FIG. 1 is a block diagram showing a schematic configuration of smartphone 100 according to an embodiment of the present application.

As shown in the figure, the smartphone 100 of this embodiment includes a CPU 101 that controls the smartphone 100 as a whole. The CPU 101 includes a touch panel 102 (an example of a "display"), an operator 103, various sensors 104, a memory 105, a timer 106, a voice input interface (I/F) 107, a communication interface (I/F) 110, and a sound system 108. and a camera 109 are connected.

The touch panel 102 has both a function as a display device and a function as an input device, like those provided in general smartphones. When the user designates a position on the display screen, the position information (coordinates) is transmitted from the touch panel 102 to the CPU 101 . The CPU 101 performs processing (including non-processing) according to the position information. Display contents are displayed on the display screen in addition to a plurality of icons for instructing operations of various functions. The display contents are, for example, an index page of an electronic merchandise catalog shown in FIG. 5(a) and an electronic design drawing shown in FIG. 5(b), but these are only examples. However, the display content must contain some encoded code.

The operator 103 is not an icon or button (generated and displayed by software) displayed on the touch panel 102 but a hardware switch (formed by hardware). Typical examples thereof include a power switch and a reset switch (both not shown).

The various sensors 104 include geomagnetic sensors, GPS, acceleration sensors, ultrasonic sensors, optical sensors that detect infrared rays or visible light, and the like.

The memory 105 stores a control program and various application programs executed by the CPU 101, a ROM for storing various data including image data used for screen display and voice data used for pronunciation by each program, and the image data. and a RAM for temporarily storing various data including voice data, various input information, calculation results, and the like. In this embodiment, a rewritable non-volatile ROM, specifically a flash memory, is used so that the control program, various application programs, and various data can be added, deleted, or updated as appropriate. are doing.

A timer 106 measures an interrupt time and various times in timer interrupt processing.

A voice input I/F 107 connects a microphone (hereinafter abbreviated as “microphone”) 111, and converts ambient analog voice signals (typically, voice pronounced by a user) input via the microphone 111 into digital voice signals. (audio data) and stored in a buffer (not shown).

The communication I/F 110 connects the smartphone 100 to a communication network 200 such as the Internet, and communicates with other devices connected to the communication network 200, such as a management server 310 and a number of web servers 320n (n=1) in this embodiment. , 2, . . . ). Addition, deletion, or update of the above programs may be performed via the management server 310 . In this case, communication I/F 110 is used to download various programs and various data from management server 310 . Smartphone 100 serving as a client transmits a command requesting download of a program or data to management server 310 via communication I/F 110 and communication network 200 . Management server 310 receives this command and distributes the requested program and data to smartphone 100 via communication network 200, and smartphone 100 receives these programs and data via communication I/F 110. The download is completed by storing in (the flash memory of) memory 105 .

The sound system 108 is composed of, for example, a DAC, an amplifier, speakers, and the like. The sound system 108 converts a voice signal produced by the other party of the call and input via the communication network 200 and the communication I/F 110 into sound. In this case, it goes without saying that the smartphone or telephone of the other party is connected to the communication network 200 . The sound system 108 also converts musical tone signals generated while the CPU 101 is executing the control program and various application programs into sound. In this embodiment, the tone signal is generated by a so-called software tone generator that is generated by the CPU 101 executing a tone generator program. Of course, a hardware tone generator may be used instead of generating a musical tone signal using a software tone generator, or a tone generator partly composed of hardware and the rest composed of software may be used.

In this embodiment, the smart phone 100 is used as the information processing terminal, but the information processing terminal is not limited to this, and may be a tablet terminal, a portable notebook PC, a PDA (personal digital assistant), or the like.

Control processing executed by smartphone 100 configured as described above will be described in detail with reference to FIGS. 2 to 7. FIG. Hereinafter, in the explanation of the procedure of each process, the step is written as "S".

FIG. 2 shows the procedure of the encoded code recognition process executed by the smartphone 100, especially the CPU 101. As shown in FIG. This encoded code recognition processing is performed when the user of smartphone 100 desires to decode any encoded code from image data containing encoded codes (hereinafter referred to as “encoded code-containing image data”). is started when an application program (hereinafter abbreviated as "application") that realizes Henceforth, in description of each process, a step is described with "S".

In FIG. 2, the CPU 101 first acquires encoded code-containing image data (S10). Here, there are several possible modes of acquiring the encoded code-containing image data. For example, a mode is conceivable in which a physical medium containing an encoded code is captured by the camera 109 and acquired. In this mode, the user points the camera 109 at the physical medium, which is the subject, and operates the shutter (not shown) to acquire the desired encoded code-containing image data. Moreover, as another aspect, it is conceivable to acquire already existing encoded code-containing image data. For example, when the target encoded code-containing image data is stored in the management server 310 or the Web server 320n, the CPU 101 accesses the storage location and reads the encoded code-containing image data stored in the storage location. Download and acquire image data. If the storage location is embedded in, for example, a QR code (registered trademark), the CPU 101 may decode and acquire the QR code (registered trademark) captured by the user with the camera 109, for example. Further, when the encoded code-containing image data is stored in the memory 105, it may be read out from the memory 105 and acquired. The index page of the electronic product catalog shown in FIG. 5A and the electronic design drawing shown in FIG.

