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 or absence of an object approaching a predetermined detection surface or an object existing in the vicinity using the force of an electromagnetic field or infrared rays without mechanical contact. In the proximity sensor 141, the proximity sensor 141 may be disposed in an inner area of the mobile terminal surrounded by the touch screen described above or near 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 type proximity sensor, a magnetic type proximity sensor, an infrared proximity sensor, and the like. When the touch screen is a capacitive type, the proximity sensor 141 may be configured to detect the proximity of the object by a change in the electric field according to the proximity of the conductive object. 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 action of allowing an object to be located on the touch screen without being in contact with the object to be recognized as being positioned on the touch screen is named "proximity touch", and the touch The act of actually touching an object on the screen is called "contact touch". A position at which an object is touched in proximity on the touch screen means a position at which the object is vertically corresponding to the touch screen when the object is touched in proximity. The proximity sensor 141 may detect a proximity touch and a proximity touch pattern (eg, a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, a proximity touch movement state, etc.). have. Meanwhile, as above, the controller 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern sensed through the proximity sensor 141, and further, provides visual information corresponding to the processed data.

Here, the touch object is an object that applies a touch to the touch sensor, and may be, for example, a finger, a touch pen, a stylus pen, or a pointer.

In this way, when there is a touch input to the touch sensor, the signal(s) corresponding thereto is transmitted to the touch controller. The touch controller processes the signal(s) and then transmits the corresponding data to the controller 180. Accordingly, the controller 180 can know which area of the display unit 151 has been touched. Here, the touch controller may be a separate component from the controller 180 or may be the controller 180 itself.

Meanwhile, the controller 180 may perform different controls or perform the same control according to the type of the touch object by touching the touch screen (or a touch key provided in addition to the touch screen).

The ultrasonic sensor may recognize location information of a sensing target by using ultrasonic waves. Meanwhile, the controller 180 may calculate the location of the wave generator through information sensed from the optical sensor and the plurality of ultrasonic sensors. The location of the wave generator may be calculated by using a property that the light is much faster than that of the ultrasonic wave, that is, the time that the light reaches the optical sensor is much faster than the time that the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generator may be calculated using a time difference between a time when the ultrasonic wave arrives using light as a reference signal.

The photosensor may be stacked on the display device, and the photosensor is configured to scan the motion of a sensing object close to the touch screen. More specifically, the photo sensor scans the contents placed on the photo sensor by mounting a photo diode and a transistor (TR) in a row/column and using an electrical signal that changes according to the amount of light applied to the photo diode. That is, the photosensor calculates the coordinates of the sensing object according to the amount of light change, and through this, position information of the sensing object may be obtained.

The mobile terminal 100 (refer to FIG. 1A) according to an embodiment of the present invention capable of including at least one of the above-described components may perform an image capturing function. The image capturing 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 to store the image received through the camera 121 in the memory 170 is'taking an image','acquiring an image','capturing an image', ' It may be expressed as'to perform an image capturing operation'. In addition, various expressions having a meaning of storing an image received through the camera 121 in the memory 170 may be freely used without being restricted to the expressions listed above.

Execution of an image capturing function may mean executing an application driven for capturing an image. When such an image capturing function is executed, the controller 180 may activate the camera 121 and prepare the image to be captured.

The image capturing function may be executed based on selection (or touch) of an icon (or an application icon) associated with the image capturing function. When an image capturing function is performed based on the selection of the icon, the display unit 151 may be in an on state. Meanwhile, in the image capturing function, in addition to the method of selecting an icon associated with the image capturing function, at least one key (eg, at least one of a hardware key and a software key) provided in the mobile terminal is selected. If so, it can be executed. In this case, even if the display unit 151 is in an off state, the controller 180 may execute an image capturing function in response to a key provided in the mobile terminal being selected.

The mobile terminal related to the present invention may perform an image capturing operation based on a user's selection, and the user's selection may be expressed as a'user's control command' or a'control command'. Meanwhile, the user's selection may be made in various ways. For example, the user touches or presses a hardware key provided in the mobile terminal, or a software key output on the display unit 151 (refer to FIG. 1A). By touching (key) or a visual key, an image capturing operation can be performed. That is, the controller 180 (refer to FIG. 1A) of the mobile terminal 100 may touch or press a hardware key associated with an image capturing function, or output to the display unit 151, a software key or a visual key ( When the visual key) is touched, it may be determined that a user's control command for performing an image capturing operation has been received.

