Title: Photographing control apparatus, program and method of the same, and photographing apparatus

Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is a continuation application, filed under 35 U.S.C. §111(a), of PCT Application No. PCT/JP2007/056943, filed Mar. 29, 2007, the disclosure of which is herein incorporated in its entirety by reference. 
    
    
     FIELD 
     The present invention relates to a photographing control apparatus, a program and method of the same, and a photographing apparatus which present presentation information to draw attention of a person to be photographed and take his/her face shot properly without a hitch. 
     BACKGROUND 
     Face authentication has been conventionally known as one of biometric authentication technologies. As compared to other biometric authentications, face authentication imposes less psychological burdens on the user, whereas the face of the person to be photographed or the person to be authenticated needs to be turned to a proper direction with respect to the photographing camera. In order to take a face picture in a direction appropriate for face authentication, a method of guiding a person to be photographed so as to look to a proper direction has been known (for example, see Patent Document 1). There has also been a known method in which a flash lamp provided on a photographing apparatus is ignited to make the person to be photographed look to the front of the camera and take a face shot, utilizing the fact (key stimulus) that a visual stimulus from instantaneous strong light induces an instinctive human behavior to look to the light source (for example, see Patent Document 2). 
     For a conventional technique relevant to the present invention, it has been known to play a sound or display an image that interests the person to be photographed so that the person to be photographed looks to the camera (for example, see Patent Document 3).
     [Patent Document 1] Japanese Laid-Open Patent Publication No. 2003-141541   [Patent Document 2] Japanese Laid-Open Patent Publication No. 2005-094710   [Patent Document 3] Japanese Laid-Open Patent Publication No. 2005-164623   

     With the technology of Patent Document 1, it can be expected that the person to be photographed turns the face according to the guidance that appears on the display if the person to be photographed voluntarily takes a face shot for authentication or other purposes. It is difficult, however, to make the person to be photographed turn the face by guidance if it is undesirable to let the person to be photographed aware of the photographing in a car-mount service system or the like, or if there is no benefit for the person to be photographed to follow the guidance in such cases as photographing for surveillance purpose. 
     The technology of Patent Document 2 is considered to be effective when used against suspicious individuals. In service systems that perform authentication on the same person to be photographed repeatedly, on the other hand, the strong light will be administered to the person to be photographed each time face authentication is performed. There is another problem that the person to be photographed will get accustomed to the repetition of the same stimulus and no longer turn the face. 
     Similarly, in Patent Document 3, the person to be photographed will get accustomed to and uninterested in the presented information if there is no change. Some contrivances are thus desirably made to change the information to be presented. In such a case, a video image or the like may be used as the information to be presented to the person to be photographed. Face authentication may not be performed properly, however, if the person to be photographed gazes at the video image with a change in facial expression. In face authentication systems targeted for a plurality of persons to be photographed (such as when performing face authentication at an automated ticket gate of a station), photographing or passage will be hindered if a person to be photographed is interested in the presented information and stops. 
     SUMMARY 
     According to an aspect of the invention, an imaging control apparatus for controlling an imaging apparatus that presents presentation information and captures an image of a person, the imaging control apparatus includes: an information presentation instruction unit that refers to presentation information setting information which is designed for attracting the interest of the person, and instructs the imaging apparatus to present presentation information that the presentation information setting information; and an imaging instruction unit that instructs the imaging apparatus to capture an image of the person while the instruction presentation instruction unit instructs to present the presentation information.

     DESCRIPTION OF EMBODIMENTS 
     Hereinafter, embodiments of the present invention will be described with reference to the drawings. 
     First Embodiment 
     Initially, the overall configuration of a photographing system according to a first embodiment will be described. 
       FIG. 1  is a block diagram illustrating an example of the overall configuration of the first embodiment. The photographing system includes: a photographing apparatus  10  which can capture an image of a person to be photographed who is an authentication subject for face authentication to be performed on; a photographing control apparatus  20  which controls the photographing apparatus  10 ; a sensor  30  which detects the presence of a person to be photographed in the shooting range; a determination apparatus  40  which determines the face direction of the person to be photographed; and a face database  50  in which face data is registered. 
