Hereinafter, a method and system for generating multi-projection images” in accordance with embodiments of the present invention are described in detail with reference to the accompanying drawings. The embodiments to be described are provided in order for those skilled in the art to easily understand the technical spirit of the present invention, and the present invention is not limited to the embodiments. Furthermore, matters represented in the accompanying drawings have been diagrammed in order to easily describe the embodiments of the present invention, and the contents may be different from forms that are actually implemented.
Each of the elements represented herein is only an example for implementing the embodiments of the present invention. Accordingly, in other implementations of the present invention, different elements may be used without departing from the spirit and scope of the present invention. Furthermore, each element may be purely formed of a hardware or software element, but may also be implemented using a combination of various hardware and software elements that perform the same function.
Furthermore, an expression that some elements are “included” is an expression of an “open type”, and the expression simply denotes that the corresponding elements are present, but it should not be understood that additional elements are excluded.
Furthermore, an expression of a “multi-projection image” means an image that is played back through a plurality of projection planes (or a plurality of display devices) disposed around the seats for the audience and that is capable of improving a sense of immersion and 3D effect felt by audiences.
A method of generating multi-projection images in accordance with an embodiment of the present invention is described below with reference to FIGS. 2 to 10.
Referring to FIG. 2, the method of generating multi-projection images in accordance with an embodiment of the present invention may include controlling a plurality of different types of filming devices so that they are disposed at specific angles at step S11, controlling the shutter operations of the plurality of different types of filming devices in order to synchronize the plurality of different types of filming devices at step S12, controlling the plurality of different types of filming devices so that they perform filming operations in a plurality of viewpoint directions at step S13, and mapping images captured by the plurality of different types of filming devices to a spherical space or cylindrical space and generating images of respective planes at step S14.
At step S11, the plurality of different types of filming devices configured to perform filming operations in the plurality of viewpoint directions is controlled so that they are disposed at specific angles.
In this case, the meaning that the plurality of different types of filming devices is controlled so that they are disposed at the specific angles means that adjacent ones of filming devices forming the plurality of different types of filming devices are driven in response to a control command so that they are disposed to form a specific included angle. For example, this means that adjacent ones of filming devices that form the plurality of different types of filming devices are disposed to form a specific included angle in response to a control command, as illustrated in FIG. 3.
Furthermore, the subject that controls the plurality of different types of filming devices so that they form a specific angle may be hardware having an operation processing ability. Such hardware may be independently present in a separate device form, for example, as a disposition control device. Such a control function may be performed by the synchronization control device to be described later.
Furthermore, the plurality of different types of filming devices means a filming device group including different types of filming devices. For example, the plurality of different types of filming devices may mean a filming device group that includes different types of filming devices, such as RED Epic and 5D Mark2. The plurality of different types of filming devices may include 5 filming devices. More specifically, the plurality of different types of filming devices may include a main filming device disposed at the center, two filming devices disposed on the left side of the main filming device, and two filming devices disposed on the right side of the main filming device. FIG. 3 illustrates that the plurality of different types of filming devices is implemented to include a main filming device disposed at the center, two filming devices disposed on the left side, and two filming devices disposed on the right side.
Furthermore, at step S11, the plurality of different types of filming devices may be disposed so that the angles of view of adjacent filming devices are overlapped. The reason for this is that if the angles of view of adjacent filming devices are overlapped, images captured by the adjacent filming devices can be overlapped and information about a relative relationship between the images captured by the different types of filming devices can be computed based on information about the overlap of the images. From FIG. 3, it may be seen that the plurality of different types of filming devices includes a main filming device 110, two filming devices 120 on the left side, and two filming devices 130 on the right side and the plurality of different types of filming devices is disposed so that the angles of view of adjacent filming devices 110-120, 120-120, 110-130, and 130-130 are overlapped. In this case, a region overlapped by adjacent filming devices may be different depending on the places where the filming devices are installed or lenses, but the filming devices may be disposed so that the region is 13~17%.
In a method of determining the overlap region of captured images, the following geometric criterion may be used.
As illustrated in FIG. 4, when the plurality of filming devices 110, 120, and 130 is viewed at the plane, points P1 to P5 at the same distance from the respective filming devices, for example, a distance of 10 m from the lenses of the respective filming devices in respective straight-line axes l1 to l5 that pass through the centers of the filming devices are determined. Furthermore, the filming devices are disposed so that two segments of a line that form the angle of view of each filming device and that are placed on the left side and right of the filming device pass through one point in the straight-line axis of the filming device.
