Abstract

A method for generating video data and an image photographing device implementing the same are provided. The method includes acquiring annular panoramic video data by performing panoramic video photographing, selecting an extraction area from each frame of the annular panoramic video data, and generating video data by combining the extraction area selected from each frame.

Claims

1. A method for generating video data in an image photographing device, comprising:

acquiring annular panoramic video data by performing panoramic video photographing using a panorama annular lens system;

selecting an extraction area from each frame of the annular panoramic video data by automatically detecting an object included in the annular panoramic video data and selecting an area including the detected object from each frame of the annular panoramic video data, wherein a location of the object is different in each respective frame; and

generating video data by combining the extraction area including the detected object selected from each frame as arc-shaped video data in order to minimize a distortion correction.

2. The method of claim 1, wherein selecting the extraction area comprises selecting an area of the annular panoramic video data touched by a user on a touch screen.

3. The method of claim 1, wherein selecting extraction area comprises:

detecting a shaking of the image photographing device;

moving, when the detected shaking is horizontal shaking, a displayed area of the annular panoramic video data in a screen of the image photographing device; and

selecting, when the detected shaking is vertical shaking, an area on the annular panoramic video data displayed when vertical shaking is performed as the extraction area.

4. The method of claim 1,

wherein selecting the extraction area comprises, if an object included in the annular panoramic video data is selected according to a user touch, selecting an area including the selected object of each frame of the annular panoramic video data as the extraction area.

5. The method of claim 1, further comprising:

matching the annular panoramic video data with an adjacent map image; and

displaying the extraction area selected from the annular panoramic video data along with the adjacent map image, such that the extraction area is identified on the adjacent map image.

6. The method of claim 1, further comprising:

matching the annular panoramic video data with an adjacent map image; and

while playing back the generated video data, additionally playing back the adjacent map image, such that the extraction area of the video data is identified on the adjacent map image.

7. The method of claim 1, further comprising:

storing, while photographing the panoramic video, Global Positioning System (GPS) information of a location at which the panoramic video is photographed; and

additionally displaying, while playing back the generated video data, the location at which the extraction area of the video data is photographed, using the GPS information.

8. The method of claim 1, wherein acquiring the annular panoramic video data comprises:

acquiring first annular panoramic video data in a horizontal direction with respect to the surface of the earth; and

acquiring second annular panoramic video data in a perpendicular direction with respect to the surface of the earth, and

wherein the method further comprises providing spherical panoramic video data using the first and second annular panoramic video data.

9. An image photographing device, comprising:

a photographing unit for acquiring annular panoramic video data by performing panoramic video photographing using a panorama annular lens system;

a control unit for;

selecting an extraction area from each frame of the annular panoramic video data by automatically detecting an object included in the annular panoramic video data and selecting an area including the detected object from each frame of the annular panoramic video data, wherein a location of the object is different in each respective frame, and

generating video data by combining the extraction area including the detected object selected from each frame as arc-shaped video data in order to minimize a distortion correction; and

a display unit for displaying the generated video data.

10. The image photographing device of claim 9, further comprising a touch screen unit for detecting a touch of a user on the display unit,

wherein the control unit selects an area on the annular panoramic video data at which a user touch is made.

11. The image photographing device of claim 9, further comprising a motion detecting unit for detecting a shaking of the image photographing device,

wherein, when the motion detecting unit detects a horizontal shaking of the image photographing device, and the control unit moves a displayed area of the annular panoramic video data on the display unit, and

wherein, when the motion detecting unit detects a vertical shaking of the image photographing device, and the control unit selects an area on the annular panoramic video data displayed when the vertical shaking is performed as the extraction area.

12. The image photographing device of claim 9, further comprising a touch screen unit for detecting a touch of a user on the display unit,

wherein if an object included in the annular panoramic video data is selected according to a user touch, the control unit selects an area including the selected object of each frame of the annular panoramic video data as the extraction area.

13. The image photographing device of claim 9, wherein the control unit matches the annular panoramic video data with an adjacent map image, and controls so that the extraction area selected from the annular panoramic video data is displayed along with the adjacent map image, such that the extraction area is identified on the adjacent map image.

14. The image photographing device of claim 9, wherein the control unit matches the annular panoramic video data with an adjacent map image, and controls the display unit such that, while the generated video data is played back, the adjacent map image on which the extraction area of the video data is identified is additionally played back.

15. The image photographing device of claim 9, further comprising a storage unit, wherein the control unit controls such that, while the panoramic video is photographed, Global Positioning System (GPS) information of a location at which the panoramic video is photographed is stored, and while the generated video data is played back, the location at which the extraction area of the video data is photographed is additionally played back using the GPS information.

16. The image photographing device of claim 9, wherein the photographing unit acquires first annular panoramic video data in a horizontal direction with respect to the surface of the earth, and acquires second annular panoramic video data in a perpendicular direction with respect to the surface of the earth, and the control unit provides spherical panoramic video data using the first and second annular panoramic video data.
