Description

TECHNICAL FIELD [0001] The present invention relates to a mobile terminal,

The present invention relates to a method of photographing a mobile terminal by setting a composition guide, and more particularly, to a method of photographing a mobile terminal by setting a background image and a pose silhouette The present invention relates to a method of photographing a mobile terminal,

Generally, the photographing is performed by pressing the shutter after the photographer sets the structure and the set value for the subject using an analog or digital camera.

Analog cameras are rarely used, except for some professional photographers and enthusiasts, due to the limited number of shots and the cost of film purchases and prints.

The digital camera uses the image sensor instead of the film and stores the digital image information in the memory. The digital camera can shoot as much as the memory capacity. Since the digital camera can view the picture through the display means or the computer monitor without printing, The photographer and the public are favorite. The digital camera is easy to switch freely between the automatic mode or some manual mode and the fully manual mode, and the built-in control unit controls the difference in contrast between the subject's focus and the surrounding background, the color temperature difference, the aperture value, And a constant correction is applied so that the optimum photograph quality is obtained. Therefore, a photographer who uses a digital camera has a merit that satisfactory photograph quality that is not as good as an expert can be obtained even without expert knowledge in the field of photography. However, since digital cameras are not always carried around, there is a disadvantage that they can not be used when photographing is needed suddenly.

On the other hand, unlike a camera, a mobile terminal such as a smart phone equipped with a photographing function is always used for a phone call, so that it can take a picture whenever necessary.

The photographing method using the mobile terminal is almost the same as the above-described digital camera, and since the display screen is a large screen, it is much more convenient to check the quality of the preview image or the photographed image. In addition, most of the display screens are of the touch screen type, and the performance of the control unit is much higher than that of the general digital camera control unit, so that it is possible to process various additional functions.

However, in the case of photographing using a mobile terminal having various functions, when the holder of the mobile terminal requests the photographer to photograph the other person with the background image, There are many cases where the photographer does not have a proper mode to transmit the information correctly. Therefore, in this case, the photographer who has received the request does not receive the intention of the photographer himself (photographer) It is often the case that the composition or figure layout does not work properly.

However, there is not provided a photographing method that solves the drawbacks that occur when photographing through a mobile terminal as described above, so that there is a need for a photographing method in which communication between a photographer and a photographer can be accurately communicated to be.

FIG. 2 is a block diagram of a mobile terminal for performing the photographing method of FIG. 1 of the present invention. FIG. 4 is a diagram illustrating an example of a background composition guide mode according to an embodiment of the present invention, FIG. 5 illustrates an example of a person pose silhouette mode according to an embodiment of the present invention, 6 is a view illustrating an integrated guide mode according to an embodiment of the present invention.

Hereinafter, the description will be focused on a photographing method when a person having a mobile terminal directly sends a mobile terminal to another person (photographer) to ask for a photograph, not a general case of photographing a subject directly.

Hereinafter, the term " to-be-photographed person " refers to a person who wants to be photographed by delivering his / her mobile terminal to another person, and the term " photographer " means a person who has passed the mobile terminal from a person who owns the mobile terminal, And a pose silhouette is a guide that tells the other person to shoot with the information setting.

In the following description, the mobile terminal 1 refers to a smart phone which is typically operated by a driving OS. The mobile terminal 1 includes a camera phone including a camera lens and a flash for illumination, A display unit 20 such as an LCD, an AMOLED, a camera-driving application program, and a photographed image file. The memory 20 may include various types of storage devices such as a built-in or external flash memory A camera module (not shown) provided in the mobile terminal body, and a software module for controlling the camera module and the application program, And a control unit 40 for storing the photographed image file . More specifically, the configuration and operation principle of the mobile terminal are well known in the art and will not be described below for the sake of explanation.

As shown, the present invention firstly has a step S100 of activating the background composition guide mode shown in Fig. 4 in the basic photographing mode of Fig. In the change from the basic photographing mode to the background guide mode, when the second icon is touched at the lower part of FIG. 3 according to an embodiment, the lower second icon is changed to a floating state as shown in FIG. However, it is needless to say that such an icon or position does not limit the present invention but can be variously changed.

This step is a step for generating guide information to be photographed by a photographer who is a mobile terminal holder to a photographer (another person). The photographer can select a camera icon displayed on the display unit of the mobile terminal or a physical button of the mobile terminal , Power button, volume control button, etc.) to activate the camera program and enter the background composition guide mode in the normal mode. When this process is performed, a camera application program among a plurality of application programs stored in the mobile terminal is loaded on the control unit, and a procedure for guide shooting is performed.

Thereafter, in step S200, the captured background image is converted into a semitransparent state by pressing a camera shutter in a desired background image on the preview image. This step is a step of forming guide background information for the photographer to give to the photographer in accordance with the composition of the photograph of the photographer in the activated background composition guide mode. After confirming the background displayed in the preview while moving the mobile terminal, So as to convert the captured background picture into a translucent state so that it can be seen with the preview.

The state of the captured composition background picture can be confirmed by displaying a square frame screen and a shutter formed on the display unit as a figure having a black frame line according to an embodiment.

The captured background picture is temporarily stored in the memory unit after the transparency is adjusted so that the preview picture can be viewed by the control unit.

The photo file stored in the memory unit can be utilized at any time before the final photo is completed or additionally, before the background picture is taken or the icon command is issued, the storage state is maintained.

