The memory 270, 204 may include additional modules (instructions) in addition to the modules described above. Or, if necessary, some modules (instructions) may not be used.

In relation to the present invention, the application module includes instructions for enlarging and reducing the screen using a single gesture in the electronic device of the present invention (see FIGS. 3 to 5 below).

According to an embodiment of the present disclosure, a command for enlarging and reducing a screen using a single gesture in the electronic device of the present invention detects a user's first semi-circle or semi-ellipse gesture (see FIGS. 6 (a) to 6 (b) and 7). (a) to 7 (b)), it is determined whether the detected gesture corresponds to the first semicircle or semi-ellipse pattern in the clockwise direction, and the detected gesture corresponds to the first semicircle or semi-ellipse pattern in the clockwise direction. When the first screen is enlarged and displayed in proportion to the detected radius of the first semicircle or the radius of the long axis or short axis of the semi-ellipse (FIGS. 6 (a) to 6 (b)), the detected first The first screen is reduced and displayed in proportion to the radius of the semicircle or the radius of the long axis or short axis of the semi-ellipse (and referring to FIGS. 7A to 7B), and the electronic device is a second semicircle or half by the user. Determines whether an ellipse gesture is detected, and the second semicircle When to be semi-elliptical gesture, in accordance with the arc length of the second semicircle or semi-ellipse, and displays in addition to zoom in or out with respect to the enlarged or reduced first screen.

For example, the command for enlarging the screen using a circular or elliptical gesture of the user detects a clockwise semicircle or semi-ellipse gesture of the user and enlarges the first screen in proportion to the radius of the clockwise semicircle or semi-ellipse of the user. Display and determine whether the remaining second semi-circle or semi-ellipse gesture corresponding to the first semi-circle or semi-ellipse is detected in the clockwise direction, and the remaining second semi-circle or semi-ellipse gestures of the first semi-circle or semi-ellipse are When detected, the enlarged first screen is further enlarged and displayed according to the arc length of the remaining second semicircle or ellipse, and the remaining second semicircle or semi-ellipse gesture of the first semicircle or semi-ellipse is not detected in the clockwise direction. When not, i.e., when another second semicircle or second semi-ellipse gesture is detected in the counterclockwise direction, according to the arc length of the other second semicircle or ellipse, And it displays the reduced first screen.

For example, a command for screen reduction using a circular or elliptical gesture of a user detects a user's anticlockwise semicircle or semi-ellipse gesture and is proportional to the radius of the long axis or short axis of the user's counterclockwise semicircle or semi-ellipse. To reduce and display the second screen, determine whether the remaining second semi-circle or semi-ellipse gesture of the first semi-circle or semi-ellipse is detected in the counterclockwise direction, and the remaining second of the first semi-circle or semi-ellipse in the counterclockwise direction. When a semi-circle or semi-ellipse gesture is detected, the enlarged first screen is further enlarged and displayed according to the arc length of the remaining second semi-circle or ellipse, and the first semi-circle or the remaining second semi-circles of the semi-ellipse clockwise. When a semi-ellipse gesture is not detected, i.e., when another second semi-circle or second semi-ellipse gesture is detected in a clockwise direction, an arc of another second semi-circle or ellipse is detected.

Referring to FIG. 3, the electronic device detects a user's first semi-circle or semi-ellipse gesture in operation 300 (see FIGS. 6 (a) to 6 (b) and 7 (a) to 7 (b)). In step 302, the gesture input determines whether the gesture corresponds to a first semi-circle or semi-ellipse type gesture. When the detected first semi-circle or semi-ellipse becomes a gesture in a clockwise direction, the flow proceeds to step 304; Proceed to step.

In operation 304, the electronic device enlarges and displays the first screen in proportion to the detected radius of the first semicircle or the radius of the long axis or short axis of the semi-ellipse (FIGS. 6 (a) to 6 (b)). In the step, the first screen is reduced and displayed in proportion to the sensed radius of the first semicircle or the radius of the long axis or short axis of the semi-ellipse (and FIGS. 7A to 7B).

In operation 308, the electronic device determines whether a second semi-circle or semi-ellipse gesture is detected by the user. The second semi-circle or semi-ellipse gesture is a semi-circle or semi-ellipse gesture in a clockwise or counter-clockwise direction connected to at least one of two points of the first semi-circle or semi-ellipse. When the second semi-circle or semi-ellipse gesture is reached, the process proceeds to step 310, otherwise the procedure of the present invention is terminated.

In operation 310, the electronic device further enlarges or reduces the display of the enlarged or reduced first screen according to the length of the arc of the second semi-circle or semi-ellipse.

4 is a flowchart illustrating a screen enlargement using a circular or elliptical gesture of a user according to an exemplary embodiment of the present invention.