If the filming devices are disposed as in FIG. 4, a filming image region overlapped between the filming devices can be regularly maintained and a ratio of the overlap region can be controlled based on the location of each point.
At step S11, the plurality of different types of filming devices may be disposed so that they implement an angle of view of 270 degrees or more. The reason for this is that only when the plurality of different types of filming devices implements an angle of view of 270 degrees or more, a screen of 270 degrees or more can be provided to audiences through multi-projection images and thus a 3D effect and a sense of immersion felt by the audiences can be maximized. From FIG. 3, it may be seen that the main filming device 110, the two filming devices 120 on the left side, and the two filming devices 130 on the right side implement an angle of view of 270 degrees or more.
Furthermore, at step S11, included angles between the plurality of different types of filming devices (i.e., an included angle between adjacent filming devices) may be controlled depending on the focal distance of a specific filming device. For example, if the plurality of different types of filming devices is implemented to include a main filming device, two filming devices on the left side, and two filming devices on the right side as illustrated in FIG. 3, included angles between the plurality of different types of filming devices may be controlled depending on the focal distance of the main filming device. More specifically, 1) if the focal distance of the main filming device is increased, the plurality of different types of filming devices may be disposed again so that an included angle between the main filming device and a filming device on the left side, an included angle between the main filming device and a filming device on the right side, an included angle between the filming devices on the left side, and an included angle between the filming devices on the right side are decreased. Furthermore, 2) if the focal distance of the main filming device is decreased, the plurality of different types of filming devices may be disposed again so that an included angle between the main filming device and a filming device on the left side, an included angle between the main filming device and a filming device on the right side, an included angle between the filming devices on the left side, and an included angle between the filming devices on the right side are increased. Simulations revealed that when the focal distance of the main filming device 110 and the focal distance of the left and right filming devices 120 and 130 are set to 24 mm and 16 mm, there are advantages in that the subsequent editing of an image is facilitated because a filming region is widened and a sense of visual stability is provided to audiences.
The focal distance of the main filming device 110, the length of a blind spot occurring when captured images are overlapped according to an included angle formed by filming devices, and the difficulty of a so-called stitching task, that is, a task for editing an overlap region, are described below.

Tables 1 to 4 illustrate classifications according to the focal distance of the main filming device. Each table illustrates the lengths of blind spots occurring when images are overlapped according to included angles between the filming devices and the difficulties of stitching tasks due to the lengths of the blind spots.
From Tables 1 to 4, it may be seen that an included angle between the filming devices is gradually decreased if the focal distance of the main filming device is increased and an included angle between the filming devices is gradually increased if the focal distance of the main filming device is decreased as described above. That is, if the focal distance of the main filming device is 24 mm, each filming device is disposed to have an included angle of 50 to 60 degrees. In contrast, if the focal distance of the main filming device is 50 mm, each filming device is disposed to have an included angle of 20 to 30 degrees.
From the tables, it may be seen that assuming that the focal distance of the main filming device is fixed to a specific value, if an included angle formed by filming devices is decreased, the length of a blind spot occurring when images are overlapped is reduced.
FIG. 5 illustrates included angles formed by the filming devices and the lengths of blind spots occurring when angles of view of the filming devices are overlapped. In particular, in FIG. 5, it is assumed that the focal distance of the main filming device is 32 mm and an included angle between the filming devices is 45 degrees.
A blind spot is generated when images captured by the plurality of filming devices are overlapped. The blind spot is generated due to the presence of an included angle formed by the filming devices and because the angles of view of the filming devices are not precisely matched.
Furthermore, from FIG. 5, it may be seen that the width of a blind spot region is increased, but the length of the blind spot is reduced if the size of an included angle between the filming devices is increased and the width of a blind spot region is reduced, but the length of the blind spot is increased if the size of an included angle between the filming devices is reduced.
The length of a blind spot region is related to a task for editing images captured by the plurality of filming devices, that is, a so-called stitching task. The stitching task refers to a task for editing images of the respective filming devices into a single screen. The stitching task is performed by a process of bringing the left and right faces of images into contact with each other. As the length of the blind spot region is increased when such a stitching task process is taken into consideration, that is, as the width of the blind spot region is narrowed, the stitching task is further facilitated because an image data load for editing is reduced from a viewpoint of a worker. As described above, from Tables 1 to 4 and FIG. 5, it may be seen that the difficulty of the stitching task is reduced as the length of a blind spot region is increased, that is, as the width of the blind spot region is reduced.

