Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.

First, the proximity sensor 141 refers to a sensor that detects the presence of an object approaching a predetermined detection surface, or the presence of an object in the vicinity of the detection surface, without mechanical contact by using electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in the inner area of the mobile terminal or in proximity to the touch screen, which is covered by the touch screen.

Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is electrostatic, the proximity sensor 141 can be configured to detect the proximity of the object with a change of the electric field along the proximity of the object having conductivity. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of explanation, the act of recognizing that the object is located on the touch screen in proximity with no object touching the touch screen is referred to as "proximity touch & The act of actually touching an object on the screen is called a "contact touch. &Quot; The position at which the object is closely touched on the touch screen means a position where the object corresponds to the touch screen vertically when the object is touched. The proximity sensor 141 can detect a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, have. Meanwhile, the control unit 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern sensed through the proximity sensor 141 as described above, and further provides visual information corresponding to the processed data It can be output on the touch screen. Furthermore, the control unit 180 can control the mobile terminal 100 such that different operations or data (or information) are processed according to whether the touch to the same point on the touch screen is a proximity touch or a touch touch .

The touch sensor uses a touch (or touch input) applied to the touch screen (or the display unit 151) by using at least one of various touch methods such as a resistance film type, a capacitive type, an infrared type, an ultrasonic type, Detection.

For example, the touch sensor may be configured to convert a change in a pressure applied to a specific portion of the touch screen or a capacitance generated in a specific portion to an electrical input signal. The touch sensor may be configured to detect a position, an area, a pressure at the time of touch, a capacitance at the time of touch, and the like where a touch object touching the touch screen is touched on the touch sensor. Here, the touch object may be a finger, a touch pen, a stylus pen, a pointer, or the like as an object to which a touch is applied to the touch sensor.

Thus, when 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 transmits the corresponding data to the controller 180. Thus, the control unit 180 can know which area of the display unit 151 is touched or the like. Here, the touch controller may be a separate component from the control unit 180, and may be the control unit 180 itself.

On the other hand, the control unit 180 may perform different controls or perform the same control according to the type of the touch object touching the touch screen (or a touch key provided on the touch screen). Whether to perform different controls or to perform the same control according to the type of the touch object may be determined according to the current state of the mobile terminal 100 or an application program being executed.

Touch can be sensed.

The ultrasonic sensor can recognize the position information of the object to be sensed by using ultrasonic waves. Meanwhile, the controller 180 can calculate the position of the wave generating source through the information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the fact that the light is much faster than the ultrasonic wave, that is, the time when the light reaches the optical sensor is much faster than the time the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generating source can be calculated using the time difference with the time when the ultrasonic wave reaches the reference signal.

The camera 121 includes at least one of a camera sensor (for example, a CCD, a CMOS, etc.), a photo sensor (or an image sensor), and a laser sensor.

The camera 121 and the laser sensor may be combined with each other to sense a touch of the sensing object with respect to the three-dimensional stereoscopic image. The photosensor can be laminated to the display element, which is adapted to scan the movement of the object to be detected proximate to the touch screen. More specifically, the photosensor mounts photo diodes and TRs (Transistors) in a row / column and scans the contents loaded on the photosensor using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor performs coordinate calculation of the object to be sensed according to the amount of change of light, and position information of the object to be sensed can be obtained through the calculation.

The mobile terminal 100 (see FIG. IA) according to an embodiment of the present invention, which can include at least one of the above-described components, can perform a video image shooting function. The image photographing function may mean a function of storing an image received through the camera 121 (see FIG. 1A) in the memory 170 (see FIG. 1A). Here, the operation of the mobile terminal storing the image received through the camera 121 in the memory 170 may include 'capture images',' capture images', 'capture images',' Perform image shooting operation ', and the like. In addition, various expressions having the meaning of storing the image received through the camera 121 in the memory 170 can be freely used without being bound to the above-mentioned expressions.

Execution of the image photographing function may mean executing an application which is driven for image photographing. When the image capturing function is executed, the control unit 180 can activate the camera 121 to prepare the image capturing state.

 The image photographing function can be executed based on whether the icon (or the icon of the application) associated with the image photographing function is selected (or touched). On the basis of the icon being selected, when the image photographing function is performed, the display unit 151 may be on. Meanwhile, the image capturing function may include at least one of a key (e.g., at least one of a hardware key and a software key) included in the mobile terminal, in addition to the method of selecting the icon associated with the image capturing function , It can be executed. In this case, even if the display unit 151 is off, the control unit 180 can execute the image photographing function corresponding to the selection of the key included in the mobile terminal.

