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 display unit 151 displays (outputs) information processed by the mobile terminal 100. For example, the display unit 151 may display execution screen information of an application program driven by the mobile terminal 100 or UI (User Interface) and GUI (Graphic User Interface) information according to the execution screen information .

In addition, the 3D thumbnail image may generate a left image thumbnail and a right image thumbnail from the left image and right image of the original image frame, respectively, and may be generated as one image as they are combined. In general, a thumbnail means a reduced image or a reduced still image. The left image thumbnail and the right image thumbnail generated in this way are displayed on the screen with a difference of the left and right distance by the depth corresponding to the parallax between the left image and the right image, thereby exhibiting a stereoscopic spatial feeling.

The left and right images necessary for realizing the three-dimensional stereoscopic image can be displayed on the stereoscopic display unit by the stereoscopic processing unit. The stereoscopic processing unit receives a 3D image (an image at a reference time point and an image at an expansion point), sets a left image and a right image therefrom, or receives a 2D image and converts it into a left image and a right image.

When the user wears the glass-type mobile terminal 400, the display unit 451 may be arranged to correspond to at least one of the left eye and the right eye so as to provide images directly to the user's eyes. In this figure, the display unit 451 is located at a portion corresponding to the right eye so that an image can be output toward the user's right eye.

The display unit 451 can project an image to the user's eyes using a prism. Further, the prism may be formed to be transmissive so that the user can view the projected image and the general view of the front (the range that the user views through the eyes) together.

As described above, the image output through the display unit 451 may be overlapped with the general view. The mobile terminal 400 can provide an Augmented Reality (AR) in which a virtual image is superimposed on a real image or a background and displayed as a single image using the characteristics of the display.

The camera 421 is disposed adjacent to at least one of the left eye and the right eye, and is configured to photograph a forward image. Since the camera 421 is positioned adjacent to the eyes, the camera 421 can acquire a scene viewed by the user as an image.

Although the camera 421 is provided in the control module 480 in this figure, it is not limited thereto. The camera 421 may be installed in the frame portion, or may be provided in a plurality of ways to obtain a stereoscopic image.

The glass-type mobile terminal 400 may include user input units 423a and 423b operated to receive control commands.

Next, a communication system that can be implemented through the mobile terminal 100 according to the present invention will be described.

First, the communication system may use different wireless interfaces and / or physical layers. For example, wireless interfaces that can be used by a communication system include Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA) ), Universal mobile telecommunication systems (UMTS) (in particular Long Term Evolution (LTE), Long Term Evolution-Advanced (LTE-A)), Global System for Mobile Communications May be included.

Hereinafter, for the sake of convenience of description, the description will be limited to CDMA. However, it is apparent that the present invention can be applied to all communication systems including an OFDM (Orthogonal Frequency Division Multiplexing) wireless communication system as well as a CDMA wireless communication system.

A CDMA wireless communication system includes at least one terminal 100, at least one base station (BS) (also referred to as a Node B or Evolved Node B), at least one Base Station Controllers (BSCs) , And a Mobile Switching Center (MSC). The MSC is configured to be coupled to a Public Switched Telephone Network (PSTN) and BSCs. The BSCs may be paired with the BS via a backhaul line. The backhaul line may be provided according to at least one of E1 / T1, ATM, IP, PPP, Frame Relay, HDSL, ADSL or xDSL. Thus, a plurality of BSCs may be included in a CDMA wireless communication system.

Each of the plurality of BSs may comprise at least one sector, and each sector may comprise an omnidirectional antenna or an antenna pointing to a particular direction of radial emission from the BS. In addition, each sector may include two or more antennas of various types. Each BS may be configured to support a plurality of frequency assignments, and a plurality of frequency assignments may each have a specific spectrum (e.g., 1.25 MHz, 5 MHz, etc.).

The intersection of sector and frequency assignment may be referred to as a CDMA channel. The BS may be referred to as a base station transceiver subsystem (BTSs). In this case, a combination of one BSC and at least one BS may be referred to as a "base station ". The base station may also indicate a "cell site ". Alternatively, each of the plurality of sectors for a particular BS may be referred to as a plurality of cell sites.

A broadcast transmission unit (BT) transmits a broadcast signal to terminals 100 operating in the system. The broadcast receiving module 111 shown in FIG. 1 is provided in the terminal 100 to receive a broadcast signal transmitted by the BT.

