Abstract

<P>PROBLEM TO BE SOLVED: To provide a data processor having structure for preventing the generation of an error in authentication processing in which a user makes the finger slide to a line sensor. <P>SOLUTION: When one-dimensional images are read from the finger F, an index to guide the sliding of the finger F is moved. Thus, it is necessary for the user only to make the finger F slide to a line sensor 110 corresponding to the moving index. Therefore, it is possible even for an unfamiliar user to make the finger F easily slide at a proper speed. Also, it is possible for the user to read the proper number of one-dimensional images from the proper position of the finger F by the line sensor 110. Thus, it is possible to prevent the error of the authentication processing for turning the plurality of one-dimensional images to two-dimensional images. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to a data processing apparatus that reads a two-dimensional image from a finger and performs authentication processing, and more particularly to a data processing apparatus having a structure in which a user slides a finger on a fixed line sensor.

  Conventionally, there is a biometric matching device as a security system using biometric information. The biometric matching device is used, for example, in a security system for limiting who can enter a specific area.

  The biometric information is provided on the body of the person and will not be lost. Moreover, it is not known to others like a personal identification number and is not stolen like a key. Therefore, the biometric matching device is good in both convenience and security.

  A fingerprint collation device, which is one of such biometric collation devices, includes, for example, an information storage medium such as a RAM (Random Access Memory), an information input device such as a CCD (Charge Coupled Device) camera, and a computer unit. Have.

  In the fingerprint collation apparatus as described above, a fingerprint pattern is registered in advance as biometric information of one person in the information storage medium. At the time of collation, the fingerprint pattern of the person to be inspected is input with the information input device.

  The input fingerprint pattern and the registered fingerprint pattern are verified by data processing such as pattern matching in the computer unit. If the fingerprint patterns to be collated in this way match, it is recognized that the inspected person is a registered person.

  There are various types of biometric matching devices, but in the case of using image data such as a fingerprint image or a palm print image as biometric information, these image data are acquired by an imaging device.

  There are various types of imaging devices, one of which is a line sensor. The line sensor reads a one-dimensional image from a finger or the like, but a two-dimensional image is necessary for the authentication process. For this reason, it is necessary to relatively move the line sensor and the finger in order to generate a two-dimensional image.

  Therefore, there are those that move the line sensor with respect to the fingers, those that move the optical system interposed between the fingers and the line sensor, and those that allow the user to slide the fingers with respect to the fixed line sensor.

  At present, the biometric verification device as described above may be incorporated in a data processing device such as a facsimile device. Furthermore, some of such data processing devices perform authentication processing by the biometric matching device in real time with a computer unit.

Currently, there are various proposals for the biometric matching device as described above (see, for example, Patent Documents 1 and 2).

  However, in a data processing apparatus in which a user slides a finger with respect to a fixed line sensor as described above, for example, if the user is unfamiliar with the finger, the finger is moved at an inappropriate speed and an error occurs in the authentication process. May occur.

  Further, in a data processing apparatus such as the facsimile apparatus described above, an error may occur in the authentication process even if the user moves his / her finger at an appropriate speed. That is, in a data processing apparatus such as a facsimile machine, predetermined processing such as expansion of received data is also executed in real time by the computer unit.

  For this reason, for example, if authentication processing and data reception occur simultaneously, the processing capacity of the computer unit may be insufficient. In this case, the operation in which the computer unit causes the line sensor to read the one-dimensional image and executes the authentication process is delayed.

  Then, the interval at which the one-dimensional image is read from the finger becomes excessive, and the number of one-dimensional images to be read is insufficient. For this reason, an error occurs in the authentication process in which a plurality of one-dimensional images are converted into two-dimensional images.

  The present invention has been made in view of the above-described problems, and provides a data processing apparatus having a structure capable of preventing an error from occurring in an authentication process in which a user slides a finger on a line sensor.

  A data processing apparatus according to the present invention includes a line sensor that reads a one-dimensional image from a finger, a data processing unit that repeatedly causes the line sensor to read the one-dimensional image and executes authentication processing as a two-dimensional image, and a slide of the finger to be read. A movement guiding unit that moves the index to be guided.

  Therefore, in the data processing apparatus of the present invention, the data processing unit causes the line sensor to repeatedly read the one-dimensional image, and executes the authentication process using the plurality of one-dimensional images as two-dimensional images. As described above, when the line sensor reads a one-dimensional image from the fingers, the movement guide unit moves an index for guiding the slide of the fingers to be read. For this reason, the user should just slide a finger | toe to a line sensor corresponding to the parameter | index to move. In addition, an appropriate number of one-dimensional images can be read from an appropriate position of the fingers by the line sensor.

  Furthermore, a data processing apparatus according to another aspect of the present invention includes a load detection unit that detects a load state of the data processing unit, a movement speed of an index by a movement guide unit corresponding to the detected load state, and a primary by a line sensor. A speed adjusting unit for adjusting the reading timing of the original image;

  Therefore, in the data processing apparatus of the present invention, the load detection unit detects the load state of the data processing unit that executes the authentication process. Corresponding to the detected load state, the speed adjusting unit adjusts the moving speed of the index by the movement guiding unit and the reading timing of the one-dimensional image by the line sensor. For this reason, even if the authentication processing of the data processing unit is delayed due to the occurrence of parallel processing or the like, the position where the one-dimensional image is read from the finger and the number of the one-dimensional images to be read can be made constant.

