For example, in the mobile terminal 100, a plurality of display portions may be spaced apart from one another, or may be disposed integrally with one another, and may be disposed on different surfaces, respectively.

When the display screen 163 and a sensor for detecting a touch motion (hereinafter, referred to as a touch sensor) form a mutual layer structure (hereinafter, referred to as a touch screen), the display screen 163 is an output device. It can also be used as an input device. The touch sensor may have the form of, for example, a touch film, a touch sheet, a touch pad, or the like.

The touch sensor may be configured to convert a change in pressure applied to a specific portion of the display screen 163 or capacitance generated at a specific portion of the display screen 163 into an electrical input signal. The touch sensor may be configured to detect not only the position and area of the touch but also the pressure and directionality of the touch.

If there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and then transmits the corresponding data to the controller 190. As a result, the controller 190 may determine which area of the display screen 163 is touched.

Detailed description thereof will be made with reference to FIGS. 3 and 4.

The power supply unit 210 receives an external power source and an internal power source under the control of the controller 190 to supply power for operation of each component.

The shake detection unit 220 detects a shake of the mobile communication terminal 100. In other words, the shake detection unit 220 may detect a shake of the mobile communication terminal 100 by using the preview image captured by the camera.

The drag detector 230 detects a drag of the display screen 163. That is, the drag detector 230 may detect a drag start point and a drag end point by detecting a drag point when the user drags the display screen.

The shake detection unit 220 and the drag detection unit 230 will be described in more detail with reference to FIGS. 3 and 4.

A text voice conversion method in a mobile communication terminal will be described with reference to FIGS. 3 and 4.

According to the present invention, when the terminal shakes due to an external influence in a specific place, the terminal detects the shaking of the terminal and converts the text sprayed through the display screen of the terminal into a voice, so that the user can easily recognize the text on the display screen. have. This will be more clearly understood through the description of FIGS. 3 and 4 below.

Therefore, according to the present invention, even when the user is watching a specific content through the display screen in a severe shaking environment (for example, in a bus where the shaking is heavy), the screen shake phenomenon (that is, the output image due to the shaking of the terminal). This blurring phenomenon can minimize eye strain.

However, in FIG. 3 to be described below, a method of detecting the shaking of the terminal according to the present invention will be described as an example of detecting the shaking of the terminal through analysis of a preview image input through a camera mounted on the terminal. have. However, as a premise for implementing the text voice conversion method (hereinafter, referred to as a text voice conversion method) according to the present invention, a method different from that of FIG. 3 may be used as a method for detecting the shaking of the terminal.

That is, in order to detect the shaking of the terminal, in addition to the method of analyzing the preview image using the camera, various sensors mounted in the terminal (for example, shaking detection sensors such as geomagnetic sensors, acceleration sensors, motion sensors, etc.) It may be easily understood by those skilled in the art that the shaking of the terminal may be detected without a specific description.

In addition, although the flowchart of FIG. 3 is illustrated as performing a text voice conversion without setting a separate mode and entering, it will be described later only when there is a confirmation as to whether to enter the text voice conversion mode as required or set. It is obvious that text voice conversion may be performed. In this case, the entry into the text voice conversion mode may be based on a clear intention of the user (for example, a key input, a touch input, a specific motion detection, a voice input, etc.). It may be set to automatically enter when the terminal shaking continues over a certain reference value.

Here, although the shaking reference value and / or the shaking duration time and the shaking reference value as the reference for actually performing the screen shake correction, which will be described later, may be set in advance in the terminal. Obviously, it may be set or updated according to the selection of. In addition, the shaking reference value, which is a reference for automatic entry into the text voice conversion mode, and the shaking reference value, which is a reference for determining whether to actually execute the text voice conversion, may have the same value or may be set to have different values. For example, the latter may be set to have a larger value than the former.

3 is a flowchart illustrating a text voice conversion method according to an embodiment of the present invention, and FIG. 4 is an exemplary view illustrating a text voice conversion method according to an embodiment of the present invention.