In addition, a Global Positioning System (GPS) may be associated with the CDMA wireless communication system to identify the location of the mobile terminal 100. The satellite 300 aids in locating the mobile terminal 100. Useful location information may be obtained by two or more satellites. Here, the position of the mobile terminal 100 can be tracked using all the techniques capable of tracking the location as well as the GPS tracking technology. Also, at least one of the GPS satellites may optionally or additionally be responsible for satellite DMB transmission.

The location information module 115 included in the mobile terminal is for detecting, computing, or identifying the location of the mobile terminal, and may include a Global Position System (GPS) module and a WiFi (Wireless Fidelity) module. Optionally, the location information module 115 may perform any of the other functions of the wireless communication unit 110 to obtain data relating to the location of the mobile terminal, in addition or alternatively.

The GPS module 115 calculates distance information and accurate time information from three or more satellites and then applies trigonometry to the calculated information to accurately calculate three-dimensional current location information according to latitude, longitude, and altitude can do. At present, a method of calculating position and time information using three satellites and correcting an error of the calculated position and time information using another satellite is widely used. In addition, the GPS module 115 can calculate speed information by continuously calculating the current position in real time. However, it is difficult to accurately measure the position of the mobile terminal by using the GPS module in the shadow area of the satellite signal as in the room. Accordingly, a WPS (WiFi Positioning System) can be utilized to compensate the positioning of the GPS system.

The WiFi Positioning System (WPS) is a system in which a mobile terminal 100 uses a WiFi module included in the mobile terminal 100 and a wireless AP (wireless access point) transmitting or receiving a wireless signal with the WiFi module, Is a technology for tracking a location of a wireless local area network (WLAN) using WiFi.

The WiFi location tracking system may include a Wi-Fi location server, a mobile terminal 100, a wireless AP connected to the mobile terminal 100, and a database in which certain wireless AP information is stored.

The mobile terminal 100 connected to the wireless AP can transmit a location information request message to the Wi-Fi location server.

The Wi-Fi position location server extracts information of the wireless AP connected to the mobile terminal 100 based on the location information request message (or signal) of the mobile terminal 100. The information of the wireless AP connected to the mobile terminal 100 may be transmitted to the Wi-Fi location server through the mobile terminal 100 or may be transmitted from the wireless AP to the Wi-Fi location server.

The information of the wireless AP to be extracted based on the location information request message of the mobile terminal 100 includes a MAC address, an SSID (Service Set IDentification), a Received Signal Strength Indicator (RSSI), a Reference Signal Received Power (RSRP) Reference Signal Received Quality), channel information, Privacy, Network Type, Signal Strength, and Noise Strength.

As described above, the Wi-Fi position location server can receive the information of the wireless AP connected to the mobile terminal 100 and extract the wireless AP information corresponding to the wireless AP to which the mobile terminal is connected from the pre-established database. In this case, the information of any wireless APs stored in the database includes at least one of MAC address, SSID, channel information, privacy, network type, radius coordinates of the wireless AP, building name, Available), the address of the AP owner, telephone number, and the like. At this time, in order to remove the wireless AP provided using the mobile AP or the illegal MAC address in the positioning process, the Wi-Fi location server may extract only a predetermined number of wireless AP information in order of RSSI.

Then, the Wi-Fi location server can extract (or analyze) the location information of the mobile terminal 100 using at least one wireless AP information extracted from the database. And compares the received information with the received wireless AP information to extract (or analyze) the location information of the mobile terminal 100.

As a method for extracting (or analyzing) the position information of the mobile terminal 100, a Cell-ID method, a fingerprint method, a triangulation method, and a landmark method can be utilized.

The Cell-ID method is a method of determining the position of the mobile station with the strongest signal strength among neighboring wireless AP information collected by the mobile terminal. Although the implementation is simple, it does not cost extra and it can acquire location information quickly, but there is a disadvantage that positioning accuracy is lowered when the installation density of the wireless AP is low.

The fingerprint method collects signal strength information by selecting a reference position in a service area, and estimates the position based on the signal strength information transmitted from the mobile terminal based on the collected information. In order to use the fingerprint method, it is necessary to previously convert the propagation characteristics into a database.

The triangulation method is a method of calculating the position of the mobile terminal based on the coordinates of at least three wireless APs and the distance between the mobile terminals. (Time of Arrival, ToA), Time Difference of Arrival (TDoA) in which a signal is transmitted, and the time difference between the wireless AP and the wireless AP, in order to measure the distance between the mobile terminal and the wireless AP. , An angle at which a signal is transmitted (Angle of Arrival, AoA), or the like.

