Description

  The present invention relates to a portable terminal device including a finger detection sensor and a program.

Conventionally, as a mobile terminal device with a finger detection sensor, a mobile phone including a finger detection sensor that can also be used as a personal authentication function or an input device function (pointing device function) is known (see Patent Document 1). In this technology, whether the finger detection sensor is used as the identity authentication function or the pointing device function is automatically determined by determining the surface contact (area) where the finger touches the sensor surface. I try to switch. Similarly, conventionally, a portable terminal device is known in which fingerprint authentication is performed using a fingerprint sensor and movement of a finger is recognized as an operation input using the fingerprint sensor (see Patent Document 2).

The recording medium 3 is a detachable portable memory that supplies various data programs externally, and is configured by, for example, smart media, an IC card, or the like. The memory 4 is an internal memory having a work area, and is constituted by, for example, DRAM, SDRAM (Synchronous DRAM) or the like, and various data in the memory 4 is saved in the storage unit 2 as necessary.

  The telephone communication unit 5 takes in a signal from the reception side of a transmission / reception unit (baseband unit) connected to an antenna constituting the radio unit, demodulates it to a reception baseband signal, and then receives a reception speaker via the acoustic control unit 6. 7 to output sound. Further, the telephone communication unit 5 takes in the voice data input from the transmission microphone 8 from the acoustic control unit 6, encodes it into a transmission baseband signal, and then gives it to the transmission side of the transmission / reception unit to output from the antenna. . On the other hand, display data received and acquired via the telephone communication unit 5 by an e-mail function or the like is given to a main display unit 10 such as an LCD (Liquid Crystal Display) via a display control unit 9 and is displayed and output. The sub display unit 11 displays the current date and time, a simple message, an icon, and the like.

  The TV broadcast receiving unit 12 is connected to a TV antenna (not shown), selects a reception channel according to a user operation, extracts a broadcast signal of the station, and uses the OFDM (orthogonal frequency division multiplexing) The video signal, audio, and data (character data) are demodulated or separated from the multiplexed broadcast signal and decoded while analyzing the video signal, audio signal, and character signal. The data is displayed and output from the main display unit 10, and the television audio data is output from a sound speaker (not shown).

  The key operation unit 13 performs dial input, character input, command input, and the like. As shown in FIG. 2A, the key operation unit 13 includes the power key PK, the up / down / left / right direction instruction keys ( Cursor keys CK1 to CK4 and a determination key DK arranged at the center thereof, and the CPU 1 executes processing according to a key input signal from the key operation unit 13. The camera imaging unit 14 can shoot moving images in addition to still images. In addition to a photographing lens, a mirror / lens block such as a mirror, an imaging device, and a driving system thereof, a distance measuring sensor, a light amount sensor, an analog processing circuit A signal processing circuit, a compression / decompression circuit, and the like for adjusting and controlling the optical zoom and controlling drive control, shutter drive control, exposure, white balance, and the like during autofocus.

  The fingerprint sensor 15 is constituted by, for example, an image sensor ((area sensor)) and can be used for a plurality of purposes. The CPU 1 uses a sensor processing function (fingerprint authentication function, A predetermined sensor processing function is automatically selected from a pointing instruction function and a determination function. That is, the CPU 1 has a “fingerprint authentication mode” in which the fingerprint authentication function is operable according to the current style of the apparatus main body or the current application selected as a processing target, and a state in which the pointing instruction function is operable. In the “fingerprint authentication mode”, the sensor control unit 16 reads a digital image (fingerprint image data) corresponding to the unevenness of the fingerprint. The CPU 1 performs fingerprint authentication processing for collating fingerprint data (input data) read from the fingerprint sensor 15 via the sensor control unit 16 with finger-fingerprint data (registered data) registered in advance for each of a plurality of fingers. Execute.