The mobile terminal according to the present invention can perform a video image capturing operation based on a user's selection, and the selection of such a user can be expressed by a 'user control command' or a 'control command'. For example, when a user touches or presses a hardware key provided on the mobile terminal, or when a software key (for example, the user can perform a video photographing operation by touching a key or a visual key. That is, the control unit 180 (see FIG. 1A) of the mobile terminal 100 displays a software key or a visual key (see FIG. 1A), which is displayed on the display unit 151, visual key) is touched, it can be determined that the user's control command for performing the image photographing operation has been received.

Also, the present invention is not limited to this, and the mobile terminal 100 related to the present invention can photograph images based on reception of user control commands in various manners. For example, when the image received (input) through the camera 121 is output on the display unit 151, the control unit 180 controls the image or the touch of the predetermined type in the display unit 151 It is possible to shoot the image based on the addition.

The predetermined type of touch is a touch associated with the image capturing operation, and may include various types of touches. For example, the preset touch may be a short touch, a continuous touch, a long touch, a multi touch, or the like, in which at least two short touches are applied within a reference time, Touch, drag, touch, flick touch, pinch-in touch, pinch-out touch, swype touch, hovering touch And the like.

In addition, the mobile terminal 100 related to the present invention may capture the image (or the graphic object) based on whether the graphic object (or the image corresponding to the subject) included in the image satisfies predetermined conditions . For example, when it is determined that the graphic object included in the image is more similar to the pre-stored graphic object than the threshold, the controller 180 may capture the image (or the graphic object).

The image received through the camera 121 may be referred to as a preview image and refers to an image received through the camera 121 in real time. That is, the image (or the screen information included in the image) received through the camera 121 may be information indicating that the mobile terminal 100 is moved by an external force and that the object (or the object) existing within the angle of view of the camera 121 And the like).

The image (or the preview image) may be stored in the memory unit 170 as either a still image or a moving image.

Meanwhile, the mobile terminal 100 related to the present invention can perform the iris recognition function.

An iris scan refers to a technique or an authentication system for recognizing a person using iris information of an eye having unique characteristics for each person. That is, the iris recognition function may refer to a function of recognizing the user using the iris information of the eye or a function of authenticating the user. In the present specification, terms such as iris recognition, iris recognition, iris authentication, and iris authentication are used interchangeably, and they can be accepted in the same or similar meaning.

The human iris has characteristics that do not change forever after it is completed after about 18 months of age. That is, the circular iris pattern that is raised near the inner side of the iris (the concert) hardly changes once it is determined, and the shapes are different from person to person.

The iris recognition function refers to the function of informing the characteristics of iris, which is different for each person, and applying it as an authentication technology for security. For example, the iris recognition function may be a function of encoding an iris pattern using an iris image into an iris code, and performing user authentication by comparing the iris pattern with a previously stored iris code in a memory or an external server An iris recognition algorithm for encoding an iris pattern into an iris code, and a method for performing user authentication by comparing iris codes are general techniques, and thus a detailed description thereof will be omitted).

Various types of cameras may be used for performing the iris recognition function. For example, a camera using an infrared ray (or an infrared camera) may be used. The camera 121 described below is an infrared camera as an example.

In the iris recognition function, the above-described image photographing function can be used. Specifically, the iris recognition function may include an iris registration step and an iris recognition step. The image capturing function using the camera 121 may be used in each of the iris registration step and the iris recognition step.

In the iris registration step, the information related to the iris of the user (for example, an image related to iris, an image corresponding to iris (iris image), iris code, (Registered) on the Internet. The information related to the iris stored in the iris registration step serves as a comparison object when the iris recognition step is performed later.

Specifically, the controller 180 may perform the iris registration step based on the user request. The user request may include: executing an application associated with the iris recognition function; and receiving a user control command for entering the iris registration step in the application (e.g., an icon for entering the iris registration step is selected and an iris registration step A touch of a predetermined type in association with a function of entering the touch screen), and the like may be input.

Upon entering the iris registration step, the control unit 180 can activate the camera (for example, the infrared camera) 121. In addition, the control unit 180 can photograph the received image (or the image corresponding to the eye) when an image corresponding to the user's eye (eyeball) is identified in the image received through the camera. The photographed image may be stored in the memory 170 and an external terminal (or an external server).

