Abstract:
Provided is a three-dimensional moving picture photographing apparatus for photographing a three-dimensional moving picture having a large depth, the apparatus including a horizontal track having a forward/rearward moving track and a leftward/rightward moving track, which are perpendicular to each other, a movable body moved along the horizontal track in forward/rearward and leftward/rightward directions, a horizontal rotary bar having one end connected to the movable body via a rotary shaft, and a camera installation section installed at the other end of the horizontal rotary bar, wherein a front portion of the camera installation section is normally directed in a photographing direction of a front surface even when the horizontal rotary bar is rotated. 
     As a single camera image sensor is used, the three-dimensional moving picture that can be seen without using equipment such as three-dimensional glasses with no optical loss can be photographed. In addition, since the moving picture photographed using the present invention has no problem such as flickering or afterimage and can be seen without using three-dimensional glasses, a person who has only one eye can also see the three-dimensional moving picture. In addition, since the images are photographed while moving in leftward/rightward and forward/rearward directions, the three-dimensional moving picture, which is comfortable, natural and has a large depth, like being seen with the naked eye, can be photographed.

Description:
TECHNICAL FIELD 
       [0001]    The present invention relates to a three-dimensional moving picture photographing apparatus and camera that are capable of recognizing a three-dimensional moving picture with the naked eye by continuously photographing moving pictures while moving a camera in forward/rearward and leftward/rightward directions, and more particularly, to a three-dimensional moving picture photographing apparatus and camera that are capable of photographing a three-dimensional moving picture having a large depth by continuously photographing moving pictures while moving the camera in leftward/rightward directions as well as forward/rearward directions. 
       BACKGROUND ART 
       [0002]    A three-dimensional image technology is in the spotlight as a next-generation image technology for implementing a vivid image. In recent times, various 3D image contents such as movies, education, advertisement, and so on, have been widely manufactured, and a scale of the related market is expected to be widely enlarged due to the distribution of 3D TV. 
         [0003]    A technology of photographing a three-dimensional moving picture uses a theory of binocular disparity in which a human sees an object through his/her two eyes. The two eyes are spaced about 65 mm from each other, the left eye and the right eye recognize different two-dimensional images, and finally, the brain superimposes the different two images to provide a three-dimensional feeling. Accordingly, in order to obtain a three-dimensional image, in general, a subject is photographed using two image cameras, which correspond to the left and right eyes, and a left image and a right image are synchronized and superimposed. 
         [0004]    When the two image cameras are used as described above, preparing for the photographing is largely time consuming because focuses and main visual angles of the cameras cannot be easily controlled, and making an image is also largely time consuming because a process of combining two images to make a three-dimensional image is very complex. In addition, since optical characteristics of the lens such as spherical aberration, chromatic aberration, and so on, are differently expressed at each lens of the cameras while being minimal, many effects are needed to correct the characteristics. 
         [0005]    In order to solve the problems, a technology in which light entering different lenses in different directions are photographed using a half mirror in a crossing manner to obtain the same effect as being photographed by two cameras (Korean Unexamined Patent Application, First Publication No. 2000-24767) has been developed, even in this case, a problem occurs due to a difference in characteristics of the two lenses, and optical loss is increased due to use of the half mirror. 
         [0006]    As described above, the three-dimensional moving picture photographing apparatus of the related art using the theory of the binocular disparity commonly has a disadvantage in which a depth in a three-dimensional image is small because images spaced apart leftward and rightward from each other are combined. While a technology in which a subject is disposed at a center and photographed by a plurality of cameras in various directions to increase a depth in a three-dimensional image (Korean Patent Registration No. 10-0324392) has been developed, this is a technology for photographing a stopped three-dimensional image, and a technology for photographing a moving three-dimensional moving picture is still within the technology using the binocular disparity. 
         [0007]    While the applicant has filed the invention related to a three-dimensional image photographing apparatus capable of photographing an image while reciprocating a single camera or a lens leftward/rightward and causing the brain to recognize a three-dimensional moving picture without three-dimensional glasses using afterimages of several tens of images per second with no degradation of the image due to the optical loss (Korean Unexamined Patent Application, First Publication No. 2011-0009740), the image photographed while moving leftward/rightward could not provide a large depth in the three-dimensional moving picture.