     The photographing apparatus  10  includes a camera  101  and an information presentation unit  102 . 
     The photographing control apparatus  20  includes a control information receiving unit  201 , a photographing instruction unit  202 , and an information presentation instruction unit  203 . 
     The camera  101  of the photographing apparatus  10  shoots the person to be photographed who is in the detection range (shooting range) of the sensor  30 . The information presentation unit  102  of the photographing apparatus  10  presents information that interests the person to be photographed. The information presentation unit  102  is installed in a position such that the person to be photographed, or the shooting subject of the camera  101 , faces to a direction appropriate for photographing when the person to be photographed looks to the information presentation unit  102 . 
     The control information receiving unit  201  of the photographing control apparatus  20  receives signals from the sensor  30  and the determination apparatus  40 , and issues instructions to the photographing instruction unit  202  and the information presentation instruction unit  203 . The photographing instruction unit  202  of the photographing control apparatus  20  receives the instruction from the control information receiving unit  201 , issues an instruction to start shooting or an instruction to stop shooting to the camera  101 , and transmits a picture taken by the camera  101  to the determination apparatus  40 . The information presentation instruction unit  203  of the photographing control unit  20  receives the instruction from the control information receiving unit  201 , and issues an instruction to start information presentation or an instruction to stop information presentation to the information presentation unit  102 . 
     The information presentation instruction unit  203  retains a plurality of pieces of presentation information, selects presentation information in order or at random, and makes the information presentation unit  102  present the presentation information selected. The presentation information may be optical information or sound information as long as it can be identified and its contents can be grasped by the person to be photographed in a short time. 
     The sensor  30  detects the presence or absence of a person (person to be photographed) in the shooting range of the camera  101 . The sensor  30  transmits a “presence” signal to the control information receiving unit  201  if a person is sensed, and transmits an “absence” signal if not. The sensor  30  may be made of any sensor such as a pyroelectric sensor, pressure sensor, and card read sensor, as long as it can detect the presence or absence of a person. When detecting the presence or absence of a person, the sensor  30  may read identification information attached to a card, for example. 
     The face database  50  contains information for identifying persons to be photographed, such as the facial images of the persons to be photographed shot by the camera  101 , as reference face data. The face data is data for authenticating certain faces, and contains facial characteristics in numerical expression. The face data may be registered in advance for authentication. 
     The determination apparatus  40  determines whether or not the face of a person to be photographed is oriented in a direction appropriate for photographing. The determination apparatus  40  also compares and collates the shot face picture with the face data stored in the face database  50 . That is, the determination apparatus  40  can function also as a face authentication apparatus. 
       FIGS. 2 and 3  are diagrams illustrating examples of the information presented by the information presentation unit  102  of the first embodiment. 
     In  FIG. 2 , the information presentation unit  102  has a display which includes a plurality of light-emitting parts  102   a.  The plurality of light-emitting parts  102   a  are individually controlled in light emission so as to display a fortune message. The display represents a plurality of fortune messages at random or in predetermined order. The camera  101  is arranged near the center of the presentation area (display) of the information presentation unit  102 . 
     In  FIG. 3 , the information presentation unit  102  is configured so that a plurality of light-emitting parts  102   a  are arranged around the camera  101  and flicker in various patterns. The patterns are selected at random or in predetermined order. Such a plurality of pieces of presentation information to be presented by the information presentation unit  102  can be selected from among the information retained in the information presentation instruction unit  203 . 
     The information presentation instruction unit  203  retains a presentation information setting table illustrated in  FIG. 4 . In  FIG. 4 , ID represents information that is read by the sensor (such as a card reader)  30  or information that is attached to face data. The genre in  FIG. 4  illustrates the presentation content selected. The presentation pattern represents the pattern that is used to select which piece of information to present in the genre selected. According to such a table, when ID  0000  is read by the sensor  30 , one of genres (types of presentation information)  1 ,  2 , and  3  is selected at random, and presentation information selected is transmitted to the information presentation unit  102  for presentation. 
