As an input means when there is no physical space to be used, it is widely used for personal computers, PDAs, ATMs, car navigation systems, and the like.

  For such a touch panel, various methods for facilitating input have been proposed. For example, a technique has been proposed in which an enlarged area is designated on a touch panel and an object in the designated enlarged area is enlarged and displayed (for example, see Patent Documents 1 to 3).

  However, although the size of the finger differs depending on the user, in Patent Documents 1 to 3, since the enlargement ratio is constant when the object is enlarged, enlargement is sufficient when operating the object for a person with a large finger. In some cases, it is difficult to operate, and for a person with a small finger, there is a problem that the enlargement is excessive, and conversely, a portion hidden on the screen appears due to the enlargement of the object.

  On the other hand, the indicator on the touch panel is not limited to the finger, and a pen or stylus may be used. However, when the pen or stylus is used on the touch panel, the pen or stylus nib is used regardless of the size of the finger. The size is related to operability.

  The HDD (hard disk) 14 includes, for example, an OS 31 for controlling the entire notebook PC 1 such as Windows (registered trademark), various drivers for operating the peripheral devices (display driver 32a, touch panel driver 32b, mouse) 32) and a function for storing an object enlargement application 33 for enlarging and displaying an object on the screen of the display device 15, and another application 34 for a specific task.

  The display device 15 is, for example, a liquid crystal display device, and has a function of displaying various information according to the control of the CPU 11. The display device 15 converts display information into a video signal according to the control of the CPU 11, and responds to the converted video signal. Various information is displayed on the display screen (LCD panel).

  The touch panel 16 is provided on the display screen of the display device 15, and is used for an operator to input information by touching an indicator. An infrared shading type, a capacitance type, an electromagnetic induction type, Various systems such as an image recognition system, a resistive film system, an acoustic pulse system, and a surface acoustic wave system can be used.

  The input unit 17 is a user interface for a user to perform an input operation. The input unit 17 is a keyboard composed of various keys for inputting characters, commands, and the like, a tracks pointer for moving a cursor on the screen, and selecting various menus. Etc.

  A fingerprint reader 18 (FPR: Finger Print Reader) optically reads a fingerprint of an operator's finger (for example, thumb), converts the read information into an electrical signal, and outputs it as a fingerprint image.

  The power supply circuit 19 includes an AC adapter, an intelligent battery, a charger for charging the intelligent battery, a DC / DC converter, and the like, and supplies power to each device under the control of the CPU 11.

Improve the operability when doing. Hereinafter, functions realized by the CPU 11 executing the program will be described with the program as an operation subject.

  The configuration and operation of the object enlargement application 33 will be described in detail with reference to FIGS. FIG. 2 shows a functional configuration diagram of the object enlargement application 33. FIG. 3 is a diagram for explaining a method for calculating a finger size based on a fingerprint image. As shown in FIG. 2, the object enlargement application 33 calculates the finger size (Wf / Ws) based on the fingerprint image storage unit 41 that stores the fingerprint image read by the fingerprint reading device 18 and the fingerprint image. Based on the finger size (Wf / Ws) calculated by the finger size determination unit 42 (functioning as a pointer size detection unit) and the finger size determination unit 42, the enlargement ratio of the object on the display screen of the display device 15 is determined. An enlargement target determining unit 43 (functioning as an enlargement rate determining unit) and an enlargement target object determining unit 44 (functioning as an enlargement target object determining unit) that determines an enlargement target object based on coordinate information input from the touch panel driver 32b. ) And the enlargement target object determined by the enlargement object determination unit 44 are determined by the enlargement rate determination unit 43 Was to generate an enlarged object expanding at magnification includes via the display driver 32a, the enlarged object generation unit 45 to be displayed on the display device 15 (which functions as an extension object generating means), a.

  In the notebook PC 1 configured as described above, when the operator touches the sensor surface of the fingerprint reader 18 with a finger (here, the thumb is used), the fingerprint reader 18 reads the fingerprint of the finger, The fingerprint image is output to the object enlargement application 33.

