[0011] Hereinafter, embodiments of an information processing device, an information processing system, an information processing method, and a program will be described with reference to the drawings. [1: First Embodiment]

[0012] An information processing device, an information processing system, an information processing method, and a program according to a first embodiment will be described below. Hereinafter, an information processing device, an information processing system, an information processing method, and a program according to a first embodiment will be described using an information processing device 1 according to this disclosure.

[0013] An information processing device 1 according to this disclosure will be described with reference to Figures 1 and 2. Figure 1 is a block diagram showing the configuration of the information processing device 1 according to this disclosure. Figure 2 is a schematic diagram for explaining an overview of the operation of the information processing device 1 according to this disclosure. As shown in Figure 1, the information processing device 1 includes a first camera C1, a second camera C2, and a third camera C3.

[0014] The first camera C1 may be a camera capable of capturing light in the visible wavelength range (a so-called visible light camera). Alternatively, the first camera C1 (camera CAM) may be a camera capable of capturing light in the near-infrared wavelength range (a so-called near-infrared camera). Furthermore, the image captured by the first camera C1 may be a concept that includes video.

[0015] The second camera C2 and the third camera C3, the camera CAM, may be a camera capable of capturing light in the near-infrared wavelength range (a so-called near-infrared camera). Alternatively, the second camera C2 and the third camera C3 may be a camera capable of capturing light in the visible wavelength range (a so-called visible light camera). Furthermore, the images captured by the second camera C2 and the third camera C3 may be conceptually inclusive of video.

[0016] The first camera C1 captures an image including a first target and a second target. Fig. 2 shows an example of an image I captured by the first camera C1. As shown in Fig. 2, the image I includes a first target TP1 and a second target TP2.

[0017] The second camera C2 captures an image of the iris of the first target and acquires an iris image including the iris of the first target. As illustrated in Fig. 2, the second camera C2 captures an image of the iris of the first target TP1 based on the image I. The second camera C2 may capture an image of a location to be captured (i.e., the iris of the first target TP1) determined based on the image I, for example.

[0018] The third camera C3 captures an image of the iris of the second target and acquires an iris image including the iris of the second target. As illustrated in Fig. 2, the third camera C3 captures an image of the iris of the second target TP2 based on the image I. The third camera C3 may capture an image of a location to be captured (i.e., the iris of the second target TP2) determined based on the image I. [Technical Effects of the Information Processing Device 1]

[0019] In the information processing device 1 according to the present disclosure, the second camera C2 captures an image of the iris of the first target and the third camera C3 captures an image of the iris of the second target based on an image including a first target and a second target, so that even in a scene where there are multiple targets, an appropriate iris image of the target can be obtained. [2: Second Embodiment]

[0020] A second embodiment of an information processing device, an information processing system, an information processing method, and a program will be described with reference to FIGS. 3 to 6. Hereinafter, the second embodiment of an information processing device, an information processing system, an information processing method, and a program will be described using an information processing device 2. Note that, for the second embodiment, descriptions that overlap with the description of the first embodiment will be omitted as appropriate. [2-1: Configuration of Information Processing Device 2]

[0021] Fig. 3 is a schematic diagram showing an overview of an information processing device 2 according to this disclosure. Fig. 4 is a block diagram showing the configuration of an information processing device 1 according to this disclosure.

[0022] As shown in FIG. 3 , the information processing device 2 is applied to a location where a first target TP1 and a second target TP2 can move side by side. This location where the first target TP1 and the second target TP2 can move side by side is referred to as a lane L. The destinations of the first target TP1 and the second target TP2 may be located at the end of the direction of the arrows illustrated in FIG. 3 . The first target TP1 and the second target TP2 may be guided to move in the direction of the arrows illustrated in FIG. 3 . The first target TP1 and the second target TP2 move generally in the longitudinal direction of the lane L. The direction in which the first target TP1 and the second target TP2 move may be referred to as the "movement direction." In the lane L, the first target TP1 and the second target TP2 can move side by side in a direction other than the movement direction. In the lane L, the first target TP1 and the second target TP2 may be able to move side by side in the short direction of the lane L (referred to as the "width direction of the lane L"). The width of the lane L may be approximately twice the width of the passageway through which an average adult can move.

[0023] 3, the information processing device 2 includes a first camera C1, a second camera C2, and a third camera C3, which correspond to the first camera C1, the second camera C2, and the third camera C3 in the first embodiment, respectively.

[0024] The first camera C1 captures an image of a space in which the first target TP1 and the second target TP2 can move side by side. The first camera C1 may capture an image of a space in which the first target TP1 and the second target TP2 can move side by side in the width direction of the lane L. As shown in FIG. 3 , the first camera C1 may be provided in a location that provides a bird's-eye view of the first target TP1 and the second target TP2 moving side by side. The first camera C1 may be provided to capture an image of a predetermined area in which the first target TP1 and the second target TP2 can move side by side. The predetermined area may include an area that can be captured by at least one of the second camera C2 and the third camera C3. The predetermined area may include an area within a predetermined distance from at least one of the second camera C2 and the third camera C3. The predetermined area may include the lane L from the position where the second camera C2 and the third camera C3 are provided to a predetermined position behind them in the direction of movement.