     It should be noted that the first embodiment is predicated on personal authentication or multiple authentication use. Description will hereinafter be given of the personal authentication and multiple authentication according to the first embodiment. 
       FIG. 5  is a diagram illustrating an example of the personal authentication according to the first embodiment.  FIG. 6  is a diagram illustrating an example of the multiple authentication according to the first embodiment. 
     Personal authentication illustrated in  FIG. 5  is used, for example, in a service system and a surveillance system that are implemented by performing authentication on a passenger of a vehicle. Authentication on a plurality of persons to be photographed illustrated in  FIG. 6  is used, for example, in a service system and a surveillance system in which a camera is installed at a ticket gate of a station. When persons to be photographed pass the gate, information-retaining media such as an IC card are read by a sensor and face authentication is performed on the persons to be photographed. 
     In  FIG. 5 , the presentation information and the display pattern of the presentation information are set by the passenger. In  FIG. 6 , the persons to be photographed set the presentation information or type thereof in advance, and IDs for identifying the persons to be photographed are attached to their respective information-written media such as an IC card, so that predetermined types of presentation information set by the information presentation instruction unit  203  can be presented when the IDs are read by the sensor  30 . Based on the IDs for identifying the persons to be photographed, information previously set by the information presentation instruction unit may be selected and presented as presentation information depending on age, gender, occupation, etc. 
     Next, description will be given of the operation of the control information receiving unit according to the first embodiment. 
       FIG. 7  is a flowchart illustrating the operation of the control information receiving unit according to the first embodiment. In the chart, a shooting flag inside the control information receiving unit  201  indicates the state where the camera  101  is currently shooting as “ON,” and the state where the camera  101  is not shooting as “OFF.” In an initial state, the shooting flag is “OFF.” The sensor  30  outputs the “presence” signal if any person to be photographed is in the shooting coverage, and the “absence” signal if not. 
     Initially, the control information receiving unit  201  receives a signal from the sensor  30  (S 101 ). The control information receiving unit  201  determines whether or not the “presence” signal is received from the sensor  30  (S 102 ). 
     If it is determined in step S 102  that the control information receiving unit  201  receives the “presence” signal (S 102 , YES), the control information receiving unit  201  determines whether or not the shooting flag is “ON” (S 103 ). 
     If it is determined in step S 103  that the shooting flag is “OFF” (S 103 , NO), the control information receiving unit  201  transmits an information presentation start signal to the information presentation instruction unit  203  (S 104 ), transmits a photographing start signal to the photographing instruction unit  202  (S 105 ), sets the shooting flag “ON” (S 106 ), and returns to step S 101 . 
     On the other hand, if it is determined in step S 103  that the shooting flag is “ON” (S 103 , YES), the control information receiving unit  201  transmits a photographing stop signal to the photographing instruction unit  202  (S 107 ), transmits an information presentation stop signal to the information presentation instruction unit  203  (S 108 ), and returns to step S 101 . 
     If it is determined in step S 102  that the control information receiving unit  201  receives the “absence” signal (S 102 , NO), the control information receiving unit  201  transmits the photographing stop signal to the photographing instruction unit  202  (S 109 ), transmits the information presentation stop signal to the information presentation instruction unit  203  (S 110 ), and resets the shooting flag “OFF” (S 111 ). 
     In the flowchart, NO in step S 103  indicates the state in which photographing and information presentation are stopped, from which the control information receiving unit  201  starts photographing and information presentation. YES in step S 103  and NO in step S 102  indicate the state where photographing and information presentation are completed, and the control information receiving unit  201  stops photographing and information presentation. The operation of step S 103  allows the control information receiving unit  201  to stop photographing and information presentation even if a person remains in front of the sensor  30 , so that the same person will not be photographed repeatedly. Through the loop of the operation illustrated in  FIG. 7 , the photographing control apparatus  20  can make the photographing apparatus  10  photograph persons in succession for multiple authentication such as when authenticating persons successively in such a place as a ticket gate of a station. 