The control unit 180 can identify an image corresponding to the user's eyes included in the image and extract an image (iris image) related to the iris from the image corresponding to the eye.

Thereafter, the controller 180 encodes the iris pattern of the user into an iris code using an image (iris image) related to the iris, and transmits at least one of the iris related image and the iris code to the memory 170 and the external terminal (Or an external server).

Thereafter, the control unit 180 may perform the iris recognition step based on the user's request. The user request may include at least one of: an execution of an application associated with the iris recognition function by the user; a user control command (e.g., an icon to enter the iris recognition step; A touch of a predetermined type in association with a function of entering the iris recognition step), and the like may be input.

Upon entering the iris recognition step, the control unit 180 can activate a camera (for example, an infrared camera) 121. In addition, when the image corresponding to the user's eye (eyeball) is identified in the image received through the camera 121, the control unit 180 can extract an image related to the iris from the image corresponding to the eye. Thereafter, the controller 180 generates an iris code using the image related to the iris, and determines whether the iris code matches the iris code previously stored in the memory, thereby performing user authentication.

In this case, extraction of the image related to the iris, generation of the iris code, and the like may be performed after the image received in the iris recognition step is captured, or may be performed after the image is received through the camera (For example, a state in which a preview image is output to the display unit 151).

Meanwhile, the mobile terminal 100 related to the present invention can provide various UI / UX that can increase the user authentication rate (or the iris recognition rate) through the iris recognition as described above. Hereinafter, a method for increasing a user authentication rate through iris recognition in the present invention will be described in more detail with reference to the accompanying drawings. Hereinafter, the iris registration step of the iris recognition function described above will be mainly described.

FIG. 2 is a flowchart illustrating an exemplary control method of the present invention, and FIG. 3 is a conceptual diagram illustrating a control method illustrated in FIG. 2. Referring to FIG.

In the present invention, by storing a plurality of iris-related information (for example, an iris-related image, an iris code, and the like) to be compared with each other in performing iris recognition, images corresponding to the iris received in the iris recognition step The authentication rate can be improved by performing iris recognition (or user authentication) using information related to a plurality of previously stored irises.

2, in order to acquire information related to the plurality of different irises (or images related to a plurality of different irises), in the present invention, an image received through a camera is displayed on a part of a display region of the display unit The display step is advanced (S210). Specifically, when an image is received through the camera 121 (for example, a camera using an infrared ray (infrared camera)), the control unit 180 displays at least a part of the image in a part of the display area of the display unit 151 Can be displayed.

Referring to FIG. 3, the display area A of the display unit 151 may have a size corresponding to the size of the display unit 151. Here, all the screen information that can be output from the mobile terminal related to the present invention can be displayed in the display area A of the display unit 151.

The control unit 180 activates the camera 121 and displays the image 300 received through the camera 121 on the display area 151 of the display unit 151 Can be displayed in a part of the area R1 of the display area A. [ The camera 121 may be disposed together with the display unit 151 on the front surface of the main body of the mobile terminal, as shown in FIG.

The partial area R1 may be at least a part of the display area A of the display part 151. In the display area A of the display part 151, Information can be displayed. For example, no screen information is displayed in the remaining area, guide information for guiding iris registration, icons, indicators, graphic objects, and buttons associated with various functions related to the iris recognition function may be displayed.

The size of the partial region R1 in which the image 300 received through the camera 121 is displayed may be determined by the user's setting or the size of the image 300. [ In addition, the size of the image 300 (or the size of the partial region R1) may be changed by a control command of the user. For example, if a dragging touch is applied starting from the edge of the image 300 (or a partial region R1), the controller 180 may change the size of the image 300 based on the dragging touch have. Alternatively, the control unit 180 may reduce the size of the image 300 based on whether the pinch-in touch is applied to the image 300 (or a partial region R1) The size of the image 300 can be enlarged.

The present invention displays the image 300 received through the camera 121 only in a partial region R1 of the display region A of the display unit 151 so that the user can see his or her eye , It is possible to more accurately capture the image related to the iris required for iris registration.

Also, although not shown, the controller 180 may display (or overlap) a graphic object (e.g., an eye image) on the image 300 that guides the user's eye-fitting position have.