Next, the CPU 101 causes the touch panel 102 to display the acquired encoded code-containing image data (S12). Then, CPU 101 waits until touch panel 102 is tapped (an example of an “instruction operation”) (S14: NO), and when touch panel 102 is tapped (S14: YES), CPU 101 advances the process to S16.

In S16, the CPU 101 sets a chord detection range centered on the tap position. When the process proceeds to S16 for the first time after the encoded code recognition process is started, the CPU 101 sets a default value as the code detection range. The default value may be determined in advance according to the size of the encoded code to be decoded. Assuming that it is an encoded code, it may be determined according to the size of the encoded code.

Next, the CPU 101 determines whether or not there is an encoded code within the set code detection range (S18). FIG. 6 includes an example when there is an encoded code in the code detection range. Here, as an encoded code, the two-dimensional code described in Patent Document 1 is taken as an example. This two-dimensional code is hereinafter referred to as "S code". In addition, in Patent Document 1, a plurality of types of S codes are proposed, and in this embodiment, S code 1 shown in FIG. 7 is used. Before describing the processing after S18 with reference to FIG. 6, the configuration of S code 1 will be briefly described with reference to FIG.

In FIG. 7, S code 1 is a code including a data matrix 12 consisting of 100 data cells 12c of 10 rows×10 columns, and is formed on a rectangular plane 10. FIG. First to fourth corner cells 10a to 10d are provided at four corners of the rectangular plane 10, respectively. The first corner cell 10a is painted black in a triangular shape, indicating that the S code 1 is of a type having a data matrix 12 consisting of 10×10 data cells 12c. On the other hand, the second to fourth corner cells 10b to 10d are all painted in black in a rectangular shape to indicate the position where the S code 1 exists.

The data matrix 12 is formed in a rectangular shape within the rectangular plane 10, each row 12r having ten data cells 12c and each column 12l also having ten data cells 12c. Each data cell 12c is also formed in a rectangular shape and painted with either black or white.

The first column in the data matrix 12, that is, the region R1, has the role of defining the division mode of the data matrix 12 excluding the first column and the type of code assigned to the data matrix 12. FIG. If, for example, the data cell (1, 1) in the first row among the data cells included in the region R1 is a black data cell, the data matrix 12 excluding the region R1 is divided into three regions R11 to R13. and that the two-dimensional code 1 is a type of code that identifies the location of data stored in the web server 320n. Region R11 includes 10×4 data cells 12c, region R12 includes 5×5 data cells 12c, and region R13 includes 5×5 data cells 12c. The code assigned to the area R11 indicates the URL of the Web server 320n, the code assigned to the area R12 indicates the directory name in which the data stored in the Web server 320n exists, and the code assigned to the area R13 is , indicates the display file name of the data. However, the codes assigned to R11 to R13 do not directly indicate the URL, directory name and display file name, but indirectly indicate the URL, directory name and display file name. In other words, the codes assigned to R11 to R13 are N-adic numbers, whereas the URL, directory name and display file name are not N-adic numbers. However, the codes assigned to R11 to R13 are associated one-to-one with the above URL, directory name, and display file name. , and the management server 310 acquires the corresponding URL, directory name, and display file name from the received decoding result, and transmits them to the Web server 320n, the CPU 101 acquires the target image data from the Web server 320n. be able to.

FIG. 6 includes an example when there is an encoded code in the code detection range as described above. In FIG. 6, the position indicated by "+" indicates the user's tap position, and the circle around the tap position indicates the chord detection range. Then, the tap position TP1 and the code detection range A1 show an example when the process proceeds to S18 for the first time after the start of the encoded code recognition process. It shows an example when the process proceeds to S18 for the second time after the start.

Returning to FIG. 2, if the user taps the tap position TP1 in FIG. 6 when the process proceeds to S18, the CPU 101 determines that there is an encoded code within the set code detection range A1 ( S18: YES), a decoding target code determination process is executed (S20).

FIG. 3 shows a detailed procedure of decoding target code determination processing. In FIG. 3, the CPU 101 first eliminates codes that cannot be decoded (S50). A code that cannot be decoded means a code in which at least some of the first to fourth corner cells 10a to 10d are not within the code detection range. Such code cannot be recognized as S code 1 and must be eliminated. In the code detection range A1 shown in FIG. 6, S code 1b and S code 1e are excluded as undecodable codes.