     Next, description will be given of the operation of the determination apparatus according to the first embodiment. 
       FIG. 8  is a flowchart illustrating the operation of the determination apparatus according to the first embodiment. 
     Initially, the determination apparatus  40  determines whether or not there is any picture input from the camera  101  through the photographing instruction unit  202 , based on an instruction from the photographing instruction unit  202  (S 501 ). 
     If it is determined in step S 501  that there is a picture input (S 501 ), the determination apparatus  40  determines whether or not the face of the person to be photographed seen in the input picture falls within a range of direction (S 502 ). 
     If it is determined in step S 502  that the direction of the face of the person to be photographed falls within a predetermined range (appropriate range) (S 502 , YES), the determination apparatus  40  transmits photographing completion information to the control information receiving unit  201  (S 503 ). The determination apparatus  40  determines again whether or not there is any picture input (S 501 ), collates the input picture with the data in the face database  50  (S 504 ), and outputs the result of determination (identification) (S 505 ). 
     On the other hand, if it is determined in step S 502  that the direction of the face of the person to be photographed in the input picture does not fall within the range (S 502 , NO), or if it is determined in step S 501  that there is no picture input from the photographing instruction unit  202  (S 501 , NO), the same operation is repeated. 
     As described above,  FIG. 8  illustrates the operation when the determination apparatus  40  performs collation and outputs the result of collation after the completion of the photographing. 
       FIG. 9  is a flowchart illustrating the operation when the determination apparatus outputs the photographing completion information after the output of the result of determination (identification). The operation of step S 501  and step  5502 , NO, is the same as in  FIG. 8 , and description thereof will thus be omitted. The operation after step S 502 , YES, will be given below. 
     If it is determined in step S 502  that the direction of the face of the person to be photographed falls within the range (S 502 , YES), the determination apparatus  40  collates the input picture with the data in the face database  50  (S 503   a ), outputs the result of determination (identification) (S 504   a ), transmits the photographing completion information to the control information receiving unit  201  (S 505   a ), and returns to step S 501 . 
     Next, description will be given of the operation of the photographing instruction unit according to the first embodiment. 
       FIG. 10  is a flowchart illustrating the operation of the photographing instruction unit according to the first embodiment. 
     Initially, the photographing instruction unit  202  determines whether or not the photographing start signal is received from the control information receiving unit  201  (S 201 ). 
     If in step S 201  the photographing instruction unit  202  receives the photographing start signal (S 201 , YES), the photographing instruction unit  202  instructs the camera  101  to perform shooting (S 202 ), transmits the shot picture to the determination apparatus  40  (S 203 ), and determines whether or not the stop signal is received (S 204 ). 
     If in step S 204  the photographing instruction unit  202  receives the photographing stop signal (S 204 , YES), the photographing instruction unit  202  makes the camera  101  stop shooting (S 205 ), and returns to step S 201 . 
     On the other hand, if the photographing instruction unit  202  does not receive the photographing stop signal (S 204 , NO), the photographing instruction unit  202  makes the camera  101  continue shooting (S 202 ). 
     If it is determined in step S 201  that the photographing instruction unit  202  does not receive the photographing start signal (S 201 , NO), the photographing instruction unit  202  repeats the same operation (S 201 ). 
     Next, the operation of the information presentation instruction unit of the first embodiment will be described with reference to the flowchart of  FIG. 11 . 
     Initially, the information presentation instruction unit  203  makes the information presentation unit  102  stop information presentation (S 301 ), in which state the information presentation instruction unit  203  determines whether or not a presentation start signal is received from the control information receiving unit  201  (S 302 ). 
     If it is determined in step S 302  that the information presentation instruction unit  203  receives the presentation start signal (S 302 , YES), the information presentation instruction unit  203  resets an information presentation flag it retains “OFF” (S 303 ), and determines whether or not the information presentation flag is “ON” (S 304 ). 