Referring to FIG. 4, in operation 400, the user determines a point to enlarge, and in step 402, performs a semicircle or semi-ellipse gesture in a clockwise direction at a separation distance corresponding to an enlargement ratio from the center of the point to be enlarged. Perform.

In operation 404, the electronic device detects a clockwise semi-circle or semi-ellipse gesture of the user, and enlarges and displays the first screen in proportion to the radius of the clockwise semi-circle or semi-ellipse of the user. That is, the larger the radius of the semi-circle or semi-ellipse is, the larger the enlargement ratio becomes. On the contrary, the smaller the radius of the semi-circle or semi-ellipse is, the lower the enlargement ratio is.

In operation 408, the electronic device determines whether the remaining second semi-circle or semi-ellipse gesture corresponding to the first semi-circle or semi-ellipse is detected in the clockwise direction. That is, it is determined whether to further enlarge or reduce the first screen enlarged in proportion to the radius of the long axis or short axis of the user's clockwise semicircle or semi-ellipse (see FIG. 8).

When the electronic device detects the remaining second semi-circle or semi-ellipse gesture of the first semi-circle or semi-ellipse in a clockwise direction, the electronic device proceeds to step 410 and adds an enlarged first screen according to the arc length of the remaining second semi-circle or ellipse. Zoom in to display.

On the other hand, when the electronic device does not detect the remaining second semi-circle or semi-ellipse gesture of the first semi-circle or semi-ellipse in the clockwise direction, that is, when another second semi-circle or second semi-elliptic gesture is detected in the counter-clockwise direction, In operation 412, the enlarged first screen is reduced and displayed according to the arc length of another second semi-circle or ellipse.

The procedure of the present invention is then terminated.

5 is a flowchart illustrating a screen reduction using a circular or elliptical gesture of a user according to an exemplary embodiment of the present invention.

Referring to FIG. 5, in operation 500, the user determines a point to reduce, and in step 502, a semi-circle or semi-ellipse gesture is anticlockwise at a separation distance corresponding to a reduction ratio from the center of the point to be reduced. Perform

In operation 504, the electronic device detects a user's counterclockwise semicircle or semi-ellipse gesture, and in step 506, the electronic device reduces and displays the second screen in proportion to the radius of the user's counterclockwise semicircle or semi-ellipse. In other words, as the radius of the semi-circle or semi-ellipse increases, the reduction ratio increases. On the contrary, as the radius of the semi-circle or semi-ellipse decreases, the reduction ratio decreases.

In operation 508, the electronic device determines whether the remaining second semi-circle or semi-ellipse gesture of the first semi-circle or semi-ellipse is detected in the counterclockwise direction. That is, it is determined whether to further enlarge or reduce the first screen reduced in proportion to the radius of the user's counterclockwise semicircle or semi-ellipse (see FIG. 9).

When the electronic device detects the remaining second semi-circle or semi-ellipse gesture of the first semi-circle or semi-ellipse in the counterclockwise direction, the electronic device proceeds to step 510 and displays the enlarged first screen according to the arc length of the second semi-circle or ellipse. Further enlarged display.

On the other hand, when the electronic device detects no second semi-circle or semi-ellipse gesture of the first semi-circle or semi-ellipse in the clockwise direction, that is, when another second semi-circle or second semi-ellipse gesture is detected in the clockwise direction, 512. In step S, the reduced first screen is enlarged and displayed according to the arc length of another second semi-circle or ellipse.

The procedure of the present invention is then terminated.

6 (a) to 6 (b) illustrate examples of screen enlargement using a circular or elliptical gesture action of a user according to an embodiment of the present invention.

Referring to FIG. 6A, when a user of an electronic device tries to enlarge a face of a subject present in an image, a gesture operation corresponding to an operation of drawing a clockwise concentric circle around a point to which the user wants to enlarge is performed. . In this case, as shown in FIG. 6B, the screen is enlarged and displayed. 6 (b) shows an effect of expanding the screen by a certain magnification around the subject face by a clockwise concentric gesture operation.

On the other hand, when the user moves clockwise in the form of concentric circles from the initial gesture point of view, when the point of semi-circle or semi-ellipse is reached, the actual zoom in effect occurs. Depending on the implementation, the point in time at which the actual zoom in effect occurs may be the point in time of reaching a point in the form of a circle or ellipse that is larger or smaller than half the shape of the circle or ellipse.

Also, the magnification at the time of reaching the semi-circle or semi-ellipse and the initial screen enlargement effect is proportional to the radius of the semi-circle or semi-ellipse, and the distance moved when the user gesture is maintained from the moment passing the arc length of the semi-circle or semi-ellipse Increase magnification in real time in proportion to. In this case, the enlargement magnification increased with respect to the additional gesture movement distance may increase linearly or may increase nonlinearly by a preset equation.

