In this specification, the terms " comprising ", or " comprising ", etc. should not be construed as necessarily including the various elements or steps described in the specification, Or may be further comprised of additional components or steps. Also, the terms " part, " " module, " and the like described in the specification mean units for processing at least one function or operation, which may be implemented in hardware or software or a combination of hardware and software .

The present invention relates to a photographing device, for example, a digital camera, and proposes a photographing device for automatically focusing an object using light (for example, a laser) and visually displaying a photographable range (frame) .

With the recent miniaturization of a digital camera, it is becoming difficult to mount a display such as a monitor or a touch panel. Accordingly, there is a demand for an imaging device that can easily and visually specify a photographable range without displaying in accordance with such miniaturization.

The present invention visually displays the photographable range using a laser, so that photographing is possible even without a display.

In addition, since the user can visually check the photographable range, it is possible to know the composition of the photograph to be photographed even without looking at the lens window of the photographing apparatus, thereby realizing the photographing of the desired composition.

Hereinafter, various embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, for convenience of explanation, it is assumed that the photographing apparatus is a camera. However, the photographing apparatus is not limited to a camera as long as photographing can be performed, and includes a camcorder and the like.

FIG. 1 is a view showing a photographing method using a camera according to an embodiment of the present invention, and FIG. 2 is a view showing a maximum photographable range according to an embodiment of the present invention. FIG. 3 is a view showing adjustment of a photographable range according to an embodiment of the present invention, and FIG. 4 is a view showing adjustment of a photographable range according to another embodiment of the present invention.

Referring to FIG. 1, the photographing apparatus (for example, camera 100) of the present embodiment includes a main body 110 and a lens 112, and displays a focusing pointer in a subject unlike an existing camera, The photographable range can be visually displayed on the basis of the reference.

According to one embodiment, the camera 100 uses the first laser to automatically focus the subject. Specifically, when the user sets the camera 100 to the subject such that the first laser is irradiated on the subject, the camera 100 can perform auto focusing on the subject.

For example, the camera 100 irradiates the first laser with the subject using a first optical device, for example, a first laser generator, and then measures the reflected light reflected from the subject, Distance can be measured.

Of course, the camera 100 can calculate the distance to the subject only when the first laser is irradiated with the subject for a predetermined time or more. This is because unnecessary load may be applied to the camera 100 if the distance to the subject is continuously calculated without time limitation.

Then, the camera 100 can visually display the focusing pointer 200 in the direction of the subject in accordance with the calculated distance. As a result, the user can visually confirm that the camera 100 is focused on the subject. Here, the focusing pointer 200 is not limited to a particular shape, size, and color, and may have various shapes, sizes, and colors as long as it is visually well visible to a user.

On the other hand, since the user holding the camera 100 can move during the focusing process, it may be difficult to determine an accurate focusing point. Therefore, in order to determine an accurate focusing point, the camera 100 performs distance correction in calculating the distance in consideration of the user's motion and performs position correction at the time of position determination. Therefore, even if the user moves to some extent, the focusing function can be easily achieved to the specific position by the above correction function.

Subsequently, the photographable range 122 after the auto-focusing is visually displayed. Here, the photographable range 122 may correspond to a frame of a photograph obtained after photographing.

According to one embodiment, the camera 100 can visually display the photographable range 122 outside the camera 100 using at least one second laser. Here, there are various photographable ranges 122, and such photographable range 122 can be determined according to a user's input (command).

However, in the photographable range 122, the minimum photographable range 122a and the maximum photographable range 122c may be basically set. In this case, there is a continuous photographable range 122b between the minimum photographable range 122a and the maximum photographable range 122c.

According to one embodiment, the photographable range 122 may have a square or rectangular shape with respect to the focusing pointer 120. Actually, when the camera 100 irradiates the second lasers in four directions, and the second lasers connect the irradiated points with imaginary lines, a photographable range 122 of a square or rectangular shape can be formed have. Of course, the photographable range 122 is not limited to a rectangular shape, and may have various shapes.

On the other hand, the photographable range 122 can be adjusted by operating a physical structure or a software entity such as a button of the camera 100 or the like. That is, the photographable range 122 can be adjusted according to a user's input (command).

According to another embodiment, the photographable range 122 may be automatically adjusted. For example, when the user pulls the camera 100 toward his / her body after focusing, the lens 112 is zoomed in. When the user is pushed in the opposite direction, the lens 112 can be zoomed out. For this operation, a motion sensor may be installed in the camera 100. [

As another example, if the user rotates the camera 100 to the right after focusing, the lens 112 is zoomed in, and if rotated to the left, the lens 112 can zoom out. For this operation, a gyro sensor may be installed in the camera 100. [

That is, the photographable range 122 may be manually adjusted according to a user's input, or may be automatically adjusted according to the movement of the camera 100. [ However, the adjustment method is not particularly limited and may be variously modified.

