Description

TECHNICAL FIELD [0001] The present invention relates to a photographing method using a camera device,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera device and a photographing method using the same, and more particularly, to a technique for facilitating utilization of an image when photographing the same subject using a plurality of cameras.

Currently used still image or moving image cameras operate independently. For example, if you shoot the same subject with two cameras, each camera's images will be saved independently.

Although it is possible to synthesize images using special software, it is generally difficult to synthesize these two photographs because there is no function to match the respective shooting times.

In the case of the three-dimensional photographing in which the subject is displayed while rotating, the shutter of each camera is connected to a single device by a wire, and the photograph is taken by pressing the shutter at the same time. Then, the photographs in which the person is independently photographed, Connect other pictures to create a three-dimensional linked image. This is because there is no function to connect cameras and operate at exactly the same time. In this case, additional external devices are required for shooting and much effort is required for installation and movement.

In addition, frequent wireless communication is required when using wireless communication for time synchronization. In particular, when high precision time is required, the amount of communication is increased in proportion to the precision, which requires a large amount of calculation and high power consumption. This may cause a problem of shortening the camera operation time for a battery-dependent camera.

In addition, since the communication device is greatly influenced by the surrounding environment, it may cause many obstacles to communication on neighboring devices, and the accuracy of the time synchronization of the camera is deteriorated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, in order to facilitate a person skilled in the art to easily carry out the technical idea of the present invention.

FIG. 1 is a view showing a plurality of cameras for photographing a single subject.

Referring to FIG. 1, there is a moving subject 10, and there are a plurality of cameras 15 for photographing one subject 10 at different positions. The plurality of cameras 15 photograph one object at different positions. In addition, a video image captured by a plurality of cameras can be edited and combined to generate a three-dimensional linked image.

FIG. 2 is a block diagram showing a camera device according to the present invention. FIG. 2 illustrates a camera device that can be applied when a single subject is photographed by a plurality of cameras as shown in FIG.

2, the camera apparatus 100 includes a time synchronization receiving unit 105, a timer unit 110, a control unit 115, a photographing unit 120, and a storage unit 130.

First, the time synchronization receiving unit 105 receives the synchronization signal from the input device 140 for time synchronization and synchronizes the time of a plurality of cameras ('15' in FIG. 1). A global positioning system (GPS) satellite signal may be used as the input device 140. The time synchronization receiving unit 105 may receive GPS satellite signals and synchronize the cameras 15 with GPS time. In this case, even when the plurality of cameras 15 are spaced apart from each other by a predetermined distance, the GPS satellite signals received by the respective time synchronization receiving units 105 are the same, and thus the GPS satellite signals can be received at the same time. These GPS satellite signals provide high precision time in addition to latitude and longitude coordinates on earth. Here, the GPS satellite signal is described as an example of the input device 140, and the input device 140 is not limited thereto.

In the timer section 110, a photographing operation schedule of the camera is set. The photographing operation schedule is set based on the synchronization time received by the time synchronization receiving unit 105. [ The photographing operation schedule includes the photographing start time, photographing end time, photographing period, and photographing progress time. For example, the shooting start time may be set to 1:20 and 21.00 seconds on September 30, 2013, and the shooting end time may be set to be 31.00 seconds on September 30, 2013.

Instead of setting the shooting end time, the shooting progress time from the shooting start time can be set. For example, you can set it to 10 seconds from 21.00 seconds at 1:20 on September 30, 2013. In addition, it is possible to set the shooting cycle to take 10 images per second.

The control unit 115 compares the photographing operation schedule set in the timer unit 110 with the current time input from the time synchronization receiving unit 105 to determine whether or not the photographing operation is performed. For example, if it is determined that the photographing start time, the photographing period, or the photographing progress time matches the current time in the preset photographing operation schedule, the photographing unit 120 transmits a photographing request signal. However, if it is determined that the preset photographing operation schedule and the current time do not match, the camera is kept in the standby state.

The control unit 115 periodically compares the preset shooting schedule with the current time period, and transmits a shooting termination signal to the shooting unit 120 when it is determined that the shooting termination time and the current time match in the preset shooting schedule.

The photographing unit 120 receives the photographing request signal from the control unit 115 and proceeds to photograph the subject, receives the photographing end signal, and ends the photographing of the subject.

The storage unit 130 stores image images taken by the respective cameras in the photographing unit 120. [ The video image stored in the storage unit 130 is stored by standard time.

It is possible to synthesize or edit a video image of standard time among video image images stored in the storage unit 130 through a separate editing device.

As described above, the present invention can synchronize a plurality of cameras at standard time and match the shooting times of a plurality of cameras equally to each other, thereby facilitating the synthesis or editing of the captured images.

3 is a flowchart showing a photographing method using a camera device according to the present invention.

A photographing method using the camera device will be described with reference to FIG.