On the other hand, the screen magnification effect is enlarged based on the center point of the semi-circle or semi-ellipse, so that the user of the electronic device decides a point to be enlarged and the user wants to enlarge from the point (ie, the center point of the point to be enlarged). Start the gesture at the separation distance corresponding to the magnification and draw the concentric circles clockwise.

On the other hand, if you want to increase the electronic document (image, web page, etc.) size magnification beyond the arc length of the semi-circle or semi-ellipse, and you want to decrease the electronic document size magnification while moving further clockwise, you can hold the gesture half Move clockwise to get the effect of zooming out. This is possible by continuously observing the progress direction of the gesture in the electronic device internal processing device. The reduction ratio when the screen is reduced may be linearly reduced with respect to the distance moving in the counterclockwise direction similarly to the operation when the screen is enlarged, or may be nonlinearly reduced by a preset equation.

7 (a) to 7 (b) illustrate examples of screen reduction using a circular or elliptical gesture of a user according to an embodiment of the present invention.

Referring to FIG. 7A, when a user of an electronic device attempts to reduce the face of a subject existing in an image, a gesture corresponding to an operation of drawing a concentric circle in a counterclockwise direction with respect to a point where the user wants to reduce the screen is shown. Perform the action. In this case, as shown in FIG. 7B, the screen is reduced and displayed. FIG. 7 (b) shows the effect of reducing the magnification by a certain magnification around the subject's face by the counterclockwise concentric gesture operation.

On the other hand, when the user first reaches the point of the semi-circle or semi-ellipse in the counterclockwise direction in the form of concentric circles from the first gesture, the actual screen reduction effect occurs. Depending on the implementation, the point in time at which the actual zoom out effect occurs may be the point in time of reaching a point in the form of a circle or ellipse that is larger or smaller than half the form of a circle or ellipse.

In addition, when the half or half ellipse is reached and the initial screen reduction effect occurs, the scaling factor is proportional to the radius of the half circle or the half ellipse, and the user gesture is maintained from the moment passing the arc length of the half circle or the half ellipse. The electronic document size magnification can be reduced in real time in inverse proportion to the travel distance. In this case, the magnification of the electronic document size relative to the additional gesture movement distance may be linearly reduced or may be nonlinearly reduced by a preset equation.

On the other hand, as shown in Figure 6 (a), to further reduce the electronic document (image, web page, etc.) size magnification beyond the semi-circle or semi-ellipse point, while moving further in the counterclockwise direction electronic document size magnification If you want to increase, move clockwise while holding the gesture to get the effect of magnification. This is possible by continuously observing the progress direction of the gesture in the electronic device internal processing device. When the screen is enlarged, the electronic document enlargement ratio may increase linearly with respect to the clockwise movement distance or may increase nonlinearly by a preset equation.

8 illustrates a circle or ellipse gesture for controlling screen magnification according to an embodiment of the present invention.

Referring to FIG. 8, when the user executes a screen enlargement, after determining the initial gesture point 804 of the separation distance 802 corresponding to the enlargement ratio from the center 800 of the point to be enlarged, the initial gesture point ( At 804, a semicircle or semi-ellipse 806 is drawn in a clockwise direction to enlarge the screen. Subsequently, when the enlarged screen is further enlarged or reduced, the gesture is kept moving in the clockwise direction while maintaining the gesture (808) or the counterclockwise movement (810).

9 illustrates a circle or ellipse gesture for controlling screen reduction according to an embodiment of the present invention.

Referring to FIG. 9, when the user performs screen reduction, after determining the initial gesture point 904 of the separation distance 902 corresponding to the reduction ratio from the center 900 of the point to be reduced, the initial gesture point ( In 904, a semicircle or semi-ellipse 906 is drawn in the counterclockwise direction to enlarge the screen. Subsequently, when the enlarged screen is to be further enlarged or reduced, the gesture is kept moving in the counterclockwise direction (908) or clockwise (910).

FIG. 10 (a) illustrates an example of moving on the touch screen in a clockwise direction to perform screen magnification while having the same center of concentric circles but varying the radius of the concentric circles according to an embodiment of the present invention. For example, when the first concentric circle having the radius R2 is the first gesture coordinate (10,50) and reaches the gesture coordinate 60,50 while drawing the concentric circle, the concentric center coordinates 35,50 are determined. The electronic document is enlarged by a ratio corresponding to the value 25 of the radius R2 based on the coordinates. If the user continues the additional gesture, the size magnification of the electronic document is increased by reflecting the additional gesture moving distance in real time. A well-known heuristic algorithm can be used to drive the scaling algorithm of the present invention only when the user moves from gesture coordinates (10,50) to (60,50) in a concentric or elliptical state. In other words, if the pattern in which the user moves within a predetermined time after the initial gesture start is determined as the linear motion, the scrolling operation of the electronic document is performed instead of scaling. On the other hand, the second concentric circles having a radius (R1) is, for example, the gesture coordinates (20,50), if the gesture coordinates (50,50) is reached while drawing the concentric circles concentric coordinates (35,50) is obtained, The electronic document is enlarged by a ratio corresponding to the value 15 of the radius R1 based on the coordinates.

