JP6330442B2 - Terminal device, display control program, and display control method - Google Patents

Description

  The present invention relates to a terminal device, a display control program, and a display control method.

  For example, an automatic ticket gate disposed in a baggage inspection area at an airport or the like is known in which a two-dimensional code reading unit and an RFID (Radio Frequency Identification) reading unit are incorporated. The automatic ticket gate reads information such as passenger information from a two-dimensional code image or an RFID tag according to the needs of the user. In an automatic ticket gate incorporating a two-dimensional code reading unit and an RFID reading unit, the reading area of the two-dimensional code reading unit and the reading area of the RFID reading unit are close to each other.

  The RFID reader transmits a carrier wave for reading the RFID tag within the RFID communication range of a predetermined transmission distance from the vicinity of the reading area. Furthermore, the portable terminal enters the RFID reading range as it approaches the reading area within the RFID communication range. The RFID reading unit reads information from the RFID tag by communicating with the RFID tag in the portable terminal that has entered the RFID reading range. And the automatic ticket gate can restrict a passenger based on the reading result of the information from the RFID tag in the portable terminal.

  The two-dimensional code reading unit reads information from the image-recognized two-dimensional code image by recognizing the two-dimensional code image displayed on the display screen of the portable terminal in the reading area. The automatic ticket gate can limit the number of passengers based on the result of reading information from the two-dimensional code image.

  However, even if the user wants to prioritize reading information from the two-dimensional code image, the automatic ticket checker is close to the reading area of the two-dimensional code reading unit and the RFID reading unit. Recognition is delayed, and the portable terminal first enters the RFID reading range. As a result, information is read from the RFID tag before reading the information of the two-dimensional code image.

  For example, it is assumed that a user uses a single mobile terminal to use an RFID tag for payment of a train fare and a two-dimensional code for boarding an airplane. In an automatic ticket gate on board an airplane, priority is given to reading information from a two-dimensional code image. However, in the automatic ticket gate, the image recognition of the two-dimensional code image is delayed and the mobile terminal enters the RFID reading range, and the information from the RFID tag is read before the information of the two-dimensional code image is read. It is not obtained and information reading fails.

  An object of one aspect is to provide a terminal device, a display control program, and a display control method that preferentially read information of an identification information image.

  One proposal includes an identification unit, a detection unit, and a control unit. The identification unit identifies the identification information image being displayed on the display screen. The detection unit detects a signal for reading a radio tag when the identification information image is identified by the identification unit. Further, when the signal is detected by the detection unit, the control unit enlarges and displays the identification information image being displayed on the display screen.

  The information of the identification information image is read preferentially.

The disclosed technology is not limited by the present embodiment. Moreover, you may combine suitably each Example shown below in the range which does not cause contradiction.

  FIG. 1 is an explanatory diagram illustrating an example of an information reading system according to this embodiment. An information reading system 1 shown in FIG. 1 includes a reader 2 and a portable terminal 3, and the reader 2 reads specific information, for example, airplane occupant information, from the portable terminal 3. The mobile terminal 3 is a terminal device that is carried by a passenger boarding an airplane at an airport, for example. The reader 2 is built in, for example, an automatic ticket gate located at a baggage inspection area such as an airport or at a boarding gate, and boarded from the portable terminal 3 using the two-dimensional code reading function or the RFID reading function. The person information.

  The reader 2 includes a two-dimensional code reading unit 11, an RFID reading unit 12, an output unit 13, and a control unit 14. The two-dimensional code reading unit 11 recognizes an image of an identification information image such as a two-dimensional code image displayed on the display screen of the mobile terminal 3 in the reading area 2A (see FIG. 3). Note that the two-dimensional code reading unit 11 recognizes the identification information image using a zoom function or an autofocus function of a camera unit (not shown). The two-dimensional code reader 11 reads information from the image-recognized two-dimensional code image. The RFID reader 12 outputs a carrier wave for reading detection from the vicinity of the reading area 2A, communicates with the RFID tag in the portable terminal 3 using the carrier wave, and reads information from the RFID tag. The carrier wave is a signal for reading detection using a frequency band of HF (High Frequency). The RFID reader 12 transmits a carrier wave in the RFID communication range of a predetermined transmission distance from the vicinity of the reading area 2A. Further, the RFID reading unit 12 communicates with the RFID tag in the portable terminal 3 existing in the RFID reading range within the RFID communication range using the carrier wave, and reads information from the RFID tag. The RFID reading range is within about 2 cm from the vicinity of the reading area when the RFID communication range is about 10 cm from the vicinity of the reading area 2A. The reading area of the RFID reading unit 12 is close to the reading area 2A of the two-dimensional code reading unit 11.