Table 5 illustrates that a blind spot region having a uniform width is generated the main filming device and the filming devices on the left side and right form a specific included angle.
FIG. 6 illustrates the angles of view and blind spot regions of filming devices when the focal distance of the main filming device is 32 mm and an included angle between the filming devices is 47 degrees. From FIG. 6, it may be seen that blind spot regions having a uniform width and not having a point of intersection are generated because segments of a line that form the angles of view of the filming devices go straight in parallel in a specific filming environment. If the focal distance and included angle of each filming device are set so that the blind spot region has uniform width as described above, there is an advantage in that the editing of a captured image becomes further facilitated. Furthermore, at step S11, the operation of disposing the plurality of different types of filming devices at specific angles (i.e., the adjacent filming devices are disposed to form a specific included angle) may be implemented using various methods. The operation may be implemented by the structural characteristics of a plurality of sliding bases in which the plurality of different types of filming devices is installed and a rig in which the plurality of sliding bases is formed to be rotatably moved.
For example, as illustrated in FIGS. 7 and 8, in the state in which the plurality of different types of filming devices 110, 120, 120, 130, and 130 has been installed in a plurality of sliding bases 210, 220, 220, 230, and 230 and the plurality of sliding bases 210, 220, 220, 230, and 230 has been installed in such a way as to move on a rig 240, the operation of disposing the plurality of different types of filming devices 110, 120, 120, 130, and 130 at specific angles (i.e., adjacent filming devices is disposed to form a specific included angle) may be implemented by a relative rotary motion between the plurality of sliding bases 210, 220, 220, 230, and 230. In such a case, the rig 240 may include a base plate 242 configured to form a basic body and a plurality of punched units 244 formed in the base plate and configured to have the plurality of sliding bases move. The plurality of sliding bases 210, 220, 220, 230, and 230 move along the paths formed by the punched units 244, thus being capable of implementing relative rotary motions for implementing included angles.
At step S12, in order to synchronize the plurality of different types of filming devices, the shutter operations of the plurality of different types of filming devices are controlled. More specifically, at step S12, the shutter operations of the plurality of different types of filming devices are controlled so that the plurality of different types of filming devices performs their filming operations in the state in which the plurality of different types of filming devices has been synchronized and start frames thereof have been matched.
In such a case, the control of the shutter operations may be performed in the state in which a difference between the operation speeds of the plurality of different types of filming devices has been taken into consideration. More specifically, in order to prevent problems in that the filming operations of types of filming devices are not synchronized and that the start frames of the filming devices are not matched due to a difference between the operation speeds of the filming devices although synchronized start shutter signals (i.e., signals that start the shutters) are transmitted, the shutter operations of the filming devices may be controlled in the state in which a difference between the operation speeds of the filming devices has been taken into consideration. A difference between the operation speeds of filming devices is caused by a difference between types of hardware used in the filming devices and a difference between types of software used in the filming devices. More specifically, a difference between the operation speeds of the filming devices is generated due to factors, such as the signal processing speed of a Central Processing Unit (CPU), a difference in the performance between types of hardware for communication, a difference between networks over which data is transmitted and received, and a difference in the performance between the rolling shutters of respective filming device (i.e., a difference in the frequency/speed of video that is recorded per second). Accordingly, in order to synchronize the filming devices, the start shutter signals may be transferred by taking the aforementioned factors into consideration.
For example, if the shutter operation speed of the main filming device is faster than the shutter operation speeds of the filming devices on the left side and the filming devices on the right side in FIG. 3, start shutter signals transmitted to the filming devices on the left side and the filming devices on the right side may be faster than a start shutter signal transmitted to the main filming device so that the filming operations of the filming devices are synchronized (i.e., a difference between the operation speeds is offset) and the start frames of the filming devices are matched with each other.
At step S13, the plurality of different types of filming devices performs their filming operations in the plurality of viewpoint directions. More specifically, at step S13, the plurality of different types of filming devices performs the filming operations in the plurality of viewpoint directions in the state in which the plurality of different types of filming devices has been disposed at specific angles and has been synchronized (i.e., in the state the start frames of the different types of filming devices have been matched with each other).