Further, the present invention is not limited thereto, and the mobile terminal 100 according to the present invention may capture an image based on receiving various types of user control commands. For example, in a state in which an image received (input) through the camera 121 is output on the display unit 151, the control unit 180 may perform a preset type of touch on the image or the display unit 151. Based on what is applied, the image can be taken.

The preset type of touch is a touch associated with an image capturing operation, and may include various types of touch. For example, the preset type of touch is a short (or tap) touch, a continuous touch in which at least two short touches are applied within a reference time, a long touch, and a multi touch. , Drag touch, flick touch, pinch-in touch, pinch-out touch, swype touch, hovering touch Various types of touch may be included, such as.

In addition, the mobile terminal 100 related to the present invention may capture the image (or the graphic object) on the basis that the graphic object (or the image corresponding to the subject, etc.) included in the image satisfies a preset condition. I can. For example, when it is determined that the graphic object included in the image matches (or is similar to) a pre-stored graphic object by more than a threshold value, 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 screen information included in the image) received through the camera 121 is that the mobile terminal 100 is moved by an external force and an object (or subject) existing within the angle of view of the camera 121 ) Can be changed based on moving.

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

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

Iris scan refers to a technology or authentication system that recognizes a person using iris information of an eyeball that has unique characteristics for each person. That is, the iris recognition function may mean a function of recognizing or authenticating a user using iris information of an eyeball. In the present specification, terms such as iris recognition, iris recognition function, iris authentication, iris authentication function, and the like are used interchangeably, and these may be taken as the same/similar meanings to each other.

The human iris is completed after about 18 months of age and has a characteristic that does not change throughout life. In other words, the circular iris pattern raised near the inner side (pupil) of the iris hardly changes once it is determined, and the shape of each person is different.

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

Various types of cameras may be used to perform the iris recognition function, and as an example, an infrared camera (or infrared camera) may be used. The camera 121 to be described below will be described as an example of an infrared camera.

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

In the iris registration step, information related to the user's iris (eg, an image related to an iris, an image corresponding to the iris (iris image), an iris code, etc.) is stored in the memory 170 and an external terminal (or an external server). It means the step of storing (registration) in the etc. Information related to the iris stored in the iris registration step serves as a comparison target when the iris recognition step is performed later.

Specifically, the controller 180 may perform an iris registration step based on a user request. The user request is to execute an application related to the iris recognition function and a user control command for entering the iris registration step in the application (e.g., selecting an icon for entering the iris registration step and the iris registration step This may include inputting, for example, applying a preset type of touch associated with a function to enter into.

When entering the iris registration step, the controller 180 may activate a camera (eg, an infrared camera) 121. In addition, when an image corresponding to the user's eye (eye) is identified from the image received through the camera, the controller 180 may capture the received image (or an image corresponding to the eye). The captured image may be stored in the memory 170 and an external terminal (or external server).

The controller 180 may identify an image corresponding to the user's eye included in the image, and extract an image related to the iris (iris image) from the image corresponding to the eye.

Thereafter, the controller 180 codes the user's iris pattern into an iris code using an image related to the iris (iris image), and converts at least one of the image related to the iris and the iris code to the memory 170 and an external terminal. (Or, it can be stored in an external server).

Thereafter, the controller 180 may perform an iris recognition step based on a user request. The user request is that an application related to the iris recognition function is executed by the user, a user control command for entering the iris recognition step in the application (for example, an icon for entering the iris recognition step is selected, and This may include inputting, for example, applying a preset type of touch associated with a function of entering the iris recognition step.

When entering the iris recognition step, the controller 180 may activate a camera (eg, an infrared camera) 121. In addition, when an image corresponding to the user's eye (eye) is identified from the image received through the camera 121, the controller 180 may extract an image related to the iris from the image corresponding to the eye. Thereafter, the controller 180 may generate an iris code by using the image related to the iris, and may perform user authentication by determining whether it matches the iris code previously stored in the memory.