[0025] The second camera C2 may be provided at one end in a direction different from the direction of movement. For example, the second camera C2 may be provided at one end in a horizontal direction perpendicular to the direction of movement. In other words, the second camera C2 may be provided at one end in the width direction of the lane L. The second camera C2 may be provided at the other end in the direction different from the direction of movement. For example, the third camera C3 may be provided at the other end in the horizontal direction perpendicular to the direction of movement. In other words, the third camera C3 may be provided at the other end in the width direction of the lane L. In other words, it may be said that there is a space between the second camera C2 and the third camera C3 in which the first target TP1 and the second target TP2 can move side by side.

[0026] The second camera C2 may capture an image of the iris of a target moving on one side of the width direction of the lane L from one end side of the lane L. In the example shown in Figure 3, the second camera C2 may be provided on the right side of the lane L as seen from the target (the left side of the lane L as seen from the first camera C1). Also, in the example shown in Figure 3, the second camera C2 may capture an image of the iris of the first target TP1 moving on the right side of the lane L from the right side of the lane L as seen from the target.

[0027] The third camera C3 may capture an image of the iris of a target moving on the other side of the width direction of the lane L from the other end side of the lane L. In the example shown in Figure 3, the third camera C3 may be provided on the left side of the lane L as seen from the target (the right side of the lane L as seen from the first camera C1). Also, in the example shown in Figure 3, the third camera C3 may capture an image of the iris of the second target TP2 moving on the left side of the lane L from the left side of the lane L as seen from the target.

[0028] 3 illustrates an example in which the first camera C1 is installed in a location where it can overlook the first target TP1 and the second target TP2, but the location in which the first camera C1 is installed is not limited to this. The first camera C1 may be installed near at least one of the second camera C2 and the third camera C3. For example, the first camera C1 may be installed in the same housing as the second camera C2. Furthermore, the first camera C1 may be installed in the same housing as the third camera C3. A plurality of first cameras C1 may be installed. That is, the first camera C1 may be installed near the second camera C2 and near the third camera C3.

[0029] The first camera C1 that captures an image for determining the camera that will capture the image of the subject's iris may be different from the first camera C1 that captures an image for identifying the position of the subject's iris. For example, the first camera C1 that captures an image for identifying the position of the subject's iris may be provided in a location that is in front of the direction of movement and that is noticeable to the subject. In other words, the first camera C1 that captures an image for identifying the position of the subject's iris may be provided in a conspicuous location.

[0030] 4, the information processing device 2 includes a calculation device 21, a storage device 22, a communication device 23, an input device 24, and an output device 25. The calculation device 21, the storage device 22, the communication device 23, the input device 24, and the output device 25 may be connected via a data bus 26. The calculation device 21 may include, for example, at least one of a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), an FPGA (Field Programmable Gate Array), a TPU (Tensor Processing Unit), and a quantum processor.

[0031] The storage device 22 may include, for example, at least one of a RAM (Random Access Memory), a ROM (Read Only Memory), a hard disk device, a magneto-optical disk device, an SSD (Solid State Drive), and an optical disk array. In other words, the storage device 22 may include a non-transitory recording medium. The storage device 22 is capable of storing desired data. For example, the storage device 22 may temporarily store a computer program executed by the arithmetic device 21. The storage device 22 may temporarily store data that is temporarily used by the arithmetic device 21 when the arithmetic device 21 is executing a computer program.

[0032] The communication device 23 may be capable of communicating with devices external to the information processing device 2. The communication device 23 may perform wired communication or wireless communication.

[0033] The input device 24 is a device capable of accepting information input to the information processing device 2 from outside. The input device 24 may include an operation device (e.g., a keyboard, a mouse, a touch panel, etc.) that can be operated by a user of the information processing device 2. The input device 24 may include a recording medium reading device that can read information recorded on a recording medium that is detachable from the information processing device 2, such as a USB (Universal Serial Bus) memory. Note that when information is input to the information processing device 2 via the communication device 23 (in other words, when the information processing device 2 obtains information via the communication device 23), the communication device 23 may function as an input device.

[0034] The output device 25 is a device capable of outputting information to the outside of the information processing device 2. The output device 25 may output visual information such as text or images, auditory information such as sound, or tactile information such as vibration, as the information. The output device 25 may include, for example, at least one of a display, a speaker, a printer, and a vibration motor. The output device 25 may be capable of outputting information to a recording medium detachable from the information processing device 2, such as a USB memory. Note that when the information processing device 2 outputs information via the communication device 23, the communication device 23 may function as the output device.

[0035] The arithmetic device 21 in this embodiment has a determination unit 211 as a logically realized functional block or as a physically realized processing circuit. Note that the determination unit 211 may be realized in a form in which a logical functional block and a physical processing circuit (i.e., hardware) are mixed. When the determination unit 211 is a functional block, the determination unit 211 may be realized by the arithmetic device 21 executing a predetermined computer program.

[0036] The arithmetic device 21 may acquire (in other words, read) the predetermined computer program from the storage device 22. The arithmetic device 21 may read the predetermined computer program stored in a computer-readable, non-transitory recording medium using a recording medium reading device (not shown) provided in the information processing device 2. The arithmetic device 21 may acquire (in other words, download or read) the predetermined computer program from a device (not shown) external to the information processing device 2 via the communication device 23. Note that the recording medium for recording the predetermined computer program executed by the arithmetic device 21 may be at least one of an optical disk, a magnetic medium, a magneto-optical disk, a semiconductor memory, and any other medium capable of storing a program. [2-2: Information Processing Method Executed by Information Processing Device 2]

[0037] The information processing device 2 is configured as a device for acquiring an iris image. An information processing method executed by the information processing device 2 will be described with reference to Fig. 5 and Fig. 6. Fig. 5 is a flowchart showing the flow of the information processing method executed by the information processing device 2. Fig. 6 is a schematic diagram showing an overview of the information processing method executed by the information processing device 2.

