Description

  The present invention relates to a portable terminal having a non-contact IC card function used for a so-called electronic wallet or the like, a non-contact communication method and a program when the portable terminal performs non-contact communication.

  In recent years, so-called non-contact IC cards have advantages such as ease of use for users, excellent durability, simultaneous access to multiple cards, good maintainability, etc. It is spreading as train tickets and prepaid cards, so-called electronic wallets.

  When these non-contact IC cards come close to a dedicated non-contact IC card reader / writer (hereinafter simply referred to as a reader / writer) connected to a network, various data stored therein are written. Erasing, updating, etc. are performed by the reader / writer.

  Recently, a non-contact IC card function is also installed in a portable terminal such as a portable telephone terminal, and electronic payment using the non-contact IC card function of the portable telephone terminal is also becoming common.

  In Japanese Patent Laid-Open No. 2005-354300 (Patent Document 1), a portable terminal having a built-in short-range wireless communication means as a non-contact IC card function is connected to the short-range wireless communication means. Separately from the antenna, a measurement antenna is provided, and the reception status of the radio wave from the reader / writer is measured with the measurement antenna. When the radio wave is received from the reader / writer, the direction in which the reader / writer exists is determined. A technique is disclosed in which a mobile terminal having a built-in non-contact IC card function can communicate with a reader / writer satisfactorily by displaying the determined direction in which the reader / writer exists on a display unit.

Japanese Patent Laying-Open No. 2005-354300 (FIGS. 4, 5, and 6)

  By the way, when a non-contact IC card function is mounted on a mobile terminal such as a mobile phone terminal, the antenna of the non-contact IC card function (hereinafter referred to as an IC card antenna) is generally provided by a case of the mobile terminal. It is provided in any one of the plurality of housing surfaces (hereinafter referred to as an IC card antenna mounting surface).

  On the other hand, the communication characteristics generally differ greatly between the case where the IC card antenna mounting surface is close to the reader / writer and the case surface on the back side of the IC card antenna mounting surface is close to the reader / writer. When the casing surface is brought close to the reader / writer, the communication characteristics are significantly deteriorated.

  Therefore, when performing non-contact communication between the portable terminal and the reader / writer, the user needs to perform an operation to bring the IC card antenna mounting surface side closer to the reader / writer. However, at that time, the user performs an operation of holding the portable terminal over the reader / writer while holding the portable terminal, for example, so that the user can only see the case surface side that is the back side with respect to the IC card antenna mounting surface. There will be no.

  In addition, in the case of a mobile phone terminal or the like, it is not possible to design so that the center position of the IC card antenna on the IC card antenna mounting surface matches the housing center position of the IC card antenna mounting surface due to its structure. Difficult, usually their center positions are different.

  For this reason, in a conventional cellular phone terminal having a non-contact IC card function, the center position of the IC card antenna is referred to as a reader / writer antenna (hereinafter referred to as a reader / writer antenna) as viewed from the user. It has become very difficult to match the center position.

  Here, in the case of performing non-contact communication, if the center position of the IC card antenna and the center position of the reader / writer antenna are deviated, the success rate of communication is lowered. Therefore, in order to increase the success rate of the communication, a position where the center position of the IC card antenna and the center position of the reader / writer antenna are substantially coincided when the IC card antenna mounting surface is held over the reader / writer. Matching operation is required.

  In addition, the non-contact communication is triggered by the detection of the carrier wave from the reader / writer by the mobile terminal, but if the center alignment of both the IC card antenna and the reader / writer antenna is not performed successfully, for example, In the worst case, the IC card antenna fails to detect the carrier wave from the reader / writer, delays the start of communication, or a retry occurs due to communication failure, resulting in a longer communication time (time until completion of communication). Even if a retry is performed, a situation occurs in which communication fails.

  The present invention has been proposed in view of such a situation, and the center positions of the reader / writer and the antenna of the non-contact IC card can be easily, reliably and quickly adjusted by the user, and the non-contact between the reader / writer and the reader / writer can be adjusted. It is an object of the present invention to provide a portable terminal, a non-contact communication control method, and a program capable of reliably executing contact communication and shortening the communication time.

  Also, the non-contact communication control method of the present invention takes a picture of an external space side substantially perpendicular to the antenna mounting surface of the non-contact IC card unit that performs non-contact communication with the camera unit. Based on the offset data corresponding to the distance between the antenna center position of the camera and the lens center position of the camera unit, the position shift is equivalent to the distance between the antenna center position of the non-contact IC card unit and the lens center position of the camera unit. The trimming position for correcting the image is determined, and the user can view the moving image taken by the camera unit when the antenna of the non-contact IC card unit is held over at least the antenna installation surface side of the non-contact IC card reader / writer. An image cut out from a moving image captured by the camera unit according to the trimming position is displayed on the display screen of the display unit that can be displayed. The non-contact communication start control is performed based on the pattern recognition result obtained by performing the pattern recognition of the predetermined mark drawn on the antenna installation surface of the non-contact IC card reader / writer using the image data photographed by the By doing so, the above-described problems are solved.