At this time, extracting the image related to the iris, generating the iris code, etc. may be performed after the image received in the iris recognition step is photographed, or the image is received through the camera without taking a separate image. It may be performed in a state (for example, a state in which a preview image is output on the display unit 151).

Meanwhile, the mobile terminal 100 related to the present invention may provide various UI/UXs capable of increasing a user authentication rate (or iris recognition rate) through 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. In addition, in the following, the iris registration step of the iris recognition functions described above will be mainly described.

FIG. 2 is a flowchart representatively showing a control method of the present invention, and FIG. 3 is a conceptual diagram illustrating the control method described in FIG. 2.

In the present invention, a plurality of information related to an iris to be compared in performing iris recognition (eg, an image related to an iris, an iris code, etc.) are stored differently, and a plurality of information related to the iris received in the iris recognition step are stored. By performing iris recognition (or user authentication) using previously stored information related to a plurality of different irises, the authentication rate may be improved.

Referring to FIG. 2, in order to acquire information related to a plurality of different irises (or images related to a plurality of different irises), in the present invention, a step of displaying an image received through a camera on the display unit is performed. (S210). Specifically, when an image is received through the camera 121 (eg, an infrared camera (infrared camera)), the controller 180 may display the image on the display unit 151.

In this case, as shown in FIG. 3, the controller 180 may display an image 300 received through the camera on some of the display areas A of the display unit 151. Here, the display area A of the display unit 151 may have a size corresponding to the size of the display unit 151. In addition, in the display area A of the display unit 151, all screen information that can be output from the mobile terminal related to the present invention may be displayed.

When the iris authentication function is executed (when the iris registration step is entered), the controller 180 activates the camera 121 and displays the image 300 received through the camera in the display area A of the display unit 151 It can be displayed in some of the areas R. 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 the first drawing of FIG. 3. Hereinafter, for convenience of description, the mobile terminal and the main body will be denoted by the same reference numeral 100.

The partial area R1 may be at least a part of the display area A of the display unit 151, and the remaining areas of the display area A of the display unit 151 excluding the partial area R1 include various screens. Information can be displayed. For example, no screen information may be displayed in the remaining area, guide information for guiding iris registration, icons, indicators, graphic objects, buttons, etc. to which various functions related to the iris recognition function are linked may be displayed.

In addition, the size of the partial region R1 in which the image 300 received through the camera 121 is displayed may be determined by a user's setting or according to 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 user's control command. For example, when a drag touch starting from the edge of the image 300 (or a partial region R1) is applied, the controller 180 can change the size of the image 300 based on the drag touch. have. As another example, the controller 180 reduces the size of the image 300 or applies a pinch-out touch based on the application of a pinch-in touch to the image 300 (or a partial region R1). Based on the loss, the size of the image 300 may be enlarged.

In the present invention, the image 300 received through the camera 121 is displayed only in a partial area R of the display area A of the display unit 151, so that the user selects his/her eyes (eyes) from the image 300. ), it is possible to more accurately capture an image related to the iris required for iris registration.

In addition, the controller 180 displays a guide image (or a graphic object guiding a position where the user's eyes are matched) to guide a position in which an image related to the iris is to be output, on the image 300 (or overlap). ) Can (see Figs. 8A and 8B). The guide image may include various types of images, such as an eye-shaped image and a circle-shaped image. The guide image may overlap a partial area of the image 300.

The controller 180 may capture the image 300 based on the correspondence between the guide image and the image 310 related to the iris included in the image 300 received through the camera 121. The related content will be described later in more detail with reference to FIGS. 8A and 8B.

Returning to FIG. 2 again, in the present invention, while the image related to the iris is displayed on the image, the step of photographing the image is performed based on the fact that the main body is inclined at a predetermined inclination (S220).

Specifically, the controller 180 tilts the main body 100 of the mobile terminal at a predetermined inclination while the image 310 related to the iris is displayed on the image 300 so as to capture an image related to a plurality of irises. Based on the loss, the image 300 may be photographed.

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).

