FIG. 3 is a block diagram showing the configuration of main parts of the mobile terminal 2 according to this example. FIG. 4A is an explanatory diagram showing a usage example of the mobile terminal 2 when the user is looking at the screen 200. FIG. FIG. 4B is an explanatory diagram showing a usage example of the mobile terminal 2 when the user holds the screen 200 over the reading area 320. As shown in FIG. An arrow X11 shown in FIG. 4A and an arrow X12 shown in FIG. 4B indicate the direction of the screen 200. In FIG. An arrow X13 shown in FIGS. 4A and 4B indicates the vertical direction.

The mobile terminal 2 is, for example, a smartphone, and as shown in FIG. It has

The control unit 21 controls operations of each unit including the operation unit 22 , the detection unit 23 , the display unit 24 , the image generation unit 25 and the wireless communication unit 26 .

The operation unit 22 has a touch panel attached on the screen 200 of the display device 20 provided on the main body of the mobile terminal 2, and detects user operations on the touch panel (see FIG. 4A). The operation unit 22 receives, for example, an entry station, an exit station, an input of a ticket type, or an instruction to display the optical reading code 10 by the user.

The detector 23 detects the orientation of the screen 200 of the display 20 . The detection unit 23 has, for example, a gyro sensor, and detects a change in orientation of the screen 200 of the display 20 based on the output value of the gyro sensor. For example, when the user is viewing the screen 200, the direction of the screen 200 of the mobile terminal 2 is the direction of the arrow X11 as shown in FIG. 4A. Further, for example, when the user holds the mobile terminal 2 over the reading area 320 of the automatic ticket gate 3, the screen 200 of the mobile terminal 2 is oriented in the direction of the arrow X12 as shown in FIG. 4B. The gyro sensor detects a change in the direction of the arrow X11 shown in FIG. 4A on the screen 200 to the direction of the arrow X12 shown in FIG. 4B. Also, the gyro sensor detects a change in the direction of arrow X12 shown in FIG. 4B to the direction of arrow X11 shown in FIG. 4A.

When the gyro sensor detects the change in the orientation of the screen 200, the detection unit 23 detects that the orientation of the screen 200 changes from the arrow X11 to the arrow X12, and then the orientation of the screen 200 changes from the arrow X12 to the arrow X11. Until then, it is detected that the direction of the screen 200 is the direction of the arrow X12. In other words, if the detection unit 23 does not detect that the orientation of the screen 200 changes from the arrow X12 to the arrow X11 after the orientation of the screen 200 has changed from the arrow X11 to the arrow X12, the orientation of the screen 200 is not changed from the arrow X12 to the arrow X11. It is the direction of X12. In other words, if the detection unit 23 detects that the orientation of the screen 200 has changed from the arrow X11 to the arrow X12 and does not detect that the orientation of the screen 200 has changed from the arrow X12 to the arrow X11, the detection unit 23 , the direction of the screen 200 facing the reading area 320 is detected. In other words, if the detection unit 23 detects that the orientation of the screen 200 has changed from the arrow X11 to the arrow X12 and does not detect that the orientation of the screen 200 has changed from the arrow X12 to the arrow X11, the user cannot , the screen 200 is held over the reading area 320 of the automatic ticket gate 3 .

The display unit 24 displays the image generated by the image generation unit 25 on the screen 200 of the display device 20 .

Also, the display unit 24 changes the brightness of the screen 200 according to the orientation of the screen 200 . More specifically, the display unit 24 increases the brightness of the screen 200 when the surrounding brightness becomes weak. The display unit 24 has, for example, a brightness sensor that detects ambient brightness. When the user holds the screen 200 of the portable terminal 2 over the reading area 320, the screen 200 faces the reading area 320, so the brightness sensor of the display unit 24 detects that the ambient brightness is relatively low. In this case, the display unit 24 can display the optical read code 10 more clearly by increasing the brightness of the screen 200 that displays the image generated by the image generation unit 25 .

