[0001] APPARATUS FOR GENERATING PANORAMA [0002] PHOTOGRAPH USING KEY PAD AND METHOD USING THE SAME [0003]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus and method for generating panoramic photographs using a keypad, and more particularly, to setting photographing regions of photographs constituting a panoramic photograph using keys of a keypad. In addition, the present invention relates to a method for accurately connecting and photographing photographs of respective photographing regions.

A conventional digital camera or a portable terminal device that provides a digital photographing function stores and displays image data generated by photographing a subject. Such portable terminal devices and the like have been developed to provide not only the above basic functions but also various functions such as editing of image data and panoramic photographing.

Here, a panoramic photograph is a photograph taken so as to be viewed at a glance, such as a landscape spreading laterally. This is because the field of view is so wide that the subject can not be captured at a time through the camera lens. As shown in FIG. 1, since the scenery 100 is too wide, the camera viewing angle 110 of the portable terminal device or the like can be captured only to a part of the scenery 100. FIG. In this case, if a subject such as a scenery is divided and photographed, a 360-degree omnidirectional view can be expressed by a single photograph.

However, when the panoramic photographing is performed in order to generate the panoramic photograph, various problems arise.

First, a conventional portable terminal device or the like manually adjusts a divided photographic region manually by the user. That is, a digital camera or a portable terminal device having such a function is fixed to a tripod or the like, and the viewing angle of the lens is constantly moved in one direction to the left or right. At this time, since the user moves the lens angle horizontally arbitrarily without a certain reference, the divided photographed images can be shot separately without being connected to each other. In addition, there is a problem that only the left and right directions can be secured between the divided pictures, and the connectivity in the left and right and up and down directions can not be ensured at the same time.

Next, there is a problem in that the sizes of overlapping regions between adjacent divided pictures are not constant. When connecting divided pictures, they are connected on a personal computer using overlapping areas between adjacent divided pictures. If such overlapping areas are too wide, the connection part of the divided pictures may become unnatural. This is because the overlap areas appear differently on the photographed photographs. That is, due to the difference in brightness between the divided pictures, there is an inconvenience that the personal computer needs to be modified and edited through various applications such as Photoshop CS.

In order to solve the above problems, an object of the present invention is to provide an apparatus for generating a panoramic picture using a keypad.

Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the accompanying drawings.

1 is an exemplary view for explaining a viewing angle of a lens using a conventional photographic apparatus. 1, an apparatus 200 for generating a panoramic image using a keypad according to the present invention includes a keypad 210, a photographing unit 220, a storage unit 230, a display unit 240, a panoramic photographing unit 250, And a control unit 260.

The panoramic photographing apparatus 200 is an apparatus for generating a panoramic photograph, and sets an area to be divided photographed in advance using the keypad 210. Then, each of the divided photographed photographs is superimposed with a predetermined size so that it can be photographed. Here, it is assumed that the position of each divided photographic region corresponds to each key of a predetermined key region on the keypad 210. [ Referring to FIG. 3, it can be understood schematically that the shooting regions 120-1 to 120-6 of the divided pictures of scenery 100 are set in the present invention.

Hereinafter, each configuration of the panoramic photographing apparatus 200 and its operation will be described in detail.

The keypad 210 is a numeric keypad attached to a mobile communication terminal, PDA, or the like. Such a keypad may be separately connected via a USB or the like. The keypad 210 is exemplified in the present invention but may include a form such as a small keyboard attached to a PDA or the like. In addition, a keypad or a keyboard shape displayed on a screen in a mobile communication terminal configured with a full screen . In this way, all means for easily setting the shooting area of the divided photographs will be possible. However, the keypad 210 of the present invention is well suited for setting the photographing area of the divided photograph because the photographing area of the divided photograph and each key on the keypad can be visually matched. Referring to FIG. 4, an operation of setting a shooting region of a divided picture will be described as follows.

As shown in FIG. 4, the panoramic photographing apparatus 200 includes a keypad 210 and a display unit 240. 1 ',' 2 ',' 3 ',' 4 ',' 5 ', and' 6 'keys on the keypad 210 can be set as the shooting area 210-1 of each divided picture. At this time, the photographing area 210-1 of each divided photograph may be set by directly pressing the respective keys '1' to '6' in the specific mode such as the panoramic photographing mode. Then, it can be understood that the subject 120 photographs the photographing regions 120-1 to 120-6 of the divided photographs corresponding to the respective positions of the keys '1' to '6' on the keypad. That is, each key of the setting area 210-1 on the keypad corresponds one-to-one to the photographing areas 120-1 to 120-6 of the divided photographs.

