Accordingly, it should be apparent to those skilled in the art that the following description of example embodiments of the present invention are provided for illustration purpose only and not for the purpose of limiting the invention as defined by the appended claims and their equivalents.

More particularly, the present disclosure relates to a method and an apparatus for enabling to take a self-portrait picture via a predetermined user input instead of inputting an exclusive button for taking a self-portrait picture.

Hereinafter, a method and an apparatus for a self-camera image capturing are described. Though a self-camera image capturing indicates a self-portrait image capturing, the present disclosure is applicable to other general camera image capturing. A user input in the present disclosure includes both a user's touch and a user's input other than the user's touch.

FIGS. 1A-C illustrate a user input operation for enabling a user to perform the self-camera image capturing conveniently and stably in a mobile terminal according to an example embodiment of the present disclosure.

Referring to FIGS. 1A-C, a special key for the self-camera image capturing is not provided. Instead, when a specific user input is detected on a preview screen, the image capturing is performed.

That is, when a user performs a certain motion on a preview screen with his finger, the image capturing is performed. In FIGS. 1A-C, the certain motion is “V”. The certain motion in FIGS. 1A-C can be designated by the user. In addition, a user-designated certain motion setting is performed via an exclusive menu provided to the mobile terminal, and the user performs the certain motion on a touch screen of the mobile terminal to configure the certain motion.

First, in FIG. 1A, the user takes a posture for the self-camera image capturing, and enters a user input in a lower diagonal direction in order to input “V” on the screen, that is, the preview screen.

After that, in FIG. 1B, the user touches his/her finger on the screen, that is, the preview screen, and stands by for a predetermined time. The predetermined time is for improving the accuracy of “V” input recognition. At this point, the camera enters a half shutter mode.

After that, in FIG. 1C, the user performs an input in an upper diagonal direction in order to complete an input “V” on the screen, that is, the preview screen. Then, the camera image capturing is performed.

FIGS. 2A-C is a second view illustrating a user input operation for enabling a user to perform the self-camera image capturing conveniently and stably in a mobile terminal according to another example embodiment of the present disclosure.

Referring to FIGS. 2A-C, a special key for the self-camera image capturing is not provided. Instead, when a certain user input is detected on a preview screen, the image capturing is performed.

In FIGS. 2A-C, when a user enters a user input on the preview screen (FIG. 2A), a popup menu appears (FIG. 2B). The popup menu is shown on a popup. When the user provides a user input to the popup, a picture is taken (FIG. 2C).

That is, the popup can be located on a position where a user can provide a user input conveniently.

FIG. 3 illustrates a process for allowing a user to take a self-portrait picture conveniently and stably in a mobile terminal according to an example embodiment of the present disclosure.

Referring to FIG. 3, when the mobile terminal enters a self-portrait image capturing mode (step 305) and then detects a user input 1 (step 310), the mobile terminal determines the validity of the user input 1 (step 315). An example of determining the validity of the user input 1 is described below.

A step of determining whether the user input 1 is valid can include determining whether the position (ex: x, y coordinates) of a user input and the length of the user input in FIG. 1A are between respective upper and lower thresholds, and determining whether the standby time shown in FIG. 1B is between another upper and lower thresholds. In addition, the upper threshold and the lower threshold can be set by the user beforehand or can be a predetermined value. Alternatively, an algorithm for determining the validity of the user input 1 can be a generally suitable known algorithm.

When the user input 1 is valid (step 315), the mobile terminal enters a half shutter mode (step 320).

When the user input 1 is not detected (step 310) or the user input 1 is not valid (step 315), the mobile terminal monitors whether the user input 1 is detected again (step 310).

After that, when the mobile terminal detects a user input 2 (step 325), the mobile terminal determines whether the user input 2 is valid (step 330).

A step of determining whether the user input 2 is valid can include determining whether the position (x, y coordinates) of a user input and the length of the user input in FIG. 1C are between respective upper and lower thresholds. In addition, the upper and lower thresholds can be configured by the user beforehand or can be a predetermined value. Alternatively, an algorithm for determining the validity of the user input 2 can adopt any generally known suitable algorithm.

