 2225 in the shape of a rod. One end of the central portion 2225 is provided with a recess 2221 recessed to correspond to the outer shape of the main body 210, the other end is connected to the rotating body 2222. The main body 210 may be inserted into the recess 2221 to be coupled to the first movable auxiliary body 222a. On the other hand, the first movable auxiliary body (222a) may be made of a urethane material in order to minimize the damage caused from the external impact.

The first movable auxiliary body 222a may or may not include a separate power generator (not shown). 4C illustrates a state of use of the first movable auxiliary body 222a when the first movable auxiliary body 222a includes a separate power generating unit. In this case, the first movable auxiliary body 222a may photograph an object on the ground while flying in the air like an unmanned aerial vehicle.

In addition, when the first movable auxiliary body 222a does not include a separate power generating unit (not shown), when the first movable auxiliary body 222a is tossed up by an external force, the wings forming the rotating body The first movable auxiliary body 222a slowly descends while being unfolded perpendicularly to the falling direction. Camera 230 may be photographed while descending.

5A-5B show perspective views of a movable aid 222 according to another embodiment. 5C also shows a state diagram of use of the movable auxiliary body 222 according to another embodiment.

5A to 5C, the movable assisting body (hereinafter referred to as the second movable assisting body 222b) according to the present exemplary embodiment may be formed to be used by being coupled to a moving means such as a bicycle. When the user wants to photograph the camera 230 while riding the vehicle, the main body 210 is mounted on the second movable auxiliary body 222b and the second movable auxiliary body 222b is coupled to the moving means. Can be used. Thus, the user can conveniently take a camera while moving using the camera module 200.

5A through 5B, the second movable auxiliary body 222b includes a frame 2223 and a vibration damping unit 2224 mounted to the frame 2223. The frame 2223 is generally formed in a cylindrical shape. The vibration damping unit 2224 is disposed in the inner space formed by the frame 2223. At least a part of the vibration damping unit 2224 is formed to correspond to the shape of the main body 210. As a result, the main body 210 may be inserted into and coupled to the vibration damping unit 2224.

On the other hand, the frame 2223 is preferably formed of a rigid material, the vibration damping portion 2224 is preferably formed of a material such as urethane with a slight stretch. Thus, even if the frame 2223 receives vibration from the moving means, due to the inertia of the vibration damping unit 2224 and the main body 210 coupled thereto, the shaking of the main body 210 can be minimized.

As described above, embodiments of the fixed auxiliary body 221 and the movable auxiliary body 222 have been described. When any one of these auxiliary bodies is mounted on the main body 210, the switching of the photographing mode of the camera 230 occurs. Hereinafter, a method of controlling a shooting mode switching according to the present invention will be described.

In the first embodiment, the identification information of the stationary auxiliary body 221 and the movable auxiliary body 222 are called first and second identification information, respectively, and the photographing modes corresponding to the first and second identification information are respectively referred to. And a second shooting mode.

According to the first embodiment, when at least one of the first and second identification information is detected by the wireless communication unit 240, it is determined whether the current photographing mode is a photographing mode corresponding to the detected identification information. If the current shooting mode is a shooting mode corresponding to the already detected identification information, switching of the shooting mode does not occur. For example, if the current photographing mode is already the first photographing mode and the first identification information is detected, the switching of the photographing mode does not occur.

However, if the current shooting mode is not the shooting mode corresponding to the detected identification information, switching of the shooting mode occurs. For example, when the current photographing mode is the second photographing mode and the first identification information is detected, the controller 250 switches the current photographing mode to the first photographing mode. Similarly, when the current photographing mode is the first photographing mode and the second identification information is detected, the controller 250 switches the current photographing mode to the second photographing mode. Hereinafter, specific examples of the first and second photographing modes will be described.

In the first embodiment, the first and second photographing modes are determined by two factors: frame per second and resolution. Frames per second means the number of images taken by the camera per second. In addition, the resolution is an index indicating the precision of the image photographed by the camera.