     If it is determined in step S 304  that the information presentation flag is “OFF” (S 304 , NO), the information presentation instruction unit  203  sets the information presentation flag “ON” (S 305 ), selects presentation contents from a plurality of pieces of presentation information it retains in predetermined order or at random (S 306 ), and makes the information presentation unit  102  present the presentation information selected (S 307 ). The information presentation instruction unit  203  then determines whether or not the stop signal is received (S 308 ). 
     If it is determined in step S 308  that the information presentation instruction unit  203  receives the stop signal (S 308 , YES), the information presentation instruction unit  203  makes the information presentation unit  102  stop information presentation (S 301 ). 
     On the other hand, if it is determined in step S 308  that the information presentation instruction unit  203  does not receive the stop signal (S 308 , NO), the information presentation instruction unit  203  determines whether or not the information presentation flag is “ON” (S 304 ). 
     If in step S 304  the information presentation flag is “ON” (S 304 , YES), the information presentation instruction unit  203  determines whether or not the stop signal is received (S 308 ). 
     Now, if in step S 302  the information presentation instruction unit  203  does not receive the presentation start signal from the control information receiving unit  201  (S 302 , NO), the information presentation instruction unit  203  keeps the information presentation unit  102  stopping information presentation (S 301 ). 
     Next, description will be given of the operation when the photographing control apparatus selects presentation contents. 
       FIG. 12  is a flowchart illustrating the overall operation when presentation information is selected according to the first embodiment. In the chart, if the sensor  30  reads information that identifies an individual, ID shall be additional information that is read by the sensor  30 . If the photographing control apparatus  20  is targeted for a certain user, ID shall be information that is preset for selecting a display pattern. 
     Initially, when a signal is input from the sensor  30  (S 401 , YES), the control information receiving unit  201  transmits ID to the information presentation instruction unit  203  (S 402 ). In step S 402 , the information presentation instruction unit  203  may transmit user-preset information as the ID. 
     Receiving the ID, the information presentation instruction unit  203  refers to the presentation information setting table to determine a presentation pattern from the ID (S 403 ), determines presentation information based on the presentation pattern and the set genre (S 404 ), and transmits the presentation contents to the information presentation unit  102  (S 405 ). 
     Receiving the presentation contents, the information presentation unit  102  presents the information. The camera  101  starts shooting (S 406 ). 
     After a lapse of predetermined time or at the completion of photographing or both photographing and identification, the control information receiving unit  201  transmits stop information to the photographing instruction unit  202  and the information presentation instruction unit  203  (S 407 ). The photographing instruction unit  202  makes the camera  101  stop shooting, and the information presentation instruction unit  203  makes the information presentation unit  102  stop presentation (S 408 ). The procedure returns to step S 401 . 
     Second Embodiment 
     In the first embodiment, the determination apparatus  40  and the face database  50  are provided outside the photographing control apparatus  20 . In a second embodiment, such components may be provided inside the photographing control apparatus as illustrated in  FIG. 13 . 
     More specifically, the second embodiment differs from the first embodiment in that a determination unit  204  having the same function as that of the determination apparatus  40  is arranged inside the photographing control apparatus  20  instead of the determination apparatus  40 , along with the face database  50 . In operation, a difference from the first embodiment consists in that the operation that has been performed by the determination apparatus  40  in the first embodiment is performed by the determination unit  204  in the second embodiment. 
     Third Embodiment 
       FIG. 14  is a block diagram illustrating an example of the overall configuration of a third embodiment. 
     The third embodiment differs from the second embodiment in that a picture recording unit  205  is newly provided. The picture recording unit  205  stores pictures transmitted from the photographing instruction unit  202 . Whether or not to store pictures is determined by the determination unit  204  when performing face authentication. 