Referring back to FIG. 2, in the present invention, the step of outputting the image to an area different from the area in which the image is output at the time of photographing is performed based on the image being photographed such that different images related to the iris are captured (S220).

Specifically, when the image of the image displayed on a part of the area of the display unit 151 is photographed so as to photograph an image related to a plurality of irises, the control unit 180 controls the iris And output the image.

For example, as shown in the first and second drawings of FIG. 3, the control unit 180 determines whether the image 300 received through the camera 121 is displayed in the display area A of the display unit 151 When the image 300 is photographed in a state in which the partial region R1 is displayed, the image 300 can be displayed in the region R2 different from the partial region R1. The other region R2 may overlap or at least partially overlap with the region R1 (or the partial region R1) from which the image 300 is output at the time of photographing.

Specifically, when the image 300 is photographed in the state that the image 300 is output to the first region R1, the control unit 180 may convert the image 300 into the first region R1 To the second region R2 different from the first region R2. Here, outputting an image to a second area different from the first area may include the meaning of 'moving an image' or 'changing an output position of an image'.

At this time, the output size of the image 300 can be kept constant even if the region (or position) from which the image 300 is output is changed. The control unit 180 controls the display unit 151 such that the image 300 displayed in the partial region R1 of the display region A is captured, The image 300 can be displayed in the region R2 different from the partial region R1.

The first image 310a related to the iris is photographed while the image 300 is displayed on the first region R1 and the image 300 is displayed on the second region R2 different from the first region R1 The second image 310b related to the iris different from the first image can be photographed as the user's line of sight is changed.

Here, the image related to the iris may include an image corresponding to the user's eye, an image corresponding to the iris included in the user's eye (or an iris image), and the like.

The photographing of the image related to the iris is performed by taking an image related to the iris and then generating / storing information (for example, iris code) related to the iris through the iris recognition algorithm using the image related to the iris . ≪ / RTI >

The shooting of the image may be performed a predetermined number of times. At this time, the control unit 180 can change the display position of the image every time the image is photographed. The predetermined number of times may be determined by the control of the user or the control unit.

According to the present invention, in the present invention, by changing the display position of the image received through the camera when capturing an image related to the iris, it is possible to induce the user's gaze to be changed. As a result, You can shoot. In addition, according to the present invention, different images related to the iris are captured and stored, so that the state of images related to the iris included in the image received through the camera according to the iris recognition, the surrounding environment, The iris recognition rate (or the user authentication rate) can be significantly improved by performing iris recognition (or user authentication) using different images related to the iris.

Hereinafter, a method of displaying an image received through a camera in a part of a display area of the display unit will be described in more detail with reference to the accompanying drawings.

Here, the image received through the camera displayed on the partial area may be the entire image received through the camera 121, or may be at least a part of the image.

4A, the control unit 180 displays an image 410 corresponding to a part of all the images 400 received through the camera in a part of the display region of the display unit 151 (for example, R1a). A part of the entire image 400 may be predefined by user setting. For example, as shown in the first diagram of FIG. 4A, a center part 400 having a predetermined size among the whole images 400 .

4B, the control unit 180 may display the entire image 400 received through the camera in a partial area R1b of the display area of the display unit 151. [

As another example, as shown in FIG. 4C, the control unit 180 may extract at least one region including an image corresponding to the user's eyes among all the images 400 received through the camera. The control unit 180 may track at least one area including an image corresponding to the user's eyes even if the terminal is moved by an external force or the screen information included in the image is changed according to a user's movement.

The images 420a and 420b corresponding to the at least one region may include an image corresponding to the user's eyes (or an image related to the iris).

Then, the controller 180 extracts any one of the images 420a and 420b corresponding to at least one region including the image corresponding to the user's eyes (for example, 420b) (420b) can be displayed in a partial area (R1c) of the display area of the display unit (151).

(Not shown) is displayed on the display unit 151 in a state where at least a part of the images received through the camera is displayed in a part of the display area of the display unit 151, Image) can be displayed. The guide information can be displayed at various positions, for example, in a remaining area of the display area of the display unit 151 other than the partial area in which the image is displayed.

In addition, the mobile terminal related to the present invention can display at least a part of the images received through the camera in a part of the display area of the display part 151 by various methods.

With this configuration, the present invention can provide a user interface that can display an image received through a camera in various ways in a part of the display area of the display unit 151. [

Referring to FIG. 5, FIG. 5 is a conceptual diagram illustrating an interface associated with the iris recognition function according to the present invention.