Next, the photographing unit 200 photographs a subject through a camera lens. Of course, the photographing unit 200 is configured to be capable of photographing according to the photographing mode of the panoramic photograph. When shooting each divided picture in the photographing mode of the panoramic picture, the photographing unit 200 displays a tag or the like as to which of the previously set photographing regions 120-1 to 120-6 the corresponding divided picture corresponds to . In other words, in order to generate a panoramic picture, each divided picture needs to be connected, so it is necessary to distinguish which shooting region the respective divided pictures were shot in.

It is preferable that the photographing unit 200 is controlled so as to photograph each divided photograph in a predetermined order. Of course, the operation of changing the lens direction of the photographing unit 200 and looking at the respective photographing regions 120-1 to 120-6 is manually performed by the user. However, the photographing sequence of each of the photographing regions 120-1 to 120-6 may be set in advance, and each of the corresponding keys may emit light sequentially, thereby informing the user of the order in which the divided photograph is to be photographed.

This predetermined order is necessary for connecting the respective divided photographs when the panoramic photograph is generated thereafter. Here, it is preferable that the predetermined order is such that the divided photograph of the next sequence of the previously taken divided photograph is a divided photograph of any one of the photographing regions, which is in connection with the photographing region of the previously captured divided photograph. In other words, the photographing sequences of the adjacent photographing regions are also continued. At this time, the predetermined order may be various numbers of course. As another example, even if the shooting sequence does not necessarily follow the shooting regions that are connected in this manner, if there is a split shot that is photographed in the shooting region to be connected, it is enough to allow the shot shot to be taken at any time in the shooting region.

The predetermined order may be set in advance by pressing the respective keys in order by the user, but it is also possible to automatically set the order according to the above condition through the control unit 260 of the present invention.

When the user manually sets the order, one of the divided photographs is taken and then the corresponding key of the next photographable photographing area is emitted, and when the order is automatically set, the corresponding key of the next photographing area can be configured to emit light will be.

On the other hand, the storage unit 230 stores the divided pictures taken by the photographing unit 200 for generating a panoramic picture. The storage unit 230 stores panoramic photographs generated by connecting the divided photographs. Various control programs for generating the panoramic photograph according to the present invention will also be stored.

Then, the display unit 240 displays a preview image of each divided photograph to be photographed. Of course, you will also be able to display the resulting panorama picture. Here, when a preview image of each divided photograph is displayed, predetermined portions of the divided divided photographs are also superimposed and displayed. This predetermined portion can be displayed transparently. The reason why the predetermined portion is superimposed and displayed in a transparent manner is to secure the connectivity between the divided pictures by allowing the preview image to be photographed to overlap when the predetermined portion overlaps. An example in which a divided picture is taken with reference to the divided picture photographed by reference to FIG. 5 will be described. 5, it is assumed that a preview image of the shooting region 120-1 of the divided photographed still image and the next shooting region 120-2 in the predetermined order is displayed. At this time, predetermined portions on the right side of the photographed photographing region 120-1 are superimposed on the preview image of the photographing region 120-2 to be photographed, and are provided transparently. Then, it is possible to photograph the divided picture by adjusting the angle of the lens so that the upper preview image is matched with the predetermined part provided transparently.