  The output unit 13 is an output interface such as a ticket issuing unit that issues a boarding guide ticket, for example. The control unit 14 controls the entire reader 2. The control unit 14 reads the passenger information from the portable terminal 3 by the two-dimensional code reading unit 11 or the RFID reading unit 12, and controls the output unit 13 based on the reading result.

  The mobile terminal 3 corresponds to a wireless terminal such as a mobile phone or a smartphone, for example, and includes a wireless unit 21, an audio input / output unit 22, a camera 23, a display unit 24, a touch panel 25, an RFID tag 26, and RFID control. A unit 27, a storage unit 28, and a processor 29. The wireless unit 21 is a communication interface that is connected to the wireless antenna 21A and manages wireless communication with a wireless communication network (not shown). The audio input / output unit 22 is an interface that is connected to the speaker 22A and the microphone 22B to input / output audio.

  The camera 23 has a function of capturing an image such as a still image as a moving image. The display unit 24 is an output interface that displays various information on the screen. The touch panel 25 is an input interface that detects a touch operation in cooperation with the display screen of the display unit 24. The RFID tag 26 is a recording medium on which ID information such as passenger information is recorded, for example. The RFID control unit 27 is connected to the RFID antenna 27 </ b> A and controls the RFID tag 26 according to the carrier wave from the RFID reading unit 12 in the reader 2.

  The storage unit 28 includes a ROM (Read Only Memory) 28A and a RAM (Random Access Memory) 28B. The ROM 28A is an area for storing various programs such as a display control program. The RAM 28B has an area for storing various types of information. For example, the RAM 28B is an area for storing an enlarged image obtained by enlarging a two-dimensional code image to be described later. The processor 29 controls the entire mobile terminal 3. The processor 29 reads the display control program stored in the ROM 28A and configures various processes as functions based on the read display control program.

  The processor 29 operates using the identification unit 31, the detection unit 32, and the control unit 33 as functions. The identification unit 31 identifies the presence of a two-dimensional code image on the display screen of the display unit 24. For example, the mobile terminal 3 accesses a check-in site such as an airline and acquires a two-dimensional code in which the passenger information is recorded from the site or from the page using the imaging function of the camera 23. . Further, the processor 29 displays the acquired two-dimensional code image on the display unit 24 on the screen.

  The detection unit 32 determines whether or not a carrier wave from the RFID reading unit 12 has been detected in a state where the identification unit 31 has identified the presence of the two-dimensional code image on the display screen. The control unit 33 generates an enlarged image obtained by enlarging the two-dimensional code image to the display screen size in a state where the presence of the two-dimensional code image on the display screen is identified, and stores the generated enlarged image in the RAM 28B. FIG. 2 is an explanatory diagram showing an example of an enlarged image. A two-dimensional code image 41 shown in FIG. 2 is a normal size two-dimensional code image. On the other hand, the enlarged image 42 is a two-dimensional code image enlarged from the normal size to the full short side of the display screen size of the display unit 24.

  When the detection unit 32 detects the carrier wave from the RFID reading unit 12 in the state where the presence of the two-dimensional code image on the display screen is identified, the control unit 33 displays the enlarged image 42 being stored in the RAM 28B. The screen is displayed on the unit 24.

  Next, the operation of the information reading system 1 of this embodiment will be described. FIG. 3 is an explanatory diagram illustrating an example of a two-dimensional code reading operation. For example, the user of the mobile terminal 3 acquires a two-dimensional code image in which passenger information is recorded from an airline site, and performs a boarding procedure using the acquired two-dimensional code image. When the presence of the two-dimensional code image in the display screen is identified, the portable terminal 3 generates an enlarged image 42 in which the two-dimensional code image 41 is enlarged, and stores the enlarged image 42 in the RAM 28B.

  The RFID reader 12 of the reader 2 shown in FIG. 3A transmits the carrier wave X from the vicinity of the reading area 2A. The portable terminal 3 detects the carrier wave X from the reader 2 by approaching the reading area 2 </ b> A of the reader 2 with the two-dimensional code image displayed on the display unit 24. When the mobile terminal 3 detects the carrier wave X from the reader 2, the mobile terminal 3 displays the enlarged image 42 being stored in the RAM 28 </ b> B on the screen of the display unit 24. The reader 2 shown in FIG. 3B has a two-dimensional code before the portable terminal 3 enters the RFID reading range Y and reads information from the RFID tag 26 in the RFID communication range in the reading area 2A. The enlarged image 42 is recognized through the reading unit 11. The reader 2 reads the passenger information of the enlarged image that has been image-recognized.