     DESCRIPTION OF EMBODIMENTS 
       [0032]    Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. 
         [0033]      FIG. 1  is a schematic view showing a structure of a three-dimensional moving picture photographing apparatus according to a first embodiment of the present invention. 
         [0034]    The three-dimensional moving picture photographing apparatus of the embodiment includes a horizontal track constituted by a forward/rearward moving track  110  and a leftward/rightward moving track  120 , a movable body  130 , a horizontal rotary bar  140 , and a camera installation section  150 . 
         [0035]    The horizontal track includes the forward/rearward moving track  110  and the leftward/rightward moving track  120 , which are linearly formed, disposed to cross each other, and the movable body  130  is moved forward/rearward and leftward/rightward by the forward/rearward moving track  110  and the leftward/rightward moving track  120 . 
         [0036]    In the embodiment, the leftward/rightward moving track  120  is configured to move forward and rearward along the forward/rearward moving track  110 , and the movable body  130  is configured to move along the leftward/rightward moving track  120 . Forward/rearward movement of the leftward/rightward moving track  120  and leftward/rightward movement of the movable body  130  are combined such that the movable body  130  is moved forward/rearward and leftward/rightward as a whole. 
         [0037]    However, the present invention is not limited to the structure of the embodiment, but a configuration falls into the scope of the present invention as long as a movable body can move forward/rearward and leftward/rightward by two tracks perpendicular to each other. 
         [0038]    One end of the horizontal rotary bar  140  is connected to the movable body  130  via a rotary shaft  141  to be rotated on a plane, and the camera installation section  150  is connected to an opposite end thereof. Accordingly, when the horizontal rotary bar  140  is rotated about the rotary shaft  141 , the camera installed at an opposite side of the camera installation section  150  is moved in a circular shape. The camera installation section  150  is a section at which the camera configured to photograph a moving picture can be installed, and moves in a circular shape by rotation of the horizontal rotary bar  140 . In particular, the camera installation section  150  of the embodiment is connected to the horizontal rotary bar  140  via a rotary shaft  142 , and rotated in an opposite direction of the horizontal rotary bar  140  about the rotary shaft  142  according to rotation of the horizontal rotary bar  140 , and the camera installation section  150  is always directed to a front side thereof. 
         [0039]    In addition, rotation of the camera installation section  150  is adjusted such that a lens of the camera installed at the camera installation section  150  is continuously directed to one point of a preset front side. Specifically, the forward/rearward moving track  110  is adjusted to be directed rightward with reference to when the installation section  150  is disposed at a left side of the forward/rearward moving track  110 , and the forward/rearward moving track  110  is adjusted to be directed leftward with reference to when the camera installation section  150  is disposed at a right side of the forward/rearward moving track  110 , such that the lens of the camera is directed to one point of the front side. 
         [0040]    The structure in which the camera installation section  150  is operated to be directed to one point of the front side and the structure in which the camera is installed at the camera installation section  150  are not particularly limited, and all structures to which one of ordinary skill in the art can apply are possible. 
         [0041]    In addition, the camera installed at the three-dimensional moving picture photographing apparatus of the embodiment is not particularly limited as long as the camera can photograph moving pictures recognized as a moving picture due to an afterimage in the brain by photographing several to several hundreds of frames per second. 
         [0042]    Hereinafter, an operation of the three-dimensional moving picture photographing apparatus according to the embodiment will be described. 
         [0043]      FIG. 2  is a schematic view showing an operation of the apparatus according to the first embodiment of the present invention. 
         [0044]    In the operation shown in  FIG. 2 , since the horizontal rotary bar  140  is rotated in a clockwise direction by one rotation while the movable body  130  reciprocates along the leftward/rightward moving track  120  one time, and the camera installation section  150  moves in an oval shape as a whole, even when there is no movement along the forward/rearward moving track  110 , the images can be photographed at various positions in the leftward/rightward and forward/rearward directions to photograph the three-dimensional moving picture having a large depth. 
         [0045]    Here, since a front portion marked by A of the camera installation section  150  is continuously directed to one point even when the horizontal rotary bar  140  is rotated, the camera installed at the camera installation section  150  can photograph a scene of the front side at various positions in the leftward/rightward and forward/rearward directions about a specified one point to photograph the three-dimensional moving picture having a large depth. 