In addition, capturing the image may include capturing an image related to the iris displayed in the image. In addition, capturing the image (or capturing an image related to the iris) means, and capturing an image related to the iris refers to capturing an image related to the iris, and then using the image related to the iris. Thus, it may include generating/storing information related to the iris (eg, an iris code) through an iris recognition algorithm.

Recording of the image may be performed as many times as a preset number of times. Specifically, the controller 180 may take an image each time the body is inclined to correspond to different inclinations (preset inclinations), and the number of preset inclinations may correspond to the preset number of times. The preset slope may be set by a user.

The sensing unit 140 (or the sensing unit 140, see FIG. 1) may detect the posture of the main body 100. The posture of the main body 100 should be taken as a meaning including a state in which the main body 100 is placed and a movement (or rotation, inclination, etc.) of the main body 100.

For example, the sensing unit 140 may detect a state in which the main body 100 is placed. The state in which the main body 100 is placed may mean a posture that the main body takes in a real space. For example, when the virtual line corresponding to the longitudinal direction of the main body 100 through the sensing unit 140 corresponds to the virtual line corresponding to the gravitational direction, the main body 100 is vertically vertical. It can be judged that it is in a state.

In addition, the sensing unit 140 may detect that the main body 100 is moved by an external force. In this case, the controller 180 may determine whether the main body 100 has been moved, rotated, or tilted through the sensing unit 140. In addition, when the main body is inclined by an external force, the controller 180 may determine how much the main body 100 is inclined through the sensing unit 140.

As shown in the first drawing of FIG. 3, the image 300 received through the camera 121 is displayed on the display unit 151 in a partial area R of the display area A of the display unit 151 Can be.

Thereafter, as shown in the second drawing of FIG. 3, the controller 180 tilts the main body 100 to correspond to a preset inclination while an image 310a related to the iris is displayed on the image 300. Based on the loss, the image 300 may be photographed.

For example, the controller 180 may determine the degree of inclination (tilt) of the body based on the angle between the virtual line l1 corresponding to the direction of gravity and the virtual line l2 corresponding to the longitudinal direction of the body. have. For example, when the preset inclination is the angle between l1 and l2 is θ, the controller 180 displays the image 310b related to the iris in the image 300 received through the camera 121, and the The image 300 may be photographed based on the fact that the main body is inclined to correspond to a preset inclination (an angle between l1 and l2 is θ).

At this time, as shown in the second drawing of FIG. 3, when an image is captured based on the fact that the body is inclined by θ in the left direction, the image related to the iris included in the image is rotated by θ in the right direction Can be taken as.

A plurality of preset inclinations may be set, and each of them may have different inclinations. Accordingly, the controller 180 may capture the image 300 whenever the image 300 includes an image related to the iris and is inclined to correspond to a plurality of preset inclinations.

Specifically, the controller 180 captures the image based on that the body is inclined at a predetermined first slope so that different images related to the iris are photographed, and then the body is configured with a predetermined first slope different from the first slope. 2 The image can be captured based on the inclination. That is, the photographing may be performed whenever the main body 100 is inclined to correspond to a plurality of preset inclinations.

For example, if a plurality of preset inclinations are set to 10 degrees to the left, 20 degrees to the left, vertical (0 degrees), 10 degrees to the right, and 20 degrees to the right, the controller 180 The image may be photographed based on the inclination of 10 degrees to the left, and the image may be photographed again based on the fact that the main body 100 is inclined 20 degrees to the left. Further, the controller 180 may capture the image based on the fact that the main body 100 is inclined vertically (0 degrees), 10 degrees to the right, and 20 degrees to the right.

On the other hand, when the image is photographed as the main body 100 is tilted to correspond to a certain tilt among preset tilts, the control unit 180 then tilts the main body 100 again to correspond to the certain tilt. Even if you lose, you may not be shooting. For example, if it is sensed that the main body 100 is tilted 10 degrees to the left after photographing is performed based on the tilting of the main body 100 to the left 10 degrees, the controller 180 may not perform the photographing. However, the present invention is not limited thereto, and the controller 180 may be implemented to perform photographing every time it is inclined with the same inclination, or to perform photographing a predetermined number of times even if it is inclined with the same inclination.