  In the “pointing mode”, the sensor control unit 16 detects the movement direction and movement amount according to the movement of the finger, and the CPU 1 performs pointer movement processing and menu movement processing according to the detection result from the sensor control unit 16. Any one of the scroll processing is executed. In addition, the sensor control unit 16 detects whether or not the operation (sensor operation) on the fingerprint sensor 15 is accompanied by finger movement. In the case of a sensor operation (for example, double tap operation) that does not involve movement, the CPU 1 A determination process such as menu determination is executed using the determination function as an effective sensor processing function for each application. The sensor control unit 16 controls “ON / OFF” of the fingerprint sensor 15 in accordance with an instruction from the CPU 1.

  The style detection sensor 17 can detect each style that changes in accordance with the arrangement state of two housings (a display unit housing and an operation unit housing) that constitute a two-axis rotation type apparatus body. The CPU 1 is configured by a magnetic sensor or a microswitch, and the CPU 1 discriminates each style of the apparatus body based on each detection signal from the style detection sensor 17. In this case, the display unit casing is superimposed on the operation unit casing (closed style), the display unit casing is opened from this tile (forward open style or normal style), and the display unit casing is started from this style. Can be changed to a state in which the display unit housing is closed (view style).

  That is, FIG. 2A is a diagram showing a forward rotation open style (normal style). The key operation unit 13 is arranged in the operation unit casing 18A, and the main display unit is arranged in the display unit casing 18B. 10 is disposed, and a fingerprint sensor 15 is disposed below the main display unit 10. The main display unit 10 and the fingerprint sensor 15 are exposed to the outside. FIG. 2B shows a view style. In this view style, the key operation unit 13 of the operation unit casing 18A is covered with the display unit casing 18B. The main display unit 10 and the fingerprint sensor 15 are exposed to the outside. In this view style, since the key operation unit 13 of the operation unit casing 18A is covered with the display unit casing 18B, the side keys SK1 and SK2 arranged on one side of the operation unit casing 18A. , SK3 is used.

FIG. 3 is a diagram for explaining the style-specific sensor processing function table 21.
The style-specific sensor processing function table 21 is used to select any one of application-specific sensor processing functions (fingerprint authentication function, pointing instruction function, determination function) according to the current style of the apparatus body as the current effective function. It is a table. In this case, “fingerprint authentication mode” is set as a sensor processing function (sensor mode) corresponding to “open style”, and the fingerprint authentication function is selected as an effective function in “open style”. Further, “pointing mode” is set as a sensor processing function (sensor mode) corresponding to “view style”, and the pointing instruction function is selected as an effective function in “view style”.

FIG. 4 is a diagram for explaining the application-specific sensor processing function table 22.
The application-specific sensor processing function table 22 is a currently effective function of any of the application-specific sensor processing functions (fingerprint authentication function, pointing instruction function, determination function) corresponding to the application currently selected as the processing target. It is a table for selecting as. That is, “fingerprint authentication mode” is set as a sensor processing function (sensor mode) corresponding to the applications “phone” and “mail” of the voice call function and the electronic mail function. In the figure, “fee-specific destination” written in the “telephone” and “mail” function description columns indicates the processing contents executed together with the fingerprint authentication processing. For example, a private-related destination is read at the time of fingerprint authentication. Sometimes the index finger is used, and the middle finger is used to read business-related destinations. This indicates that the type of can be specified.

  Further, “pointing mode” is set as a sensor processing function (sensor mode) corresponding to the application “address book” and “Web” of the address book function and the Internet connection function (Web access function). “Cursor movement” and “Pointer movement” described in the function description column of “Address book” and “Web” indicate processing contents executed as a pointing instruction function, and when reading arbitrary personal data from the address book Indicates that the cursor movement process is executed, and when an arbitrary URL is selected from the URL list for accessing the desired Web page, the pointer movement process is executed.