  The computer program of the present invention is a computer program for the data processing apparatus of the present invention, in which a process for moving an index for guiding a finger slide to be read is moved to a movement guiding unit, and a one-dimensional image is repeatedly read by a line sensor. Processing, authenticating a plurality of read one-dimensional images as two-dimensional images, processing for detecting a load state of the data processing unit, and a moving speed of the index by the movement guide unit corresponding to the detected load state And a process for adjusting the reading timing of the one-dimensional image by the line sensor.

  It should be noted that the various components referred to in the present invention need only be formed so as to realize their functions. For example, dedicated hardware that exhibits a predetermined function, data provided with a predetermined function by a computer program It can be realized as a processing device, a predetermined function realized in the data processing device by a computer program, an arbitrary combination thereof, or the like.

  The various components of the present invention do not necessarily have to be independent of each other. A plurality of components are formed as a single member, and a single component is formed of a plurality of members. It may be that a certain component is a part of another component, a part of a certain component overlaps with a part of another component, or the like.

  In the data processing apparatus of the present invention, when a one-dimensional image is read from a finger, an index for guiding the finger slide is moved. For this reason, the user should just slide a finger | toe to a line sensor corresponding to the parameter | index to move. Therefore, even an unfamiliar user can easily slide his / her finger at an appropriate speed. In addition, an appropriate number of one-dimensional images can be read from an appropriate position of the fingers by the line sensor. For this reason, it is possible to prevent an error in authentication processing in which a plurality of one-dimensional images are converted into two-dimensional images.

  Furthermore, in the data processing apparatus according to another aspect of the present invention, the moving speed of the index and the reading timing of the one-dimensional image are adjusted in accordance with the load state of the data processing unit that executes the authentication process. For this reason, even if the authentication processing of the data processing unit is delayed due to the occurrence of parallel processing or the like, the position where the one-dimensional image is read from the finger and the number of the one-dimensional images to be read can be made constant. For this reason, it is possible to prevent an error in authentication processing in which a plurality of one-dimensional images are converted into two-dimensional images.

  An embodiment of the present invention will be described below with reference to the drawings. The data processing apparatus according to the present embodiment is, for example, an MFP (Multi Function Peripherals) 100. As shown in FIG. 1, the MFP 100 includes a line sensor 110 that reads a one-dimensional image from a fingertip F that is a finger, a movement guide unit 120 that moves an index that guides the slide of the fingertip F to be read, and a line sensor 110. A data processing unit 130 that repeatedly reads a one-dimensional image and executes authentication processing as a two-dimensional image, a load detection unit 140 that detects a load state of the data processing unit 130, and a movement guide corresponding to the detected load state A speed adjusting unit 150 that adjusts the moving speed of the index by the unit 120 and the reading timing of the one-dimensional image by the line sensor 110, a data receiving unit 160 that executes data reception from the outside, and data printing that prints out the received data. Unit 170, document reading unit 180 that reads a document image from a scanned document, and transmits the document image to the outside With a chromatography data transmission unit 190, a.

  In MFP 100 according to the present embodiment, for example, as shown in FIG. 2, line sensor 110 is fixed to the upper surface of main body housing 101 or the like. The movement guide unit 120 includes a display device 121 such as an LCD (Liquid Crystal Display) that displays an image.

  The display device 121 is disposed at a position adjacent to the line sensor 110. The movement guiding unit 120 also includes a moving image output unit 122 that displays a moving image of the index moving on the display device 121.

  The data processing unit 130 includes a computer unit including a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and the like as hardware.

  The data processing unit 130 is implemented with a predetermined computer program. Corresponding to the computer program, various data processing such as integrated control of the line sensor 110 and the movement guide unit 120 is executed.

  More specifically, the data processing unit 130 executes a plurality of data processes in parallel corresponding to the priority levels defined for each as a data process separate from the authentication process. Then, the reception process is executed in real time as one of the data processes as described above.

  This reception processing is data processing that occurs at an arbitrary timing due to the data reception of the data reception unit 160. For example, the reception data of the data reception unit 160 is expanded into a print image, and the print image is data-printed. And the like.

  Further, the data processing unit 130 executes an integration process for integrating numerical values as one of a plurality of data processes executed in parallel. However, this integration process is executed, for example, with the lowest priority that has a lower priority than the authentication process and the reception process.

  The load detection unit 140 detects the above-described numerical value at a constant period when the movement guiding unit 120 moves the index, and detects the load state based on the detected numerical value increment. Note that the data processing unit 130 resets the above numerical value at least when the movement guiding unit 120 starts moving the index and when it ends.

  In the present embodiment, in order to simplify the description, the data processing unit 130 is composed of one computer unit as described above, and the load detection unit 140 and the speed adjustment unit 150, which are separate from this, have dedicated hardware. A structure consisting of wear is assumed.