In addition, the photographing may be performed on the premise that an image related to the iris is displayed on the image 300. Specifically, when the main body 100 is inclined to correspond to a preset inclination, and it is recognized that the image 300 includes an image related to the iris, the controller 180 may capture the image 300. For example, even if the main body 100 is inclined to correspond to a preset inclination, the controller 180 may not perform photographing if the image 300 does not contain (display) an image related to the iris. .

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 an image related to the user's iris (or an image corresponding to the eye) is output to the image 300 received through the camera, the controller 180 may recognize the image. The controller 180 may recognize an image related to the iris in various ways. For example, the controller 180 may recognize an image related to the iris using an image analysis function for the image.

For example, a template corresponding to the eye (or a template corresponding to the iris) may be previously stored in the memory unit 170, and the controller 180 ) And the image related to the iris included in the image received through the camera are equal to or greater than a preset threshold, the image related to the iris may be recognized.

The controller 180 may capture the image 300 based on the recognition of an image related to the iris in the image 300. After capturing the image 600, the controller 180 extracts a portion corresponding to the iris using an image related to the iris included in the image 600, and information related to the iris using the extracted portion (For example, an iris code) can be created and stored.

On the other hand, the controller 180 is based on the fact that the main body 100 is kept in an inclined state corresponding to the preset inclination for a certain period of time in a state in which an image related to the iris is output on the image 300. 300) can be photographed. In addition, while the image related to the iris is output to the image 300, the controller 180 takes a picture of the image based on the fact that the output of the image related to the iris is maintained for a preset time (a certain time). You can do it. Specifically, while the image 310b related to the iris is output on the image 300, the controller 180 performs a movement (or change) of the image 310b related to the iris for a preset time (a certain time). Based on what is not detected (or that the main body 100 does not move for a preset time (a certain time)), the image 600 may be photographed. The preset time (constant time) may be determined by user setting or control of a controller. For example, the preset time may be a time required to recognize an image related to an iris from an image received through a camera.

In addition, as shown in the second drawing of FIG. 3, the display position of the image 300 may be maintained even when the main body 100 is inclined. Specifically, even if the main body 100 is inclined, the controller 180 may not change an area in which the image 300 is displayed. Accordingly, in the present invention, even if the main body 100 is tilted, the display position of the image 300 is maintained, so that only the image related to the iris included in the image 300 can be rotated and photographed.

Through this configuration, in the present invention, by performing photographing whenever the main body is inclined to correspond to preset inclinations while the image related to the iris is displayed on the image, the images related to the iris are rotated and photographed, that is, the image related to the iris. It is possible to induce the images to be different, so that a plurality of different images related to the iris can be photographed. In addition, in the present invention, different images related to the iris are photographed and stored in advance, so that the state of the iris-related images included in the image received through the camera when the iris is recognized, depending on the surrounding environment, or according to the user's posture. Even if different, iris recognition (or user authentication) may be performed using different images related to the iris to significantly improve the iris recognition rate (or user authentication rate).

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

4A, 4B, and 4C are conceptual diagrams for explaining an image output to a partial area of an output area of the display unit.

In the mobile terminal related to the present invention, an image received through a camera may be displayed in a partial area of the display area of the display unit 151 in various ways.

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

For example, as shown in FIG. 4A, the controller 180 may display an image 410 corresponding to a part of the entire image 400 received through the camera in a partial area of the display area of the display unit 151 ( R1a) can be indicated. A part of the entire image 400 may be pre-designated by user setting. For example, as shown in the first drawing of FIG. 4A, a central part of the entire image 400 having a predetermined size. I can.

As another example, as illustrated in FIG. 4B, the controller 180 may display the entire image 400 received through the camera on a partial area R1b of the display area of the display unit 151.

As another example, as illustrated in FIG. 4C, the controller 180 may extract at least one area including an image corresponding to the user's eye from the entire image 400 received through the camera. Even if the terminal is moved by an external force or screen information included in the image is changed according to the user's movement, the controller 180 may track at least one area including an image corresponding to the user's eye.

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

Thereafter, the controller 180 extracts any one (for example, 420b) of the images 420a and 420b corresponding to at least one area including an image corresponding to the user's eye, and the extracted image The 420b may be displayed on a partial area R1c of the display area of the display unit 151.