First, the synchronization signal is received from the input device 140 and the shooting time of the camera 15 (FIG. 1) is synchronized (step S10). GPS can be used as the input device 140, and the time synchronization receiving unit 105 can receive GPS satellite signals. GPS provides high-precision time in addition to latitude and longitude coordinates on Earth. Since the GPS satellite signals are the same, the GPS satellite signals can be received at the same time.

As shown in FIG. 1, when the same subject 10 is photographed by a plurality of cameras 15, images photographed by the respective cameras are independently stored. At this time, if the synchronized GPS time is operated on, the plurality of cameras can operate at exactly the same time. Here, the GPS satellite signal is described as an example of the input device 140, and the input device 140 is not limited thereto.

Then, the timer section 110 sets the photographing operation schedules of the plurality of cameras 15 (step S20). The photographing operation schedule can be set by inputting the photographing start time, photographing end time, photographing period, and photographing progress time. Cameras synchronized to a specific standard time are operated in accordance with a predetermined shooting operation schedule. Then, the photographed images are recorded in standard time.

 For example, the photographing start time may be set at 1:20 and 21.00 seconds on September 30, 2013, and the photographing end time may be set to 31.00 seconds on September 30, 2013.

Alternatively, instead of setting the shooting end time, the shooting time and the shooting period from the shooting start time can be set. For example, the photographing start time may be set at 1:20:21:00 on September 30, 2013, the photographing time may be set to 10 seconds, and the photographing period may be set to ten photographs per second. Then, the camera will shoot 10 images per second for 10 seconds from 1:20:21:00 on September 30, 2013.

Next, the photographing operation schedule set in the timer unit 110 is compared with the current time to determine whether or not the photographing operation is performed (step S30). And transmits a photographing request signal to the photographing unit 120 when the preset photographing start time and the current time coincide with each other.

Subsequently, the photographing unit 120 receives the photographing request signal from the control unit 115 and photographs the subject (step S40). At this time, as shown in FIG. 4, a plurality of cameras 15 can simultaneously photograph one moving object 10. The plurality of cameras 15 can generate a three-dimensional image of the subject by photographing one subject 10 at different positions.

Then, the photographed image is stored in the storage unit 130 (step S50). All stored images are stored in standard time.

After that, the video image stored in the storage unit 130 is transmitted to the editing apparatus 135, and the images taken at the same time are edited by comparing the shooting time. At this time, since the photographed image image is stored in standard time, the photographed image can be synthesized and edited accurately and easily.

FIGS. 4A and 4B show an operation sequence for photographing a camera. FIG. 4A shows an operation sequence of a camera for moving image capture, and FIG. 4B shows an operation sequence of a camera for still image capture.

Referring to FIG. 4A, the operation sequence of the camera for capturing moving images will be described below. The moving picture photographing operation is performed based on the schedule set in the timer unit 110 by receiving the photographing start time and the photographing ending time from the timer unit 110. [ The camera 15 is kept in the standby state until the photographing is started.

Then, it is determined whether the current time received from the input device 140 matches the set time set in the timer unit 110 (step S100).

If it is determined that the current time received from the input device 140 matches the shooting start time set in the timer unit 110, the camera shooting proceeds (step S110). However, if it is determined that the current time received from the input device 140 does not match the set time set in the timer unit 110, the camera 15 maintains the standby state. The camera 15 continuously receives the current time from the input device 140 during the photographing and checks the current time.

Then, it is determined whether the current time matches the shooting end time set in the timer unit 110 (step S120). If it is determined that the current time matches the shooting end time set in the timer unit 110, the shooting ends. However, if it is determined that the photographing end time does not coincide with the photographing end time, the photographing operation is continued.

Referring to FIG. 4B, the operation sequence of the camera for still image shooting will be described as follows. The shooting start time, shooting end time, and shooting cycle may be set in the timer unit 110 at the time of still image shooting. In addition, the timer section 110 may be set with an imaging start time, an imaging period, and an imaging progress time.

The camera 15 is kept in the standby state until the photographing is started. It is determined whether the current time received from the input device 140 matches the set time set in the timer unit 110 (step S200).

If it is determined that the current time received from the input device 140 matches the shooting start time set in the timer unit 110, the camera shooting proceeds (step S210). However, if it is determined that the current time received from the input device 140 does not match the shooting start time set in the timer unit 110, the camera 15 is kept in the standby state. At this time, the camera 15 continuously receives the standard time from the input device 140 during the photographing and checks the current time.

Then, it is determined whether the current time matches the shooting end time set in the timer unit 110 (step S220). If it is determined that the current time matches the shooting end time set in the timer unit 110, the shooting ends. However, if it is determined that the current time does not coincide with the shooting end time, the next shooting time of the shooting operation schedule is confirmed (step S230). After confirming the next shooting time, it is determined whether the shooting time coincides with the current time (step S200).

As described above, the present invention has the effect of facilitating the synthesis and editing of photographed images by synchronizing a plurality of cameras with standard time and operating the camera according to the synchronized standard time.