  In addition, the non-contact communication control program of the present invention includes a step function of photographing the external space side substantially perpendicular to the antenna mounting surface of the non-contact IC card unit that performs non-contact communication, and a non-contact function. Based on the offset data corresponding to the distance between the antenna center position of the contact IC card unit and the lens center position of the camera unit, the distance between the antenna center position of the non-contact IC card unit and the lens center position of the camera unit Function of determining the trimming position for correcting the positional deviation of the minute, and a movie taken by the camera unit when the antenna of the non-contact IC card unit is held at least on the antenna installation surface side of the non-contact IC card reader / writer An image cut out from a moving image shot by the camera unit according to the trimming position on the display screen of the display unit where the user can see the image The function of displaying the mark and the pattern recognition of the predetermined mark drawn on the antenna installation surface of the non-contact IC card reader / writer using the instruction from the user or the image data taken by the camera unit The above-described problem is solved by causing the portable terminal to execute the function of the step of performing the start control of the non-contact communication based on the pattern recognition result.

  That is, according to the present invention, when performing non-contact communication, a predetermined mark or the like drawn on the antenna installation surface of the non-contact IC card reader / writer is photographed by the camera unit, and the photographed image is displayed on the display screen. By displaying the above, the user is shown a target when the center positions of the reader / writer and the antenna of the non-contact IC card are aligned.

  According to the present invention, when performing non-contact communication, a moving image obtained by photographing the antenna installation surface side of the non-contact IC card reader / writer is displayed, whereby the center positions of the reader / writer and the antenna of the non-contact IC card are determined by the user. Therefore, it is possible to easily, surely and quickly adjust, so that non-contact communication with the reader / writer can be reliably performed and the communication time can be shortened.

[Explanation of operation when starting and executing non-contact communication]
When the mobile phone terminal of this embodiment performs contactless communication with a reader / writer, important conditions for the success of the contactless communication and the reduction of the time required for contactless communication are mounted on the mobile phone terminal. The positional relationship between the IC card antenna and the reader / writer antenna.

  FIG. 5 shows a “communicable area” in which the mobile phone terminal and the reader / writer can perform contactless communication, and a “carrier detection area” in which the contactless IC card unit 25 of the mobile phone terminal can detect a carrier wave from the reader / writer. And the “center point (reader / writer center point)” of the reader / writer antenna. The “reader / writer center point” corresponds to the position where the target mark 60 is drawn.

  In FIG. 5, for example, when a mobile phone terminal exists in the “carrier wave detection area”, the non-contact IC card unit 25 of the mobile phone terminal can detect the carrier wave of the reader / writer. However, the success rate of non-contact communication with the reader / writer is not necessarily 100% even when a mobile phone terminal is in the “carrier detection area”. Even if non-contact communication is started within “”, communication may fail. If non-contact communication fails in the “carrier detection area”, a communication retry occurs.

  On the other hand, when the mobile phone terminal exists in the “communication area”, the center position 41 of the IC card antenna 26 of the mobile phone terminal exists in the “communication area” and the “reader / writer”. When it substantially coincides with the position of the target mark, which is the “center point”, the success rate of non-contact communication with the reader / writer is guaranteed to be approximately 100%.

  Therefore, in order to succeed in non-contact communication between the mobile phone terminal and the reader / writer and eliminate the occurrence of communication retry and reduce the time of non-contact communication, the user can use the IC card antenna 26 of the mobile phone terminal. It is necessary to place the center position 41 within the “communicable area” and approximately coincide with the position of the “reader / writer center point (target mark)”.

  On the other hand, when non-contact communication is performed between the mobile phone terminal and the reader / writer, the “reader / writer center point” is due to the presence of the target mark 60 drawn on the antenna installation surface of the reader / writer. Although the position is clear when viewed from the user, the position of the central position 41 of the IC card antenna 26 of the mobile phone terminal is difficult to understand from the user's viewpoint. That is, when non-contact communication is performed between the mobile phone terminal and the reader / writer, the IC card antenna mounting surface 34 is directed to the reader / writer side, so that the user can determine the center position of the IC card antenna 26 from the user. It is not possible to confirm whether 41 is accurately aligned with the “reader / writer center point”.

  For this reason, the mobile phone terminal according to the present embodiment executes the function described below in accordance with the pressing operation of the trigger button 36 by the user, so that the user can determine the center positions of the reader / writer and the IC card antenna. It is possible to easily, surely and quickly match, and it is possible to reliably perform non-contact communication with the reader / writer and to shorten the communication time.