While at least a part of the image received through the camera is displayed in a partial area of the display area of the display unit 151, the display unit 151, although not shown, is an image corresponding to the eye (or iris related to the image). Guide information that induces the image) to be displayed may be displayed. The guide information may be displayed in various locations. For example, among the display areas of the display unit 151, the guide information may be displayed in a remaining area other than a partial area in which the image is displayed.

In addition, the mobile terminal according to the present invention may display at least a part of the image received through the camera on a partial area of the display area of the display unit 151 in various ways.

Through this configuration, according to the present invention, a user interface capable of displaying an image received through a camera in various ways may be provided in a partial area of the display area of the display unit 151.

Meanwhile, referring to FIG. 5, FIG. 5 is a conceptual diagram illustrating an interface related to an iris recognition function related to the present invention.

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

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

Hereinafter, a method of photographing a plurality of images related to the iris to be compared when the iris is recognized in the present invention will be described in more detail with reference to the accompanying drawings.

6A, 6B, and 7 are conceptual diagrams illustrating a method for acquiring different images related to an iris according to an embodiment of the present invention.

As shown in the first drawing of FIG. 6A, an image 600 received through the camera 121 may be displayed in a portion of the display area of the display unit 151. In addition, the controller 180 may display a graphic object 620 guiding the degree of inclination of the main body, and notification information 650, 652, 654a indicating a condition in which the photographing is performed, and the like on the display unit 151.

While the image 610 related to the iris is displayed on the image 600, the controller 180 may capture the image 600 based on the body 100 tilting to correspond to a preset tilt.

Here, in FIG. 6A, it is assumed that the preset inclination is 20 degrees to the left, vertical (0 degrees), and 20 degrees to the right. The vertical (0 degree) means a state in which the angle between the virtual line corresponding to the longitudinal direction of the main body and the virtual line corresponding to the gravitational direction is 0 degrees, that is, a state in which the main body 100 is vertically erected.

As the iris registration step enters, the controller 180 may display information 650a, 652, 654a, etc. for photographing, on the display unit 151, as shown in the first drawing of FIG. 6A. have.

Thereafter, as shown in the second drawing of FIG. 6A, the controller 180 corresponds to a preset first inclination while the image 600 displays an image 610 related to the iris. When inclined to be inclined (for example, when the main body 100 is inclined 20 degrees to the left), the image 600 can be photographed. In this case, information (tilt information, angle information, etc.) indicating the degree of inclination of the main body may be displayed on the graphic object 620 that guides the degree of inclination of the main body.

When capturing of the image 600 is performed, the controller 180 may output information 650b and 654b for indicating a condition for performing the next capturing to the display unit 151.

For example, the controller 180 may transmit at least some of the information 650a, 652, and 654a notifying the condition for performing the first photographing to the information 650b indicating the condition for performing the second photographing. 654b).

Thereafter, as shown in the third drawing of FIG. 6A, the controller 180 displays the image 610 related to the iris in the image 600, and the main body 100 is different from the first inclination. The image 600 may be photographed based on the inclination to correspond to the second inclination (for example, the main body 100 being erected vertically (0 degrees)).

Likewise, when the image 600 is photographed, the controller 180 may output information 650c and 654c to inform the condition for the next photographing to be performed on the display unit 151. For example, the controller 180 may change information 650b and 654b informing of a condition for performing the second photographing to information 650c and 654c informing of a condition for performing a third photographing.

Likewise, the controller 180 corresponds to a third slope different from the second slope in a state where an image related to the iris is displayed on the image 600, as shown in the fourth drawing of FIG. 6A. The image 600 may be photographed based on the inclination so that the body is inclined 20 degrees to the right.

Through this configuration, in the present invention, an image in which an image related to the iris is rotated 20 degrees to the right, an image related to the iris is horizontal to the ground direction, and an image related to the iris is rotated 20 degrees to the left. . Here, the degree of inclination of the image related to the iris may be defined based on a virtual line connecting at least two points of the image related to the iris (the image corresponding to the user's eye). For example, the two points are tears. It may be a point corresponding to a pocket and a point corresponding to the tail of the eye.