The landmark method is a method of measuring the position of a mobile terminal using a landmark transmitter that knows the location.

Various algorithms can be utilized as a method for extracting (or analyzing) the location information of the mobile terminal.

The extracted location information of the mobile terminal 100 is transmitted to the mobile terminal 100 through the Wi-Fi location server, so that the mobile terminal 100 can acquire the location information.

The mobile terminal 100 may be connected to at least one wireless AP to obtain location information. At this time, the number of wireless APs required to acquire the location information of the mobile terminal 100 may be variously changed according to the wireless communication environment in which the mobile terminal 100 is located.

1, the mobile terminal according to the present invention may include Bluetooth (registered trademarks), Radio Frequency Identification (RFID), Infrared Data Association (IrDA), Ultra Wideband (UWB), ZigBee, Field Communication), and Wireless USB (Wireless Universal Serial Bus).

Among them, the NFC module provided in the mobile terminal supports the non-contact type short-range wireless communication between the terminals at a distance of about 10 cm. The NFC module may operate in either a card mode, a reader mode, or a P2P mode. In order for the NFC module to operate in the card mode, the mobile terminal 100 may further include a security module for storing card information. Here, the security module may be a physical medium such as a UICC (e.g., a SIM (Subscriber Identification Module) or a USIM (Universal SIM)), a Secure micro SD and a sticker, or a logical medium For example, embeded SE (Secure Element)). Data exchange based on SWP (Single Wire Protocol) can be made between NFC module and security module.

When the NFC module is operated in the card mode, the mobile terminal can transmit the stored card information to the outside such as a conventional IC card. Specifically, if the mobile terminal storing the card information of the payment card such as a credit card or a bus card is brought close to the fare payment machine, the mobile local payment can be processed, and the mobile terminal storing the card information of the access card can be accessed If you are close to the time, the approval process for access may begin. Cards such as credit cards, transportation cards, and access cards are mounted on the security module in the form of an applet, and the security module can store card information on the mounted card. Here, the card information of the payment card may be at least one of a card number, balance, and usage details, and the card information of the access card may include at least one of a name, a number (e.g., It can be one.

When the NFC module is operated in the reader mode, the mobile terminal can read data from an external tag. At this time, the data received from the mobile terminal by the tag may be coded into a data exchange format (NFC Data Exchange Format) defined by the NFC Forum. In addition, the NFC Forum defines four record types. Specifically, the NFC forum defines four RTDs (Record Type Definitions) such as Smart Poster, Text, Uniform Resource Identifier (URI), and General Control. If the data received from the tag is a smart poster type, the control unit executes a browser (e.g., an Internet browser), and if the data received from the tag is a text type, the control unit can execute the text viewer. When the data received from the tag is a URI type, the control unit executes the browser or makes a telephone call, and if the data received from the tag is a general control type, it can execute appropriate operations according to the control contents.

When the NFC module is operated in a peer-to-peer (P2P) mode, the mobile terminal can perform P2P communication with another mobile terminal. At this time, LLCP (Logical Link Control Protocol) may be applied to P2P communication. For P2P communication, a connection can be created between the mobile terminal and another mobile terminal. At this time, the generated connection can be divided into a connectionless mode in which one packet is exchanged and terminated, and a connection-oriented mode in which packets are exchanged consecutively. Through P2P communications, data such as business cards, contact information, digital photos, URLs in electronic form, and setup parameters for Bluetooth and Wi-Fi connectivity can be exchanged. However, since the usable distance of NFC communication is short, the P2P mode can be effectively used to exchange small-sized data.

Hereinafter, embodiments related to a control method that can be implemented in a mobile terminal configured as above will be described with reference to the accompanying drawings. It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

In another embodiment, the control unit 180 can identify the electronic device 200 based on the location information of the mobile terminal 100. [ Specifically, the controller 180 can identify the electronic device 200 displayed on the preview image by comparing the location information of the mobile terminal 100 with the location information of the electronic device 200.

Although it is preferable to use GPS information as location information, it may be difficult to acquire GPS information in a room. Accordingly, the controller 180 may utilize a Wifi (Wifi Position Service) method using a wireless Internet, a method using Bluetooth, and a method using RFID.