  Here, the mobile phone terminal according to the present embodiment assists the user when aligning the center position 41 of the IC card antenna 26 with the “reader / writer center point”, and waits for an instruction from the user to execute non-contact communication. And a manual mode function for determining whether the center position 41 of the IC card antenna 26 matches the “reader / writer center point”, and automatically executing non-contact communication when the positions match. It has.

[Manual mode]
First, the manual mode will be described.

  In the mobile phone terminal according to the present embodiment, when the trigger button 36 is pressed by the user for a short time (pressing operation for a time shorter than the long time to be described later), the control unit 10 uses this as a trigger for the communication area for the manual mode. The determination program 17 is activated. When the communicable area determination program 17 for the manual mode is activated, the control unit 10 first controls the camera unit 24 to start capturing a real-time moving image and displays the real-time moving image on the sub display 50. To display.

  Here, as described above, the offset 19 corresponding to the distance D exists between the center position 41 of the IC card antenna on the IC card antenna mounting surface 34 and the position of the lens system of the camera module 40. ing. For this reason, the control unit 10 acquires the data of the offset 19 for the distance D from the memory unit 16 prior to the start of shooting of the real-time moving image by the camera unit 24, and based on the data of the offset 19, the camera A trimming position for correcting the positional deviation of the distance D from the real-time moving image by the unit 24 is determined. When shooting of the real-time moving image of the camera unit 24 is started, the control unit 10 cuts out (trims) an image area corresponding to the trimming position from the real-time moving image, and the trimmed moving image is extracted. It is displayed on the sub display 50.

  Next, in the manual mode, the user moves the mobile phone terminal so that the target mark 60 of the reader / writer is approximately at the center of the trimmed image displayed on the sub-display 50, and the target mark The mobile phone terminal is brought close to the reader / writer so that the size of the 60 images is a certain size or more. It should be noted that a predetermined frame image indicating the certain size is displayed in the sub-display 50 as an aid for the user to determine whether or not the size of the image of the target mark 60 has exceeded the certain size. You may do it.

  That is, in the present embodiment, the case where the target mark 60 is located approximately in the center of the trimmed image means that the center position 41 of the IC card antenna 26 is approximately the same as the position of the “reader / writer center point (target mark)”. In addition, when the size of the image of the target mark 60 is a certain size or more, the center position 41 of the IC card antenna 26 is within the “communicable area” of the reader / writer. Is present. FIG. 6 shows an example of an image when the target mark 60 exists in the approximate center of the trimmed image 61, and FIG. 7 shows a case where a part of the target mark 60 is out of the trimmed image 61. An example of the image is shown.

  When the target mark 60 is positioned approximately in the center of the moving image displayed on the sub-display 60 and the size of the image of the target mark 60 exceeds a certain size, the user The trigger button 36 is pressed again. In the manual mode, pattern recognition, which will be described later in the auto mode, is performed, a pattern that substantially matches the target mark is present in the approximate center in the trimmed image, and the size of the pattern is determined in advance. If the size is larger than the predetermined size, a message indicating that the user is requested to start non-contact communication (for example, a message requesting pressing of the trigger button 36) is displayed on the sub-display 50, or a predetermined notification is given. Sound may be output.

  As described above, when the trigger button 36 is pressed again by the user, the control unit 10 starts non-contact communication between the non-contact IC card unit 25 and the reader / writer.

  As described above, according to the present embodiment, in the manual mode, the user moves the position of the mobile phone terminal while viewing the display on the sub-display 50, so that the target mark 60 of the reader / writer and the IC card antenna Can be quickly and easily matched with the center position 41 of the mobile phone, and the mobile phone terminal can be placed in the “communicable area” of the reader / writer. Therefore, according to the mobile phone terminal of the present embodiment, it is possible to reliably perform non-contact communication with the reader / writer and shorten the communication time.

  In the above example, the trigger button 36 is used as a trigger. For example, while the trigger button 36 is kept pressed, the start of the non-contact communication process is put on hold, and the mobile phone terminal After entering the “communicable area”, the contactless communication may be started when the trigger button 36 is released.

〔auto mode〕
Next, the auto mode will be described.

  In the mobile phone terminal according to the present embodiment, when the trigger button 36 is pressed (long-pressed) for a certain time or more by the user, for example, the control unit 10 starts the communicable area determination program 17 for the auto mode using that as a trigger. When the communicable area determination program 17 for the auto mode is activated, the control unit 10 first controls the camera unit 24 to start shooting a real-time moving image and displays the real-time moving image on the sub-display 50. To display.