That is, the first and second photographing modes of the first embodiment are determined to be at least one of the first and second frames per second and at least one of the first and second resolutions. The first and second frames per second have different values, and the first and second resolutions have different values. For example, the first photographing mode may be a mode when the first frames per second and the first resolution are set, and the second photographing mode may mean a mode when the second frames per second and the second resolution are set.

In detail, when the photographing mode is switched, the controller 250 may adjust the driving speed of the shutter plate (not shown) of the camera 230 to change the first frame number to the second frame number or vice versa. In addition, the controller 250 may pixel bin the image sensor (not shown) of the camera 230 to change the first frame number to the second frame number or vice versa.

7A and 7B are conceptual views illustrating a photographing state of the camera 230 in the first and second photographing modes, respectively.

In detail, the first and second photographing modes are the photographing modes switched when the fixed assistant 221 and the movable assistant 222 are mounted. When the movable auxiliary body 222 is mounted, the probability of shooting a subject having a higher speed than when the fixed auxiliary body 221 is mounted increases. Therefore, the number of frames per second in the second shooting mode is preferably larger than the number of frames per second in the first shooting mode. On the other hand, as the number of frames increases, the image storage capacity increases. Therefore, as a compensation for this, it is preferable that the resolution of the second shooting mode is smaller than the resolution of the first shooting mode. Thus, even if the memory has a limited storage capacity, it is possible to obtain an image of optimized quality by taking pictures in different shooting modes according to the speed of the subject in the image.

In addition, the display unit 151 may display an image currently being captured and a separate shooting mode information window 310 together. The photographing mode information window 310 displays information regarding the photographing mode of the switched camera. Therefore, the user can easily check the information about the shooting mode of the camera 230.

Meanwhile, in the first embodiment, only the case where the number of frames per second and the resolution change together when switching the shooting mode is described, but only one of the two may be changed.

On the other hand, since the shooting mode can be determined by other factors besides the number of frames per second and the resolution, a second embodiment in which the shooting mode is determined by the zoom ratio will be described. The following description will focus on differences except for common parts of the second embodiment and the first embodiment.

8A and 8B are conceptual views illustrating photographing states of the camera 230 in the first and second photographing modes of the second embodiment.

In the second embodiment, the first and second photographing modes are determined by the zoom magnification. That is, the first and second capturing modes mean a case where the first zoom ratio and the second zoom ratio are set, respectively. In detail, when switching the shooting mode, the controller 250 may adjust the relative distance between the plurality of lenses in the zoom module of the camera 230 to change the first zoom factor to the second zoom factor or vice versa.

In addition, in the second embodiment, the identification information of the flight type auxiliary body which is formed to be able to fly and the auxiliary body which is not is called first and second identification information, respectively. In addition, the photographing modes corresponding to the first and second identification information are referred to as first and second photographing modes, respectively. For example, the flying auxiliary body may be an auxiliary body provided with a rotating body for the purpose of flying in the air. That is, the second movable assistant 222b illustrated in FIGS. 4A to 4C may also be one of the flying assistants.

On the other hand, when the flying aid is mounted on the main body 210, it is common to float the camera module 200 above the air, and to shoot while maintaining a certain distance from the subject. Therefore, in this case, it is preferable that the zoom magnification of the first photographing mode is smaller than that of the second photographing mode so that the subject can be photographed more efficiently by photographing at a lower zoom magnification.

Meanwhile, the display unit 151 may display the current photographing image and the separate photographing mode information window 320 together. The photographing mode information window 320 displays information regarding the photographing mode of the switched camera. In the present embodiment, the photographing mode information window 320 is displayed as 'narrow angle' or 'wide angle', but is not limited thereto. For example, a number indicating the zoom ratio may be displayed on the shooting mode information window 320. On the other hand, through the shooting mode information window 320, the user can easily check the information on the shooting mode of the switched camera 230.

Meanwhile, in the third embodiment, the first and second photographing modes are determined by whether at least one of the image stabilizer function and the movement path storage function is activated. For example, the first shooting mode refers to a case in which both the camera shake prevention function and the movement path storing function are activated in the camera 230, and the second shooting mode is both deactivated. It may mean that the condition is equipped.