As shown in FIG. 5, the mobile terminal according to the present invention can display the screen information related to the iris recognition function on the display unit 151 when the iris recognition function is executed. As described above, at least a part of the images received through the camera may be displayed on a part of the display area of the display unit 151. [ In addition, the controller 180 may include various functions related to the iris recognition function, for example, an icon 510 associated with a function for entering the iris registration step, and an icon 520 associated with a function for entering the iris recognition step Can be displayed.

When the icon 510 associated with the function of entering the iris registration step is selected, a function of photographing different images related to the iris can be performed. When the icon 520 associated with the function of entering the iris recognition step is selected, an image related to the new iris is received using the image received through the camera, Iris recognition can be performed using different images related to the previously stored iris (the method of performing iris recognition in the iris recognition step is a general technique, so a detailed description will be omitted).

Hereinafter, a method of photographing different images related to an iris to be compared at the time of iris recognition according to the present invention will be described in more detail with reference to the accompanying drawings.

6A, 6B, and 7 are conceptual diagrams for explaining a method for acquiring different images related to iris.

6A, as shown in the first drawing of FIG. 6A, the control unit 180 can enter the iris registration step to photograph and register different images related to the iris. The control unit 180 may output the image 300 received through the camera 121 to a partial region R6a of the display region of the display unit 151. In this case, Here, the image displayed in the partial area R6a may be an image according to any one of the schemes described in FIGS. 4A to 4C.

Thereafter, the control unit 180 may photograph the image 600 output to the partial region R6a in various ways in order to capture (or store, acquire, etc.) the image related to the iris. For example, the control unit 180 may photograph the image 600 based on recognition of an image related to the iris in the image 600. The photographing of the image 600 means that photographing the image 600 itself output to the display unit 151 and that at least a part of the image 600 (e.g., an image related to the iris) Taking a picture, and the like.

As described above, the image related to the iris may include an image corresponding to the user's eye, an image corresponding to the iris included in the user's eye (or an iris image), and the like.

Specifically, when the image related to the user's iris (or an image corresponding to the eyes) is output to the image 600 received through the camera, the control unit 180 can recognize the image. The control unit 180 can recognize images related to the iris in various manners. For example, the controller 180 can recognize an image related to the iris using an image analysis function for the image.

For example, a template corresponding to an eye (or a template corresponding to an iris) may be stored in the memory unit 170, and the controller 180 may store the template corresponding to the previously stored eye ) And the image related to the iris included in the image received through the camera coincide with each other by a predetermined threshold value or more, an image related to the iris can be recognized.

The control unit 180 can perform the photographing of the image 600 based on the recognition of the image related to the iris in the image 600. [ After capturing the image 600, the controller 180 extracts a portion corresponding to the iris by using an image related to the iris included in the image 600, and extracts information related to the iris using the extracted portion, (E. G., An iris code). ≪ / RTI >

Meanwhile, the control unit 180 may perform image capturing on the image based on the output of the image related to the iris being maintained for a preset time while the image related to the iris is output to the image. Specifically, the control unit 180 determines that the motion (or change) of the image 610a related to the iris is not detected for a preset time while the image 610a related to the iris is output to the image 600 The image 600 can be photographed.

6A, guide information 650 for guiding an image related to the iris to be output to the image, and a guide information 650 for guiding the output of the image related to the iris to a predetermined time Information 660 for guiding the information to be maintained for a certain period of time may be displayed.

When the photographing of the image 600 received through the camera is performed in the first area R6a corresponding to a part of the display area of the display unit 151, The image 600 can be output to the second region R6b different from the first region R6a as shown in FIG. As the image 600 is displayed in the second area R6b different from the first area R6a, the user's line of sight may be changed, and accordingly, the image 600 displayed in the second area R6b may be changed. The image 610b related to the iris included in the first region R6a may be different from the image 610a related to the iris included in the image displayed in the first region R6a.

6A, when the image 600 is displayed on the second region R6b, the controller 180 recognizes that the image 610b related to the iris in the image 600 is recognized And the output of the image 610b related to the iris is maintained for a preset time.

FIG. 6A illustrates that four photographing operations are performed. At this time, each photographing can be performed when the image 600 is outputted to different areas R6a, R6b, R6c, and R6d as shown in FIG. 6A. Further, each photographing can be performed on the basis of satisfaction of the condition as described above.