[0038] As shown in Fig. 5, the first camera C1 captures an image including a first target and a second target (step S21). Fig. 6(a) illustrates an example of an image I captured by the first camera C1. As illustrated in Fig. 6(a), the image I includes a first target TP1 and a second target TP2.

[0039] The determination unit 211 determines the target to be imaged by the second camera C2 and the target to be imaged by the third camera C3 based on the image (step S22). The determination unit 211 may determine the target to be imaged by the second camera C2 and the target to be imaged by the third camera C3 based on at least one of the positional relationship between the first target and the second target included in the image and the distance of each of the first target and the second target to the first camera C1.

[0040] According to the image I illustrated in FIG. 6A, the first target TP1 is located to the left of the second target TP2 on the lane L as viewed from the first camera C1. Furthermore, the second target TP2 is located to the right of the first target TP1 on the lane L as viewed from the first camera C1. In this case, the determination unit 211 determines that the second camera C2, which is provided on the left side of the lane L as viewed from the first camera C1, will capture an image of the first target TP1 located on the left side. Furthermore, the determination unit 211 determines that the third camera C3, which is provided on the right side of the lane L as viewed from the first camera C1, will capture an image of the second target TP2 located on the right side. In other words, the determination unit 211 determines, based on the image, the first target to be captured by the second camera C2 and the second target to be captured by the third camera C3.

[0041] Furthermore, for example, when the first camera C1 is provided near the second camera C2, the determination unit 211 may determine that, of the first target TP1 and the second target TP2, the target that is closer to the first camera C1 is the target to be imaged by the second camera C2, and the target that is farther to the first camera C1 is the target to be imaged by the third camera C3. Furthermore, when the first camera C1 is provided near the third camera C3, the determination unit 211 may determine that, of the first target TP1 and the second target TP2, the target that is closer to the first camera C1 is the target to be imaged by the third camera C3, and the target that is farther to the first camera C1 is the target to be imaged by the second camera C2.

[0042] The second camera C2 images the iris of the first target TP1 and acquires an iris image including the iris of the first target TP1. The third camera C3 images the iris of the second target TP2 and acquires an iris image including the iris of the second target TP2 (step S23). The second camera C2 images the iris of the first target TP1 based on the image I. The second camera C2 may, for example, image the location to be imaged (i.e., the iris of the first target TP1) determined based on the image I. The third camera C3 images the iris of the second target TP2 based on the image I. The third camera C3 may, for example, image the location to be imaged (i.e., the iris of the second target TP2) determined based on the image I. [2-3: Modifications]

[0043] 6(b), the determination unit 211 may divide the image I along a vertical line L, determine that the second camera C2 will capture an image of a first target TP1 included in one divided image IL, and determine that the third camera C3 will capture an image of a second target TP2 included in the other divided image IR. The determination unit 211 may divide the image I in the vertical direction along the vertical line L so that the first target TP1 is included in one image IL and the second target TP2 is included in the other image IR.

[0044] In addition, if the image contains one subject, the determination unit 211 may divide the image into left and right halves in the middle, and determine that the second camera C2 will capture the subject if the subject is included in the left image, and that the third camera C3 will capture the subject if the subject is included in the right image.

[0045] In the second embodiment, the information processing device 2 is described as having the first camera C1, the second camera C2, and the third camera C3. However, the information processing device 2 does not have to have the first camera C1, the second camera C2, and the third camera C3. In this case, the information processing device 2 may communicate with the first camera C1, the second camera C2, and the third camera C3 via the communication device 23 and perform the determination operation. [2-4: Technical Effects of the Information Processing Device 2]

[0046] The information processing device 2 according to this disclosure determines the target to be imaged by each of the second camera and the third camera based on at least one of the positional relationship between two targets included in the image captured by the first camera and the distances of the two targets to the camera, so that each of the second camera and the third camera can appropriately image the irises of the targets. [3: Third Embodiment]

[0047] A third embodiment of an information processing device, an information processing system, an information processing method, and a program will be described with reference to Figures 7 to 9. Hereinafter, the third embodiment of an information processing device, an information processing system, an information processing method, and a program will be described using an information processing system S including an information processing device 3 according to this disclosure. Note that, for the third embodiment, descriptions that overlap with the descriptions of the first and second embodiments will be omitted as appropriate. Also, in the drawings, parts common to the second embodiment are indicated by the same reference numerals. [3-1: Configuration of Information Processing System S]

[0048] As shown in FIG. 7 , the information processing system S includes an information processing device 3, a face camera FC, a first iris camera IC1, and a second iris camera IC2. The face camera FC, the first iris camera IC1, and the second iris camera IC2 correspond to the first camera C1, the second camera C2, and the third camera C3, respectively, in the first and second embodiments described above. That is, the information processing device 3 according to the third embodiment does not need to include the first camera C1, the second camera C2, and the third camera C3. The information processing device 3 only needs to be able to communicate with the face camera FC, the first iris camera IC1, and the second iris camera IC2 included in the information processing system S. The information processing device 3 may communicate with the face camera FC, the first iris camera IC1, and the second iris camera IC2 via a communication device 23. The information processing device 3 may communicate with the face camera FC, the first iris camera IC1, and the second iris camera IC2 wirelessly or via wired communication.