  Here, the offset 19 corresponding to the distance D exists between the center position 41 of the IC card antenna on the IC card antenna mounting surface 34 and the position of the lens system of the camera module 40. In the same manner as in the manual mode, the control unit 10 acquires the offset 19 data for the distance D from the memory unit 16 before the camera unit 24 starts to capture the real-time moving image, and the offset 19 data. Based on the above, the trimming position for correcting the positional deviation of the distance D is determined from the real-time moving image by the camera unit 24. When shooting of the real-time moving image of the camera unit 24 is started, the control unit 10 cuts out (trims) an image area corresponding to the trimming position from the real-time moving image, and the trimmed moving image is extracted. It is displayed on the sub display 50.

  Next, in the auto mode, the control unit 10 substantially matches the target mark pattern 18 stored in the memory unit 16 in the approximate center of the moving image trimmed in consideration of the offset 19 minutes. Pattern matching is performed so as to detect whether or not a pattern exists. When a pattern that substantially matches the target mark pattern 18 exists at the approximate center in the trimmed image, the size determination is further performed as to whether the pattern size is equal to or larger than a predetermined size. Do.

  That is, in the auto mode, when the pattern that substantially matches the target mark pattern 18 exists at the approximate center in the trimmed image, the center position 41 of the IC card antenna 26 is “the reader / writer center point (target mark ) ", And the center position 41 of the IC card antenna 26 is" communication "of the reader / writer when the pattern size is equal to or larger than a predetermined size. It indicates that it exists in the “possible area”.

  Then, as in the image example of FIG. 6, the control unit 10 has a pattern that substantially matches the target mark pattern 18 in the approximate center in the trimmed image, and the size of the pattern is determined in advance. If it is equal to or larger than the size, the fact is displayed on the sub-display 50 (or a predetermined notification sound is output) to notify the user that non-contact communication is possible and the non-contact The non-contact communication between the IC card unit 25 and the reader / writer is started.

  As a result, according to the mobile phone terminal of the present embodiment, the user moves the position of the mobile phone terminal while viewing the display on the sub-display 50, so that the target mark 60 of the reader / writer and the center position 41 of the IC card antenna are obtained. Can be quickly and easily matched, and the mobile phone terminal can be placed in the “communicable area” of the reader / writer. In the case of the auto mode, in the mobile phone terminal of the present embodiment, the target mark 60 of the reader / writer and the center position 41 of the IC card antenna substantially coincide with each other and are within the “communicable area” of the reader / writer. When the mobile phone terminal is entered, non-contact communication with the reader / writer can be automatically executed.

  In addition, the design of the target mark is different for each electronic payment service system, a different contactless communication application is used for each electronic payment service system, and billing processing is also performed independently. . For this reason, the mobile phone terminal of the present embodiment determines which electronic payment service system the target mark corresponds to when the pattern of the target mark pattern 18 is recognized, and responds to the determination result. It is also possible to start a contactless communication application.

[Flow of the control unit when executing the communication area judgment program]

  Then, the control part 10 complete | finishes the said communicable area determination program as a process of step S18.

  Further, when it is determined in step S2 that the key is long-pressed and the automatic mode of the communicable area determination program is activated and the process proceeds to the process after step S20 in FIG. 9, the control unit 10 first performs the process in step S21. As a result, the coordinate data (x, y) of the target mark position correction offset (19) for correcting the distance D is acquired from the memory unit 16, and further, as a process of step S22, The position and data of the target mark pattern to be used for determining that the target mark pattern 19 exists substantially in the center are acquired from the memory unit 16.

  Next, the control unit 10 advances the processing to step S23, activates the function of the non-contact IC card unit 25, and sets the non-contact IC card unit 25 to a standby state for non-contact communication.

  Next, the control unit 10 advances the process to step S24, activates the camera unit 24, and starts capturing a real-time moving image.

  Next, in step S25, the control unit 10 determines the trimming position based on the offset 19 data, and further in step S26, subtracts the trimmed image cut out in accordance with the trimming position. It is displayed on the display 50.

  Thereafter, the control unit 10 confirms that the state of the non-contact IC card unit 25 is in the non-operating state, and then proceeds to a loop process from step S28 to step S31.

  When the process proceeds to the loop processing, the control unit 10 first, as the processing in step S29, as described above, the target mark pattern 18 and the target mark pattern 18 are approximately in the center of the moving image trimmed in consideration of the offset 19 minutes. Alignment for detecting whether or not there is a matching pattern, and when the pattern that substantially matches the target mark pattern 18 is present in the approximate center in the trimmed image, the size of the pattern is predetermined. It is determined whether the size is greater than or equal to the size.

  When there is a pattern that substantially matches the target mark pattern 18 and the size is equal to or larger than a predetermined size, the control unit 10 performs the process of step S30 in the non-contact IC card unit 25. Set the state to the operating state.