  In the object enlargement application 3, a fingerprint image is stored in the fingerprint image storage unit 41. The finger size determination unit 42 calculates the finger size (Wf / Ws) based on the fingerprint image stored in the fingerprint image storage unit 51. Here, in the fingerprint reader 18 shown in FIG. 3, Ws indicates the full width of the sensor, Wf indicates the finger width, and the finger size (finger width) is defined by the finger width Wf / the total width Ws of the sensor. Here, the finger size is defined by finger width Wf / sensor full width Ws, but the finger size defining method is not limited to this, and for example, the area of the fingerprint image or the like may be used. Further, when the fingerprint reader 18 outputs bitmap data, the number of horizontal dots in FIG. 3 may be set as the finger size. In addition, when the finger part is black or dark and the other part is white or bright, the finger size is determined relatively by measuring the black part ratio of the fingerprint image and the average brightness of the fingerprint image. Good. This is because if the finger is large, the black portion ratio is high and the average brightness is low, and if the finger is small, the reverse is true.

  The enlargement rate determination unit 43 determines the enlargement rate of the object based on the finger size (Wf / Ws) calculated by the finger size determination unit 42. For example, when Wf / Ws> 0.8, the enlargement ratio is “large (eg, doubled)”, and when 0.6 ≦ Wf / Ws ≦ 0.8, the enlargement ratio is “medium (eg, 1. 5 times) ”and Wf / Ws <0.6, the enlargement ratio is determined to be“ small (for example, 1.2 times) ”.

  Coordinate information corresponding to the touch operation of the operator's touch panel 16 is input from the touch panel driver 32b to the enlargement target object determination unit 44, and an enlargement target object is determined based on the coordinate information. For example, if there is an object within a predetermined range (periphery) centered on the touch position, the object is determined as an object to be enlarged, and if there is no object within the predetermined range (periphery) from the touch position, An object can be determined as an object to be enlarged. Here, the predetermined range can be, for example, an L × L square range with the touch position as the center, or a circle range with a radius L with the touch position as the center.

  The enlargement object generation unit 45 enlarges the enlargement target object determined by the enlargement target object determination unit 44 at the enlargement rate determined by the enlargement rate determination unit 43, generates an enlargement object, and via the display driver 32a, It is displayed on the display device 15.

  FIG. 4 is a diagram for explaining an enlarged display by the object enlargement application 33. Assume that the display device 15 displays objects such as a button 50 (a minimize button, an undo button, and a close button), a scroll bar 51, and a folder 52 as shown in FIG. Here, when the operator operates the object, it is assumed that the display of the object is too small to perform the operation with a finger. In this case, the object to be operated can be enlarged and displayed.

  As shown in FIG. 5B, when the operator wants to enlarge and display the button 50 and touches the periphery of the button 50 with a finger, the object enlargement application 33 determines the button 50 as the enlargement target object. Then, the button 50 is enlarged and displayed as shown in FIG. On the other hand, when the operator wants to enlarge and display all the objects on the screen, as shown in FIG. 5C, when the operator touches a position where there is no object around, the object enlargement application 33 All objects (button 50, scroll bar 51, folder 52, etc.) are determined as objects to be enlarged, and all the objects are enlarged and displayed as shown in FIG. Here, the display state of the enlarged object is maintained, but after displaying the enlarged object, for example, the timer is used to count the time and return to the original size display after a predetermined time has elapsed, or the enlargement cancel button is displayed. When the enlargement cancel button is pressed, the original display may be restored. Thus, the operator can improve the operability of finger input on the touch panel by displaying the object in an enlarged manner.

  FIG. 5 is a flowchart for explaining the flow of object enlargement processing by the object enlargement application 33. In this figure, when the object enlargement application 33 is activated, the object enlargement application 33 displays guidance on the screen of the display device 15 instructing to place the thumb on the sensor surface of the fingerprint reader 18. In response to this, when the operator contacts the thumb with the sensor surface of the fingerprint reading device 18, the fingerprint reading device 18 reads the fingerprint of the thumb (step S1) and outputs the read fingerprint image to the object enlargement application 33. .

