5 is a flowchart schematically showing a device driving method according to an embodiment of the present invention. Hereinafter, the contents explained with reference to Figs. 1 to 4 will be omitted.

Referring to FIG. 5, a device 100 according to an embodiment of the present invention may perform a step of displaying a visual symbol (step S401). In this case, the visual symbol may be input through the input unit 110 of the device 100 or may be generated from the signal received from the external device 200 or the server 300 through the communication unit 140 of the device 100 It may be something. The step S401 may be performed by the display unit 120 of the device 100. [

Then, the device 100 may perform the step of controlling the display unit 120 so that at least a part of the visual symbols displayed on the display unit 120 are blurred (S402). At this time, the device 100 may cause all of the visual symbols displayed on the display unit 120 to be blurred, and only some visual symbols may be blurred. The step S402 may be performed by the control unit 130 of the device 100. [

Then, the device 100 may perform the step of detecting the input to the first position (step S403). Here, the first position may be a position where the blurred visual symbols are displayed, or a position corresponding to the blurred visual symbols. Alternatively, the first position may be a predetermined position on the display unit 120. [ Alternatively, the first position may be a position where a particular button or sensor on the device 100 is present. The step S403 may be performed by the input unit 110 of the device 100. [

Thereafter, the device 100 may perform the step of checking whether the detected input is the same as the first operation (step S404). Here, the first operation may be a touch operation of a tap for a predetermined position, a double tap for a predetermined position, a long tap for a predetermined position, and a tap-after-tapping operation. Alternatively, the first operation may be an operation of pressing a predetermined physical button or an operation of holding the physical button pressed for a predetermined period or more. Alternatively, the first operation may be fingerprint sensing, body temperature sensing, pressure sensing, operation of contacting a portion of the body or a predetermined instrument with a predetermined level of electrical flow sensing device. Alternatively, the first operation may be an air gesture taken on a predetermined position, without physical contact. The step S404 may be performed by the control unit 130 of the device 100. [

If the detected input is inconsistent with the first operation, the device 100 may revert back to before step S403 to detect the input to the first position. That is, the device 100 may be in a standby state until it receives an input to the first location, or may switch or maintain a state in which it can receive another input.

If the detected input matches the first action, the device 100 may perform the step of releasing some of the blurs applied to the visual symbols (step S405). At this time, the device 100 may control the display unit 120 to release the blur applied to at least some of the visual symbols corresponding to the first of the visual symbols. Optionally, the device 100 may also control the display 120 to release the blur of visual symbols across the display 120 of the device 100 when a first action is detected for a predetermined position have. The step S405 may be performed by the control unit 130 of the device 100. [

Alternatively, after step S405, the controller 130 of the device 100 may further perform the step of measuring the elapsed time after the blur applied to at least some of the visual symbols has been released. In this case, the control unit 130 of the device 100 may control the display unit 120 such that at least some of the visual symbols are blurred when the elapsed time reaches the first time. That is, when the user takes the first operation at the first position, the device 100 releases some blur and applies the blur again after a predetermined time elapses.

Alternatively, after step S405, the control unit 130 of the device 100 may measure the elapsed time from any one of the moment when the input to the first position is started and the moment when the input to the first position is finished You can do more. In this case, the control unit 130 of the device 100 may control the display unit 120 so that at least some of the visual symbols are blurred when the elapsed time reaches the second time. That is, when the user keeps inputting to the first position (for example, when the user touches a position where a specific visual symbol is displayed and keeps the corresponding touch state) The blur can be applied again after a certain period of time has elapsed from the moment when the user has left the finger (i.e., the moment the user removes the finger). In this case, when the user of the device 100 holds the touch, the state where the continuous blur is released is maintained, and when the touch is released, the blur can be applied after a predetermined time elapses. Through this, the device 100 can provide the effect of varying the period in which the blur is released according to the convenience of the user of the device 100.

Optionally, when visual symbols are displayed in step S401, the control unit 130 of the device 100 may display the visual symbols on the display 100 such that at least some of the visual symbols on the way to the device 100 are blurred as soon as they are input, Lt; RTI ID = 0.0 > 120 < / RTI > Specifically, the control unit 130 of the device 100 determines whether the user of the device 100 is in the middle of proceeding with the current input (for example, while the user is writing text to send to the external user, Text created until the call is made) can also be controlled so that the display unit 120 is blurred. Through this, the device 100 can provide the effect of keeping the privacy of the visual symbol currently being input by the user of the device 100 as well.