         [0046]    A plurality of images can be photographed at various positions by leftward/rightward reciprocal movement of the movable body  130  and rotation of the horizontal rotary bar  140 , and the images are recognized in the brain as the three-dimensional moving picture having the large depth in the forward/rearward and leftward/rightward directions when the images are sequentially seen. 
         [0047]      FIG. 3  is a schematic view showing another operation of the apparatus according to the first embodiment of the present invention. 
         [0048]    In an operation shown in  FIG. 3 , while the horizontal rotary bar  140  is rotated in a clockwise direction by one rotation while the movable body  130  reciprocates along the leftward/rightward moving track  120  one time, the leftward/rightward moving track  120  reciprocates rearward and forward along the forward/rearward moving track  110  one time, and thus, the three-dimensional moving picture having a larger depth than the case of  FIG. 2  can be photographed while the camera installation section  150  moves like a very large circle as a whole. 
         [0049]    Specifically, the movable body  130  is disposed at the most right side of a starting position shown in  FIG. 3(   a ), the horizontal rotary bar  140  is also directed rightward, and the leftward/rightward moving track  120  is disposed at a center of the forward/rearward moving track  110 . 
         [0050]    Immediately after the photographing starts, in  FIG. 3(   b ), when the movable body  130  is moved leftward along the leftward/rightward moving track  120  and the horizontal rotary bar  140  is moved rearward while rotating in the clockwise direction, the leftward/rightward moving track  120  is moved toward a rear side of the forward/rearward moving track  110 . 
         [0051]    Next, the horizontal rotary bar  140  is also continuously rotated in the clockwise direction to be directed leftward while the movable body  130  is moved to the most left side of the leftward/rightward moving track  120  as shown in  FIG. 3(   e ), and the leftward/rightward moving track  120  moved forward again from the most rear side of the forward/rearward moving track  110  (see  FIG. 3(   c )) to be disposed at the center of the forward/rearward moving track  110 . 
         [0052]    In  FIGS. 3(   f ) to  3 ( i ), the movable body  130  is moved from the left side to the right side, the horizontal rotary bar  140  is rotated forward in the clockwise direction by a half rotation, and the leftward/rightward moving track  120  reciprocates along the forward/rearward moving track  110  in a forward direction. 
         [0053]    Here, since the front portion marked by A of the camera installation section  150  is continuously directed to one point of the front side even when the horizontal rotary bar  140  is rotated, the camera installed at the camera installation section  150  can photograph a scene of the front side at various positions in the leftward/rightward and forward/rearward directions about the specified one point to photograph the three-dimensional moving picture having a large depth. 
         [0054]    As described above, the plurality of images photographed by the camera during the process of leftward/rightward reciprocal movement of the movable body  130 , rotation of the horizontal rotary bar  140  and forward/rearward reciprocal movement of the leftward/rightward moving track  120  are recognized in the brain as the three-dimensional moving picture having the large depth in the forward/rearward and leftward/rightward directions. 
         [0055]    As shown in  FIGS. 2 and 3 , an operation range in which the three-dimensional moving picture photographing apparatus of the embodiment is moved is not particularly limited to the range in which the apparatus reciprocates between both ends of the forward/rearward moving track  110  and the leftward/rightward moving track  120 , and the operation range can be variously adjusted within the track according to a photographing purpose. Such a moving range may be adjusted by inputting a leftward/rightward reciprocating distance and a forward/rearward reciprocating distance according to necessity, or may be adjusted by a method of previously inputting a leftward/rightward reciprocating distance and a forward/rearward reciprocating distance, which are optimized for a specified case, and shifting a mode according to each circumstance. 
         [0056]    In addition, the operation of the three-dimensional moving picture photographing apparatus of the embodiment is not limited to that shown in  FIGS. 2 and 3 , but the forward/rearward movement, leftward/rightward movement, and rotation may be variously combined to obtain various effects. 
         [0057]    Sizes of the forward/rearward moving track  110 , the leftward/rightward moving track  120  and the horizontal rotary bar  140  of the embodiment are generally designed with reference to a distance between both eyes. However, since the operation range can be adjusted as described above, the sizes may be designed to be further increased to increase the depth in the three-dimensional moving picture. 
         [0058]      FIG. 4  is a schematic view showing a structure of a three-dimensional moving picture photographing apparatus according to a second embodiment of the present invention. 