Referring to FIG. 3, the shake detection unit 220 detects a shake of the mobile communication terminal 100 (310). Specifically, the controller 190 controls the camera 135 to turn on the camera 135. In this case, the turn-on time of the camera 135 may be the same time as the entry time into the text voice conversion mode. The preview image input through the camera 135 may be stored in the memory unit 170. In this case, the preview image input through the camera 135 is not displayed through the display screen 163 and is stored in the memory unit 170 and thus is used only as basic information for detecting future shaking.

When the preview image is stored in the memory unit 170 every frame, the shake detection unit 220 may obtain information about the shake of the mobile communication terminal 100 based on the change of the preview image. For example, the shake detection unit 220 compares the previous and subsequent preview images input through the camera 135 whenever the preview images are sequentially stored in the memory unit 170 for each frame. We can calculate the shaking degree (displacement) or the shaking speed of.

When the shake information of the mobile communication terminal 100 is obtained from the shake detection unit 220, the controller 190 checks whether the shake information of the mobile communication terminal 100 is equal to or greater than a preset shake reference value (320). At this time, the shaking reference value may be set or updated by the user. That is, the user can set the degree to which the mobile voice terminal 100 starts to shake the text voice conversion. In addition, the shaking reference value may be set in advance to the extent of screen shaking at a critical time point at which a person feels eye fatigue based on the statistical result.

Meanwhile, if the shaking degree of the mobile communication terminal 100 is less than the shaking reference value, the controller 190 controls the display screen 163 to continue displaying text through the display screen 163 (330). At this time, the display screen 163 displays text.

If the shaking degree of the mobile communication terminal 100 is greater than the shaking reference value, the drag detector 230 detects a drag of the display screen 163 (340). That is, when the user drags any point of the displayed text through the display screen 163, the drag detector 230 detects the point dragged by the user and creates a drag start point and a drag end point.

For example, when the user drags the display screen 163 as shown in FIG. 4A, the drag detector 230 starts a drag point on the user interface screen 410 of the display screen 163. The drag start point 415 may be generated by determining whether the drag start point 415 is generated, and the drag end point may be generated by determining the drag end point. In this case, the drag detector 230 may indicate a drag start point and a drag end point as coordinate values.

The shake detection unit 220 detects a shake of the mobile communication terminal 100 (350). Since the description of detecting the shake has been described in operation 310, a detailed description thereof will be omitted.

The controller 190 checks whether the shaking degree is equal to or greater than the conversion reference value in the dragged state (360). In this case, the conversion reference value is a reference value for the shaking of the mobile communication terminal 100 for converting the text into the voice and may be set by input from a user or through a preset algorithm (for example, a program or a probability model). have.

On the other hand, if the shaking degree of the mobile communication terminal 100 is less than the conversion reference value, the controller 190 controls the display screen 163 to continue to display the text on the display screen 163 (370). That is, the display screen 163 displays text.

If the shaking degree of the mobile communication terminal 100 is equal to or greater than the conversion reference value in the dragged state, the controller 190 converts the text displayed on the display screen 163 to voice (380). In other words, the controller 190 converts the text into voice according to the conversion setting. In this case, the conversion setting is a setting of which part of the text is converted into a voice and may be set by receiving an input from a user. The transformation setting may be one of a full transformation, a drag partial transformation, and a post-drag transformation. That is, when the conversion setting is the entire conversion, the controller 190 may convert the entire text displayed on the display screen 163 into the voice.

In addition, when the conversion setting is the drag partial conversion, the controller 190 determines text corresponding to the drag start point and the drag end point detected by the drag detection unit 230 among the texts displayed on the display screen 163. And converts the determined text into a voice.

When the conversion setting is conversion after dragging, the controller 190 determines text displayed after the drag start point or the drag end point detected by the drag detector 230 among the texts displayed through the display screen 163, Convert the judged text to voice.

Since a technique for converting text to voice is apparent to those skilled in the art, a detailed description thereof will be omitted.

Text voice conversion method according to an embodiment of the present invention is implemented in the form of program instructions that can be executed by various computer means may be recorded on a computer readable medium. Computer-readable media may include, alone or in combination with the program instructions, data files, data structures, and the like.

The program instructions recorded on the computer readable medium may be those specially designed and constructed for the present invention, or may be known and available to those skilled in the computer software arts.