[0049] As shown in Fig. 7, the face camera FC, like the first camera C1, captures an image of a space in which the first target TP1 and the second target TP2 can move side by side. As with the first camera C1, the face camera FC may be installed in a location that provides a bird's-eye view of the first target TP1 and the second target TP2 moving side by side, as shown in Fig. 7. Furthermore, the image captured by the face camera FC may be a concept that includes video.

[0050] The first iris camera IC1 may be provided at one end in a direction different from the direction of movement, similar to the second camera C2, and the second iris camera IC2 may be provided at the other end in a direction different from the direction of movement, similar to the third camera C3.

[0051] The first iris camera IC1 may capture an image of the iris of a target moving on one side of the width direction of the lane L from one end side of the lane L. In the example shown in Fig. 7, the first iris camera IC1 may be provided on the right side of the lane L as seen from the target (the left side of the lane L as seen from the face camera FC). Also, in the example shown in Fig. 7, the first iris camera IC1 may capture an image of the iris of the first target TP1 moving on the right side of the lane L from the right side of the lane L as seen from the target. Also, the image captured by the first iris camera IC1 may be a concept that includes a moving image.

[0052] The second iris camera IC2 may capture an image of the iris of a target moving on the other side of the width direction of the lane L from the other end side of the width direction of the lane L. In the example shown in Fig. 7, the second iris camera IC2 may be provided on the left side of the lane L as seen from the target (the right side of the lane L as seen from the face camera FC). Also, in the example shown in Fig. 7, the second iris camera IC2 may capture an image of the iris of the second target TP2 moving on the left side of the lane L from the left side of the lane L as seen from the target. Also, the image captured by the second iris camera IC2 may be a concept that includes a moving image.

[0053] Like the first camera C1, the face camera FC may be provided near at least one of the first iris camera IC1 and the second iris camera IC2. A plurality of face cameras FC may be provided. That is, a face camera FC may be provided near the first iris camera IC1 and near the second iris camera IC2.

[0054] The information processing system S may be applied to determining whether or not a subject is permitted to enter a restricted area and managing entry to the restricted area. The restricted area may be an area into which a subject who has been successfully authenticated and confirmed to be the person in question may enter. The restricted area may be an area in front of the end point B of the lane L in the direction of movement. Therefore, the information processing system S may be configured to authenticate a subject in the lane L behind the end point B of the lane L in the direction of movement.

[0055] 8, the arithmetic device 21 included in the information processing device 3 may have an imaging control unit 311, an authentication unit 312, and an authentication result notification unit 313 as logically realized functional blocks or as physically realized processing circuits. The imaging control unit 311 may have a face image acquisition unit 3111 and a determination unit 3112. The determination unit 3112 corresponds to the determination unit 211 in the second embodiment described above. [3-2: Information Processing Method Executed by Information Processing Device 3]

[0056] The information processing device 3 is configured as a device for acquiring an iris image and performing authentication using the iris image (iris authentication). An information processing method executed by the information processing device 3 will be described with reference to Fig. 9. Fig. 9 is a flowchart showing the flow of the information processing method executed by the information processing device 3.

[0057] 9 , the facial image acquisition unit 3111 acquires an image including a first target TP1 and a second target TP2 (step S31). The facial image acquisition unit 3111 may acquire the image from a facial camera FC. Based on the image, the determination unit 3112 determines the first iris camera IC1 that captures the iris of the first target TP1 and the second iris camera IC2 that captures the iris of the second target TP2 (step S32).

[0058] The first iris camera IC1 captures an image of the iris of the first target TP1 to obtain an iris image 1 including the iris of the first target TP1. The second iris camera IC2 captures an image of the iris of the second target TP2 to obtain an iris image 2 including the iris of the second target TP2. The authentication unit 312 obtains the iris image 1 from the first iris camera IC1 and the iris image 2 from the second iris camera IC2 (step S33).

[0059] The authentication unit 312 performs authentication using iris image 1 and authentication using iris image 2 (step S34). The authentication unit 312 may calculate a matching score by comparing the iris image with a pre-registered iris image. The matching score may mean a value indicating the degree of match between the acquired iris image and the pre-registered iris image. The matching score may mean a value indicating the degree of match between a feature extracted from the iris image and a pre-registered feature. Therefore, the authentication unit 312 may calculate the matching score by comparing the feature extracted from the iris image with a pre-registered feature.

[0060] The authentication unit 312 determines whether the iris authentication has been successful. In iris authentication, if the matching score is equal to or greater than a predetermined threshold, it is determined that the subject is a person who has been registered in advance. The authentication unit 312 may determine that the iris authentication has been successful if the matching score exceeds the predetermined threshold. In this case, the authentication unit 312 may determine that the iris authentication has failed if the matching score is smaller than the predetermined threshold. Note that if the matching score is equal to the predetermined threshold, it may be treated as including either case.

[0061] In addition to iris authentication, the authentication unit 312 may also perform authentication using a facial image (face authentication). The authentication unit 312 may perform face authentication by comparing a facial image of a target included in an image captured by the face camera FC with a facial image of a target registered in advance. In other words, the authentication unit 312 may perform multimodal authentication.

[0062] The authentication result notifying unit 313 notifies the first target TP1 and the second target TP2 of the authentication result (step S35). The authentication result notifying unit 313 may notify the authentication result at the end point B of the lane L.

[0063] For example, a gate may be provided at end point B of lane L. For example, an openable / closable flap may be provided at end point B of lane L. The authentication result notifying unit 313 may notify the target that authentication of the target has been successful by opening a closed gate. Furthermore, the authentication result notifying unit 313 may notify the target that authentication of the target has failed by closing an open gate. Furthermore, for example, the authentication result notifying unit 313 may notify the target of success or failure of authentication of the target by illuminating the area around the target's feet with a different color depending on whether authentication has been successful or not.