         [0059]    The three-dimensional moving picture photographing apparatus of the embodiment includes a horizontal track constituted by a forward/rearward moving track  210  and a leftward/rightward moving track  220 , a movable body  230 , a vertical rotary bar  240  and a camera installation section  250 . 
         [0060]    The horizontal track includes the forward/rearward moving track  210  and the leftward/rightward moving track  220 , which are linearly formed, perpendicular to each other, and the movable body  230  moves forward/rearward and leftward/rightward by the forward/rearward moving track  210  and the leftward/rightward moving track  220 . Since the horizontal track is the same as that of the first embodiment, detailed description thereof will be omitted. 
         [0061]    In the embodiment, a column  232  extending upward from the movable body  230  is installed to not collide with the forward/rearward moving track  210  when the vertical rotary bar  240  is rotated, and one end of the vertical rotary bar  240  is connected to a front surface of an upper section of the column  232  via a rotary shaft  241 . 
         [0062]    The camera installation section  250  is connected to an opposite end of the vertical rotary bar  240 , and the camera installed at the camera installation section  250  of the opposite side is moved in a circular shape in a direction perpendicular to the ground when the vertical rotary bar  240  is rotated about the rotary shaft  241 . 
         [0063]    The camera installation section  250  is a section at which the camera configured to photograph moving pictures can be installed, and is moved in a circular shape in a direction perpendicular to the ground by rotation of the vertical rotary bar  240 . In particular, the camera installation section  250  of the embodiment is connected to the vertical rotary bar  240  via a rotary shaft  242  and rotated in an opposite direction of the vertical rotary bar  240  about the rotary shaft  242  according to rotation of the vertical rotary bar  240 , and thus, an upper side of the camera installation section  250  is directed upward. 
         [0064]    In addition, the lens of the camera installed at the camera installation section  250  is continuously directed to one point of a preset front side by adjusting an angle in a horizontal direction of the camera installation section  250  while the camera installation section  250  is rotated. Specifically, the lens of the camera can be directed to one point of the front side by adjusting the angle to be directed downward with reference to the rotary shaft  241  when the camera installation section  250  is disposed over the rotary shaft  241  using a three-axial apparatus or the like, adjusting the angle to be directed upward with reference to the rotary shaft  241  when the camera installation section  250  is disposed under the rotary shaft  241 , adjusting the angle to be directed rightward with reference to the rotary shaft  241  when the installation section  250  is disposed at a left side of the rotary shaft  241 , and adjusting the angle to be directed leftward with reference to the rotary shaft  241  when the camera installation section  250  is disposed at a right side of the rotary shaft  241 . 
         [0065]    The structure in which the upper side of the camera installation section  250  is directed to one point of the front side while being directed upward and the structure in which the camera is installed at the camera installation section  250  are not particularly limited, and all structures to which one of ordinary skill in the art can apply are possible. In addition, the camera installed at the three-dimensional moving picture photographing apparatus of the embodiment is not particularly limited as long as the camera can photograph moving pictures recognized as a moving picture due to an afterimage in the brain by photographing several to several hundreds of frames per second. 
         [0066]    In an operation of the apparatus according to the second embodiment, while the movable body  230  reciprocates in leftward/rightward directions or in leftward/rightward and forward/rearward directions by the forward/rearward moving track  210  and the leftward/rightward moving track  220 , the vertical rotary bar  240  is rotated and the camera installed at the camera installation section  250  is moved in a circular shape in a direction perpendicular to the ground. According to the above-mentioned operation, the camera can sequentially photograph the images at various positions in forward/rearward, leftward/rightward and upward/downward directions, and the images photographed as described above are recognized in the brain as the three-dimensional moving picture having a large depth in the upward/downward direction as well as in the forward/rearward and leftward/rightward directions. 
         [0067]    Since the operation range and shape in which the three-dimensional moving picture photographing apparatus of the embodiment is not particularly limited but variously adjusted are similar to that of the first embodiment, detailed description thereof will be omitted. 
         [0068]      FIG. 5  is a schematic view showing a structure of a three-dimensional moving picture photographing apparatus according to a third embodiment of the present invention. 