When the user input 2 is valid (step 330), the mobile terminal takes a picture (step 335).

When the user input 2 is not detected (step 325) or the user input 2 is not valid (step 330), the mobile terminal monitors whether the user input 2 is detected again (step 325).

After that, the mobile terminal displays a taken image (i.e., an image captured by the mobile terminal) (step 340), and when an instruction to store the taken image is received from the user (step 345), the mobile terminal stores the taken image (step 350).

FIG. 4 illustrates a process for allowing a user to take a self-portrait picture conveniently and stably in a mobile terminal according to another example embodiment of the present disclosure.

Referring to FIG. 4, when the mobile terminal enters a self-portrait image capturing mode (step 405) and then detects a user-defined user input 1 (step 410), the mobile terminal determines whether the user-defined user input 1 is valid (step 415).

Here, the user-defined user input 1 indicates a user input pattern defined by the user. When the user-defined user input 1 is valid (step 415), the mobile terminal enters a half-shutter mode (step 420).

When the user-defined user input 1 is not detected (step 410), or the user-defined user input 1 is not valid (step 415), the mobile terminal monitors whether the user-defined user input 1 is detected again (step 410).

After that, when the mobile terminal detects a user-defined user input 2 (step 425), the mobile terminal determines whether the user-defined user input 2 is valid (step 430).

Here, the user-defined user input 2 indicates a user input pattern defined by the user.

An algorithm for determining whether the user-defined user input 1 and the user-defined user input 2 are valid can be the algorithm described in association to FIG. 3, or any other generally known suitable algorithm.

When the user-defined user input 2 is valid (step 430), the mobile terminal takes a picture (step 435).

When the user-defined user input 2 is not detected (step 425), or the user-defined user input 2 is not valid (step 430), the mobile terminal monitors whether the user-defined user input 2 is detected again (step 425).

After that, the mobile terminal displays a taken image (i.e., an image taken by the mobile terminal) (step 440) and when an instruction to store the taken image is received from the user (step 445), the mobile terminal stores the taken image (step 450).

FIG. 5 illustrates a process for allowing a user to perform a self-camera image capturing conveniently and stably in a mobile terminal according to still another example embodiment of the present disclosure.

Referring to FIG. 5, when the mobile terminal enters a self-camera image capturing mode (step 505) and then detects a user input 1 on a screen (step 510), the mobile terminal displays a popup (step 515). Here, the popup locates at a position at which the user entered a user input on the screen.

After that, the mobile terminal enters a half shutter mode (step 525).

Then, when detecting a user input with respect to the popup (step 530), the mobile terminal takes a picture (step 535).

When not detecting the user input with respect to the popup (step 530), the mobile terminal monitors whether a user input with respect to the popup is detected again.

After that, the mobile terminal displays a taken image (i.e., an image taken by the mobile terminal) (step 540), and a command to store the taken image is received from the user (step 545), the mobile terminal stores the taken image (step 550).

FIG. 6 illustrates a process for indicating a half shutter mode according to an example embodiment of the present disclosure.

Referring to FIG. 6, when successfully detecting the user input 1, the mobile terminal enters a half shutter mode. In this example, when the mobile terminal informs the user using the mobile terminal of that the mobile terminal enters the half shutter mode, more convenience can be provided to the user.

When successfully detecting the user input 1 (step 605), the mobile terminal enters the half shutter mode (step 610) and generates a half shutter mode output informing that the mobile terminal enters the half shutter mode (step 615).

The half shutter mode can be notified by voice or sounds, vibration, or a message on a screen.

In addition, the half shutter mode can be notified by a blinking of a Light Emitting Diode (LED) provided to the mobile terminal, or a blinking of a flash provided to the mobile terminal, which do not limit to the scope of the invention.

FIG. 7 illustrates a process for the image capturing by a detection of a user input 2 in a half shutter according to an example embodiment of the present disclosure.