[0064] A display device may be provided at the end point B of the lane L. In this case, the authentication result notifying unit 313 may notify the target of the success or failure of the authentication of the target by displaying information indicating the success or failure of the authentication of the target on the display device.

[0065] Furthermore, the authentication result notification unit 313 may display on the display device an action to be taken by the subject depending on whether the authentication was successful or not. For example, the action to be taken by a subject who has been successfully authenticated may be to enter the restricted area. For example, the action to be taken by a subject who has failed authentication may be to repeat the movement within lane L. For example, the action to be taken by a subject who has failed authentication may be to undergo an examination by an examiner who examines whether or not the subject is allowed to enter the restricted area.

[0066] A security guard may be stationed at the end point B of the lane L. The security guard may call out to a subject who does not perform an action according to the authentication result notified by the authentication result notifying unit 313.

[0067] In the third embodiment, the information processing system S includes an information processing device 3, a face camera FC, a first iris camera IC1, and a second iris camera IC2, and realizes the above-described information processing operation. However, the above-described information processing operation may be realized in other forms. For example, the information processing system S may include a first information processing device including an imaging control unit 311, a face camera FC, a first iris camera IC1, and a second iris camera IC2, and a second information processing device including an authentication unit 312 and an authentication result notification unit 313. In this case, the first information processing device and the second information processing device may each include a calculation device, a storage device, a communication device, an input device, and an output device corresponding to the calculation device 21, the storage device 22, the communication device 23, the input device 24, and the output device 25, respectively. In addition, the first information processing device in this case may correspond to the information processing device 2 according to the second embodiment. In addition, the information processing device 3 may include a face camera FC, a first iris camera IC1, and a second iris camera IC2. These variations are also applicable to the other embodiments described below. [3-3: Technical Effects]

[0068] The information processing device 3 according to this disclosure can perform authentication using an iris image 1 including the iris of a first target that is appropriately captured by a first iris camera IC1, and authentication using an iris image 2 including the iris of a second target that is appropriately captured by a second iris camera IC2. [4: Fourth Embodiment]

[0069] A fourth embodiment of an information processing device, an information processing system, an information processing method, and a program will be described with reference to FIGS. 10 to 12. Hereinafter, the fourth embodiment of an information processing device, an information processing system, an information processing method, and a program will be described using an information processing system Sa including an information processing device 4 according to this disclosure. Note that, for the fourth embodiment, descriptions that overlap with the descriptions of the first to third embodiments will be omitted as appropriate. Also, in the drawings, parts common to the second and third embodiments are indicated by the same reference numerals. [4-1: Configuration of information processing system Sa]

[0070] 10, the information processing system Sa includes an information processing device 4, a face camera FC, a first iris camera IC1, and a second iris camera IC2. The information processing device 4 may communicate with the face camera FC, the first iris camera IC1, and the second iris camera IC2 via a communication device 23. As shown in FIG. 10, the arithmetic device 21 included in the information processing device 4 may have, as logically realized functional blocks or as physically realized processing circuits, an imaging control unit 311, an authentication unit 312, an authentication result notification unit 313, as well as a tracking unit 414 and an identification unit 415. [4-2: Information Processing Method Executed by Information Processing Device 4]

[0071] The information processing device 4 is configured as a device for sequentially acquiring iris images from a target moving in a movement direction and sequentially performing iris authentication. An information processing method executed by the information processing device 4 will be described with reference to Figs. 11 and 12. Fig. 11 is a flowchart showing the flow of the information processing method executed by the information processing device 4. Fig. 1c is a schematic diagram showing an overview of the information processing method executed by the information processing device 4. Note that the series of information processing methods executed by the information processing device 4, which will be described with reference to Figs. 11 and 12, may be operations related to a first target and a second target.

[0072] As shown in FIG. 11 , the facial image acquisition unit 3111 acquires an image from the facial camera FC (step S31). The facial camera FC may be configured to capture an image of the lane L (this area is referred to as the "tracking area") from the position where the second camera C2 and the third camera C3 are installed to a predetermined position behind in the direction of movement. In this case, the facial image acquisition unit 3111 may be said to acquire an image of the tracking area. The camera CAM may be installed at a height of, for example, 2.5 meters. If the facial camera FC is installed at a height higher than the average human height, the image captured by the facial camera FC is likely to include the target's head area and upper body area. The head area and upper body area may be suitable areas for the target's tracking area. Furthermore, if multiple facial cameras FC are installed, the facial image acquisition unit 3111 may acquire images from the multiple facial cameras FC.

[0073] The tracking unit 414 tracks each of the targets included in the image. The tracking unit 414 tracks each of the targets in the tracking area based on the image. Fig. 12 illustrates an example of an image I acquired from the face camera FC. Fig. 12 illustrates an example of a case where there are four targets in the tracking area. In this case, the tracking unit 414 may track each of targets TP0, TP1, TP2, and TP3.

[0074] The image used by the tracking unit 414 for tracking may be one frame of a video. In this case, the face image acquisition unit 3111 may sequentially acquire multiple frames constituting the video as images. The tracking unit 414 may perform tracking by associating the same object in a past frame with the current frame. For example, the tracking unit 414 may perform tracking by determining the position of the head region in the image. The tracking unit 414 may associate the same object in different frames based on the position of the head region in the image. The tracking unit 414 may perform tracking by determining the identity of the image pattern of the head region, for example. Furthermore, the tracking unit 414 may perform tracking by determining the similarity of feature information extracted from the image of the head region.