The above operation will be described in more detail with reference to FIG. 6, the photographing areas 120-1 to 120-6 of the divided photographs are divided into the photographing area 1 (120-1), the photographing area 2 (120-2), the photographing area 3 (120-3) 4 (120-4), the shooting region 5 (120-5), and the shooting region 120-6. In the present embodiment, the photographing region 1 120-1, the photographing region 2 120-2, the photographing region 3 120-3, the photographing region 4 120-4, the photographing region 5 120-5, It is assumed that a divided picture is taken in the order of the area 6 (120-6). In this case, after the shooting region 1 (120-1) is photographed, a predetermined portion of the right side of the shooting region 1 (120-1) is displayed in the preview image of the shooting region 2 (120-2) ), The connection of the image is ensured by referring to this. That is, the predetermined portion on the right side of the photographing region 1 (120-1) is referred to. At the time of photographing of the photographing region 3 (120-3), the predetermined portion on the right side of the photographing region 2 (120-2) is referred to. Similarly, at the time of photographing of the photographing area 4 (120-4), a predetermined lower part of the photographing area 1 (120-1) is referred to, and at the time of photographing of the photographing area 5 The lower predetermined portion and the predetermined portion on the right side of the photographing region 4 (120-4). The shooting region 6 (120-6) is also photographed in the same manner. In this way, not only the connectivity between the divided pictures can be ensured but also the connectivity between the left and right directional divided pictures as well as the connectivity between the upper and lower directional divided pictures can be secured. Here, the predetermined portion may be set to have a size and an area in advance, and may be configured to be set based on the pixel, the length (inch) of the overlapping portion, and the like. Then, when the user manually adjusts the direction of the lens angle, the size of the overlapping region can be adjusted to be uniform. In addition, since the size of the overlapping region is not widened, it is possible to prevent the contrast difference of each divided image from becoming large, and it is possible to reduce the correction work when creating the panoramic image.

Next, the panoramic image generation unit 250 generates one panoramic image by connecting each of the divided images photographed by the photographing unit 220 corresponding to the positions of the corresponding photographing regions. As described above, since the divided photographs are taken with reference to the divided photographs taken in conjunction with each other, they can be connected using the overlapping predetermined portions. Conventionally, each divided photograph is taken and connected and modified on a personal computer. However, in the panoramic photographing apparatus of the present invention, it is possible to directly create a panoramic photograph by connecting it. This is possible because the size and area of the predetermined portion are predetermined and the position of each divided picture is fixed. On the other hand, the panoramic image generation unit 250 can reduce the generated panoramic image. Panoramic pictures can only be a single piece of very large size picture that is linked to the split picture. Therefore, the display unit 240 can not display the whole picture by using the scroll function. Therefore, it can be configured so that it is reduced to a constant magnification so as to provide an entire picture on the display unit 240. [

Finally, the control unit 260 controls a series of operations of the panoramic photographing apparatus 200 according to the present invention. That is, it controls the operation of each of the above-described configurations. In addition to the normal control operation described above, the control unit 260 may also be configured to provide determination of whether or not the images are overlapped in the overlapping areas, notification, automatic photographing function, and the like.

Hereinafter, the determination of the stitch alignment and the automatic photographing function will be described.

First, whether or not a predetermined portion of the divided photographed still image and the corresponding portion of the preview image are matched in the overlapping region or overlapping region described above is directly determined by the user while adjusting the direction of the lens angle. This is possible because a predetermined portion of the divided picture is provided transparently. However, it may be difficult for the user to accurately determine whether or not the matching is done by the naked eye, and it may be difficult to accurately capture the matching moments.

The control unit 260 may also be configured to directly control the matching and the automatic photographing function. The criterion of judgment may be whether or not the predetermined portion and the color of the corresponding portion coincide with each other. That is, it may be configured to extract the colors of the divided pictures in the overlapping area and to judge based on whether or not they match each other. The color classification or shape may be an additional judgment criterion by the extraction of such colors.

The control unit 260 may be configured to display a notification of matching to the display unit 240 at the time of matching after determining the matching. It may be configured so that the user can easily recognize by displaying a special symbol or changing the color of the entire screen. In addition, although not shown in the drawing, a notification sound may be output through a configuration such as a speaker.

If the user has a notification of matching or not, the user can directly shoot the divided picture by pressing the shutter. In addition, the controller 260 can be configured such that the shutter is automatically pushed at such a matching time so that the divided picture is photographed. That is, when the user slightly adjusts the direction of the lens angle while watching the preview image of the display unit 240, the user is notified of matching at the moment of matching, and the user directly shoots the image by pressing the shutter or is automatically photographed.

On the other hand, when the user directly presses the shutter to shoot, it can be configured to shoot by pressing a key corresponding to the shooting area as already mentioned above. The pressing operation of the key will be described with reference to Fig. 7 (a), the user presses the '1' key using the finger 300 of the user. When the '1' key is depressed, a preview image of the shooting region 120-1 corresponding to the '1' key is displayed on the display unit 240. As shown in FIG. 7 (b), when the finger 300 of the user is released from the '1' key, the photographing is started.