     In operation, a difference from the second embodiment consists in that the determination unit  204  outputs the result of determination of face authentication and determines whether or not to make the picture recording unit  205  store the picture transmitted to the picture recording unit  205  in step  5505  of  FIG. 8  or in step S 504   a  of  FIG. 9 . Another difference from the second embodiment lies in that the photographing instruction unit  202  transmits the picture to the determination unit  204  and the picture recording unit  205  in step  5203  of  FIG. 10 . 
     The determination unit  204  will not store the picture into the picture recording unit  205  if the person to be photographed is registered in the face database, and stores the picture into the picture recording unit  205  only if the person to be photographed is not registered in the face database. Since the pictures of non-registrants are stored into the picture recording unit  205 , it is possible to identify a non-registrant, for example, when the non-registrant impersonates a registrant and attempts face authentication. The criterion by which the determination unit  204  determines whether or not to store may be set in advance, or may be freely configured. 
     Fourth Embodiment 
       FIG. 15  is a block diagram illustrating an example of the overall configuration of a fourth embodiment. 
     The fourth embodiment differs from the first embodiment in that a presentation information receiving unit  206  is newly provided. The presentation information receiving unit  206  is connected to a network. The presentation information receiving unit  206  downloads latest information that the person to be photographed can recognize in a short time, such as a weather forecast, traffic information, exchange quotations, current prices at an auction, and sports scores, over the network, and transmits the information to the information presentation instruction unit  203 . Reading presentation information from exterior makes it possible to present not only presentation information that is registered in advance and has limited display patterns, such as fortune messages and flicker patterns, but also a wider range of information to interest the person to be photographed. 
       FIG. 16  is a latest presentation information table which the presentation information receiving unit according to the fourth embodiment retains. 
     The presentation information receiving unit  206  retains downloaded information, the update date and time, and the corresponding genre of the downloaded information in association with each other as illustrated in  FIG. 16 . The information to be input to the presentation information receiving unit  206  may be input by the user or administrator. 
     In operation, a difference from the first embodiment consists in that the information presentation instruction unit  203  constantly accepts inputs from the presentation information receiving unit  206 . 
       FIG. 17  is a flowchart illustrating the operation of the information presentation instruction unit according to the fourth embodiment. 
     The information presentation instruction unit  203  initially makes the information presentation unit  102  stop information presentation (S 601 ), in which state the information presentation instruction unit  203  acquires presentation information from the presentation information receiving unit  206  (S 602 ). If the information presentation instruction unit  203  receives the start signal from the control information receiving unit  201  (S 603 , YES), the information presentation instruction unit  203  resets the information presentation flag it retains “OFF” (S 604 ), and determines whether or not the information presentation flag is “ON” (S 605 ). 
     If it is determined in step S 605  that the information presentation flag is “OFF” (S 605 , NO), the information presentation instruction unit  203  sets the information presentation flag “ON” (S 606 ). The information presentation instruction unit  203  selects presentation information from a plurality of pieces of presentation information it retains, including the presentation information acquired from the presentation information receiving unit  206 , in predetermined order or at random (S 607 ), and makes the information presentation unit  102  present the presentation information selected (S 608 ). The information presentation instruction unit  203  then determines whether or not the stop signal is received (S 609 ). 
     As has been described in the first embodiment, the information presentation instruction unit may select presentation information depending on age, gender, occupation, and the like based on the ID of the person to be photographed if the ID is available. In such a case, presentation priority may be given between genres based on the ID. For example, 1) stock prices and 2) weather forecasts are presented in this order to working persons of age 30s to 50s to be photographed. 
     If it is determined in step S 609  that the information presentation instruction unit  203  receives the stop signal (S 609 , YES), the information presentation instruction unit  203  makes the information presentation unit  102  stop information presentation (S 601 ). 
     On the other hand, if the information presentation instruction unit  203  does not receive the stop signal (S 609 , NO), the information presentation instruction unit  203  returns to step S 605 . 
     If in step S 605  the information presentation flag is “ON” (S 605 , YES), the information presentation instruction unit  203  proceeds to step S 609 .