Returning to FIG. 3, the CPU 101 then determines whether or not multiple decodable codes are detected (S52). In the code detection range A1 shown in FIG. 6, the decodable code is only the S code 1a, so the CPU 101 determines "NO" in S52 and advances the process to S60. In S60, CPU 101 determines whether or not there is one decodable code. Since there is only one decodable code, the S code 1a, the CPU 101 determines "YES" in S60 and terminates the decoding target code determination process.

Returning to FIG. 2, the CPU 101 determines whether or not the code to be decoded has been determined (S22). Since the S code 1a is determined as the decoding target code, the CPU 101 determines "YES" in S22, decodes the S code 1a determined as the decoding target code, and transmits the decoding result to the management server 310. After that (S24), the encoded code recognition process is terminated.

On the other hand, if there is no encoded code in the set code detection range in the determination of S18 (S18: NO), the CPU 101 executes code detection range change processing (S30). For example, if the user taps the tap position TP2 in FIG. 6, there is no decodable code within the code detection range A1 centered on the tap position TP2. In this case, the CPU 101 determines "NO" in S18.

FIG. 4 shows a detailed procedure of code detection range variation processing. In FIG. 4, the CPU 101 first expands the chord detection range by one step (S70). A code detection range A2 in FIG. 6 shows an example of a code detection range expanded by one step from the code detection range A1.

Next, the CPU 101 increments a variation count counter for counting how many times the chord detection range has been expanded by "1" (S72), and then terminates the chord detection range variation processing. Note that the fluctuation number counter may be composed of, for example, a software counter that counts up a counter area (not shown) secured on the memory 105 .

Returning to FIG. 2, the CPU 101 determines whether or not the count value of the fluctuation number counter exceeds a predetermined number of times (for example, three times) (S32). NO), the CPU 101 returns the process to S16. In S16, the CPU 101 sets the enlarged chord detection range while keeping the tap position as it is. In subsequent S18, the CPU 101 determines whether or not there is a code within the set code detection range.

Now, assuming that the chord detection range for the tap position TP2 is the chord detection range A2 as shown in FIG. Then, the CPU 101 advances the process to the decoding target code determination process (S20), and eliminates codes that cannot be decoded (S50). After removing the undecodable codes, two S codes 1f and 1g are detected as decodable codes in the code detection range A2. Therefore, the CPU 101 determines "YES" in S52 and advances the process to S54.

In S54, the CPU 101 narrows down the code to be decoded to one according to a preset rule. where the rule is, for example,
(R1) The code closest to the tap position is set as the code to be decoded;
(R2) If there are multiple codes at the same distance from the tapped position, notify the user and prompt the user to tap again;
can be considered.

As described above, there are two S codes 1f and S code 1g in the chord detection range A2 of FIG. R2) is applied, the user is notified to that effect, and the user is prompted to tap again. On the other hand, unlike the example of FIG. 6, if the distance from the tap position TP2 is closer to the S code 1f than to the S code 1g, the CPU 101 applies the rule (R1) and converts the S code 1f to the code to be decoded. and In this way, when multiple codes are included in the code detection range, the code to be decoded is narrowed down to one. Then, the CPU 101 determines the narrowed down code as the code to be decoded (S56). After that, the CPU 101 terminates the decoding target code determination process.

When the decoding target code determination process ends, the CPU 101 advances the process to S22 (FIG. 2). Assuming that the S code 1f is determined as the code to be decoded, the CPU 101 determines "YES" in S22, decodes the S code 1f, and transmits the decoding result to the management server 310 (S24). End the encoded code recognition process.

On the other hand, in the determination of S32, if the count value of the fluctuation number counter>predetermined number of times (S32: YES), the CPU 101 advances the process to S40. In S40, the CPU 101 reports an error. In this case, even if the code detection range is expanded multiple times (for example, three times), no code is included in the code detection range. It is conceivable to display on the touch panel 102 prompting the user to tap another tap position. Of course, as long as the user can know the content of the error, the notification mode is not limited to display, and other modes such as voice may be adopted. After finishing the process of S40, the CPU 101 finishes the encoded code recognition process.

A chord detection range A3 centered on the tap position TP3 in FIG. 6 indicates a chord detection range after the CPU 101 executes the process of S70 (FIG. 4) three times, for example. Since the code detection range A3 includes the S code 1h, the CPU 101 determines "YES" in S18 and advances the process to the decoding target code determination process of S20. However, in the decoding target code determination process, the CPU 101 determines "NO" in S60 and determines that there is no decodable code (S62). Thereafter, when the process proceeds to S22, the CPU 101 determines "NO" in S22, and proceeds to S40. The contents of the error may be the same as those described above.