Accordingly, the control unit 180 can capture (or store, acquire) different images 610a, 610b, 610c, and 610d related to the iris. Further, the controller 180 generates information (for example, iris code) related to the iris for each image using the different images 610a, 610b, 610c, and 610d related to the iris, Information related to the iris may be used in the iris authentication.

On the other hand, the control unit 180 can photograph an image received through the camera based on a control command of the user.

For example, as shown in FIG. 6B, in a state in which an image 600 received through a camera is outputted to a partial area 610a of a display area of the display unit 151, the image 600 (Or the display unit 151) to which the predetermined touch is applied.

Here, the predetermined type of touch is a touch associated with the image capturing operation for the image 600, and may include various types of touches. For example, the preset touch may be a short touch, a continuous touch, a long touch, a multi touch, or the like, in which at least two short touches are applied within a reference time, Touch, drag, touch, flick touch, pinch-in touch, pinch-out touch, swype touch, hovering touch And the like.

As another example, the display unit 151 may display an icon 620a (or a button, a key, a graphic object, and the like) associated with the image photographing operation on the image. In this case, the control unit 180 can photograph the image 600 based on the touch of the icon 620a.

At this time, the control unit 180 may perform photographing of the image 600, assuming that the image 600 related to the iris is recognized in the image 600. Specifically, the control unit 180 determines whether a predetermined type of touch is applied to the image 600 or the icon 620a is displayed in a state in which the image 610a related to the iris is recognized in the image 600, The image 600 can be photographed based on the touch.

That is, even if a predetermined type of touch is applied to the image 600 or a touch is applied to the icon 620a, the control unit 180 determines that the image 610a related to the iris is not recognized in the image 600 State, the photographing may not be performed.

In this case, when the image 600 related to the iris is recognized in the image 600, the control unit 180 can output notification information that can guide the recognition. The notification information may be in the form of sound, vibration, text, graphic objects, icons, and the like. When the icon 620a is output to the display unit 151, the controller 180 outputs the icon 620a as a disabled state in which the response to the touch input is limited before the recognition, The icon 620a may be changed to an active state in which a response to the touch input is possible.

6B, when the image 600 is photographed, the control unit 180 controls the image 600 to be displayed on the area 600 where the image 600 is output R6a and the other region R6b. In a state in which the image 600 is output to the other region R6b, the control unit 180 can photograph the image 600 based on the reception of the user control command as described above.

6B, the controller 180 may include an indicator 612 (or a progress bar) for guiding the number of times the image 600 is photographed, And a thumbnail (or photographed image) 614 for the captured image can be output to the display unit 151. The indicator 612 and the thumbnail 614 may be displayed on at least a part of the display area of the display unit 151. For example, Can be output to the remaining area except for the area.

6A and 6B are not limited to the respective embodiments, but may be implemented through at least two combinations.

On the other hand, the control unit 180 may change the display mode of the image if the image displayed on a part of the display area of the display unit 151 is photographed.

7, the image 700 received through the camera 121 in some areas of the display area of the display unit 151 is output as a first output size S1, 7, the control unit 180 controls the image 700 so that the first output size S1 is different from the first output size S1, 2 output size (S2).

Likewise, when the image of the image 700 having the second output size S2 is performed, the controller 180 controls the image 700 to be displayed on the display screen 2 output size S2 and a third output size S3 different from the output size S2.

For example, the first to third output sizes S1 to S3 may become larger as shown in FIG.

When the output size of the image 700 is changed, at least one of the amount of light projected onto the user's eye and the focal length is changed, so that the shape of the user's eye (or iris shape, pupil shape, etc.) .

Accordingly, the controller 180 can obtain different images 710a, 710b, and 710c related to the iris by changing the output size of the image 700. FIG. For example, as shown in FIG. 7, as the size of the image 700 displayed on the display unit 151 increases, the amount of light projected onto the user's eye increases, so that the pupil of the eye becomes smaller . Accordingly, since the shape of the iris is also changed, the image related to the iris included in the image 700 can be changed.

According to the present invention, different images related to the iris can be obtained by changing the size of the image displayed in a part of the display area of the display unit.

In the meantime, in the present invention, when the shooting of the image fails, various user interfaces that can induce the shooting success can be provided.

