2 is a diagram illustrating a screen including a touch sensor configured according to an exemplary embodiment of the present invention.

Referring to FIG. 2, the device of the present invention includes a touch pad device 200 in which a plurality of touch sensors are densely distributed on a screen, and a method 210 of operating the sensor by touching the screen.

The touch pad 202 of the portable terminal includes a plurality of touch sensors 204. Many touch sensors are distributed to detect the touch of the entire screen densely on the screen to detect the touch where the user wants to focus.

The operation method 210 of the touch sensor will be described by enlarging one touch sensor 204. When the user touches the screen as shown in FIG. 210 to select the focus, the touch sensor is operated by pressure to check the sensing amount. The touch sensor checks the sensing amount of the sensor so that the zoom in / out function of the desired focus is executed.

FIG. 3 is a diagram illustrating a screen for focusing an image displayed on a display unit of a portable terminal by specifying an area.

Referring to FIG. 3, FIG. 3A sets an area where a start point and an end point meet while touching a plurality of touch sensors 301 included in the touch screen unit to focus a displayed point on a displayed image. This is the screen.

FIG. 3 (b) is a screen in which the focus is adjusted to a point set by the user, and a method of focusing by designating an area will be described later with reference to FIG. 4.

4 is a flowchart illustrating a flow of photographing using zoom in / out of a portable terminal using a touch sensor constructed according to an embodiment of the present invention.

Referring to FIG. 4, in step 401, it is determined whether a camera shooting search event occurs. If the shooting search event does not occur in step 401, the portable terminal proceeds to step 403 and waits for step 401 to check whether a shooting search event occurs.

If the shooting search event occurs in step 401, the portable terminal proceeds to step 405 and outputs an image to be shot on the screen, and then the portable terminal proceeds to step 407 to detect a touch of the screen.

As a result of the check in step 407, if no touch is detected, the portable terminal proceeds to step 425 and checks whether a picture is taken. As a result of the inspection in step 425, when the photographing signal is received, the portable terminal terminates the present algorithm by capturing the photograph.

As a result of the check in step 407, if a touch is detected on the touch screen of the portable terminal, the portable terminal proceeds to step 409 to check the detection of the focus touch. In step 409, a user checks a sensing amount of a touch in order to set the focus of an image. The focus touch is a method for setting focus and sets an area where a start point and an end point meet while touching a screen. Say how.

If the check result of step 409 is not confirmed as the focus touch, the portable terminal proceeds to step 417 to check the detection of the zoom-in touch. The step 417 is a step of checking the detection amount of the touch to execute the zoom in. The zoom-in touch is a method for executing the zoom in. The user touches the screen at short intervals to zoom in. Repeats a short touch, the portable terminal includes a method of executing zoom in as many times as the number of repeated touches. If the check result of step 417 is confirmed as the zoom in touch, the portable terminal proceeds to step 419 to perform zoom in. If the check result of step 417 is confirmed as the zoom out touch, the portable terminal proceeds to step 421 to zoom out. Next, go to step 423 to output the zoom image. The zoom out touch of step 417 refers to a state in which the screen is touched at a predetermined time interval to zoom out the focus of the screen as a method for executing zoom in / out. The focus of the screen is zoomed out, and if the touch is repeated like the zoom in, the portable terminal zooms out as many times as the touch repeatedly. The zoom in / out method of the above step refers to a method of zooming in and zooming out at a predetermined predetermined ratio based on a point detected by a touch sensor of the touch screen unit.

If the result of the check in step 409 is confirmed as the focus touch, the portable terminal proceeds to step 411 to check the area, and the portable terminal proceeds to step 413 to perform focus adjustment.

The method of confirming the area of step 411 is a method of designating a location of a focus. A method of setting a region where a start point and an end point meet while the user touches a screen, and sets multiple focuses of an image displayed on a display unit. Includes the focus function.

When the focus adjustment is completed in step 413, the portable terminal proceeds to step 415 to output the focus image. The focus image of step 415 refers to an image to which focus adjustment is applied by setting an area where a user desires.

In step 413, the mobile terminal checks whether the image is taken. As a result of the inspection in step 423, when the photographing signal is received, the portable terminal photographs and ends the present algorithm. If the photographing signal is not received, the portable terminal proceeds to step 405 and outputs a photographed image.

5 is a flowchart illustrating a flow of checking a stored image of a portable terminal using a touch sensor configured according to an embodiment of the present invention using a zoom in / out function.

Referring to FIG. 5, it is determined whether an image search event occurs in step 501. As a result of the step 501 inspection, if the image search event does not occur, the portable terminal proceeds to step 503 and waits to step 501 to check whether an image search event occurs.

If an image search event occurs in step 501, the portable terminal proceeds to step 505 to output an image to be checked on the display unit and the portable terminal proceeds to step 507 to sense a touch of the screen. As a result of the check in step 507, if no touch is detected, the portable terminal terminates the present algorithm.

If a touch is detected on the screen as a result of step 507, the portable terminal proceeds to step 508 to confirm detection of a short touch.

The step 508 is a step of checking the detection amount of the touch to execute the zoom in / out, and the short touch is a method for executing the zoom in / out to touch the screen at short intervals to zoom in. When the user repeats a short touch, the portable terminal zooms in as many times as the repeated touch.

If a short touch is detected as a result of the check in step 508, the portable terminal proceeds to step 511 to zoom in on a portion to be enlarged of the picture output on the display unit. If it is detected, the portable terminal proceeds to step 513 to zoom out the focus. The long touch of the above method refers to a state in which the screen is touched at a predetermined time interval to zoom out the focus of the screen as a method of performing zoom in / out. After zooming out and repeating touches such as zoom in, the portable terminal zooms out as many times as repeatedly touched. The zoom in / out method of the above step refers to a method of zooming in and zooming out at a predetermined predetermined ratio based on a point detected by a touch sensor of the touch screen unit.

The portable terminal executes zoom in / out and proceeds to step 515 to output a new zoom image to which the zoom in / out function is applied and ends the present algorithm.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications may be made without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined not only by the scope of the following claims, but also by the equivalents of the claims.

As described above, in order to reduce the inconvenience of the existing methods for using the zoom in / out function of the portable terminal, the present invention relates to a method of quickly and accurately focusing by using a touch sensor. To give convenience.