The local area communication module 114 of the mobile terminal 100 can perform short-range wireless communication with the electronic device 200. [ To this end, the electronic device 200 may also include a short-range communication module.

Hereinafter, a method of arranging home appliances using an augmented reality according to an embodiment of the present invention will be described.

4 is a flowchart illustrating a method of arranging home appliances using an augmented reality according to an embodiment of the present invention. FIG. 5 is a schematic block diagram of a mobile terminal for performing a home appliance arrangement method using an augmented reality according to an embodiment of the present invention. Referring to FIG.

4 may be performed by the mobile terminal 100, but may be performed by the mobile terminal 100 and the server 300 according to an embodiment of the present invention.

For convenience of explanation, the description will be made with reference to FIGS. 4 and 5, focusing on an embodiment in which the home appliance arrangement method is performed by the mobile terminal 100. FIG.

Referring to FIGS. 4 and 5, the mobile terminal 100 may acquire an image including a layout space of the home appliances (S100).

Specifically, the control unit 180 of the mobile terminal 100 may acquire an image including a placement space of the home appliances using the camera 121, and display the acquired image through the display unit 151. FIG. As described above with reference to FIG. 3, the mobile terminal 100 may enter the augmented reality mode according to the execution of an application installed in the memory 170. That is, the application may support an augmented reality mode. When the mobile terminal 100 enters the augmented reality mode, the mobile terminal 100 can display a preview image acquired through the camera 121 through the display unit 151. [ That is, the image obtained in step S100 may be a preview image, but is not necessarily the preview image.

The mobile terminal 100 may obtain the size information of the layout space from the obtained image (S110).

The control unit 180 can recognize the layout space of the home appliances from the image obtained in step S100. For example, the size information acquisition module 181 executed by the control unit 180 recognizes the layout space of the home appliance using various known image recognition techniques, or receives the selection input of the layout space from the user, It can also be recognized.

The size information acquisition module 181 can acquire the size information of the layout space by calculating the size of the recognized layout space.

For example, the size information acquisition module 181 may calculate the size of the layout space using the lens equation. The lens equation means an equation for calculating the size of the subject based on the size of the image formed on the image sensor of the camera 121, the plane of the image sensor, the distance between the lenses of the camera 121, and the distance between the lens and the subject. do. Specifically, the size of the subject is S, the size of the image formed on the image sensor is S ', the distance between the plane of the image sensor and the lens is f, and the distance between the lens and the subject is d. In this case, the size of the subject S = (S '* d) / f.

Based on the lens equation, the size information acquisition module 181 may calculate at least one of the size of the arrangement space, i.e., the width, height, and height of the arrangement space. By calculating the size of the arrangement space, the size information acquisition module 181 can obtain the size information of the arrangement space.

According to the embodiment, in addition to using the lens equation, the size information acquisition module 181 may calculate the size of the layout space using various known algorithms for calculating or estimating the size of the subject.

Steps S100 and S110 will be described in more detail with reference to the exemplary diagram shown in FIG.

6 is an exemplary view of an image including an arrangement space of home appliances obtained through a camera of the mobile terminal.

Referring to FIG. 6, the mobile terminal 100 may enter the augmented reality mode according to the execution of an application installed in the memory 170. The control unit 180 controls the camera 121 to acquire the preview image 500 and display the obtained preview image 500 on the display unit 180. [

For example, the preview image 500 may include at least one layout space for arranging at least one home appliance. In FIG. 6, an example in which one layout space 510 is included in the preview image 500 is shown, but the number of layout spaces may vary.

The control unit 180 can recognize the layout space 510 included in the preview image 500. [ The method for the controller 180 to recognize the layout space 510 may be variously implemented.

For example, the household appliances may be disposed adjacent to or close to a wall of a specific space. Accordingly, the control unit 180 recognizes the area of the preview image 500 in which the wall is exposed, and recognizes the area having the size of the recognized area equal to or larger than the predetermined size as the layout space.

The control unit 180 may receive the selection input of the layout space 510 from the preview image 500 through the user input unit 123 or the like. For example, when the user input unit 123 corresponds to a touch screen, the control unit 180 receives a touch input for an area corresponding to the layout space 510 among the preview images 500 displayed through the display unit 151 . In response to the received touch input, the control unit 180 can recognize the layout space 510.