  In the object enlargement application 33, the finger size determination unit 42 calculates the finger size (Wf / Ws) based on the fingerprint image (step S2). The enlargement ratio determining unit 43 determines the enlargement ratio based on the finger size (Wf / Ws) (step S3).

  When a touch operation is performed on the touch panel 16 (step S4), the touch panel driver 32b outputs the coordinate position to the enlargement target object determination unit 44. The enlargement target object determination unit 44 determines whether or not the periphery of the object has been touched (step S5). When the periphery of the object has been touched (“Yes” in step S5), the enlargement target object determination unit 44 Determines that the object is an enlargement target object, and the enlargement object generation unit 45 enlarges the determined enlargement target object at the enlargement rate determined by the enlargement rate determination unit 53 to generate an enlargement object, and displays the display driver 32a. Then, the image is displayed on the display device 15 (see FIGS. 4B and 4D) (step S6).

  On the other hand, when the periphery of the object is not touched (“No” in step S5), the enlargement target object determination unit 44 determines all the objects on the screen as enlargement target objects, and the enlargement object generation unit 45 The determined enlargement target object is enlarged at the enlargement rate determined by the enlargement rate determining unit 53 to generate an enlarged object, and is displayed on the display device 15 via the display driver 32a (see FIGS. 4C and 4E). (Step S7). Here, the display of the enlarged object is held for a predetermined period, and after the predetermined period, the display returns to the display of the object of the original size. In addition, as described above, instead of a configuration in which the original size is restored after a predetermined period of time, an enlargement cancel button is provided on the screen, and when the user presses the enlargement cancel button, the original size is displayed. You may decide to return it.

  Subsequently, when a normal touch operation on the enlarged object is detected on the touch panel 16 after the object is enlarged and displayed ("Yes" in step S8), the flow is finished. In the OS 31 or the like, processing according to the touch operation is performed.

  On the other hand, when an abnormal touch operation on the enlarged object is detected on the touch panel 16 (for example, touching other than the enlarged object or touch error when two buttons are operated at the same time) (“No” in step S8), the fingerprint image is displayed. Since there is a possibility of calculation error of the enlargement ratio of the object due to the failure to read correctly, a display for instructing to place the thumb on the fingerprint reader is performed again (step S9). In response to this, when the operator places the thumb on the fingerprint reading device 18, the fingerprint reading device 18 reads the thumb fingerprint (step S10), and the finger size determination unit 42 determines the finger size (Wf) based on the fingerprint image. / Ws) is calculated (step S11). The enlargement rate determination unit 43 determines the enlargement rate based on the finger size (Wf / Ws) (step S12), determines whether the previous touch operation was around the object (step S5), and recalculates. The enlargement target object is enlarged and displayed again at the enlargement ratio (steps S6 and S7). In this way, touch mistakes can be recovered.

  As described above, according to the first embodiment, the finger size determination unit 42 detects the finger size based on the fingerprint image of the finger read by the fingerprint reading device 18, and the enlargement ratio determination unit 43 Since the enlargement ratio of the enlargement target object on the display screen is determined based on the detected finger size, and the enlargement object generation unit 45 enlarges and displays the enlargement target object with the decided enlargement ratio. The object can be enlarged and displayed at an enlargement rate according to the size of the operator's finger, and the operability of the touch panel can be improved according to the size of the operator's finger.

  Further, when there is an object within a predetermined range with the finger touch point as the center, the enlargement target object determination unit 44 determines the existing object as the enlargement target object, while at the same time with the touch point as the center within the predetermined range. If no object exists, all the objects displayed on the display screen are determined as the enlargement target objects, so that the operator can easily select the desired enlargement target object.

  Note that the object to be enlarged is not limited to the buttons, bars, and folders described above, but may be other objects (for example, icons (registered trademark), switches, software keyboards, etc.). Further, the curvature of the software Carved Keyboard may be changed based on the size of the finger.

  In the case of a system for performing fingerprint authentication, a fingerprint image, a finger size (Wf / Ws) calculated based on the fingerprint image, and an enlargement ratio thereof are stored in advance, and the fingerprint image authenticated in the case of object enlargement processing is stored. It is also possible to read out and use the enlargement ratio corresponding to.