The image generator 25 generates an image displaying the optical read code 10 to be read by the automatic ticket gate 3 . While the detection unit 23 detects that the screen 200 of the display 20 faces the reading area 320 of the automatic ticket gate 3, the image generation unit 25 generates an optical reading code as time changes. An image is generated in which the ten display positions are arranged at different positions.

FIG. 5A is an explanatory diagram showing an example of an image displaying the optical read code 10. FIG. FIG. 5B is an image displaying the optical read code 10, and is an explanatory diagram showing an example different from that in FIG. 5A.

The image generator 25 generates an image in which the optical read code 10 is arranged in the center of the screen 200 so that the user can easily check the optical read code 10 on the screen 200, as shown in FIG. 5A. In other words, as shown in FIG. 4A, when the user is viewing the screen 200, the image generator 25 generates an image in which the optical reading code 10 is placed in the center of the screen 200. FIG. In the following description, the image in which the optical reading code 10 is arranged in the center of the screen 200 is assumed to be the initial image.

The image generation unit 25 detects that the direction of the screen 200 is the arrow X12 (see FIG. 4B) by the detection unit 23, and after a desired time has passed, the image generation unit 25 reads the optically read code 10 as shown in FIG. 5B. , an image arranged in one direction on the screen 200 is generated.

Note that the image generation unit 25 generates the initial image when the detection unit 23 detects that the orientation of the screen 200 has changed from the arrow X12 (see FIG. 4B) to the arrow X11 (see FIG. 4A).

Further, the image generator 25 generates an image such that the position of the optical reading code 10 on the screen 200 randomly and repeatedly changes while the user holds the screen 200 over the reading area 320 of the automatic ticket gate 3. Generate. For example, while the user holds the screen 200 over the reading area 320 of the automatic ticket gate 3, the control section 21 repeatedly generates random numbers, and the image generating section 25 places the optical reading code 10 at the position corresponding to the random number. to generate an image in which That is, while the user holds the screen 200 over the reading area 320 of the automatic ticket gate 3, the image generator 25 repeatedly generates an image different from the previously generated image.

The wireless communication unit 26 performs, for example, telephone communication via a mobile phone network and data communication with a server or the like on the Internet.

In the mobile terminal 2 according to this example, while the detection unit 23 detects that the orientation of the screen 200 is the arrow X12 shown in FIG. Repeatedly generate the placed image. As a result, the automatic ticket gate 3 according to this example automatically moves the position of the optical reading code 10, so even if the user cannot hold up the screen 200 at an appropriate reading position, the user can The optical reading code 10 can be read without looking up the screen 200 again. As a result, the mobile terminal 2 and the ticket gate system 1 according to this example can suppress an increase in the time required to read the optical reading code 10 . As a result, the mobile terminal 2 and the ticket examination system 1 according to this example can suppress a decrease in the throughput of ticket examination processing.

The control unit 21 of the mobile terminal 2 is composed of a hardware CPU, memory, and other electronic circuits. The hardware CPU operates the detection unit 23, the display unit 24, and the image generation unit 25 when executing the information processing program according to the present invention. The memory also has an area for developing the information processing program according to the present invention and an area for temporarily storing data generated when the information processing program is executed. The control unit 21 may be an LSI that integrates a hardware CPU, memory, and the like. Also, the hardware CPU is a computer that executes the information processing method according to the present invention.

<3. Operation example>
The operation of the automatic ticket gate 3 according to this example will be described with reference to FIG. FIG. 6 is a flow chart showing an example of ticket examination processing of the automatic ticket examination machine 3 .