Optionally, the control unit 130 of the device 100 may select one of the visual symbols on the way to the input of the device 100, the visual symbols whose time elapsed since the input is less than the third time, The visual symbols of at least one of the visual symbols within the first distance in at least one of the up, down, left, and right directions at the position where the at least one visual symbol is disposed may be blurred. In general, when a user of the device 100 inputs a text, it is most likely to directly confirm the content that the user has just entered before correcting errors in the typo or contents. Thus, if the blur is applied immediately when the user enters a visual symbol into the device 100, the user may not be able to verify that he or she has correctly entered the content. Accordingly, the device 100 can control the display unit 120 so that the visual symbols after a predetermined time, i.e., the third time period, are not blurred. Or, in general, the user of device 100 may move to the middle of the visual symbols he / she has entered and modify the content. Accordingly, the device 100 can control the display unit 120 so that the visual symbols near the position where the input cursor is disposed are not blurred. For example, when the user moves the cursor between the word 'today' and the word 'lunch' while inputting the sentence 'what to eat for lunch today', the device 100 is called 'today' and 'lunch' You can make sure the word blur is not applied and that the blur is applied to 'what to eat?' In this way, the device 100 can provide an opportunity to easily edit the visual symbol input by the user of the device 100.

Optionally, the communication unit 140 of the device 100 may further perform the step of receiving a data signal from the external device 200 before displaying the visual symbols in step S401. In this case, the device 100 can acquire a visual symbol from the received data and display it on the display unit 120 in step S401. That is, the device 100 receives not only the visual symbols created by the user of the device 100 but also the information including the information of the visual symbols created by the user (i.e., the external user) of the external device 100, The display section 120 can display the visual symbols created by the user.

Optionally, the control unit 130 of the device 100 may cause the visual symbol obtained from the data signal received through the communication unit 140 to be blurred after a third time period has elapsed after being displayed on the display unit 120 The display unit 120 may be controlled. That is, when a user of the device 100 communicates with an external user of the external device 200 through a chat service or the like, the device 100 may display the visual symbol created by the external user in the device 100, So that the user of the device 100 can recognize the contents. After that, the device 100 can protect the privacy by allowing the visual symbol created by the external user to be blurred when a predetermined time has elapsed.

Alternatively, the control unit 130 of the device 100 may display a predetermined number of visual symbols in the order of the latest displayed time on the display unit 120 among the visual symbols obtained from the data signal received through the communication unit 140 It is possible to perform the step of controlling the display unit 120 so as not to be blurred. That is, when a user of the device 100 communicates with an external user of the external device 200 through a chat service or the like, the device 100 prevents the visual symbols recently created by the external user from being blurred, The user of the device 100 can recognize the content. The device 100 may then blur existing visual symbols when new visual symbols are displayed on the display 120.

Optionally, the controller 130 of the device 100 may perform the step of controlling the display 120 to release at least some of the blur applied to the display 120 when scrolling occurs on the display 120 have. That is, if the user of the device 100 has a large number of visual symbols to perform scrolling, the user can perform scrolling to confirm the visual symbols received or input in the past. In this case, since the user of the device 100 must not apply blur in order to find a past visual symbol, the control unit 130 of the device 100 controls the display unit 120 to release the blur of the display unit 120 . The controller 130 of the device 100 may selectively display the display unit 120 so that at least a part of the blur applied to the display unit 120 is released only when the display unit 120 scrolls at a predetermined first speed or more Control. That is, since the slow scrolling may not be an operation for the user of the device 100 to find a specific visual symbol, the device 100 may display only the scroll symbol, which is applied to the display unit 120 only when scrolling occurs above a predetermined first speed The display unit 120 may be controlled so that at least a part of the blur is released.

Optionally, the controller 130 of the device 100 may also perform a step of controlling the blur mode to one of an on state or an off state. If the blur mode is on, the device 100 can apply the blur processing method of the visual symbol described with reference to Fig. On the other hand, when the blur mode is off, the device 100 may omit blur processing of at least some of the visual symbols. Through this, the device 100 can provide the user of the device 100 with the ability to prevent or apply blur to visual symbols, such as the need to be kept private.