  In addition, “determination (touch) mode” is set as a sensor processing function (sensor mode) corresponding to the application “camera” of the camera function, and “shutter” described in the function description column is a pointing instruction function. In the case of camera shooting, a shutter-on process (shooting process) is executed by a touch operation on the fingerprint sensor 15. In addition, “fingerprint authentication mode” is set as a sensor processing function (sensor mode) corresponding to the TV function application “TV”, and “channel selection” described in the function description column is displayed together with the fingerprint authentication processing. Indicates the processing contents to be executed. For example, by setting the correspondence between each finger and the channel arbitrarily, it is possible to switch to the channel corresponding to the finger by changing the finger type when selecting the channel. Is shown.

  Next, the operation concept of the cellular phone device in this embodiment will be described with reference to the flowcharts shown in FIGS. Here, each function described in these flowcharts is stored in the form of a readable program code, and operations according to the program code are sequentially executed. In addition, the operation according to the above-described program code transmitted via the transmission medium can be sequentially executed. In other words, in addition to the recording medium, an operation peculiar to this embodiment can be executed by using a program / data supplied externally via a transmission medium.

FIG. 5 and FIG. 6 are flowcharts showing the overall operation of the mobile phone device that starts to be executed in response to the operation of the power key PK.
First, at the time of open start when the power key PK is operated in the open style, the CPU 1 turns on the fingerprint sensor 15 to set it in an operable state (step S1), and as an initial mode of the fingerprint sensor 15 After selecting the “fingerprint authentication mode” (step S2), a guidance display for prompting a fingerprint input operation is performed (step S3). Then, the presence or absence of a touch operation (sensor operation) on the fingerprint sensor 15 is checked (step S4). When the sensor operation is performed, that is, when fingerprint image data is read from the fingerprint sensor 15 via the sensor control unit 16. In step S4 (YES in step S4), a fingerprint authentication process for collating this fingerprint data (input data) with previously registered fingerprint data (registered data) is executed (step S5), and both are characteristically matched. Whether or not (step S6).

  As a result, if both are characteristically inconsistent (verification NG) (NO in step S6), it is recognized as an operation by a third party, and the process returns to step S3. However, in the case of collation OK (YES in step S6), it is recognized as an operation by a regular user, and the process proceeds to the next step S7, where the style-specific sensor processing function table 21 is stored. By referencing, the “sensor mode” corresponding to “open style” is selected. In this case, “fingerprint authentication mode” is selected as the sensor mode. In this state, the telephone communication unit 5 is activated to perform standby processing for registering the current position, and a standby state for telephone / mail is entered while a predetermined standby image is read out and displayed (step S8). If it is detected that there is an incoming call / mail (YES in step S9), an incoming call notification for generating and outputting an incoming melody is performed and a call or mail incoming process is executed (step S10).

  If no call / mail is received in the standby state (NO in step S9), the fingerprint sensor 15 is checked for "ON / OFF" (step S11). Next, the presence or absence of a touch operation (sensor operation) on the fingerprint sensor 15 is checked. Here, if no sensor operation is performed (NO in step S12), the flow proceeds to the flow of FIG. 6, and the presence / absence of a style change is checked based on the detection signal from the style detection sensor 17 (step S24). It is checked whether or not the keys on the unit 13 or the side keys SK1 to SK3 are operated (step S32). Here, if neither the style change nor the key operation is performed (NO in step S32), the standby state is returned (step S8 in FIG. 5), but if the style is changed (YES in step S24), Whether it is a change to "open style" (step S25) or a change to "view style" is checked (step S28).

  Here, when “open style” is changed to “closed style” (NO in step S28), the fingerprint sensor 15 is turned “OFF” (step S31), but if it is changed to “open style”. 3 (YES in step S25), after the fingerprint sensor 15 is turned “ON” (step S26), the style-specific sensor processing function table 21 is referred to, and the “sensor mode” corresponding to “open style” is shown in the example of FIG. Then, the “fingerprint authentication mode” is selected (step S27). If it is a change to “view style” (YES in step S28), after the fingerprint sensor 15 is turned “ON” (step S29), the style-specific sensor processing function table 21 is referred to and “view style” is set. As the corresponding “sensor mode”, the “pointing mode” is selected in the example of FIG. 3 (step S30). Thus, for example, when the “open style” is changed to the “view style”, the “sensor mode” is switched from the “fingerprint authentication mode” to the “pointing mode” with the change. After execution of such processing, the process returns to the standby state described above (step S8 in FIG. 5).