[0075] When multiple face cameras FC are provided, the tracking unit 414 may track each of the targets included in each of the multiple images captured by the multiple face cameras FC. For example, the tracking unit 414 may merge the targets included in each of the multiple images by extracting and matching characteristic parts of the targets. The characteristic parts of the targets may be, for example, the head region of the target, the upper body region of the target, or items worn by the target. The characteristic parts of the targets may be parts that can distinguish between individuals. The characteristic parts of the targets do not have to be parts that can identify an individual.

[0076] The tracking unit 414 may determine that the target is standing still when it detects at least one of an object that has been in the same position for a predetermined period of time or longer and that has the same size for a predetermined period of time or longer in the image. The information processing device 4 may have a mechanism for outputting information to the target that warns it that it is standing still, and may output the information to warn it that it is standing still. Furthermore, the face camera FC may be installed at a height that prevents the target from looking into the camera lens, thereby preventing the target from standing still.

[0077] The identification unit 415 identifies two objects (step S41). The identification unit 415 identifies two objects from the objects included in the image. The identification unit 415 identifies the two objects located in the foreground in the image from among the objects for which it has not been determined whether they will be captured by the first iris camera IC1 or the second iris camera IC2.

[0078] 12, it has been determined that target TP0 will be imaged by the first iris camera IC1, but it has not been determined whether targets TP1, TP2, and TP3 will be imaged by the first iris camera IC1 or the second iris camera IC2. In this case, the identification unit 415 identifies the two targets (target TP1 and target TP2) located in the foreground in image I. Note that if there are fewer than two targets for which it has not been determined whether they will be imaged by the first iris camera IC1 or the second iris camera IC2, the identification unit 415 may identify fewer than two targets.

[0079] The determination unit 3112 determines one of the two subjects as the first subject whose iris is to be imaged by the first iris camera IC1, and determines the other of the two subjects as the second subject whose iris is to be imaged by the second iris camera IC2 (step S32). In the example shown in Fig. 12, the determination unit 3112 determines, of subjects TP1 and TP2, subject TP1 located on the left side of image I as the first subject whose iris is to be imaged by the first iris camera IC1, and determines subject TP2 located on the right side of image I as the second subject whose iris is to be imaged by the second iris camera IC2.

[0080] The first iris camera IC1 captures an image of the iris of the first target TP1 to obtain an iris image 1 including the iris of the first target TP1. The second iris camera IC2 captures an image of the iris of the second target TP2 to obtain an iris image 2 including the iris of the second target TP2. The authentication unit 312 obtains the iris image 1 from the first iris camera IC1 and the iris image 2 from the second iris camera IC2 (step S33). The authentication unit 312 performs authentication using the iris image 1 and authentication using the iris image 2 (step S34). The authentication result notification unit 313 notifies the first target TP1 and the second target TP2 of the authentication result (step S35).

[0081] The tracking unit 414 may delete the first target TP1 from the tracking targets when the first iris camera IC1 acquires an iris image of the first target TP1. Also, the tracking unit 414 may delete the second target TP2 from the tracking targets when the second iris camera IC2 acquires an iris image of the second target TP2. Alternatively, the tracking unit 414 may delete the first target TP1 from the tracking targets when the authentication unit 312 successfully performs iris authentication of the first target TP1. Also, the tracking unit 414 may delete the second target TP2 from the tracking targets when the authentication unit 312 successfully performs iris authentication of the second target TP2. [4-3: Technical Effects of the Information Processing Device 4]

[0082] When an image contains three or more people, the information processing device 4 according to this disclosure identifies the next two people to be subjected to iris authentication, thereby enabling the iris cameras to be associated with the subjects one after another. [5: Fifth Embodiment]

[0084] 13 , the information processing system Sb includes an information processing device 5, a face camera FC, a first iris camera IC1, and a second iris camera IC2. The information processing device 5 may be the same as at least one of the information processing device 3 and the information processing device 4.

[0085] As shown in FIG. 13 , in the fifth embodiment, in a space in which a first target TP1 and a second target TP2 can move side by side, one side and the other side in the horizontal direction perpendicular to the movement direction are given different appearances. For example, the same color may be applied to the right side of the floor of lane L as seen from the target and the first iris camera IC1, and the same color may be applied to the left side of the floor of lane L as seen from the target and the second iris camera IC2. For example, blue may be applied to the right side of the floor of lane L as seen from the target and the first iris camera IC1, and green may be applied to the left side of the floor of lane L as seen from the target and the second iris camera IC2. For example, the same pattern may be applied to the right side of the floor of lane L as seen from the target and the first iris camera IC1, and the same pattern may be applied to the left side of the floor of lane L as seen from the target and the second iris camera IC2. [5-2: Technical Effects]

[0086] The information processing device 5 according to this disclosure can prompt the subject to look at an iris camera of the same color as the location where the subject is moving. The information processing device 5 can notify the subject of the iris camera capturing an image of the subject. Furthermore, the information processing device 5 can prevent the subject from moving from left to right and from right to left. [6: Sixth Embodiment]

Note that, for the sixth embodiment, descriptions that overlap with the descriptions of the first to fifth embodiments will be omitted as appropriate. Also, in the drawings, parts common to the second to fifth embodiments are indicated by the same reference numerals. [6-1: Configuration of Information Processing System Sc]