Meanwhile, in the present invention, a graphic object for indicating the degree of inclination of the main body and information for indicating a condition for performing photographing may be output in various ways.

In FIG. 6B, it is assumed that the preset inclination is 45 degrees to the left and 45 degrees to the right.

As shown in the first drawing of FIG. 6B, the display unit 151 includes notification information (tilt information) 650c indicating a condition in which photographing is performed, and a first graphic object 660 for guiding the degree of inclination of the body. And a second graphic object 662 may be displayed. The first graphic object 660 may have a shape of a protractor and may include scale information indicating an angle. Also, the display method and display position of the first graphic object 660 may not be changed even if the main body is inclined.

Meanwhile, at least one of a display method and a display position of the second graphic object 662 may be changed based on the inclination of the main body 100. For example, the second graphic object 662 may be displayed while being rotated by the predetermined angle in a direction opposite to one direction based on the fact that the body 100 is inclined at a certain angle in one direction. For example, as shown in the second drawing of FIG. 6B, when the main body 100 is inclined 45 degrees to the left, the second graphic object 662 is inclined by 45 degrees to the right opposite to the left and displayed. Can be. That is, even if the main body 100 is inclined, the second graphic object 662 may be displayed to correspond to a virtual line corresponding to the direction of gravity.

In addition, an icon 664 may be output to the first graphic object 660 so as to correspond to an angle corresponding to a tilt (a preset tilt) at which photographing is performed. For example, when the inclination is 45 degrees to the left, the icon 664 may be displayed at a position corresponding to 45 degrees to the right, as shown in the first drawing of FIG. 6B. This is because when the main body 100 is inclined to the left, the second graphic object 662 is rotated to the right and displayed.

Here, in a state in which an image related to the iris is displayed on the image 600, taking an image based on that the main body 100 is inclined to correspond to a preset inclination means that the image is taken by the inclination of the main body 100. 2 Based on the rotation of the graphic object 662 and the correspondence between the second graphic object 662 and the icon 664 by the rotation, it may be considered to mean that the image 600 is captured.

For example, as shown in the first and second drawings of FIG. 6B, the controller 180 may tilt the body while an image related to the iris is displayed on the image 600 received through the camera 121. The ground and the second graphic object 662 may be rotated. Thereafter, when the second graphic object 662 corresponds to an icon 664 guiding a preset inclination, the controller 180 may capture the image 600.

When the photographing is performed, the control unit 180 displays the icon 664 to correspond to an angle corresponding to a slope (a preset slope) at which the next photographing is performed, as shown in the third drawing of FIG. 6B. Can be changed.

Thereafter, as shown in the fourth drawing of FIG. 6B, while the image 600 displays an image related to the iris, the controller 180 displays the second graphic object as the main body 100 is tilted. Based on the fact that 662 corresponds to the icon 664 whose display position is changed, the image 600 may be photographed.

In addition, the controller 180 may variously output a graphic object indicating the degree of inclination of the main body in various ways and notification information indicating a condition under which photographing is performed.

On the other hand, even if the main body 100 is inclined to correspond to a preset inclination, when the image related to the iris is not displayed on the image or the movement of the main body 100 is detected, the controller 180 captures the image. May not be performed. In addition, when the image related to the iris is not displayed on the image or the movement of the main body 100 is detected, the controller 180 outputs notification information indicating a condition necessary for the shooting to be performed to the display unit 151. can do.

For example, as shown in the first drawing of FIG. 7, when the preset inclination is 15 degrees to the left, the controller 180 is in a state in which an image related to the iris is displayed on the image received through the camera 121. Even if the main body 100 is inclined to correspond to a preset inclination, when the movement of the main body 100 is detected, photographing may not be performed. In addition, the controller 180 may not perform photographing even when the image related to the iris displayed in the image moves (ie, the subject corresponding to the eye moves), not the movement of the main body 100. .

Thereafter, as shown in the second drawing of FIG. 7, the controller 180 may output notification information 656 informing of a condition necessary for the shooting to be performed.