         [0069]    The three-dimensional moving picture photographing apparatus of the embodiment includes a horizontal track constituted by a forward/rearward moving track  310  and a leftward/rightward moving track  320 , a movable body  330 , a vertical track  340  and a camera installation section  350 . 
         [0070]    The horizontal track includes the forward/rearward moving track  310  and the leftward/rightward moving track  320 , which are linearly formed, disposed perpendicular to each other, and the movable body  330  is moved in forward/rearward and leftward/rightward directions by the forward/rearward moving track  310  and the leftward/rightward moving track  320 . Since the horizontal track is similar to that of the first and second embodiments, detailed description thereof will be omitted. 
         [0071]    In the embodiment, in order to increase the depth in the upward/downward directions, the vertical track  340  is vertically installed above the movable body  330 , and the camera installation section  350  is movable along the vertical track  340  in the upward/downward directions. 
         [0072]    The camera installed at the three-dimensional moving picture photographing apparatus of the embodiment is not particularly limited as long as the camera can photograph moving pictures recognized as a moving picture due to an afterimage in the brain by photographing several to several hundreds of frames per second. In addition, the structure in which the camera is installed at the camera installation section  350  is not particularly limited, and all structures to which one of ordinary skill in the art can apply are possible. 
         [0073]    In the operation of the apparatus according to the third embodiment, while the movable body  330  reciprocates in leftward/rightward directions or in leftward/rightward and forward/rearward directions by the forward/rearward moving track  310  and the leftward/rightward moving track  320 , the camera installation section  350  is moved along the vertical track  340  in upward/downward directions. Here, while the camera installation section  350  is moved in the upward/downward directions, the lens of the camera installed at the camera installation section  350  is continuously directed to one point of a preset front side by adjusting an angle in a horizontal direction of the camera installation section  350 . Specifically, the lens of the camera can be directed to one point of the front side by adjusting the angle to be directed downward with reference to a center of the vertical track  340  when the camera installation section  350  is disposed over the center of the vertical track  340  using a three-axial apparatus or the like, and adjusting the angle to be directed upward with reference to the center of the vertical track  340  when the camera installation section  350  is disposed under the center of the vertical track  340 . 
         [0074]    According to the operation, the camera can sequentially photograph the images at various positions in the forward/rearward, leftward/rightward and upward/downward directions, and the images photographed as described above are recognized in the brain as the three-dimensional moving picture having a large depth in the upward/downward directions as well as in the forward/rearward and leftward/rightward directions. 
         [0075]    Since the operation range and shape in which the three-dimensional moving picture photographing apparatus of the embodiment is not particularly limited but variously adjusted are similar to that of the first and second embodiments, detailed description thereof will be omitted. 
         [0076]      FIG. 6  is a schematic view showing a structure and an operation of a three-dimensional moving picture photographing apparatus according to a fourth embodiment of the present invention. 
         [0077]    The three-dimensional moving picture photographing apparatus of the embodiment includes a circular track  400 , a movable body  430  and a camera installation section  450 . 
         [0078]    The movable body  430  of the embodiment is moved along the circular track  400  in a circular shape, and the camera installation section  450  is connected to the movable body  430 . 
         [0079]    The camera installation section  450  is a section at which the camera configured to photograph moving pictures can be installed, and is moved with the movable body  430  in a circular shape. In particular, the camera installation section  450  of the embodiment is connected to the movable body  430  via a rotary shaft  431  and rotated in an opposite direction of the circular movement direction of the movable body  430  about the rotary shaft  431  according to circular movement of the movable body  430 , and thus, the camera installation section  450  is directed toward the front side. 
         [0080]    In addition, the lens of the camera installed at the camera installation section  450  is continuously directed to one point of a preset front side by adjusting rotation of the camera installation section  450 . Specifically, the lens of the camera can be directed to the one point of the front side by adjusting the angle to be directed rightward with reference to a center of the circular track  400  when the installation section  450  is disposed at a left side of the center of the circular track  400 , and adjusting the angle to be directed leftward with reference to the center of the circular track  400  when the camera installation section  450  is disposed at a right side of the center of the circular track  400 . 