[0088] As shown in Fig. 14, the information processing system Sc includes an information processing device 6, a face camera FC, a first iris camera IC1, and a second iris camera IC2. The information processing device 6 may communicate with the face camera FC, the first iris camera IC1, and the second iris camera IC2 via a communication device 23. As shown in Fig. 14, the arithmetic device 21 included in the information processing device 6 may have, as logically realized functional blocks or as physically realized processing circuits, an imaging control unit 311, an authentication unit 312, an authentication result notification unit 313, a tracking unit 414, and an identification unit 415, as well as a determination result notification unit 616. [6-2: Information Processing Method Executed by Information Processing Device 6]

[0089] The information processing device 6 is configured as a device for sequentially acquiring iris images from an object moving in a movement direction and sequentially performing iris authentication. An information processing method executed by the information processing device 6 will be described with reference to Fig. 15 to Fig. 17. Fig. 15 is a flowchart showing the flow of the information processing method executed by the information processing device 6. Figs. 16 and 17 are schematic diagrams showing an overview of the information processing method executed by the information processing device 6.

[0090] 15 , the face image acquisition unit 3111 acquires an image from the face camera FC (step S31). The tracking unit 414 tracks each of the targets included in the image. The identification unit 415 identifies two targets (step S41). The determination unit 3112 determines one of the two targets as a first target whose iris is to be imaged by the first iris camera IC1, and determines the other of the two targets as a second target whose iris is to be imaged by the second iris camera IC2 (step S32).

[0091] The determination result notifying unit 616 notifies the first target that they will be imaged by the first iris camera IC1, and notifies the second target that they will be imaged by the second iris camera IC2 (step S61).

[0092] The determination result notification unit 616 may irradiate a first target with directional light from a position adjacent to the first iris camera IC1, and may irradiate a second target with directional light from a position adjacent to the second iris camera IC2. The determination result notification unit 616 may irradiate the first target with light from a position adjacent to the first iris camera IC1, and may irradiate the second target with light from a position adjacent to the second iris camera IC2, for example, using a laser pointer. As illustrated in FIG. 16 , the determination result notification unit 616 may irradiate a first target TP1 determined to be imaged by the first iris camera IC1 with light L1, and may irradiate a second target TP2 determined to be imaged by the second iris camera IC2 with light L2. [Notification Example 2]

[0093] The determination result notification unit 616 may display information indicating a first target adjacent to the first iris camera IC1 and information indicating a second target adjacent to the second iris camera IC2. As illustrated in FIG. 17 , a display D1 may be provided behind the first iris camera IC1, and a display D2 may be provided behind the second iris camera IC2. The determination result notification unit 616 may enlarge and display the face area of ​​the first target TP1 in the image acquired from the face camera FC on the display D1, and enlarge and display the face area of ​​the second target TP2 in the image acquired from the face camera FC on the display D2. For example, if the face of the target is close to the face of another person, the determination result notification unit 616 may perform an emphasis process, such as surrounding the target's face with a frame. Note that if the iris of the target moving in front has not been captured when the determination unit 3112 makes a determination, the determination result notification unit 616 may display the information indicating the target after the iris of the target moving in front has been captured.

[0094] The authentication unit 312 acquires iris image 1 of the first target TP1 from the first iris camera IC1 and acquires iris image 2 of the second target TP2 from the second iris camera IC2 (step S33). The authentication unit 312 performs authentication using iris image 1 and authentication using iris image 2 (step S34). The authentication result notification unit 313 notifies the first target TP1 and the second target TP2 of the authentication result (step S35).

[0095] In the sixth embodiment, as in the fifth embodiment, one side and the other side in the horizontal direction perpendicular to the direction of movement of the first target TP1 and the second target TP2 in the space in which they can move side by side may be made to look different. [6-3: Technical Effects of the Information Processing Device 6]

[0096] The information processing device 6 according to this disclosure can notify the subject whether they will be photographed by the iris camera. The information processing device 6 can make the subject face the iris camera. Also, for example, when there is only one subject and the subject is moving in the center of the lane L, the subject can easily understand which way to face. [7: Seventh Embodiment]

[0097] A seventh embodiment of an information processing device, an information processing system, an information processing method, and a program will be described with reference to FIGS. 18 to 21. Hereinafter, the seventh embodiment of an information processing device, an information processing system, an information processing method, and a program will be described using an information processing system S including an information processing device 7 according to this disclosure. Note that, for the seventh embodiment, descriptions that overlap with the descriptions of the first to sixth embodiments will be omitted as appropriate. Also, in the drawings, parts common to the second to sixth embodiments are indicated by the same reference numerals. [7-1: Configuration of information processing system Sd]

[0098] 18 , the information processing system Sd includes an information processing device 7, a face camera FC, a first iris camera IC1, and a second iris camera IC2.

As shown in FIG. 18 , the arithmetic device 21 included in the information processing device 7 may have, as logically realized functional blocks or as physically realized processing circuits, an imaging control unit 311, an authentication unit 312, an authentication result notifying unit 313, a tracking unit 414, an identification unit 415, and a determination result notifying unit 616, as well as a replacement information output unit 717. The replacement information output unit 717 outputs information about the replacement of the targets when the tracking unit 414 detects a replacement of the first target located on one side of the second target in the horizontal direction of the image with an target located on the other side of the second target in the horizontal direction of the image after the determination unit 3112 determines the first iris camera IC1 that captures the iris of the first target and the second iris camera IC2 that captures the iris of the second target. The replacement information output unit 717 may include an error output unit 7171, an attitude control unit 7172, and a determination update unit 7173. [7-2: First information processing method executed by information processing device 7]

[0099] The information processing device 7 is configured as a device for sequentially acquiring iris images from an object moving in a movement direction and sequentially performing iris authentication. A first information processing method executed by the information processing device 7 will be described with reference to Fig. 19. Fig. 19 is a flowchart showing the flow of the first information processing method executed by the information processing device 7.