The control unit 180 may obtain the size information of the layout space 510 by calculating the size of the recognized layout space 510. [ As described above, the controller 180 can obtain the size information by calculating the size of the placement space 510 using various known algorithms for estimating the lens equation or the size of the subject. The size information may include at least one of a width, a length, and a height of the layout space 510.

According to the embodiment, the control unit 180 may store the acquired size information in the memory 170. [

4 and 5 will be described again.

The mobile terminal 100 may analyze the colors included in the acquired image and obtain the color information of the recommended home appliance related to the layout space based on the analysis result (S120).

The step S120 will be described in more detail with reference to FIGS. 7 to 8B.

FIG. 7 is a flowchart illustrating an operation of acquiring color information of a recommended home appliance by analyzing colors included in the obtained image.

Referring to FIG. 7, the mobile terminal 100 may extract colors included in the acquired image (S121). The control unit 180 may transmit the data corresponding to the preview image to the display unit 151 in order to display the preview image obtained from the camera 121 through the display unit 151. [ At this time, the color information acquisition module 182 executed by the control unit 180 can extract the colors included in the preview image using the color values of each pixel included in the data.

The mobile terminal 100 may set a representative color for the acquired image based on the ratio of each extracted color (S122).

The color information acquisition module 182 can calculate the ratio of each of the colors included in the preview image. For example, the color information acquisition module 182 may calculate the ratio of each of the colors included in the preview image by calculating the number of pixels having a specific color value.

As a result of calculation, the color information acquisition module 182 can set a color having the highest ratio of the extracted colors as the representative color for the preview image. For example, it is assumed that the ratio of 'brown' in the preview image is 0.4, the ratio of 'white' is 0.3, the ratio of 'dark gray' is 0.2, and the ratio of 'dark brown' is 0.1. In this case, the color information acquiring module 182 can set 'brown' having the highest ratio as a representative color for the preview image.

The color information acquisition module 182 may further set at least one candidate color based on the ratio of each of the hues. For example, the color information acquisition module 182 may set 'White', which is the next highest ratio to 'Brown', as the candidate color.

That is, the color information acquisition module 182 can automatically set the representative color for the preview image based on the ratio of each of the colors included in the preview image.

According to an embodiment, the control unit 180 may receive a request to select a representative color from the user. In response to the received selection request, the controller 180 may set the selected color to a representative color for the preview image.

The representative color for the preview image may refer to the overall color tone of the peripheral space of the arrangement space of the home appliance.

Steps S121 to S122 will be described in more detail with reference to FIGS. 8A to 8B.

8A and 8B are illustrations of operations for setting representative colors of the image described in FIG.

8A, the color information acquisition module 182 executed by the control unit 180 or the control unit 180 may extract the colors C1 to C4 included in the preview image 500. FIG. For example, the control unit 180 may extract all the colors included in the preview image 500, or may extract only colors included in a predetermined ratio or more.

In FIG. 8A, it is assumed that the controller 180 extracts the first color C1 through the fourth color C4. In addition, the first color C1 is 'brown', the second color C2 is 'white', the third color C3 is 'dark gray', the fourth color C4 is 'dark brown' .

The control unit 180 can automatically set the representative color for the preview image 500 based on the ratio of the extracted first color C1 to the fourth color C4. For example, the controller 180 may set the first color C1 having the highest ratio as the representative color. According to the embodiment, the controller 180 may further set the second highest color ratio C2 as the candidate color.

Referring to FIG. 8B, the controller 180 may display the representative color setting window 530 including the extracted first color C1 through the fourth color C4 through the display unit 151. FIG. 8B, the representative color setting window 530 is displayed on the right side of the display unit 151. However, the display position of the representative color setting window 530 is freely changed based on the position of the placement space 510 .

The control unit 180 may display the extracted first color C1 to the fourth color C4 in the representative color setting window 530. [ For example, the controller 180 may display the colors C1 to C4 in an aligned form based on the ratios of the first color C1 to the fourth color C4, but the present invention is not limited thereto.

The control unit 180 may receive a request through the user input unit 123 to select any one of the colors C1 to C4 displayed in the representative color setting window 530. [ For example, when a request to select the first color C1 is input through the user input unit 123 (e.g., a touch screen), the controller 180 sets the first color C1 as a representative color for the preview image 500 . The controller 180 may further display a setting window for setting a candidate color and may select a second color C2 to a fourth color C4 based on the selection request received through the user input unit 123. [ May be set as a candidate color.