At step S14, multi-projection images are generated based on images captured by the plurality of different types of filming devices. More specifically, at step S14, images to be played back in the respective planes (e.g., respective projection planes or planes in which respective display devices have been installed) of a movie theater in which the “multi-projection system” has been constructed are generated based on the images captured by the plurality of different types of filming devices.
In such a case, image data obtained by the plurality of different types of filming devices may be converted into a form having a united color space and format. The color spaces and formats of the image data obtained by the plurality of different types of filming devices need to be united in order to integrate the image data and simultaneously control the image data in a subsequent image processing process (e.g., a process of mapping the image data to a space of a specific form). The image data obtained by the plurality of different types of filming devices may be implemented through a conversion program so that the format of the image data is compatible between the filming devices.
Furthermore, at step S14, the images captured by the plurality of different types of filming devices may be mapped to a spherical space or cylindrical space. After such mapping is performed, images to be played back in the respective planes (e.g., respective projection planes or planes in which respective display devices have been installed) of a movie theater may be generated.
In order to generate multi-projection images having a maximized sense of immersion and 3D effect felt by audiences, an image of each plane needs to be generated by taking the structure of a movie theater into consideration. The reason for this is that in the state in which source images (e.g., images captured by the plurality of different types of filming devices in the present invention) have been mapped to a spherical space or cylindrical space, image regions corresponding to the 3D arrangement states of respective planes (e.g., respective projection planes or planes in which respective display devices have been installed) can be easily specified and allocated.
FIG. 9 illustrates that images captured by the plurality of different types of filming devices are together mapped to a spherical space. More specifically, referring to FIG. 9, if the plurality of different types of filming devices includes a main filming device, two filming devices on the left side, and two filming devices on the right side, an image (i.e., an image A) captured by the main filming device, images (i.e., an image B and an image C) captured by the two filming devices on the left side, and images (i.e., an image D and an image E) captured by the two filming devices on the right side are together mapped to the spherical space. Furthermore, FIG. 10 illustrates that images captured by the plurality of different types of filming devices are together mapped to a cylindrical space. More specifically, referring to FIG. 10, if the plurality of different types of filming devices includes a main filming device, two filming devices on the left side, and two filming devices on the right side, an image (i.e., an image A) captured by the main filming device, images (i.e., an image B and an image C) captured by the two filming devices on the left side, and images (i.e., an image D and an image E) captured by the two filming devices on the right side are together mapped to the cylindrical space.
In the method of generating multi-projection images described above in accordance with an embodiment of the present invention, multi-projection images to be played back in the respective projection planes (or respective display devices) of a movie theater in which the multi-projection system has been constructed may be generated based on images captured by the plurality of different types of filming devices. More specifically, the method of generating multi-projection images may include disposing the plurality of different types of filming devices at specific angles, synchronizing the operations of the plurality of different types of filming devices, mapping images captured by the plurality of different types of filming devices to a specific space, specifying image regions corresponding to the arrangement states of respective projection planes (or display devices), and generating so-called “multi-projection images”.
A system for generating multi-projection images in accordance with an embodiment of the present invention is described below with reference to FIG. 11.
Referring to FIG. 11, the system for generating multi-projection images in accordance with an embodiment of the present invention may include a plurality of different types of filming devices disposed at specific angles and configured to perform their filming operations in a plurality of viewpoint directions in the state in which the different types of filming devices have been synchronized, a synchronization control device 300 configured to synchronize the plurality of different types of filming devices by controlling the shutter operations of the plurality of different types of filming devices, and an image processing device 400 configured to map images captured by the plurality of different types of filming devices to a spherical space or cylindrical space and to generate images of respective planes.
The plurality of different types of filming devices corresponds to a filming device group including different types of filming devices. For example, the plurality of different types of filming devices may mean a filming device group configured to include all of different types of filming devices, such as RED Epic and 5D Mark2. The plurality of different types of filming devices may include 5 filming devices. More specifically, the plurality of different types of filming devices may include a main filming device disposed at the center, two filming devices disposed on the left side of the main filming device, and two filming devices disposed on the right side of the main filming device. FIG. 11 illustrates that the plurality of different types of filming devices has been implemented to include the main filming device 110 disposed at the center, the two filming devices 120 disposed on the left side of the main filming device, and the two filming devices 130 disposed on the right side of the main filming device.