[0100] 19 , the face image acquisition unit 3111 acquires an image from the face camera FC (step S31). The identification unit 415 identifies two subjects (step S41). The determination unit 3112 determines one of the two subjects as a first subject whose iris is to be imaged by the first iris camera IC1, and determines the other of the two subjects as a second subject whose iris is to be imaged by the second iris camera IC2 (step S32).

[0101] The tracking unit 414 tracks the target and detects a change in the target position (step S71). A change in the target position occurs when a first target located on one side of a second target in the horizontal direction of the image is moved to the other side of the second target in the horizontal direction of the image. Alternatively, a change in the target position occurs when a second target located on the other side of the first target in the horizontal direction of the image is moved to one side of the first target in the horizontal direction of the image. If a change in the target position is detected (step S71: Yes), the error output unit 7171 outputs an error (step S72). The error output unit 7171 may output information, for example, to prompt the target to move backward in the direction of movement and to walk again in lane L.

[0102] If no target change is detected (step S71: No), the authentication unit 312 acquires iris image 1 of the first target TP1 from the first iris camera IC1 and acquires iris image 2 of the first target TP1 from the second iris camera IC2 (step S33). The authentication unit 312 performs authentication using iris image 1 and authentication using iris image 2 (step S34). The authentication result notification unit 313 notifies the first target TP1 and the second target TP2 of the authentication result (step S35). [7-3: Second Information Processing Method Executed by Information Processing Device 7]

[0103] The second information processing method executed by the information processing device 7 will be described with reference to Fig. 20. Fig. 20 is a flowchart showing the flow of the second information processing method executed by the information processing device 7.

[0104] 20 , the face image acquisition unit 3111 acquires an image from the face camera FC (step S31). The identification unit 415 identifies two subjects (step S41). The determination unit 3112 determines one of the two subjects as a first subject whose iris is to be imaged by the first iris camera IC1, and determines the other of the two subjects as a second subject whose iris is to be imaged by the second iris camera IC2 (step S32).

[0105] The tracking unit 414 tracks the target and detects a change in the target's position (step S71). If a change in the target's position is detected (step S71: Yes), the attitude control unit 7172 changes the attitude of at least one of the first iris camera IC1 and the second iris camera IC2 (step S73). The attitude control unit 7172 may change the orientation of at least one of the iris camera housings and mirrors of the iris cameras of at least one of the first iris camera IC1 and the second iris camera IC2 to move the imaging range of the iris camera up, down, left, and right, thereby tracking the iris of the changed target. If tracking is not possible, the error output unit 7171 may output an error. If a change in the target's position is not detected (step S71: No), the process proceeds to step S33.

[0106] The authentication unit 312 acquires the iris image 1 of the first target TP1 from the first iris camera IC1 and acquires the iris image 2 of the first target TP1 from the second iris camera IC2 (step S33). The authentication unit 312 performs authentication using the iris image 1 and authentication using the iris image 2 (step S34). The authentication result notification unit 313 notifies the first target TP1 and the second target TP2 of the authentication result (step S35). [7-4: Third information processing method executed by the information processing device 7]

[0107] The third information processing method executed by the information processing device 7 will be described with reference to Fig. 21. Fig. 21 is a flowchart showing the flow of the third information processing method executed by the information processing device 7.

[0108] 21 , the face image acquisition unit 3111 acquires an image from the face camera FC (step S31). The identification unit 415 identifies two subjects (step S41). The determination unit 3112 determines one of the two subjects as a first subject whose iris is to be imaged by the first iris camera IC1, and determines the other of the two subjects as a second subject whose iris is to be imaged by the second iris camera IC2 (step S32).

[0109] The tracking unit 414 tracks the target and detects a change in the target (step S71). If a change in the target is detected (step S71: Yes), the determination update unit 7173 determines that the first iris camera IC1 will capture an image of the second target and the second iris camera IC2 will capture an image of the first target (step S74). In other words, if a change in the target is detected, the determination update unit 7173 updates the correspondence between the iris cameras and the target. If a change in the target is not detected (step S71: No), the process proceeds to step S33.

[0110] The authentication unit 312 acquires iris image 1 of the first target TP1 from the first iris camera IC1 and acquires iris image 2 of the first target TP1 from the second iris camera IC2 (step S33). The authentication unit 312 performs authentication using iris image 1 and authentication using iris image 2 (step S34). The authentication result notification unit 313 notifies the first target TP1 and the second target TP2 of the authentication result (step S35).

[0111] In the seventh embodiment, as in the fifth embodiment, one side of the space in which the first target TP1 and the second target TP2 can move side by side may have a different appearance from the other side in the horizontal direction perpendicular to the direction of movement. Also, in the seventh embodiment, as in the sixth embodiment, the first target may be notified that they will be imaged by the first iris camera IC1, and the second target may be notified that they will be imaged by the second iris camera IC2. [7-3: Technical Effects of the Information Processing Device 7]

[0112] The information processing device 7 according to this disclosure operates so as to be able to acquire an iris image even if the target is replaced after the iris camera and the target are associated with each other. [8: Eighth Embodiment]