Hereinafter, the subject focusing and the photographable range adjustment process will be described in detail, for example.

Referring to FIG. 2, when the camera 100 irradiates the subject 200 with the first laser, automatic focusing to the subject 200 can be performed. Here, the automatic focusing may be performed through distance measurement as described above. Of course, the automatic focusing method is not limited as long as automatic focusing can be performed.

Then, the camera 100 can output the four second lasers, for example, in

predetermined directions

200a, 200b, 200c and 200d to set the maximum photographable range 122c. Here, the tilting angle of the laser generators outputting the second lasers and the intensity of the second laser may be set in advance so as to form the maximum photographable range 122c after focusing.

Also, the focusing pointer 120 may be located at the center of the maximum photographable range 122c such that the subject 200 is positioned near the center of the maximum photographable range 122c. Of course, this does not mean that the focusing pointer 120 is positioned at the center of the subject 200, and the focusing pointer 120 does not have a position limitation for aiming the subject 200.

According to one embodiment, the maximum photographable range 122c after the automatic focusing can be immediately formed.

According to another embodiment, the maximum photographable range 122c may be formed by being gradually enlarged from the small photographable range 122. [ In this case, the laser generators outputting the second lasers can be tilted in accordance with the photograpable range 122 in which they are enlarged.

By forming such focusing and maximum photographable range 122c, the user can recognize the relative size of the subject 200 within the maximum photographable range 122c and the maximum photographable range 122c.

When the user recognizes that the size of the subject 200 is small in the overall composition and wants to set the size of the subject 200 to be large in the entire composition, the user will operate the zoom-in function as shown in FIG.

According to one embodiment, a user can perform a zoom-in function by operating a physical or software operation object (e.g., a button) formed on the camera 100. [

For example, when the user continuously presses a certain button, the photographable range 122 can be sequentially reduced from the maximum photographable range 122c, and when the user releases the pressing force of the button, May be fixedly formed.

At this time, the laser generators can output the second lasers in the inward direction of the maximum photographable range 122c so that the photographable range 122 is reduced. For this operation, the laser generators must be able to tilt or move. A detailed description thereof will be described later.

As another example, when the user moves the specific lever from right to left, the photographable range 122 can be sequentially reduced from the maximum photographable range 122c, and when the user stops the movement of the lever, the photographable range 122n May be fixedly formed.

In this case, the user can visually recognize reduction of the photographable range 122 and recognize the composition and size of the subject 200 in the photographable range 122, so that the subject 200 can recognize a desired composition or size If it is judged to have the photographing range 122, the photographing range 122 will be fixed. At this time, the laser generators will be illuminating the second lasers at

predetermined points

300a, 300b, 300c and 300d.

Referring to another embodiment with reference to FIG. 4, the camera 100 may form a minimum photographable range 122a after auto-focusing.

Then, in accordance with the user's command, the photographable range 122a is enlarged to realize the desired photographable range 122k.

In summary, the camera 100 of the present embodiment automatically forms the maximum photographable range 122c or the minimum photographable range 122a after performing the automatic focusing using the first laser, and then, Accordingly, the photographable range 122 can be reduced / enlarged to set a desired photographable range.

However, such a photographable range 122 can be clearly recognized by the user when a wall or the like is located behind the subject 200, such as in a room. However, in a place where the back of the subject 200 is popped, There is also a possibility that it is not possible to clearly recognize the possible range 122.

Therefore, in a space such as an outdoors, the laser generators can output lasers discontinuously instead of continuously outputting lasers. When the lasers are output discontinuously, the photographable range 122 due to human visual characteristics can be imaged far more effectively.

Whether to output the laser continuously or discontinuously may be manually performed according to a user's instruction, or may be automatically performed according to the determination of the sensor by mounting the sensor on the camera 100. [

2 and 3, the focusing pointer 120 is continuously displayed at the time of displaying the photographable range 122. However, the focusing pointer 120 may not be displayed after the maximum photographable range 122c is formed have. Even if the focusing pointer 120 is not displayed, the user is already aware that the subject 200 is focused on the subject 200 and the subject 200 is clearly visible in the photographable range 122c.

Although the above description refers to enlargement / reduction of the photographable range 122, the user may want to adjust the position of the subject 200. [ For example, if the subject 200 desires to be positioned on the right side of the composition, not on the center, the user can move the focusing pointer 120 to the left, in which case the photographable range 122 automatically moves to the focusing pointer 120).

Accordingly, the user can adjust the focusing pointer 120 and the photographable range 122 to realize a desired composition and a relative size of the subject 200. [

In addition, various modes are set in the camera 100 such as a portrait mode and a portrait mode. Depending on the mode, the shape or color of the focusing pointer 120, the size of the photographable range 122, . This function allows the optimum shooting to be performed according to the mode, and also allows the user to recognize which mode he or she has selected.

