1 is a flowchart of a photographing method according to a first exemplary embodiment of the present invention.

Referring to FIG. 1, a first preferred embodiment of a photographing method according to the present invention will be described in detail as follows.

The photographing method according to the first exemplary embodiment of the present invention may be applicable to any mobile terminal having two or more cameras and two or more display units. However, two cameras and two cameras are provided for convenience of description. A description will be given assuming a mobile communication terminal having a display unit of Dual.

First, a preview of first and second external images received in real time through the first and second cameras provided in the terminal is provided [S100]. The user of the terminal may preview an external (or subject) image received through the first and second cameras through the process [S100]. Since the first and second cameras may be provided in various forms at various locations of the terminal, the first and second cameras may preview the external image in a direction desired by the user. The user may select a shooting time point through the preview.

Here, detailed features of the preview providing process [S100] for the first and second external images will be described in detail as follows.

The first and second external images may be displayed on the first and second display units provided in the terminal, respectively. That is, the first external image received from the first camera is displayed on the first display unit, and the second external image received from the second camera is displayed on the second display unit. Of course, the method may include displaying the first external image on the second display unit and the second external image on the first display unit.

Thereafter, the first and second still images are captured through the first and second cameras according to the still image photographing command signal received from the outside (S110). Generally, the still image photographing command signal will be received from a user through an input unit provided in the terminal.

Detailed features of the first and second still image capturing processes [S110] may be largely as follows.

(1) First, the method of photographing isometric manually. 2 is a flow chart of a manual ophthalmic imaging method according to the present invention.

After receiving a first photographing command signal for one of the first and second cameras [S200], a first still image is captured according to the first photographing command signal [S210].

Thereafter, after receiving a second photographing command signal for the other one of the first and second cameras [S220], a second still image is captured according to the second photographing command signal [S230].

According to the manual image pickup method, after the user has taken a picture through any one of the first and second cameras, the user can arbitrarily select a photographing time point of another picture to be combined with the photographed picture. However, the user must perform the shooting command for the first and second cameras twice (eg, press the camera shooting button twice).

(2) Second, it is a method of automatically photographing ishi (異 時). 3 is a flowchart of an automatic ocular photographing method according to the present invention.

After receiving a shooting command signal for any one of the first and second cameras [S300], a first still image is captured according to the shooting command signal [S310].

Thereafter, when a predetermined time elapses after receiving the photographing command signal, a second still image is captured through the other one of the first and second cameras [S320].

The predetermined time elapsed may be caused by various causes. First, the user may preset the time interval between two still images. In addition, when a zoom function of one of the first and second cameras is set, a difference in photographing time of the first and second cameras may occur to perform a zoom function.

According to the automatic image pickup method, two still images can be captured by performing a shooting command once (for example, pressing a camera shooting button once).

(3) Third, simultaneous shooting. 4 is a flowchart of a simultaneous shooting method according to the present invention. After receiving one shooting command signal [S400], according to the shooting command signal, simultaneously capture the first and second still images corresponding to the shooting command signal reception time through the first and second cameras. [S410].

Thereafter, the captured first and second still images are displayed (S120). Detailed features of the first and second still image display processes S120 may be largely as follows.

(1) First, the captured first and second still images may be displayed on the first and second display units, respectively.

(2) Second, both the captured first and second still images may be displayed on a preset display unit among the first and second display units. In this case, the form of displaying the first and second still images may vary. For example, the display may be split by displaying left / right or up / down, or by using a PIP function in which the first still image is the main screen (or sub-screen) and the second still image is the sub-screen (or main screen). It can also be displayed.

Thereafter, a third still image is obtained by synthesizing at least two or more of the captured first and second still images and still images previously stored in a memory provided in the terminal [S130].

The combination of still images participating in the synthesis may be various. That is, synthesis of the captured first and second still images, synthesis of any one of the captured first and second still images with a still image stored in the memory, and the captured first and second still images. And synthesis with the still image previously stored in the memory are possible.

Here, the still image pre-stored in the memory is a concept including various images such as various pictures, symbols, characters, and emoticons.

In addition, it is possible to synthesize a variety of ways according to the present invention, a representative example is as follows.

(1) First, when a specific region of one still image participating in the synthesis and a specific position of the remaining still image participating in the synthesis are selected, the specific region is synthesized at the specific position of the remaining still image and the third position is combined. Still images can be obtained. For example, this is when a portrait picture and a background picture are synthesized. That is, if it is assumed that the first still image is a background photograph and the second still image is a portrait photograph, only the person region may be cut out from the second still image and synthesized at a specific position of the background photograph.

(2) Second, at least one or more of the still images participating in the synthesis may be translucent and synthesized by overwriting each other. For example, when the first still image is a photograph of the sky and the second still image is a photograph of the user, the first still image may be synthesized by making the sky photograph or the user photograph or all of them translucent.

(3) Third, third still images may be obtained by arranging still images participating in the synthesis side by side horizontally or vertically. For example, the third still image may be obtained by photographing the first and second subjects in different directions from the terminal at the same time, and then arranging them horizontally or vertically side by side.