In this case, the meaning that the plurality of different types of filming devices is disposed at the specific angles means that adjacent ones of the plurality of different types of filming devices are disposed to form a specific included angle. For example, this means that adjacent ones of filming devices forming the plurality of different types of filming devices form a specific included angle, as illustrated in FIG. 11.
Furthermore, the plurality of different types of filming devices may be disposed so that the angles of view of adjacent filming devices are overlapped.
Furthermore, the plurality of different types of filming devices may be disposed so that they implement an angle of view of 270 degrees or more.
Furthermore, the included angles of the plurality of different types of filming devices (i.e., an included angle between adjacent filming devices) may be controlled depending on the focal distance of a specific filming device. More specifically, if the plurality of different types of filming devices is configured to include a main filming device, two filming devices on the left side of the main filming device, and two filming devices on the right side of the main filming device as illustrated in FIG. 3, the included angles of the plurality of different types of filming devices may be controlled depending on the focal distance of the main filming device.
An operation for disposing the plurality of different types of filming devices at specific angles (i.e., an operation for disposing adjacent filming devices so that they form a specific included angle) may be implemented by various methods, but may be implemented through the structural characteristics of the plurality of sliding bases in which the plurality of different types of filming devices is installed and the rig in which the plurality of sliding bases is formed in such a way as to rotatably move. For example, in the state in which the plurality of different types of filming devices 110, 120, 120, 130, and 130 has been installed in the plurality of sliding bases 210, 220, 220, 230, and 230 and the plurality of sliding bases 210, 220, 220, 230, and 230 has been installed in such a way as to move on the rig 240 as illustrated in FIGS. 7 and 8, the plurality of sliding bases 210, 220, 220, 230, and 230 may perform relative rotary motions so that the plurality of different types of filming devices 110, 120, 120, 130, and 130 are disposed at specific angles (i.e., adjacent filming devices are disposed to form a specific included angle). In such a case, the rig 240 may include the base plate 242 configured to form a basic body and the plurality of punched units 244 formed in the base plate and configured to have the plurality of sliding bases movable in the plurality of punched units 244. The plurality of sliding bases 210, 220, 220, 230, and 230 move along the paths formed by the plurality of punched units 244, thus being capable of implementing relative rotary motions for implementing included angles.
The synchronization control device 300 is configured to synchronize the plurality of different types of filming devices by controlling the shutter operations of the plurality of different types of filming devices. More specifically, the synchronization control device 300 is configured to control the shutter operations of the plurality of different types of filming devices so that the different types of filming devices perform their filming operations in the state in which they have been synchronized and the start frame thereof have been matched. To this end, the synchronization control device 300 may be connected to the different types of filming devices in a wired or wireless way, and it may send a control signal (e.g., a shutter start signal) to each filming device.
Furthermore, the synchronization control device 300 may control the shutter operations of the plurality of different types of filming devices by taking into consideration a difference between the operation speeds of the plurality of different types of filming devices. For example, if the shutter operation speed of the main filming device 110 is faster than the shutter operation speeds of the filming devices 120 on the left side and the filming devices 130 on the right side, the synchronization control device 300 may send start shutter signals faster to the filming devices 120 on the left side and the filming devices 130 on the right side than to the main filming device 110 in order to synchronize the filming operations of the filming devices (i.e., offset a difference between the operation speeds of the filming devices) and to match the start frames of the filming devices with each other.
Furthermore, the synchronization control device 300 may include at least one operation means and at least one storage means. In this case, the operation means may be a general-purpose CPU, but may be a programmable device (e.g., a CPLD or an FPGA), an ASIC, or a microcontroller chip implemented for a specific purpose. Furthermore, the storage means may be a volatile memory device, a non-volatile memory, a non-volatile electromagnetic storage device, or memory within the operation means.
The image processing device 400 is configured to generate multi-projection images based on images captured by the plurality of different types of filming devices. More specifically, the image processing device 400 is configured to generate images to be played back in the respective planes (i.e., projection plane or planes in which respective display devices have been installed) of a movie theater in which the multi-projection system has been constructed by performing an image processing process based on images captured by the plurality of different types of filming devices.
In such a case, the image processing device 400 may perform image processing for converting the color spaces and formats of image data obtained by the plurality of different types of filming devices. More specifically, the image processing device may convert the color spaces and format of obtained image data into a united form.