Referring to FIG. 7, after outputting the half shutter mode (step 705), the mobile terminal makes a preparation for a detection of the user input 2 (step 710). The preparation for the detection of the user input 2 includes determining whether a process for detecting the user input 2 is configured to adopt an automatic image capturing mode.

When the automatic image capturing mode is adopted (step 715), the mobile terminal automatically performs the camera image capturing in a predetermined time (step 725). In this example, a counter time remaining until taking a picture can be displayed.

When the automatic picture taking mode is not configured (step 715), the mobile terminal determines whether the user input 2 is detected (step 720).

When detecting the user input 2 (step 720), the mobile terminal performs a camera image capturing (step 730).

The processes after this are the same as the above-described processes (ex: store a taken image).

When detecting the user input 2, instead of the user's operation of providing the user input on the screen of the mobile terminal, the mobile terminal determines whether predetermined voice or sound is detected, and when the predetermined voice or sound is detected, the mobile terminal can determine that the user input 2 has been detected.

In addition, when detecting the user input 2, the mobile terminal determines whether the user's specific gesture is input, and when the certain gesture is detected, the mobile terminal can determine that the user input 2 has been detected.

FIG. 8 illustrates a mobile terminal allowing a user to perform the self-camera image capturing conveniently and stably according to an example embodiment of the present disclosure.

Referring to FIG. 8, the mobile terminal includes a modem 810, a controller 820, a storage unit 830, a user input detector 840, a display unit 850, an input unit 860, and a camera 870. The controller 820 controls the user input detector 840. In addition, the user input detector 840 performs the self-camera image capturing using the camera 870.

The modem 810 serves as a module for communicating with other apparatuses, and includes a radio processor, a baseband processor, etc. The radio processor converts a signal received via an antenna into a baseband signal to provide the same to the baseband processor, and converts a baseband signal from the baseband processor into a Radio Frequency (RF) signal so that the signal can be transmitted on an actual RF path, to transmit the same via the antenna.

All types of RF communication protocols currently in use can be used as an RF communication protocol used by the modem. The controller 820 controls an overall operation of the mobile terminal, and more particularly, controls the user input detector 840 according to the present disclosure.

The storage unit 830 stores a program for controlling an overall operation of the mobile terminal and temporary data generated during execution of the program. Particularly, the storage unit 830 stores a taken or generated image according to an example embodiment of the present disclosure.

The display unit 850 displays an output of the controller 820, and can be a Liquid Crystal Display (LCD), for example.

The input unit 860 serves as a unit for receiving a user input, and is positioned on the display unit 850, and feeds the user input to the controller 820.

When the mobile terminal enters a self-camera image capturing mode and then detects the user input 1, the user input detector 840 determines whether the user input 1 is valid.

A step of determining whether the user input 1 is valid can include determining whether the position (ex: x, y coordinates) of a user input and the length of the user input in FIG. 1A is within the upper and lower thresholds, and determining whether the standby time in FIG. 1B is between the upper and lower thresholds. The upper threshold and the lower threshold can be configured by the user in advance or can be a predetermined value.

When the user input 1 is valid, the user input detector 840 enters a half shutter mode.

When the user input 1 is not detected, or the user input 1 is not valid, the user input detector 840 monitors whether the user input 1 is detected again.

After that, when detecting the user input 2, the user input detector 840 determines whether the user input 2 is valid. A step of determining whether the user input 2 is valid can include determining whether the position (x, y coordinates) of a user input and the length of the user input in FIG. 1C is between the upper and lower thresholds. Likewise, the upper thresholds and the lower thresholds can be set by the user in advance or can be a predetermined value. When the user input 2 is valid, the user input detector 840 takes a picture from a camera.

When the user input 2 is not detected, or the user input 2 is not valid, the user input detector 840 monitors whether the user input 2 is detected again.

After that, the user input detector 840 displays a taken image on the display unit 850, and when a user selects to store a taken image, the user input detector 840 stores the taken image in the storage unit 830.