  FIG. 4 is a flowchart showing an example of the processing operation of the processor 29 of the mobile terminal 3 related to the display control process. The display control process shown in FIG. 4 is a process for displaying an enlarged two-dimensional code image on the display screen when the carrier wave X is detected from the reader 2 in a state where the two-dimensional code image is displayed.

  In FIG. 4, the processor 29 of the portable terminal 3 determines whether or not the display screen of the display unit 24 is lit (step S11). When the display screen is lit (Yes at Step S11), the processor 29 determines whether or not a screen operation is detected (Step S12). When the screen unit is detected (Yes at Step S12), the identification unit 31 in the processor 29 determines whether or not the two-dimensional code image 41 exists in the display screen (Step S13).

  When the two-dimensional code image 41 exists in the display screen (Yes at Step S13), the control unit 33 in the processor 29 enlarges the two-dimensional code image 41 to the display screen size of the display unit 24. 42 is generated (step S14). The control unit 33 stores the generated enlarged image 42 in the RAM 28B (step S15). At this time, the control unit 33 is in a state where the two-dimensional code image 41 is still displayed on the display screen.

  The processor 29 determines whether a screen operation is detected (step S16). When the screen operation is not detected (No at Step S16), the detection unit 32 in the processor 29 determines whether or not the carrier wave X from the RFID reading unit 12 of the reader 2 is detected (Step S17).

  When detecting the carrier wave X (Yes at Step S17), the control unit 33 displays the enlarged image 42 being stored in the RAM 28B on the display screen (Step S18), and ends the processing operation shown in FIG. As a result, the reader 2 recognizes the enlarged image 42 from the two-dimensional code reader 11 and recognizes information in the two-dimensional code image 41 before the RFID tag 26 is recognized after the portable terminal 3 enters the reading area 2A. Read. Then, the reader 2 controls the output unit 13 based on the reading result.

  When the display screen is not lit (No at Step S11) or when no screen operation is detected (No at Step S12), the processor 29 ends the processing operation illustrated in FIG.

  When the two-dimensional code image does not exist in the display screen (No at Step S13), the control unit 33 clears the stored image in the RAM 28B (Step S19) and determines whether the screen operation is detected. The process proceeds to step S16. That is, the control unit 33 stores the enlarged image 42 in the RAM 28B while the two-dimensional code image 41 is being displayed on the display unit 21.

  If the processor 29 detects a screen operation (Yes at Step S16) or does not detect a carrier wave from the RFID reader 12 (No at Step S17), does the two-dimensional code image 41 exist in the display screen? To determine whether or not, the process proceeds to step S13.

  The processor 29 shown in FIG. 4 generates an enlarged image 42 obtained by enlarging the two-dimensional code image 41 when the two-dimensional code image 41 exists on the display screen of the mobile terminal 3, and the generated enlarged image 42 is stored in the RAM 28B. Save in. Then, when the two-dimensional code image 41 exists on the display screen and the carrier wave X is detected from the RFID reading unit 12, the processor 29 displays the enlarged image 42 stored in the RAM 28 </ b> B on the display unit 24. As a result, the reader 2 recognizes the enlarged image 42 before reading the information of the RFID tag 26 of the portable terminal 3 of the RFID reading unit 12 after the portable terminal 3 displaying the two-dimensional code image enters the reading area 2A. Then, information is read from the two-dimensional code image. And the user of the portable terminal 3 reads a two-dimensional code image preferentially.

  The portable terminal 3 of the embodiment enlarges the two-dimensional code image 41 when the two-dimensional code image 41 exists on the display screen, and stores the enlarged image 42 in the RAM 28B. Furthermore, when the two-dimensional code image 41 exists on the display screen and the carrier wave X is detected from the RFID reading unit 12, the portable terminal 3 displays the enlarged image 42 stored in the RAM 28B on the display screen. As a result, the reader 2 facilitates image recognition for the enlarged image 42 after the portable terminal 3 enters the reading area 2A and before reading the information of the RFID tag 26 of the portable terminal 3 of the RFID reading unit 12. The information of the dimension code image is preferentially read easily.