Optionally, the control unit 130 of the device 100 recognizes the state of the device 100 itself or the environment around the device 100, and controls the blur mode to be in an on state or an off state Can be performed. Specifically, the control unit 130 of the device 100 may determine the on / off state of the blur mode directly from the user of the device 100. [ However, even when the on / off state of the blur mode is not directly determined, the device 100 can adjust the blur mode according to the surrounding environment. For example, the device 100 may include a sensor for detecting shaking. In this case, the device 100 judges how much the device 100 is shaken. If the device 100 has a lot of shaking, the device 100 determines that the user of the device 100 is in the public, and turns the blur mode on If the device 100 has a small amount of blur, it is determined that the user of the device 100 is in a private space, and the blur mode can be changed to the off state. Conversely, the device 100 may change the blur mode to the off state when the device 100 has a lot of shaking, and may change the blur mode to on when the device 100 has little shaking. In another example, the device 100 may include a sensor for detecting whether or not a sound is generated. In this case, the device 100 determines how loud the periphery of the device 100 is. If the noise around the device 100 is present at a certain level or more, the device 100 determines that the user of the device 100 is in the public The blur mode can be changed to the on state, and when the device 100 is quiet, the blur mode can be changed to the off state by determining that the user of the device 100 is in the private space. Conversely, the device 100 may change the blur mode to off when the device 100 is noisy and change the blur mode to on when the device 100 is noisy. In another example, the device 100 may determine the on / off state of the blur mode based on whether an electronic signal of a first intensity or greater is being received from the external device 200. [ At this time, the electronic signal of the first intensity or higher may be a signal for short-range communication such as a Bluetooth signal, a near field communication (NFC) communication signal, or the like. That is, when the device 100 receives a close-range communication signal of a first strength or higher from the external device 200, the device 100 determines that there are other electronic devices around the device 100, 100) is in the public. Thus, in this case, the device 100 may change the blur mode to the on state. If the device 100 does not receive a local communication signal of a first intensity or higher, the device 100 may determine that the user of the device 100 is in a private space and may change the blur mode to the off state . Conversely, the device 100 may change the blur mode to an off state when an electronic signal of a first intensity or more is received, and change the blur mode to on state when an electronic signal of a first intensity or more is not received.

Alternatively, the device 100 may send the blur only when at least one of fingerprint recognition of the user, eye recognition of the user, and password input is performed through the input unit 110 or the communication unit 140 of the device 100 Apply blur, turn blur off, or turn blur mode on / off. That is, since the privacy protection of the user of the device 100 is one of the reasons for blurring, the device 100 may undergo various authentication processes from the user for controlling the blurring state.

Alternatively, the device 100 can recognize the shape of the eyeball of the user or the surrounding person by using an image pickup element such as a camera included in the device 100, and can grasp the position where the line of sight is directed. In this case, the device 100 can release the blur when the user's gaze of the device 100 stays on the display unit 120 of the device 100, and the gaze of a person other than the user of the device 100 When staying on the display unit 120 of the device 100, the blur effect can be applied.

Optionally, the device 100 may selectively apply a first blur with a relatively strong blur degree and a second blur with a relatively weak blur degree to the visual symbols. Concretely, the visual symbol without blur processing can easily be recognized by the viewer. In addition, the weakly blurred visual symbol may be perceived when the visual symbol is concentrated, but may not be perceived when not focused. In addition, the visual symbols that are subjected to strong blur processing may not be recognized even when the visual symbols are concentrated. The device 100 may control the display unit 120 to apply the first blur to the visual symbols to which the blur is to be applied and apply the second blur to the visual symbols that need to be blurred. Alternatively, the device 100 may determine a blur to apply to the visual symbols, either as a first blur or a second blur, depending on the input from the user, the environment around the device 100, or the state of the device 100 itself have.

The device 100 may perform this using at least one of various image processing techniques when applying or releasing blur to visual symbols. At this time, the device 100 may apply or cancel the blur by applying an image processing mask or an image processing filter corresponding to at least one of various image processing techniques.

FIGS. 6 to 12 are views schematically showing an example of how a device is driven according to an embodiment of the present invention. Hereinafter, examples of blur application or blur release described above will be described with reference to Figs. 6 to 12. Fig.