The image capturing unit 321 of the reading unit 32 of the automatic ticket gate 3 captures an image displayed on the screen 200 overlaid on the reading area 320 (S11). The image processing unit 322 of the reading unit 32 of the automatic ticket gate 3 decodes the captured image (S12). The reading determination unit 323 of the reading unit 32 of the automatic ticket gate 3 determines whether or not the ticket information obtained by the decoding process has been successfully read (S13). If the reading determination unit 323 fails to read the ticket information (S13: No), the automatic ticket gate 3 returns the process to S11. That is, the automatic ticket gate 3 repeatedly captures the image displayed on the screen 200 of the mobile terminal 2 until the ticket information is successfully read.

If the read determination unit 323 has successfully read the ticket information (S13: Yes), the determination unit 33 of the automatic ticket gate 3 determines whether or not to allow the user to pass based on the ticket information. (S14). In other words, the determination unit 33 determines whether or not the identification number, expiration date, and valid section included in the ticket information are appropriate for the user's passage. If the determination unit 33 permits the user to pass (S14: Yes), the door opening/closing unit 35 opens the door 351 (S15). Then, the communication unit 37 of the automatic ticket gate 3 transmits data in which the identification number included in the ticket information is associated with the entry/exit log to the station server 4 (S16).

If the determination unit 33 does not permit the user to pass (S14: No), the door opening/closing unit 35 closes the door 351 (S17).

The operation of the mobile terminal 2 according to this example will be described with reference to FIG. FIG. 7 is a flowchart showing an example of image display processing of the mobile terminal 2. As shown in FIG.

The image generation unit 25 of the mobile terminal 2 generates an image (initial image) in which the optical reading code 10 is placed in the center of the screen 200 (S21). The display unit 24 of the mobile terminal 2 displays the initial image generated by the image generation unit 25 on the screen 200 (S22). Here, the user can confirm the optical read code 10 displayed on the screen 200 on the screen 200 (see FIG. 4A).

When the user intends to hold the screen 200 over the reading area 320 of the automatic ticket gate 3, the direction of the screen 200 of the mobile terminal 2 is changed from the arrow X11 shown in FIG. 4A to the arrow X12 shown in FIG. 4B. The detection unit 23 of the mobile terminal 2 detects that the orientation of the screen 200 has changed from the arrow X11 to the arrow X12 (S23). In other words, the detection unit 23 detects that the screen 200 faces the reading area 320 . When the detection unit 23 detects that the orientation of the screen 200 has changed from the arrow X11 to the arrow X12 (S23: Yes), the display unit 24 changes the brightness of the screen 200 to a desired value (S24). The mobile terminal 2 determines whether a predetermined time (eg, 50 msec to 100 msec) has passed (S25). After a predetermined period of time has elapsed, the control unit 21 generates random numbers (S26). The image generator 25 generates an image in which the optical reading code 10 is arranged at the position corresponding to the random number (S27). The display unit 24 displays the image generated by the image generation unit 25 on the screen 200 (S28). The detection unit 23 detects that the screen 200 faces the reading area 320 (S29). That is, unless the detection unit 23 detects that the direction of the screen 200 has changed from the arrow X12 to the arrow X11, the user is holding the screen 200 over the reading area 320 . When the detection unit 23 detects that the screen 200 faces the reading area 320 (S29: Yes), the image display process returns to S25.

On the other hand, when the user moves the portable terminal 2 so that the screen 200 is oriented in the direction of the arrow X11, the detection unit 23 detects that the orientation of the screen 200 has changed from the arrow X12 to the arrow X11. When the detection unit 23 detects that the direction of the screen 200 has changed from the arrow X12 to the arrow X11 (S29: No), the image generation unit 25 generates an image ( initial image) is generated (S30). The display unit 24 of the mobile terminal 2 displays the initial image generated by the image generation unit 25 on the screen 200 (S31).