(4) Fourth, when still images participating in the synthesis are person images, each person image may be synthesized into one person image. For example, a boyfriend and girlfriend may be photographed at the same time or with a time difference, and then the faces of the boyfriend and girlfriend may be synthesized to create a baby picture.

Thereafter, the third still image is displayed (S140). That is, the synthesized third still image may be displayed on any one of the first and second display units. Which display unit to display may be set in advance.

Thereafter, the third still image is stored according to a user's selection [S150]. In addition, the user may transmit the synthesized third still image to the outside via a network. The network may be various, such as a mobile communication network, a wired / wireless integrated Internet network, a portable Internet network (WiBRO, WiMAX), a wireless Internet network (WiFi).

5 is a flowchart of a photographing method according to a second exemplary embodiment of the present invention.

Referring to FIG. 5, a second preferred embodiment of the photographing method according to the present invention will be described in detail as follows.

The photographing method according to the second preferred embodiment of the present invention is applicable to a mobile terminal having one or more cameras and two or more display units.

First, a preview of at least one or more of external images respectively received in real time through one or more cameras provided in the terminal is provided to any one of the first and second display units provided in the terminal, and the remaining display unit is provided. Displays a screen required for performing a separate function other than camera shooting on the screen [S500].

Herein, when the terminal includes the first and second cameras and receives the first and second external images in real time through the first and second cameras, detailed features of the preview providing process are as follows. There can be three major things together.

(1) First, when providing a preview of any one of the first and second external images to either one of the first and second display units, switching to the remaining external images according to a switch command signal received from the outside. Can be displayed. That is, assuming that the first display unit is a screen for previewing the camera, the second external image may be displayed by a switch command signal while displaying the first external image.

(2) Second, when providing a preview of any one of the first and second external images on either one of the first and second display units, the first and second external images are preset at a predetermined time interval. Can be displayed alternately one by one. The time interval may be preset by the user.

(3) Third, when providing a preview of both the first and second external images to any one of the first and second display units, one of the first and second external images is the main screen. The other one can be displayed as a sub screen. This feature is commonly referred to as Picture in Picture (PIP). In addition, the main screen and the sub-screen can be switched with each other.

On the other hand, even if the terminal has one or more cameras, when only the first camera is turned on and the remaining cameras are turned off, the first external device received through the first camera in the on state We will only provide a preview for the image. In the state where the first external image preview providing state is maintained, when the second camera that is in the off state is switched to the on state and the second external image is received, the third external image may be configured as described above. Can provide a preview.

Thereafter, the at least one still image is captured through the at least one camera according to at least one still image photographing command signal received from the outside [S510]. Here, in the case where the terminal includes the first and second cameras, detailed features of the still image capturing process [S510] are as described in the capturing method according to the first embodiment of the present invention. That is, there may be a manual iris photographing method, an automatic iris photographing method, and a simultaneous photographing method.

On the other hand, when the terminal has only one camera or even if it has two or more cameras, only one camera is turned on and the other cameras are turned off. Will capture one still image.

Thereafter, the captured one or more still images are displayed [S520]. Here, when the terminal is equipped with the first and second cameras, the detailed features of the still image display process [S520] are the same as those described in the first preferred embodiment of the present invention. However, when displaying the first and second still images captured from the first and second cameras, respectively, on the first and second display units, a screen required for performing a separate function other than the camera shooting displayed on the second display unit, respectively. Can be made to disappear temporarily or permanently.

Thereafter, at least two or more of the captured one or more still images stored in the memory of the terminal are synthesized to obtain a third still image [S530]. Detailed features of the still image pre-stored in the synthesis and memory are the same as those described in the first preferred embodiment of the present invention.

Thereafter, the third still image is displayed [S540], and the third still image is stored according to a user's selection [S550]. Details of the third still image display process [S540] and the storage process [S550] are the same as those described in the first preferred embodiment of the present invention.

6 and 7 illustrate examples of a photographing method according to the present invention implemented in a mobile communication terminal.

FIG. 6 illustrates a case in which the first and second external images are displayed on the first and second display units, respectively, and FIG. 7 illustrates both of the first and second external images on either one of the first and second display units. This is the case. That is, in the case of Figure 7, there is an advantage that can perform a separate function in addition to the camera shooting in the lower display.

First, when a predetermined photographing button provided in the terminal is pressed (once or twice) in the camera preview states 600 and 700, the first and second still images are captured (610 and 710). In the case of FIG. 6, the captured still image may be confirmed as a relatively larger screen than in the case of FIG. 7. In addition, in the case of FIG. 7, the camera preview may be continued even if the still image is captured.

The first and second still images are synthesized by a user's compositing command or automatic setting to obtain a third still image (620 and 720). In FIG. 6, although the preview of the first camera is illustrated in the upper display unit, the preview of the second camera may be set by setting.

Here, the real-time display form of the first and second external images received through the first and second cameras, the display form of the first and second still images, and the display form of the synthesized third still image may vary. Since it is possible, it is not limited only to the example of the imaging method shown in FIG. 6 and FIG.

In addition, although only the still image has been described above, a video recording method using two cameras may be possible by the same or similar method.