Of course, the selection of the mode may be performed by the user through the operation of the camera 100, but may be performed automatically according to the movement of the user. Whether the mode is selected in any way, the focusing pointer 120 or the photographable range 122 can be varied according to the selected mode.

Hereinafter, the physical structure of the camera 100 capable of setting auto focusing and photographable range will be described in detail with reference to the accompanying drawings.

5 (A), the camera 100 may include a main body 100 and a lens 112 to be zoomed in / out.

According to one embodiment, first optical devices, e.g., a first laser generator 502 for generating a first light (a first laser) for automatic focusing, and second light sources

Second laser generators

510, 512, 514, and 516 may be formed on the front side of the body 110 or on the front side of the lens 112. For example, . It is preferable that the

laser generators

502, 510, 512, 514 and 516 are formed on the front side of the main body 110 rather than the lens 112 to be zoomed in / out.

The

laser generators

502, 510, 512, 514 and 516 may be disposed outside the lens region 500.

The first laser generator 502 may be located between the

second laser generators

510 and 516. On the other hand, although not shown, a light receiving portion capable of receiving reflected light of the first laser reflected by the subject may further be formed on the front surface side of the main body 110. [ This is to measure the distance between the camera 100 and the subject.

The second laser generators 502 may be arranged in a rectangular shape to form a rectangular photographable range as shown in FIG. 5 (B).

In particular, for enlargement / reduction of the photographable range, the second laser generators 502 may have a tilting structure. That is, the second laser generators 502 can be tilted in accordance with the photographable range while being fixed to the main body 110.

In summary, the laser generators of this embodiment are installed directly on the camera 100 and can have a tilting structure.

In the above description, the photographable range of the rectangle is taken as an example, but the photographable range may be set in another form, and the arrangement and tilting structure of the laser generators may be varied according to the photographable range.

Referring to FIG. 6, a first laser generator 600 for autofocusing may be located between the

second laser generators

602 and 608 in the body or lens.

The

second laser generators

602, 604, 606, and 608 are arranged in a rectangular shape and may be configured to be movable on the corresponding

guides

610, 612, 614, or 616.

Specifically, the

second laser generators

602, 604, 606, and 608 move in the center direction along the

guides

610, 612, 614, and 616 when reducing the photographable range, 612, 614, and 616, the

guide

610, 612, 614, and 616 can be moved in the outward direction.

That is, enlargement / reduction of the photographable range can be realized by moving the

second laser generators

602, 604, 606 and 608 along the

guides

610, 612, 614 and 616.

Of course, the

second laser generators

602, 604, 606, and 608 may have additional structures that can be tilted for correct shooting range setting. In this case, the

second laser generators

602, 604, 606 and 608 may be automatically tilted moving along the

guides

610, 612, 614 and 616 to form the desired coverage.

7A and 7B, the structure 700 in which the first laser generator 720 and the

second laser generators

722, 724, 726, and 728 are formed on the body 710 is referred to as a lens 112). &Lt; / RTI >

In other words,

laser generators

720, 722, 724, 726 and 728 are formed in separate structures 700 in this embodiment, unlike other embodiments where laser generators are formed directly in camera 100, The structure may be coupled to the camera 100. As the joining method, various joining methods such as a method in which a part of the structure 710 is attached to the lens 112 can be used.

Referring to FIG. 8, unlike the previous embodiments, the camera of this embodiment may implement a plurality of focusing pointers, preferably two focusing

pointers

800 and 802.

The plurality of focusing pointers are necessary for the user to compose based on a plurality of subjects. For example, if you make the center point of the subjects be the center of the picture, multiple subjects can be the center of the composition. This can be done by forming two focusing

pointers

800 and 802 corresponding to the subjects. In this case, the subjects are arranged on the left and right sides with respect to the center in the photograph.

A method of forming a photographic composition using a plurality of focusing pointers is a method in which a specific subject is emphasized less than a photographed image based on the subject using a single focusing pointer, You can be more prominent.

According to one embodiment, a camera may illuminate a first laser with a first subject to form a first focusing pointer, and then irradiate the first laser with a second subject to form a second focusing pointer. Here, the focusing pointer may be formed manually when a user command such as a specific button click is input after the first laser is irradiated to the subject, or when the first laser is continuously irradiated to the subject for a predetermined time or more It may be done automatically.

According to another embodiment, when the first laser alternately irradiates the first subject and the second subject for a preset time or times, the focusing

pointers

800 and 802 may be automatically formed with the subjects .

After forming these focusing pointers, a maximum photographable range or a minimum photographable range 804 can be formed.

In summary, the photographing method using the camera of this embodiment can form a photographable range after forming a plurality of focusing pointers.

In the above description, only two focusing pointers are exemplified, but three or more focusing pointers may be formed.