Meanwhile, in the present invention, it is possible to capture an image received through a camera based on various conditions. Hereinafter, an image capturing method (an iris registration method) according to another embodiment of the present invention will be described in more detail with reference to the accompanying drawings.

8A and 8B are conceptual diagrams illustrating a method for acquiring different images related to an iris according to another exemplary embodiment of the present invention.

Referring to FIG. 8A, the controller 180 may overlap an image 800 received through the camera 121 with a guide image 820a guiding a position where an image related to the iris is to be output. Thereafter, the controller 180 may capture the image 800 based on the correspondence of the image 810a related to the iris to the guide image 820a.

Also, the controller 180 may change at least one of the display size and display angle of the guide image based on the image 800 so that different images related to the iris are captured (820a to 820b). .

Thereafter, the controller 180 may capture the image 800 based on the correspondence of the iris-related image 810b to the changed guide image 820a.

In this case, the images 810a and 810b related to the iris may be different from each other. This is because the image 800 is photographed based on the correspondence between the guide image and the image related to the iris, and the guide image is changed after photographing.

For example, when entering the iris registration step, the controller 180 displays the image 800 received through the camera on a partial area of the display area of the display unit, as shown in the first drawing of FIG. 8A, and the A guide image 820a guiding a position in which an image related to the iris is to be output may be displayed (overlapped) on at least a part of the image 800.

Thereafter, the controller 180 displays an image 810a related to the iris on the image 800 by the movement of the user, and the image 810a related to the iris corresponds to the guide image 820a. , The image 800 may be photographed.

Here, the correspondence between the iris-related image 810a and the guide image 820a means that, for example, the image corresponding to the pupil included in the image corresponds to the original image included in the guide image or the iris-related image. At least two points of the image (for example, a point corresponding to a tear bag and a point corresponding to an eye tail) may include a point corresponding to two preset points of the guide image, and the like.

When the photographing is performed, the controller 180 may change the display size of the guide image 810a. For example, the controller 180 may reduce the display size of the guide image 820a based on the photographing of the image 800 as shown in the third drawing of FIG. 8A. have. When the reduced guide image 820b is displayed on the image 800 and the image 810b related to the iris included in the image 800 corresponds to the reduced guide image 820b, the controller 180 ) May capture the image 800 as shown in the fourth drawing of FIG. 8A. In this case, as an example, the user may move the main body away from the user's eyes to reduce the display size of the image 810b related to the iris included in the image.

As another example, the controller 180 photographs the image based on the correspondence between the image 810c related to the iris included in the image and the guide image 820c, as shown in the first drawing of FIG. 8B. , As shown in the second drawing of FIG. 8B, the guide image 820c may be rotated (820d). As shown in the third drawing of FIG. 8B, when an image 810d related to an iris corresponds to the rotated guide image 820d, the controller 180 may capture the image 800. For example, the user tilts the main body 100 to correspond the image 810d related to the iris to the rotated guide image 820d, or, while the main body 100 is fixed, the user's head is tilted to rotate the rotated guide image 820d. The rotated guide image 820d and the iris-related image 810d may be associated with the guide image 820d in various ways, such as matching the iris-related image 810d.

In this case, even if the image 800 is photographed, a guide image may not be included in the photographed image.

Through this configuration, in the present invention, different images related to the iris can be obtained by changing the display size of the guide image or rotating the guide image.

As described above, the present invention may capture a plurality of images related to an iris used for iris recognition, and images related to the plurality of irises may 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 irises.

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

The present invention described above can be implemented as a computer-readable code on a medium on which a program is recorded. The computer-readable medium includes all types of recording devices that store data that can be read by a computer system. Examples of computer-readable media include hard disk drives (HDDs), solid state disks (SSDs), silicon disk drives (SDDs), ROMs, RAM, CD-ROMs, magnetic tapes, floppy disks, optical data storage devices, etc. There is also a carrier wave (for example, transmission over the Internet) also includes the implementation of the form. In addition, the computer may include the control unit 180 of the terminal. Therefore, the detailed description above should not be construed as restrictive in all respects and should be considered as illustrative. The scope of the present invention should be determined by reasonable interpretation of the appended claims, and all changes within the equivalent scope of the present invention are included in the scope of the present invention.