  However, the data processing unit 130, the load detection unit 140, and the speed adjustment unit 150 may each be realized as a function of one computer unit by a computer program.

  In such a case, for example, the computer program of the MFP 100 is read as a process of moving an index for guiding the slide of the fingertip F to be read to the movement guiding unit 120 and a process of causing the line sensor 110 to read a one-dimensional image repeatedly. A process of authenticating a plurality of one-dimensional images as a two-dimensional image, a process of detecting a load state of the data processing unit 130, a moving speed of an index by the movement guiding unit 120 corresponding to the detected load state, and the line sensor 110 Is a software for causing the MFP 100 to execute the process of adjusting the reading timing of the one-dimensional image by.

  In the configuration as described above, MFP 100 according to the present embodiment specifies a user by fingerprint authentication, and executes user recording, function restriction, and the like. Therefore, when the user inputs the start of use to the MFP 100, as shown in FIG. 2, first, the user presses the display device 121 such as "Press the fingertip against the right line sensor and move it forward along the arrow." Is displayed.

  At this time, an arrow is also displayed on the display device 121 as an index for guiding the movement of the fingertip F. When the user presses the fingertip F against the line sensor 110 in such a state, as shown in FIG. 3, in the MFP 100 that detects this (step S1), a moving image for moving the index is displayed on the display device 121. (Step S2).

  Therefore, the user slides the fingertip F in accordance with the movement of the index displayed on the display device 121. Then, a one-dimensional image is read from the sliding fingertip F by the line sensor 110 (step S3).

  At this time, the data processing unit 130 causes the line sensor 110 to repeatedly read the one-dimensional image, and executes the authentication process using the plurality of one-dimensional images as two-dimensional images (step S4). However, in MFP 100 according to the present embodiment, data reception unit 160 receives data during the authentication process as described above, and data processing unit 130 executes the authentication process and the reception process in parallel. There is also.

  When parallel processing occurs in this way, the speed of authentication processing changes. Therefore, in MFP 100 of the present embodiment, when the authentication process is being executed, the load state of data processing unit 130 is always detected (step S5).

  More specifically, the data processing unit 130 accumulates numerical values as parallel processing with the lowest priority when executing the authentication processing. This numerical value is detected at a constant cycle, and the load state is detected by the increment.

  Corresponding to the load state of the data processing unit 130 detected in this way, the movement speed of the index by the movement guiding unit 120 and the reading timing of the one-dimensional image by the line sensor 110 are adjusted until the authentication process is completed. (Steps S6 and S7).

  For this reason, in MFP 100 according to the present embodiment, the position at which a one-dimensional image is read from a finger and the number of one-dimensional images to be read can be constant even if authentication processing is delayed due to parallel processing. For this reason, it is possible to prevent an error in authentication processing in which a plurality of one-dimensional images are converted into two-dimensional images.

  Furthermore, in MFP 100 according to the present embodiment, a moving image whose index moves is displayed on display device 121 adjacent to line sensor 110. For this reason, the moving index can be appropriately presented to the user with a simple structure.

  In particular, the display device 121 as described above has conventionally existed in a general MFP operation panel or the like. Therefore, if line sensor 110 is arranged at a position adjacent to display device 121 and a moving image is displayed on display device 121, MFP 100 according to the present embodiment can be realized without significantly modifying a conventional product. Can do.

  In MFP 100 according to the present embodiment, as described above, when data processing unit 130 executes the authentication process, the numerical values are integrated as the parallel processing with the lowest priority, and the numerical values are detected at a constant cycle and incremented. The load state of the data processing unit 130 is detected. For this reason, it is possible to reliably detect the load state of the data processing unit 130 with a simple structure.

  In addition, the above numerical values are reset when the movement guiding unit 120 finishes moving the index. For this reason, the numerical value integrated in order to detect the load state of the data processor 130 can be reset to an appropriate timing with a simple structure.

  The present invention is not limited to the present embodiment, and various modifications are allowed without departing from the scope of the present invention. For example, in the above embodiment, an example is shown in which a moving image is displayed on the display device 121 as an index for guiding the slide of the fingertip F read by the line sensor 110.

  However, an indicator that moves even when a plurality of light emitting elements such as LEDs (Light Emitting Diodes) are arranged in a row on the side of the line sensor 110 and the light emitting elements are sequentially turned on (not shown). Can be presented to the user.

  Moreover, in the said form, it illustrated that the numerical value integrated | accumulated in order to detect the load state of the data processing part 130 is reset when the movement of a parameter | index is complete | finished. However, the above numerical values may be reset when the movement of the index is started, or may be reset at an arbitrary timing when the authentication process has not occurred.

  Furthermore, in the said form, when the fingertip F which is a finger was slid on the line sensor 110, it illustrated that the fingerprint image was produced | generated and authenticated by the several one-dimensional image read from the fingertip F.

  However, when the palm as a finger is slid on the line sensor, a palm print image may be generated from a plurality of one-dimensional images and authenticated (not shown). Similarly, the fingertip F and the vein pattern of the palm may be authenticated (not shown).