After the mobile terminal enters a self-portrait picture mode, when detecting the user-defined user input 1, the user input detector 840 determines whether the user-defined user input 1 is valid. Here, the user-defined user input 1 is a user input pattern defined by the user. The position, the length, and the time of the user-defined user input 1, and the upper threshold and the lower threshold can be arbitrarily set by the user.

When the user-defined user input 1 is valid, the user input detector 840 enters a half shutter mode.

When the user-defined user input 1 is not detected, or the user-defined user input 1 is not valid, the user input detector 840 monitors whether the user-defined user input 1 is detected again.

After that, when detecting a user-defined user input 2, the user input detector 840 determines whether the user-defined user input 2 is valid. Here, the user-defined user input 2 is a user input pattern defined by the user. The position, and the length of the user-defined user input 2, and the upper threshold and the lower threshold can be arbitrarily set by the user.

When the user-defined user input 2 is valid, the user input detector 840 takes a picture from a camera.

When the user-defined user input 2 is not detected, or the user-defined user input 2 is not valid, the user input detector 840 monitors whether the user-defined user input 2 is detected again.

After that, the user input detector 840 displays a taken image on the display unit 850, and when a user selects to store the taken image, the user input detector 840 stores the taken image in the storage unit 830.

Alternatively, after the mobile terminal enters the self-camera mode, when the user input detector 840 detects a user input on the screen, the user input detector 840 displays a popup. Here, the popup locates at a position at which the user entered the user input on the screen.

After that, the user input detector 840 enters a half shutter mode (step 525).

After that, when detecting a user input with respect to the popup, the user input detector 840 performs the camera image capturing.

When not detecting the user input with respect to the popup, the user input detector 840 monitors whether the user input with respect to the popup is detected again.

After that, the mobile terminal displays a taken image on the display 850, and when a user determines to store the taken image, the mobile terminal stores the taken image in the storage unit 830.

When successfully detecting the user input 1, the user input detector 840 enters a half shutter mode. In this example, when the user input detector 840 informs the user who uses the mobile terminal that the user input detector 840 enters the half shutter mode, more convenience can be provided to the user.

That is, when successfully detecting the user input 1, the user input detector 840 enters a half shutter mode, and generates a half shutter mode notification informing that the user input detector 840 enters the half shutter mode.

Entering the half shutter mode can be notified by voice or sound, vibration, or a visual message on a screen.

In addition, entering the half shutter mode can be notified by a blinking of a Light Emitting Diode (LED) provided to the mobile terminal, or a blinking of a flash provided to the mobile terminal, which does not limit the scope of the invention.

After notifying of entering a half shutter mode, the user input detector 840 makes a preparation for detection of a user input 2. The preparation for the detection of the user input 2 includes determining whether a process for detecting the user input 2 is configured to adopt an automatic image capturing mode.

When the automatic image capturing mode is adopted, the user input detector 840 automatically takes a picture in a predetermined time. In this example, a counter showing a remaining time until taking a picture can be displayed.

When the automatic image capturing mode is not adopted, the user input detector 840 monitors whether the user input 2 is detected.

When detecting the user input 2, the user input detector 840 takes a picture from a camera.

The processes after this are the same as the above-described processes (ex: store a taken image).

When detecting the user input 2, instead of the user's operation of providing the user input on the screen of the mobile terminal, the user input detector 840 determines whether certain user's voice or sound is detected using an algorithm realized in advance, and when the certain user's voice or sound is detected, the user input detector 840 can determine that the user input 2 has been detected.

In addition, when detecting the user input 2, the mobile terminal determines whether the user's certain gesture is input, and when the certain gesture is detected, the mobile terminal can determine that the user input 2 has been detected.

The present disclosure allows a user to take a self-portrait picture in a stable posture, thereby providing a convenience to the user.

Although the invention has been shown and described with reference to certain example embodiments thereof, 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 by the appended claims and their equivalents. Therefore, the scope of the present invention should not be limited to the above-described embodiments but should be determined by not only the appended claims but also the equivalents thereof.