  Note that the mobile terminal 3 of the above embodiment stores the enlarged image 42 in the RAM 28B during the display of the two-dimensional code image 41, and when the carrier wave X is detected, the stored enlarged image 42 is displayed on the display unit 24. indicate. However, the mobile terminal 3 does not store the enlarged image 42 in advance, but enlarges the two-dimensional code image 41 being displayed and displays it on the display unit 24 when the carrier wave X is detected. May be.

  In the above embodiment, for example, a mobile phone or a smartphone is assumed as the mobile terminal 3, and the enlarged image 42 is generated according to the screen size of the display screen of the display unit 24. However, when the mobile terminal is a tablet terminal, the screen size of the display screen is larger than that of the display unit 24 of the mobile terminal 3. FIG. 5 is an explanatory diagram illustrating an example of an enlarged image according to another embodiment. When the two-dimensional code image 41 is present on the display screen as shown in FIG. 5A, the processor of the tablet terminal enlarges the two-dimensional code image 41 and shows it in FIG. 5B. Thus, the enlarged image 42 that can be read by the reader 2 is generated. Further, the processor of the tablet terminal displays a plurality of enlarged images 42 that can be displayed according to the screen size of the display screen of the tablet terminal as shown in FIG. Are stored in the RAM 28B.

  When the carrier 29 from the reader 2 is detected, the processor 29 displays the six enlarged images 42 stored in the RAM 28B on the display screen of the tablet terminal as shown in FIG. As a result, since the tablet terminal displays a plurality of enlarged images 42 on a wide display screen, the reader 2 only needs to be able to recognize one of the plurality of enlarged images. The image can be read more easily.

  In the above embodiment, the two-dimensional code is exemplified, but the present invention is not limited to the two-dimensional code, and can be applied to an identification information image such as a one-dimensional code or a three-dimensional code. Furthermore, in the above embodiment, an RFID tag is illustrated, but the present invention is not limited to the RFID method, and is also applicable to a tag using a method such as near field communication (NFC) or infrared communication. Is possible.

  In addition, each component of each part illustrated does not necessarily need to be physically configured as illustrated. In other words, the specific form of distribution / integration of each part is not limited to the one shown in the figure, and all or a part thereof may be functionally or physically distributed / integrated in arbitrary units according to various loads and usage conditions. Can be configured.

  Furthermore, various processing functions performed in each device are performed on a CPU (Central Processing Unit) (or a microcomputer such as an MPU (Micro Processing Unit), MCU (Micro Controller Unit), etc.) in whole or in part. You may make it perform. Various processing functions may be executed entirely or arbitrarily on a program that is analyzed and executed by a CPU (or a microcomputer such as an MPU or MCU) or hardware based on wired logic. Needless to say.

  By the way, the various processes described in the present embodiment can be realized by causing a program prepared in advance to be executed by a processor such as a CPU in the terminal device. Therefore, in the following, an example of a terminal device that executes a program having the same function as the above embodiment will be described. FIG. 6 is an explanatory diagram illustrating an example of a terminal device that executes a display control program.

  The terminal device 100 that executes the display control program shown in FIG. 6 includes a display unit 110, a short-range communication unit 120, a ROM 130, a RAM 140, a CPU 150, and a wireless tag 160. Further, the display unit 110, the short-range communication unit 120, the ROM 130, the RAM 140, the CPU 150, and the wireless tag 160 are connected via a bus 170. The display unit 110 displays an identification information image such as a two-dimensional code, for example.

  The ROM 130 stores in advance a display control program that exhibits the same function as in the above embodiment. The ROM 130 stores an identification program 130A, a detection program 130B, and a control program 130C as display control programs. Note that the display control program may be recorded on a computer-readable recording medium with a drive (not shown) instead of the ROM 130. The recording medium may be, for example, a portable recording medium such as a CD-ROM, a DVD disk, or a USB memory, or a semiconductor memory such as a flash memory.

  The CPU 150 reads the identification program 130A from the ROM 130 and functions as the identification process 150A. Furthermore, the CPU 150 reads the detection program 130B from the ROM 130 and functions as the detection process 150B. The CPU 150 reads the control program 130C from the ROM 130 and functions as the control process 150C.

  CPU 150 identifies the identification information image being displayed on the display screen of display unit 110. When the identification information image is identified, the CPU 150 detects a signal for reading the RFID tag using a short-range communication unit 120 from a reader (not shown). Furthermore, when a signal is detected, the CPU 150 displays an enlarged identification information image obtained by enlarging the identification information image being displayed on the display unit 110. As a result, even when the reading area where the identification information image and the information of the wireless tag can be read is provided in the vicinity, the information of the identification information image can be preferentially read before reading the information of the wireless tag.