As shown in FIG. 7 (a), the user can accurately recognize the photographing area by adjusting the direction of the lens angle while viewing the preview image while the key is depressed.

The panoramic photographing apparatus 200 may be applied to a portable terminal having a keypad such as a mobile communication terminal, a digital camera, and a PDA (Personal Digital Assistants). Even if the portable terminal device does not have a keypad, the functions of the present invention can be implemented through USB or the like as described above.

Next, a method of generating a panoramic picture using the keypad according to the present invention will be described. 8 is a flowchart of a method of generating a panoramic picture using a keypad according to the present invention.

Referring to FIG. 8, a method of generating a panoramic picture using a keypad according to the present invention includes steps of setting a shooting area of a divided picture using a keypad (S100), displaying a preview image of any one shooting area S200 A step S400 of displaying a preview image of a next shooting region according to a predetermined order and displaying a predetermined portion of the taken shooting region in a transparent manner, A step S500 of photographing and storing a predetermined portion and a corresponding portion of the preview image so as to match each other, a step S600 of confirming whether all the divided photographs of the photographing region have been photographed (S600), setting the panoramic photograph by connecting the photographed divided photographs A step S700, and a step S800 of displaying the generated panoramic photograph. Each step is described as follows.

First, the user first sets each photographing area for creating a panoramic photograph using the keypad (S100). In this case, the user must enter the panoramic photographing mode during the photographing mode. In the panorama photographing mode, the photographing area of each of the divided photographs constituting the panoramic photograph is set, and is set to correspond to each key on the keypad 210. The user can arbitrarily be configured to select and set the required number and area key. For example, the user can set the desired shooting regions 120-1 to 120-6 with the keys '1', '2', '3', '4', '5' .

When a key corresponding to one of the shooting regions is pressed, a preview image of the shooting region corresponding to the key is displayed on the display unit 240. (S200) For example, in the shooting region 1 (120-1 The preview image of the photographing area 120-1 is displayed on the display unit 240 while the " 1 " When the finger 300 is released from the '1' key, the photographing unit 220 photographs a divided photograph of the currently captured preview image, and the divided photographs photographed in the storage unit 230 are stored (S300)

Then, a preview image of the next photographing area of the previously captured photographing area is displayed, and a predetermined portion of the currently photographed photograph, which is concatenated with the current preview image, is superimposed and displayed in a transparent manner (S400). Here, If the shooting order is determined in advance, it may be configured to emit a key on the keypad 210 according to a predetermined sequence and to guide the user to the order. Of course, if the predetermined order is not set in advance, the user can arbitrarily set the next order at the time of shooting. However, if there is no photographing area previously photographed in the photographing area connected to the area to be photographed, the next photographing sequence may be derived by an operation such as not showing the current preview image on the display unit 240 or the like.

On the other hand, when the predetermined portion displayed in the upper part and the corresponding portion of the current preview image are matched, the user starts shooting, and the divided pictures photographed in the storage unit 230 are stored (S500). On the other hand, ) Can be configured to determine whether the matching is on the basis of color or the like and notify the user or to automatically start shooting. Here, as a method of informing the user of the matching, the display may be configured to display a notification indicating matching on the display unit 240 or audibly notify via a speaker or the like not shown.

On the other hand, the controller 260 determines whether all of the divided photographs of the previously set shooting regions 120-1 to 120-6 have been photographed and stored (S600). If not yet photographed, the controller 260 proceeds to step S400 And then displays the current preview image, captures it, and stores it repeatedly.

At this time, when the controller 260 determines that all the photographic areas 120-1 to 120-6 have been photographed and stored, the panoramic image generation unit 250 connects all of the divided photographs stored in the storage unit 230, (S700). Here, each of the divided photographs is connected to each other at a position corresponding to the corresponding photographing area, and is generated as one panoramic photograph.

On the other hand, the generated panoramic image is very large because six panoramic images are connected and become a single photograph. Therefore, the entire panoramic picture can not be displayed on the display unit 240. Therefore, the control unit 260 can display the panoramic image using the scroll function. (S800) On the other hand, the panoramic image generation unit 250 can reduce the panoramic image to fit the screen size of the display unit 240 . ≪ / RTI > Of course, the generated panorama photograph is stored in the storage unit 230. [ Thus, the panoramic photographing apparatus 200 of the present invention can directly create panoramic photographs by connecting divided photographs without using a personal computer.