Furthermore, the image processing device 400 may map images, captured by the plurality of different types of filming devices, to a spherical space or cylindrical space together. After such mapping is performed, the image processing device 400 may generate images corresponding to the respective planes (e.g., respective projection planes or planes in which respective display devices have been installed) of a movie theater.
Furthermore, the image processing device 400 may include at least one operation means and at least one storage means. In this case, the operation means may be a general-purpose CPU, but may be a programmable device (e.g., a CPLD or an FPGA), an ASIC, or a microcontroller chip implemented for a specific purpose. Furthermore, the storage means may be a volatile memory device, a non-volatile memory, a non-volatile electromagnetic storage device, or memory within the operation means.
The system for generating multi-projection images in accordance with an embodiment of the present invention may further include a multi-projection image monitoring device or a multi-projection image simulation device in addition to the aforementioned devices.
The multi-projection image monitoring device is a device for playing back images, captured by the plurality of different types of filming devices, on a virtually reproduced movie theater. The multi-projection image monitoring device functions to enable a user to easily monitor multi-projection images obtained at a filming site.
In this case, a virtual movie theater reproduced on the multi-projection image monitoring device is implemented with reference to a movie theater information database (DB) included in the multi-projection image monitoring device, that is, a DB in which pieces of information (e.g., a screen standard and a movie theater standard) for reproducing a multi-projection movie theater have been stored.
Furthermore, the multi-projection image monitoring device may provide a variety of types of modes so that a user is able to play back an image in a virtual movie theater in various setting modes. For example, the multi-projection image monitoring device may play back multi-projection images by reproducing a virtual movie theater in a basic mode. In this case, the multi-projection image monitoring device may play back only images corresponding to the respective planes (e.g., projection planes on the left side, projection planes on the right side, and a projection plane at the center) of a multi-projection movie theater or may play back multi-projection images in a panorama image form. In this case, a user may increase or decrease the size of each multi-projection image or control the width and height of each multi-projection image by manipulating the multi-projection image monitoring device.
Furthermore, the multi-projection image monitoring device may enable a user to obtain image stitching information, such as information about what part of each image will be overlapped in a subsequent process of stitching images captured by the different types of filming devices and information about an angle between images when the images are overlapped. In this case, virtual stitching results implemented in the multi-projection image monitoring device may be stored in the form of data including numerical values and may be provided so that they are used when an actual stitching task is subsequently performed.
If the multi-projection image monitoring device is used as described above, a user can directly play back images, obtained at a filming site, in a virtual movie theater and monitor the images in real time. In particular, there is an advantage in that a user is able to continue to check whether an intended image complies with an intention of direction because each image can be played back in each mode. Furthermore, there is an advantage in that a content editing step is facilitated because a user may use the results of a stitching task in an actual content editing step using the multi-projection image monitoring device.
The multi-projection image simulation device is a device for playing back a produced multi-projection image in a virtually produced movie theater. In particular, the multi-projection image simulation device is the same as the multi-projection monitoring device in that it refers to information stored in a movie theater information DB when producing a multi-projection image in a virtual movie theater, but is different from the multi-projection monitoring device in that it may reproduce a more realistic and precise movie theater because more information (e.g., a screen standard, a movie theater standard, and interiors/structures/devices attached to the surface of a wall) to which reference is made as parameters.
Like the multi-projection image monitoring device, the multi-projection image simulation device may provide a variety of types of modes so that a multi-projection image can be played back in various setting mode. Furthermore, the multi-projection image simulation device may control a point of view so that a user is able to check the state of a multi-projection image that is being seen depending on a point of view of an audience, that is, the location of a seat.
If such a multi-projection image simulation device is used, there are advantages in that a user can virtually implement an actual screening environment and check the state of a multi-projection image that is played back and a third party, such as an advertiser, can also check the state of content that is being actually played back.
As described above, the system for generating multi-projection images in accordance with an embodiment of the present invention may include substantially the same technical characteristics as the method of generating multi-projection images in accordance with an embodiment of the present invention although they belong to different categories.
Accordingly, although not described in detail in order to avoid redundancy, the characteristics described in relation to the method of generating multi-projection images may also be deduced and applied to the system for generating multi-projection images in accordance with an embodiment of the present invention. Furthermore, on the contrary, the characteristics described in relation to the system for generating multi-projection images may also be deduced and applied to the method of generating multi-projection images.