         [0081]    As shown by a dotted line of  FIG. 6 , since the camera installation section  450  is also rotated about the rotary shaft  431  such that the front side marked by A of the camera installation section  450  is continuously directed to one point of the front side while the movable body  430  is moved along the circular track  400  in a circular shape, the camera installed at the camera installation section  450  can photograph a scene of the front side at various positions in the leftward/rightward and forward/rearward directions with reference to one point to photograph the three-dimensional moving picture having a large depth. 
         [0082]    The structure in which the camera installation section  450  is operated to be directed to one point of the front side and the structure in which the camera is installed at the camera installation section  450  are not particularly limited, and all structures to which one of ordinary skill in the art can apply are possible. 
         [0083]    In addition, the camera installed at the three-dimensional moving picture photographing apparatus of the embodiment is not particularly limited as long as the camera can photograph moving pictures recognized as a moving picture due to an afterimage in the brain by photographing several to several hundreds of frames per second. 
         [0084]    Meanwhile, the circular track  400  of the embodiment is formed of a resilient material, and may be modified into various oval shapes. 
         [0085]      FIG. 7  is a schematic view showing shapes to which a circular track of the fourth embodiment of the present invention is modified. 
         [0086]    In  FIG. 7 , as examples of varying the shape of the circular track  400 , a shape in which the circular track  400  is varied into an oval shape elongated in the forward/rearward directions and an oval shape elongated in the leftward/rightward directions by adjusting lengths of a forward/rearward adjustment shaft  410  and a leftward/rightward adjustment shaft  420  is shown. The method of adjusting the lengths of the forward/rearward adjustment shaft  410  and the leftward/rightward adjustment shaft  420  may be variously configured using a linear motor or rotating a threaded shaft. 
         [0087]    In addition, the method of modifying the shape of the circular track is not particularly limited, but all structures to which one of ordinary skill in the art can apply are possible. 
         [0088]    The exemplary embodiments of the three-dimensional moving picture photographing apparatus according to the present invention have been described. The three-dimensional moving picture photographing apparatus is configured to be used by attaching a separately produced moving picture photographing camera. 
         [0089]    However, the track according to the embodiment moving in the forward/rearward, leftward/rightward and/or upward/downward directions may be applied to the three-dimensional moving picture photographing camera included in the housing. 
         [0090]    In recent times, along with development of the digital camera technology, the lens and the image sensor has been miniaturized. Accordingly, in the first to fourth embodiments, the camera in which the photographing unit including the lens and the image sensor is installed at the position of the camera installation section  150 ,  250 ,  350  or  450 , and image data photographed by the image sensor is transmitted to a memory unit in a wired or wireless manner to be stored may be provided. 
         [0091]    In particular, while a housing, a memory, and so on, are included in the camera to increase a volume thereof when a separately produced camera is used, since the volume is not increased when the photographing unit is constituted by the minimum number of parts including the lens and the image sensor, a camera in which a track, a photographing unit, a memory unit, and so on, are installed in one housing can be manufactured. 
         [0092]    The three-dimensional moving picture photographing camera according to the embodiment of the present invention is characterized in that the photographing unit including the lens and the image sensor is previously mounted on the three-dimensional moving picture photographing apparatus and installed in one housing, and components of a general camera can be applied to the components related to the configuration and the operation of the other cameras. Accordingly, detailed description of the configuration and the operation of the camera will be omitted. 
         [0093]    As described above, the three-dimensional moving picture photographing apparatus and camera of the present invention can photograph the three-dimensional moving picture having a large depth in the forward/rearward directions as the camera or the photographing unit photographs images at various positions in the leftward/rightward directions as well as the forward/rearward directions. 
         [0094]    In particular, in some of the embodiments, as the images are photographed at various positions in the upward/downward directions as well as the leftward/rightward and forward/rearward directions, the three-dimensional moving picture having a large depth in the upward/downward direction can be photographed. 
         [0095]    Embodiments of the invention have been discussed above with reference to the accompanying drawings. However, those skilled in the art will readily appreciate that the detailed description given herein with respect to these figures is for explanatory purposes as the invention extends beyond these limited embodiments. For example, it should be appreciated that those skilled in the art will, in light of the teachings of the present invention, recognize a multiplicity of alternate and suitable approaches, depending upon the needs of the particular application, to implement the functionality of any given detail described herein, beyond the particular implementation choices in the following embodiments described and shown. That is, there are numerous modifications and variations of the invention that are too numerous to be listed but that all fit within the scope of the invention.