In the present embodiment, when the touch panel 102 is tapped, the chord detection range centering on the tapped position is immediately set (see S14 and S16 in FIG. 2). If there is no S code 1 at the tap position, the code detection range may be set. In this case, when the entire S code 1 is not tapped, for example, when only part of the S code 1 is tapped, the chord detection range is gradually expanded around the tap position, and the S code 1 is tapped. When the entire code is included, the expansion may be stopped and the S code 1 within the code detection range may be determined as the code to be decoded.

As described above, the smartphone 100 of the present embodiment is an information processing terminal including the touch panel 102 and the CPU 101. The CPU 101 performs display processing for displaying image data including the S code 1 on the touch panel 102. , a touch position detection process for detecting a touch position touched by the user on the image data displayed on the touch panel 102, and a judgment as to whether or not the touch position detected by the touch position detection process has an S code of 1. and a decoding process for decoding the encoded code when it is determined that there is an S code 1 by the determination process.

As described above, in the smartphone 100 of the present embodiment, the user can decode the S code 1 simply by touching the S code 1 included in the image displayed on the touch panel 102 . Even when a plurality of S codes 1 are densely displayed in the image displayed in , it is possible to easily select and decode the S code 1 to be decoded.

Incidentally, in the present embodiment, the touch panel 102 is an example of a "display". The CPU 101 is an example of a "controller". S code 1 is an example of "encoding code". A touch is an example of an “instruction operation”.

Further, the CPU 101 is characterized by further executing a transmission process of transmitting the decoding result of the decoding process to the management server 310 external to the smartphone 100 via the communication I/F 110 provided in the smartphone 100 . Incidentally, the management server 310 is an example of a "server computer".

This is convenient because the decoding result is automatically sent to the external management server 310 .

Further, the CPU 101 further executes a setting process for setting a predetermined range on the image including the touch position detected by the touch position detection process as the chord detection range A1. It is characterized by judging whether or not there is an S code 1 within the range A1.

As a result, the S code 1 can be detected even if the user does not accurately touch the S code 1 intended for decoding.

Further, when it is determined that a plurality of S codes 1 are included in the code detection range A2 set by the determination processing, the CPU 101 selects one of the plurality of S codes 1 as a predetermined encoded code. is further executed to determine the code to be decoded according to the selection rule of (1), and in the decoding process, the code to be decoded determined by the determination process is decoded.

As a result, even when a plurality of S codes 1 are densely displayed in the image displayed on the touch panel 102, it is possible to automatically select and decode the S code 1 for decoding purposes. Become.

Further, when the CPU 101 fails to select any one S code 1 from a plurality of S codes 1 by the decision processing, the CPU 101 notifies the user to prompt the user to touch the image displayed on the touch panel 102 again. Processing is further performed.

As a result, when a plurality of S codes 1 are densely displayed in the image displayed on the touch panel 102, it is possible to prevent the S code 1 not intended for decoding from being inadvertently selected and decoded. It becomes possible.

Further, when it is determined that the S code 1 does not exist within the set chord detection range, the CPU 101 further executes enlargement processing for enlarging the set chord detection range. It is characterized by determining whether or not there is an S code 1 within the code detection range expanded by the processing.

As a result, even if the user touches the S-code 1 without the S-code 1 intended for decoding, the S-code 1 can be detected.

Further, when it is determined by the determination processing that a plurality of S codes 1 are included in the expanded code detection range, the CPU 101 selects one encoded code from the plurality of S codes 1 as a predetermined code. selecting according to a selection rule and determining a code to be decoded; and decoding the code to be decoded determined by the determination process.

As a result, even when a plurality of S codes 1 are displayed within the expanded code detection range, it is possible to automatically select and decode the encoded code for the purpose of decoding from among them. .

Further, when it is determined by the determination processing that the S code 1 does not exist within the chord detection range enlarged by the enlargement processing, the CPU 101 executes the enlargement processing again, and performs determination processing on the chord detection range that has been enlarged again. When it is determined that there is no S code 1 within the code detection range expanded a predetermined number of times by the determination processing after repeating the control processing of executing the control processing a predetermined number of times, a message is displayed on the touch panel 102 to the user. The present invention is characterized in that the notification is made so as to prompt the user to touch the image again.

In this way, even if the code detection range is expanded several times, if the encoded code is not included, the user is urged to redo the instruction operation, thereby preventing excessive expansion of the code detection range. It becomes possible.

Also, the predetermined selection rule is characterized in that the S code 1 whose position on the image is closest to the touch position is selected.

As a result, it is possible to select the S code 1 as intended by the user and determine it as the code to be decoded.

It should be noted that the present invention is not limited to the above embodiments, and various modifications can be made without departing from the spirit of the present invention.

(1) In the above embodiment, the S code was used as an example of the encoded code. Alternatively, the code is not limited to a two-dimensional code, and may be a one-dimensional code such as a bar code.