Likewise, in the case of performing the screen reduction by moving in the counterclockwise direction as in the embodiment of the screen enlargement situation through FIG. 10A, the same method is followed.

FIG. 10 (b) illustrates an example of moving on the touch screen in a counterclockwise direction to perform screen reduction while having the same center of concentric circles but varying the radius of the concentric circles according to an embodiment of the present invention.

FIG. 11A is a flowchart illustrating screen expansion using a circular or elliptical gesture as a screen display control method in an electronic device according to another embodiment of the present disclosure.

First, a gesture input detection process of detecting whether a gesture is input to an electronic device is performed (1110). Here, the gesture means that the touch screen of the electronic device is touched by an external input such as a finger or a stylus pen, and a drag is formed while the touch is maintained to form a pattern of a certain shape. The detection of the touch of the touch screen is made by the touch recognition method or other known method described through this specification.

Next, it is determined whether the gesture corresponds to a semi-circle or semi-elliptic gesture (1120). This includes a case in which the gesture substantially forms a semi-circle or semi-ellipse. Even if the shape of the semi-ellipse is slightly distorted, if the radius of the major axis of the semi-ellipse can be recognized, it is regarded as a semi-ellipse.

Next, when the gesture input is a semi-circle or semi-elliptic pattern, the touch screen screen is enlarged or reduced in proportion to the radius of the semi-circle or the radius of the long axis or short axis of the semi-ellipse (1130). Herein, when the touch screen screen is enlarged or reduced in proportion to the radius of the semicircle or the radius of the long axis or short axis of the semi-ellipse, the ratio of the screen enlargement or reduction is proportional to the radius. In other words, when the radius of the semicircle or the major or short axis of the semi-ellipse is large, it means that the ratio of screen enlargement or reduction is increased. Here, the ratio of the radius of the semicircle or the radius of the major axis or the minor axis of the semi-ellipse may be determined in advance and the ratio of screen enlargement or reduction.

On the contrary, when the radius of the semicircle or the long axis or short axis of the semi-ellipse is small, it is also possible to determine that the ratio of screen enlargement or reduction is larger. Alternatively, the rate of reduction can be predetermined.

In addition, when the gesture input is in the first direction, the touch screen screen is enlarged, and in the second direction, the touch screen screen is reduced.

FIG. 11B illustrates a device diagram for expanding a screen using a circular or elliptical gesture as a screen display control method in an electronic device according to another embodiment of the present disclosure.

First, the gesture input detecting unit 1140 detects whether a gesture is input to the electronic device (1140). Here, the gesture means that the touch screen of the electronic device is touched by an external input such as a finger or a stylus pen, and a drag is formed while the touch is maintained to form a pattern of a certain shape. The manner in which the gesture input sensing unit senses the touch of the touch screen is performed by the touch recognition method or other known method described through the present specification.

Next, the gesture type determining unit 1150 determines whether the input gesture corresponds to a semi-circle or semi-elliptic gesture. This includes a case in which the gesture substantially forms a semi-circle or semi-ellipse. Even if the shape of the semi-ellipse is slightly distorted, if the radius of the major axis of the semi-ellipse can be recognized, it is regarded as a semi-ellipse.

Next, when the gesture input is a semi-circle or semi-elliptic pattern, the display performing means 1160 enlarges or reduces the touch screen screen on the touch screen in proportion to the radius of the semi-circle or the radius of the long or short axis of the semi-ellipse. Perform the display process. The display performing means may be the controller 200 of the electronic device of FIG. 2 or the application processor 202 in the controller. Herein, when the touch screen screen is enlarged or reduced in proportion to the radius of the semicircle or the radius of the long axis or short axis of the semi-ellipse, the ratio of the screen enlargement or reduction is proportional to the radius. In other words, when the radius of the semicircle or the major or short axis of the semi-ellipse is large, it means that the ratio of screen enlargement or reduction is increased. Here, the ratio of the radius of the semicircle or the radius of the major axis or the minor axis of the semi-ellipse may be determined in advance and the ratio of screen enlargement or reduction. In addition, if the radius of the semicircle or the long axis or short axis of the semi-circle is small, the display performing means 1160 may determine that the ratio of screen enlargement or reduction is large, and the radius of the semicircle or the long axis or shortening of the semi-ellipse is large. The ratio of the size to the size of the screen enlargement or reduction can be preset. The display performing means 1160 may enlarge the touch screen screen when the gesture input is in the first direction, and reduce the touch screen screen when the gesture input is in the second direction.