In this way, the portable terminal 2 according to this example displays the position of the optical read code 10 on the screen 200 so that the position of the optical reading code 10 automatically and repeatedly changes until it detects that the orientation of the screen 200 has changed from the arrow X12 to the arrow X11. indicate. Since the portable terminal 2 according to this example displays the optically readable code 10 by randomly moving it on the screen 200 , the user can display the screen so that the optically readable code 10 is positioned at an appropriate position in the reading area 320 . Even when the screen 200 is not held over the reading area 320, the user does not need to hold up the screen 200 again. As a result, the automatic ticket gate 3 according to this example can read the optical reading code 10 without the user holding up the screen 200 again. An increase in the time required to read the code 10 can be suppressed. As a result, in the mobile terminal and ticket examination system 1 according to this example, it is possible to suppress a decrease in the throughput of ticket examination processing.

<4. Variation>
An image generated by the image generator 25 of the portable terminal 2 according to this modification will be described with reference to FIGS. 8A, 8B, 9A and 9B. FIG. 8A is an explanatory diagram showing an example of an image displaying the optical reading code 10. FIG. FIG. 8B is an image displaying the optical read code 10, and is an explanatory diagram showing an example different from that of FIG. 8A. Arrow Y11 shown in FIG. 8A indicates one direction (upward direction) on screen 200 . An arrow Y12 shown in FIG. 8B indicates the opposite direction (downward direction) to the arrow Y11. FIG. 9A is an explanatory diagram showing another image displaying the optical reading code 10 according to the modification. FIG. 9B is another image displaying the optical reading code 10 according to the modification, and is an explanatory diagram showing an example different from FIG. 9A. An arrow Z11 shown in FIG. 9A indicates the left direction on the screen 200. As shown in FIG. An arrow Z12 shown in FIG. 9B indicates the right direction on the screen 200. As shown in FIG.

The image generator 25 according to this modification generates an image in which the optical read code 10 is arranged at a position away from the center of the screen 200 of the display 20 in one direction. Then, the image generator 25 generates an image in which the optical reading code 10 is arranged at a position symmetrical to a position away from the center of the screen 200 of the display 20 in one direction.

For example, as shown in FIG. 8A, the image generator 25 generates an image in which the optical reading code 10 is arranged on the arrow Y11 direction side (upper side). In addition, as shown in FIG. 8B, the image generator 25 generates an image in which the optical reading code 10 is arranged on the arrow Y12 direction side (lower side). Furthermore, as shown in FIG. 9A, the image generator 25 generates an image in which the optical reading code 10 is arranged on the arrow Z11 direction side (left side). In addition, as shown in FIG. 9B, the image generator 25 generates an image in which the optical reading code 10 is arranged on the arrow Z12 direction side (right side).

An example of image display processing of the portable terminal 2 according to this modification will be described with reference to FIG. FIG. 10 is a flowchart showing an example of image display processing of the mobile terminal 2 according to the modification. The processes S41 to S44 and S51 to S52 are the same as the above-described processes S21 to S24 and S30 to S31, so the description thereof will be omitted.

After the image generator 25 changes the luminance (S44), the portable terminal 2 determines whether a predetermined time (eg, 50 msec to 100 msec) has passed (S45). The image generator 25 sets one direction (for example, the direction of the arrow Y11) in which the optical reading code 10 is arranged (S46). The image generator 25 generates an image in which the optical reading code 10 is arranged at a position away from the center of the screen 200 of the display 20 in one direction (the direction of the arrow Y11) (S47). The display unit 24 displays this image (S48) (see FIG. 8A).

The detection unit 23 detects that the screen 200 faces the reading area 320 (S49). When the detection unit 23 detects that the screen 200 faces the reading area 320 (S49: Yes), the image display process returns to S45.

Here, the portable terminal 2 waits for a predetermined time (for example, 50 msec to 100 msec) (S45). In the second and subsequent processes S46, the image generation unit 25 moves the optical read code 10 to a position (direction of arrow Y12) that is symmetrical to the position away from the center of the screen 200 of the display 20 in the direction of arrow Y11. ).

In this way, in processing S46, the image generator 25 changes to a different direction from the previous direction.