Referring to FIG. 6, the display unit 120 of the device 100 may display visual symbols 601 indicating the content of the conversation between the user of the device 100 and the external user of the external device 200. FIG. In addition, a UI 602 of an application providing a visual dialog function can be displayed on the display unit 120 of the device 100 as well.

At this time, blur can be applied to only a part of the area of the display unit 120 of the device 100. [ 7, blur can be applied only to the visual symbols 701 indicating the contents of the conversation between the user of the device 100 and the external user of the external device 200, and the UI of the application providing the visual conversation function (702) may not be blurred. That is, since the visual symbols 701 representing the conversation contents must be maintained in privacy, the device 100 performs the blur processing on the visual symbols 701 indicating the conversation contents, and the UI of the application providing the visual conversation function Since the portion 702 of the application 702 is not related to the privacy of the user, the device 100 does not perform the blur processing on the UI 702 portion of the application providing the visual dialog function, .

8, the device 100 receives an input to select a particular visual symbol among the visual symbols 801 representing the content of conversation between the user of the device 100 and an external user of the external device 200 . For example, when a user touches a portion indicated by a visual symbol 'EFG' among visual symbols 801 indicating the contents of conversation between a user of the device 100 and an external user of the external device 200, the device 100 ) Can release the blur applied to the visual symbol 'EFG'. At this time, the device 100 can maintain the blur applied to the remaining area except the visual symbol 'EFG' without releasing it. In this case, the device 100 can maintain the state where the blur is not applied in the UI (802) portion of the application providing the visual dialogue function.

9, the device 100 may display a UI 903 for switching blur application on the display unit 120. [ When the user of the device 100 touches the UI 903 for switching blurring application, the device 100 displays visual symbols representing the content of the conversation between the user of the device 100 and the external user of the external device 200 It is possible to apply the blur to the entire image 901 or to release the applied blur. Even in this case, the device 100 can maintain a state in which the UI 902 portion of the application providing the visual dialogue function is not blurred.

10, the device 100 determines whether or not blur processing of the visual symbols 1001 in the middle of inputting to the device 100 is performed on the display unit 120, It can be determined separately from visual symbols. That is, the device 100 may not apply the blur to the visual symbols 1001 in the middle of the input, even if the visual symbols of the other area of the display unit 120 are all blurred.

11, the device 100 may display a layer for displaying a visual symbol on the display unit 120 and a layer for displaying a space in which a visual symbol can be displayed. For example, as shown in FIG. 11 (a), the device 100 displays a visual symbol called " conversation contents ", and a visual symbol indicating a two parallelogram shape surrounding the visual symbol It is possible to display a layer for indicating a space that can be used. At this time, the device 100 can perform a blur processing operation only on a part of the layers. For example, as shown in FIG. 11 (b), the device 100 performs a blurring process on a layer in which visual symbols such as 'conversation contents' are displayed, so that the visual symbols 'conversation contents' Can be changed. At this time, the device 100 may omit blur processing for the layer for indicating the space where the visual symbol can be displayed. Accordingly, the device 100 can apply blur only to a necessary area, thereby reducing the hardware resource consumption required for blur processing while maintaining a visually clean effect.

On the other hand, referring to FIG. 12, when device 100 performs blur processing, it may perform blur processing on visual symbols whose resolution is lower than the original visual symbol. Specifically, the device 100 can change the visual symbol having the size as shown in Fig. 12 (a) to a visual symbol having the size as shown in Fig. 12 (b). That is, the device 100 may generate a first temporary visual symbol by reducing the resolution of the visual symbols to which the blur is to be applied. Thereafter, the device 100 may blur the first temporary visual symbol as shown in Figure 12 (c) to generate a second temporary visual symbol. Thereafter, the device 100 may enlarge the second temporary visual symbol, as shown in Figure 12 (d), to generate the visual symbol for which the blur processing is complete. In general, when applying blur to an image, it may be necessary to apply a relatively large image processing mask or apply a complex image processing filter. As a result, hardware resource consumption for blur processing can be very large when the visual symbol itself for applying blur is high in resolution. Accordingly, the device 100 can reduce the amount of computation generated in the blur application process by using a method of switching the resolution of visual symbols as shown in FIG.