Hereinafter, with reference to the accompanying drawings, various examples of a case where shooting of an image fails and a control method in this case will be described in more detail.

FIGS. 8A and 8B are conceptual diagrams for explaining a method of inducing the photographing of an image related to an iris when an image related to the iris is not photographed. FIG.

As described above, according to the present invention, when an image related to an iris is recognized from an image received through a camera, if the output of the image is maintained for a preset time, The image including the image related to the iris may be photographed based on at least one of a case in which a touch is applied and a case in which an icon associated with the image photographing operation for the image is touched.

The control unit 180 outputs the image 800 received through the camera 121 to a partial region R8 of the display region of the display unit 151 and displays the image 800 related to the iris 810a are recognized, it is possible not to photograph the image 800 if the predetermined condition is satisfied.

For example, when the mobile terminal moves, when the image related to the iris included in the image moves (or changes), the color included in the image is changed A case where the color corresponds to a preset color, and the like.

For example, as shown in the first drawing of FIG. 8A, the control unit 180 displays the image 810a related to the iris in the image 800 displayed in the partial area R8 of the display area of the display unit 151 Even if it is recognized, if it is detected that the body of the mobile terminal is moving, the photographing may not be performed. In this case, in a state in which the output position of the image 800 is maintained, the control unit 180 controls the information to notify that the photographing has failed and the movement of the terminal / To the display unit 151, the notification information 850 including at least one of information to be displayed on the display unit 151.

8B, when the image 810b related to the iris recognized in the image 800 corresponds to a preset condition, the control unit 180 performs imaging with respect to the image 800 It is possible to output the image 800 to another area.

For example, as shown in the first diagram of FIG. 8B, the preset condition is that when the brightness of at least a portion 820 of the image 810b associated with the iris included in the image 800 is greater than the reference brightness Lt; / RTI > Specifically, when the user wears glasses or the like, light blurring (or light reflection or the like) occurs due to the glass provided in the glasses, and at least part of the images 810b related to the iris included in the image 800 May be greater than the reference brightness.

Here, at least a part of the image 810b related to the iris may mean an image portion corresponding to a pupil or iris. That is, when at least a part of the image 810b related to the iris corresponds to the light bleeding portion 820, the brightness of the at least a part may be larger than the reference brightness.

In this case, the control unit 180 may output the image 800 to the region R8b different from the region R8a, instead of performing the photographing of the image 800. [ In this case, as the position at which the image 800 is output is changed, the user moves the terminal or performs an operation of changing the posture. Thus, at least some of the image 810b associated with the iris (e.g., the portion of the image corresponding to the pupil or iris) and the light bleed portion 820, as shown in the second diagram of Figure 8b, So that the brightness of at least a part of the image 810b associated with the iris becomes smaller than the reference brightness (i.e., a portion where light blurring (or light reflection) occurs deviates from the image portion corresponding to the pupil or iris) .

When the brightness of at least a part 820 of the image 810b related to the iris is larger than the reference brightness, the controller 180 changes the display position of the image 800, (860) to the display unit (151).

8B, in the present invention, when the brightness of at least a part of the image 810b associated with the iris becomes smaller than the reference brightness (i.e., the at least a portion and the light bleeding portion 820 do not coincide , The control unit 180 may perform image capturing for the image and acquire an image related to the iris.

With this configuration, in the present invention, it is possible to provide a user interface capable of photographing or acquiring an image related to the iris in an optimized state even if the surrounding environment is changed. 8A and 8B can be applied not only to the iris registration step but also to the iris recognition step for performing iris recognition.

As described above, the present invention can capture a plurality of images related to the iris used for iris recognition, and the images related to the plurality of irises can be different from each other. Accordingly, the present invention can improve the recognition rate of iris recognition by performing iris recognition using images related to different iris.

In addition, the present invention can provide a UI / UX capable of shooting images related to the different irises in an optimized manner.

The present invention described above can be embodied as computer-readable codes on a medium on which a program is recorded. The computer readable medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of the computer readable medium include a hard disk drive (HDD), a solid state disk (SSD), a silicon disk drive (SDD), a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, , And may also be implemented in the form of a carrier wave (e.g., transmission over the Internet). Also, the computer may include a control unit 180 of the terminal. Accordingly, the above description should not be construed in a limiting sense in all respects and should be considered illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the scope of equivalents of the present invention are included in the scope of the present invention.