  On the other hand, when any key is operated (YES in step S32), it is determined whether the operation is an activation operation instructing activation of the application (step S33). If it is not the activation operation, the process proceeds to step S43, and the operation key is set. As a corresponding process, for example, after executing a menu display process or the like, the process returns to the standby state described above (step S8 in FIG. 5). On the other hand, when an activation operation for activating one of the applications is performed, for example, in a state where the application menu is displayed, the direction instruction keys (cursor keys) CK1 to CK4 are operated, and an arbitrary one is selected from the menu screen. When a menu item is selected as a processing target and the enter key DK is operated to instruct activation of the selection menu (YES in step S33), access restriction (security function restriction) is applied to the application. It is checked whether it is set (step S34).

  Now, when activation is instructed for a private function such as an address book function or an e-mail function, that is, when an application for which a restriction setting (security setting) is set is selected as a processing target (in step S34). YES), a user authentication process (fingerprint authentication process) is performed to confirm whether or not the user is a legitimate user prior to the execution of the process corresponding to the application (steps S35 to S39). When an application without setting is selected as a processing target (NO in step S34), the application processing is performed without performing the above-described fingerprint authentication processing (step S40). As in the case described above, the fingerprint authentication process in this case also selects the “fingerprint authentication mode” as the sensor mode (step S35), and then displays a guidance display for prompting a fingerprint input operation (step S36). When a sensor operation is performed and fingerprint image data is read from the detected fingerprint sensor 15 via the sensor control unit 16 (YES in step S37), fingerprint authentication processing is executed (step S38).

  As a result, it is checked whether or not the collation is OK (step S39). If the collation is NG (NO in step S39), the process returns to the above-described step S36. Recognizing that there is one, the process proceeds to step S40, referring to the application-specific sensor processing function table 22, and selecting the “sensor mode” corresponding to the application (step S41). Then, the process corresponding to the application is started (step S41), and when the process ends (YES in step S42), the process returns to the standby state described above (step S8 in FIG. 5).

  In this case, for example, if the selected application is “telephone”, “mail”, “TV”, “fingerprint authentication mode” is selected as the sensor mode, and if “address book”, “Web” is selected. If “pointing mode” is selected and “camera” is selected, “decision mode” is selected and execution thereof is started. Here, when the application is “phone” or “mail”, by changing the finger used at the time of fingerprint authentication according to whether the call destination or the mail destination is a private relationship or a business relationship at the time of touch operation on the fingerprint sensor 15, A finger destination display process for reading out finger destinations corresponding to the type and displaying a list is executed.

  If the application is “address book” or “Web”, a cursor movement process or a pointer movement process is executed by a touch operation on the fingerprint sensor 15 (an operation to move a finger). The shutter-on process (photographing process) is executed by a touch operation on the fingerprint sensor 15. In the case of “TV”, the channel switching process is executed by a touch operation on the fingerprint sensor 15. At this time, the process of switching to the channel corresponding to the finger is performed by changing the type of the finger when selecting the channel. Done.

  On the other hand, when the fingerprint sensor 15 is “ON” in the standby state (YES in step S11 in FIG. 5), when a touch operation (sensor operation) is performed on the fingerprint sensor 15 (YES in step S12), The current sensor mode is determined (step S13). If the sensor mode is “fingerprint authentication mode” (YES in step S13), fingerprint authentication processing is executed (step S14). As a result, in the case of collation OK (YES in step S15), the user beforehand A set application (for example, mail processing) is started (step S16), and the processing is executed (step S17). Thus, the setting application can be activated not only by the activation operation instructing activation of the application but also by a sensor operation in the “fingerprint authentication mode”. After executing the setting application process (step S17), the process returns to the standby state described above (step S8).