In detail, when the image stabilizer function is activated, the controller 250 controls the camera 230 to shake the sensor or the lens of the camera 230 together with the vibration when a vibration caused by the shake is detected.

In addition, when the movement path storing function is activated, the controller 250 stores the photographing position information of the camera 230 by using the position information module of the wireless communication unit 240.

Further, in the third embodiment, identification information of the vehicle-mounted auxiliary body and the auxiliary body which is formed to be mountable to the moving means is called first and second identification information, respectively, and corresponds to the first and second identification information. The photographing modes to be referred to as first and second photographing modes, respectively. For example, the vehicle-mounted assistant may also be one of the vehicle-mounted assistants, as shown in FIGS. 5A-5C.

In the first shooting mode, both the camera shake prevention function and the movement path storing function of the camera 230 are activated. Thus, when the moving means-mounted auxiliary body is mounted on the moving means to take an image, the vibration transmitted from the moving means may be further reduced, and the moving path may be stored.

Meanwhile, the display unit 151 may display the current photographing image and the separate photographing mode information window 330 together. The photographing mode information window 330 displays information regarding a photographing mode of the switched camera. In the present exemplary embodiment, the image capture mode information window 330 may display 'the image stabilizer function ON' or the 'image stabilizer function OFF'.

In addition, when the movement path storage function is activated, a separate map window 340 may be displayed on the corner of the display unit 151. In addition, the movement path of the camera module may be displayed on the map window 340.

As described in the first to third embodiments, by applying a plurality of auxiliary bodies having various functions to the main body 210 so as to be replaced, it is possible to appropriately change the shooting mode of the camera 230 according to the situation. .

On the other hand, it is possible to control the start of camera shooting through the terminal body, which will be described.

In the present embodiment, when the wireless communication unit 240 of the main body 210 recognizes the identification information of the auxiliary body, the wireless communication unit 240 of the main body 210 communicates with the wireless communication unit 110 of the terminal body, the display unit At 151, a notification window 360 related to the start of recording is output. That is, if the controller 250 detects the state in which the auxiliary body 220 is mounted on the main body 210, the controller 250 does not immediately start recording, but starts recording once more to the user through the output notification window 360. You can start shooting after receiving confirmation. As a result, the user may control the shooting start time regardless of the time when the auxiliary body 220 and the main body 210 are mounted.

When the user touches the virtual button associated with the start of shooting, the camera 230 starts shooting. In this case, the image captured by the camera 230 is output through the display unit 151 of the terminal body.

In addition, the user may remotely adjust the photographing angle of the camera 230 of the main body 210 through the terminal body. Hereinafter, this will be described in detail.

11A to 11D are conceptual views illustrating changing the photographing angle of the camera 230 through manipulation of the virtual icon 350 output to the display unit 151.

Referring to FIGS. 10 and 11, when the virtual button related to the start of recording is touched in FIG. 10, the display unit 151 outputs the captured image of the camera 230 and at the same time the virtual icon 350 related to the changing the shooting angle. ) Can be output at the same time. Accordingly, the user may change the photographing angle of the camera 230 by touching the output virtual icon 350.

11A through 11D, the virtual icon 350 may include

arrow icons

351, 352, 353, and 354 which indicate lower, upper, left, and right directions.

In detail, when the arrow 351 indicating the downward direction is touched, the main body 210 may be rotated on the auxiliary body 220 in the D1 direction so as to capture the lower side than the current photographing view.

Similarly, when the arrow 352 indicating the upward direction is touched, the main body 210 may be rotated on the auxiliary body 220 in the D2 direction to capture the upper side than the current photographing view.

In addition, when the arrow 353 indicating the left direction is touched, the main body 210 may be rotated on the auxiliary body 220 in the D3 direction so as to photograph the left side than the current photographing view.

Finally, when the arrow 354 indicating the right direction is touched, the main body 210 may be rotated on the auxiliary body 220 in the D4 direction so as to photograph the left side of the current photographing view.

At this time, while the user's touch input is made, the main body 210 is continuously rotated on the auxiliary body 220, and the moment the user does not touch, the rotation is stopped. Therefore, the main body 210 may be rotated at various rotation angles on the auxiliary body 220.