Preferably, the semitransparent background photo is preferably resident in the RAM. However, it can be stored in the internal memory unit to conserve resources of the memory area. The internal memory part can be replaced with RAM because it can read and write faster than a flash memory part such as a general SD card.

In addition, the translucent background photo may be stored in the same internal memory as the last photographed photo file, or may be configured such that a separate memory area is allocated to an area memory unit specific to the background photo,

The semi-transparent state background photograph is controlled to be automatically deleted when the photographing of the final photograph is completed.

The semitransparent state is defined as a state in which the semitransparent state is entered if the preview image displayed on the display unit can be seen while the transparency is adjusted to 100% or less. The default mode is configured to display the set value in a translucent manner.

Transparency can include steps that can be adjusted as needed. In a method of controlling translucency in a configuration according to an exemplary embodiment, the translucency adjusting bar may be activated by tapping a display unit or an icon formed at an arbitrary point, and dragging the translucency to a required degree of transparency.

And preferably has a transparency of 40 to 60%. If the value is lower than the lower limit, the captured image is not visible. If the upper limit is higher than the upper limit, the preview image is not visible.

And then activating the person pose silhouette mode (S300) as shown in FIG. 5 in a state where the translucent state background composition picture is plotted on the display unit and overlapped with the preview picture.

At this time, if it is determined that the matching between the active portrait pose silhouette mode and the translucent background background picture is not appropriate, the cancel icon or the return icon displayed at an arbitrary position on the display is touched (S200) You can get a background picture of translucent state background. The cancel icon or the return icon according to one embodiment shown in FIG. 5 is displayed on the lower side on the right side. Such an icon shape or position does not specify the present invention, but can be formed in various display forms or positions.

The step of activating the person pose silhouette mode may include selecting one of the various pose silhouettes stored in the memory unit and plotting the background pose silhouette on the background picture when the basic mode is selected.

The pose silhouette that can be selected is a plurality of pre-stored person pose silhouettes, for example, a frontal view, a side posture, a sitting posture on the front, a posture oblique on the front, It is a pose silhouette that stores the most preferred or used postures. It is a linear figure expressing the outline of human body. In the present invention, various pose silhouettes are formed instead of simple silhouette icons because the quality of the pictures can be changed according to the background composition according to the person's pose. If the icons are positioned on the background structure, It is very important to provide accurate pose silhouette because the satisfaction of the photographer can be changed.

It is also important that the pose silhouette of the present invention is composed of a silhouette figure in the form of an outline. The reason why the outline shape pose silhouette figure is used without using the solid type icon or the solid type silhouette is that the silhouette of the present invention is filled in the outline of the silhouette rather than the simple icon. This is because the pose and size of the background and the figure set by the person to be photographed are completed perfectly.

This outline type pose silhouette allows the photographer to set the preview background to a semi-transparent background composition photograph without any special thought, and to shoot the perfect pose and size within the outline of the silhouette, Quality can be provided.

In addition, the user can selectively retrieve his / her favorite photographs as needed, including a pose silhouette shape storing step.

In addition, when the user selects one of the stored sample pose silhouettes, the person pose silhouette mode is floated on the background composition picture. The floating pose silhouette adjusts the floating rectangular frame to move, rotate, In a desired figure.

Meanwhile, the personality pose silhouette mode step may further include a pose silhouette placement recommendation mode by analyzing a background composition picture in which the control unit is translucent in a deformation mode before the basic mode.

This step guides the photographer to position the pose silhouette at the optimum position. This step is necessary if you do not have background knowledge about the picture when you take a photo, you can get a picture that does not match the background and portrait by selecting the wrong figure layout and size. It is often because you can not reproduce the scenery of the scenery, including the tourist spot or the weather and the seasons.

In order to prevent this, the present invention analyzes the digital pixel information such as the outline extraction or the color distribution by taking the background image of the semitransparent state composition image so that the main frame composition of the background is the same as that of the river, mountain, sea, building, roadside road, By analyzing the representative form, it guides the optimal golden ratio or the most balanced figure arrangement in the photograph composition.

At this time, the controller can guide the size of the pose silhouette as well as the size of the pose silhouette, thereby helping to obtain a photograph having the optimum quality.

For example, by analyzing the background image of a semi-transparent state composition and analyzing whether there is a land or a space where a person can be located, one of the pose silhouettes stored only at a realistic position can be automatically selected, So that it can be displayed in a state in which the size is adjusted.

Of course, the photographer can use the pose silhouette that is displayed automatically afterwards.

You can also use either the pose silhouette placement or size by referring to the automatically displayed pose silhouette.

Also, it can freely adjust the position and size according to the adjustment method in the basic mode based on the automatically displayed.

Thereafter, a semi-transparent state background picture and a selected pose silhouette are fixed to generate an integrated guide mode as shown in FIG. 6 (S400).

In this step, the determined person pose silhouette mode is fixed to the guide background picture information in the semi-transparent state. When the integrated guide screen is created, the person to be photographed can deliver the mobile terminal to the photographer, State.

And a step (S500) of photographing the preview picture in accordance with the overlapped integrated guide picture. In this step, the photographer can confirm the background composition desired by the photographee and the position of the photographed person through the mobile terminal delivered from the photographed person, and has a preview screen and an integrated guide screen displayed on the display unit, You can shoot by pressing the camera shutter until the preview screen and the integrated guide screen are superimposed to show a single screen.

Through the steps described above, the photographer can always obtain the optimum photograph quality in which the intended photographer's background photograph and the portrait photograph are arranged.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims and their equivalents. Of course, such modifications are within the scope of the claims.