  Further, if the sensor mode is “pointing mode” at the time of sensor operation (NO in step S13), it is determined whether the operation is a finger movement based on the detection signal from the sensor control unit 16 (step S18). For example, the cursor movement process is executed accordingly (step S23). If it is a touch operation (NO in step S18), it is checked whether it is a double tap operation instructing selection (YES in step S19). . If it is a double tap operation (decision operation), there is a selection target (for example, a menu item, a data item, etc.) at the current cursor position, that is, a double tap operation (determination is performed with the cursor set to the selection target). It is checked whether or not (operation) has been performed (YES in step S20), and if there is a selection target at the cursor position, processing corresponding to the selection target is executed (step S21). If the selection target is an application, it is possible to execute finger-specific destination display processing, cursor movement processing, pointer movement processing, and channel selection processing by switching to the corresponding sensor mode as described above. Then, after the process is completed (YES in step S22), the process returns to the standby state described above (step S8).

  As described above, in this embodiment, the sensor processing function (sensor mode) for each application of the fingerprint sensor 15 that can be used for a plurality of applications is stored and managed in the sensor processing function table 21 for each style corresponding to the style of the apparatus body. In this state, the CPU 1 determines the current style based on the detection signal from the style detection sensor 17, and selects a sensor processing function (sensor mode) corresponding to this style as the current effective function. A sensor processing function that matches the current style can be selected and the selection is ensured.

  In this case, it is determined whether or not the current style is a style (open style) in which the direction instruction keys CK1 to CK4 arranged on the operation unit casing 18A side are exposed. If a mode (view style) is selected so that the direction instruction keys CK1 to CK4 on the operation unit casing 18A side are covered with the display unit casing 18B, the “viewing mode” is selected. In this case, the fingerprint sensor 15 can be substituted for the direction instruction keys CK1 to CK4.

  The same applies to the determination key DK arranged on the operation unit casing 18A side, and the fingerprint sensor 15 can be used as a substitute for the determination key DK. In addition, when a restricted application among multiple applications is selected for processing, selecting “Fingerprint authentication mode” as the sensor mode, regardless of the current style, is effective for security measures. It will be a thing.

  In a state where the sensor processing function (sensor mode) for each application of the fingerprint sensor 15 that can be used for a plurality of applications is stored and managed in the application-specific sensor processing function table 22 corresponding to the application, the CPU 1 The sensor processing function that matches the current processing target application can be selected by specifying the application selected as the processing target from and selecting the sensor processing function (sensor mode) corresponding to this application as the current effective function. Together, the choice is assured. In this case, when a restricted application among a plurality of applications is selected as a processing target, the CPU 1 selects “fingerprint authentication mode” as the sensor mode regardless of the current processing target application. This is effective for security measures.

In the above-described embodiments, the case where the fingerprint sensor 15 is an image sensor is illustrated, but the present invention is not limited to this, and a pressure detection type or electrostatic capacitance type fingerprint sensor (area sensor) may be used.
In addition, the fingerprint sensor 15 may be configured by a transparent touch sensor and an image sensor that is stacked below the transparent touch sensor. In this case, corresponding to the transparent touch sensor, a finger touch position is detected according to the touch state, a pointing instruction unit for detecting the finger moving direction and the moving amount is provided, and the image sensor is also supported. Thus, a fingerprint reading unit that reads fingerprint image data may be provided.

Further, at the time of fingerprint authentication, not only the case where the digital fingerprint image is collated by the pattern matching method, but the feature point may be extracted from the fingerprint data and collated.
In addition, the present invention is not limited to a mobile phone device with a finger detection sensor, and can be similarly applied to a mobile terminal device such as a PDA, an electronic camera, an electronic watch, and a music player with a finger detection sensor.
