[0009] Hereinafter, embodiments of an information processing system, an information processing method, and a recording medium will be described with reference to the drawings.

[0010] First Embodiment An information processing system according to a first embodiment will be described with reference to FIGS. 1 to 3. FIG.

[0011] (Hardware Configuration) First, the hardware configuration of the information processing system according to the first embodiment will be described with reference to Fig. 1. Fig. 1 is a block diagram showing the hardware configuration of the information processing system according to the first embodiment.

[0012] 1 , an information processing system 10 according to the first embodiment includes a processor 11, a RAM (Random Access Memory) 12, a ROM (Read Only Memory) 13, and a storage device 14. The information processing system 10 may further include an input device 15, an output device 16, and a camera 18. The processor 11, RAM 12, ROM 13, storage device 14, input device 15, output device 16, and camera 18 are connected via a data bus 17.

[0013] The processor 11 loads a computer program. For example, the processor 11 is configured to load a computer program stored in at least one of the RAM 12, the ROM 13, and the storage device 14. Alternatively, the processor 11 may load a computer program stored in a computer-readable storage medium using a storage medium reading device (not shown). The processor 11 may acquire (i.e., load) the computer program from a device (not shown) located outside the information processing system 10 via a network interface. The processor 11 controls the RAM 12, the storage device 14, the input device 15, and the output device 16 by executing the loaded computer program. In particular, in this embodiment, when the processor 11 executes the loaded computer program, a functional block for outputting guide information when capturing an iris image is realized within the processor 11. That is, the processor 11 may function as a controller that executes each control in the information processing system 10.

[0014] The processor 11 may be configured as, for example, a central processing unit (CPU), a graphics processing unit (GPU), a field-programmable gate array (FPGA), a digital signal processor (DSP), an application-specific integrated circuit (ASIC), or a quantum processor. The processor 11 may be configured as one of these, or may be configured to use multiple processors in parallel.

[0015] The RAM 12 temporarily stores computer programs executed by the processor 11. The RAM 12 temporarily stores data that the processor 11 temporarily uses while it is executing the computer programs. The RAM 12 may be, for example, a dynamic random access memory (D-RAM) or a static random access memory (SRAM). Alternatively, other types of volatile memory may be used instead of the RAM 12.

[0016] The ROM 13 stores computer programs executed by the processor 11. The ROM 13 may also store fixed data. The ROM 13 may be, for example, a programmable read-only memory (PROM) or an erasable read-only memory (EPROM). Alternatively, other types of non-volatile memory may be used instead of the ROM 13.

[0017] The storage device 14 stores data that is to be saved long-term by the information processing system 10. The storage device 14 may operate as a temporary storage device for the processor 11. The storage device 14 may include, for example, at least one of a hard disk device, a magneto-optical disk device, an SSD (Solid State Drive), and a disk array device.

[0018] The input device 15 is a device that receives input instructions from a user of the information processing system 10. The input device 15 may include, for example, at least one of a keyboard, a mouse, and a touch panel. The input device 15 may be configured as a mobile terminal such as a smartphone or a tablet. The input device 15 may also be, for example, a device that includes a microphone and is capable of voice input.

[0019] The output device 16 is a device that outputs information related to the information processing system 10 to the outside. For example, the output device 16 may be a display device (e.g., a display) that can display information related to the information processing system 10. The output device 16 may also be a speaker or the like that can output information related to the information processing system 10 as audio. The output device 16 may be configured as a mobile terminal such as a smartphone or a tablet. The output device 16 may also be a device that outputs information in a format other than an image. For example, the output device 16 may be a speaker that outputs information related to the information processing system 10 as audio.

[0020] The camera 18 is configured to capture images or videos. The type of camera 18 is not particularly limited, and may be, for example, a visible light camera or a near-infrared camera. The camera 18 may be mounted on a terminal (e.g., a smartphone) owned by a user. The information processing system 10 may also be provided with multiple cameras 18. In this case, the multiple cameras may be of different types (e.g., cameras with different imaging ranges, imaging angles, imaging quality, etc.).

[0021] 1 illustrates an example of an information processing system 10 including multiple devices, but all or some of the functions may be realized by a single device (information processing device). In this case, the information processing device may be configured to include only the processor 11, RAM 12, and ROM 13 described above, and the other components (i.e., the storage device 14, input device 15, output device 16, and camera 18) may be provided by an external device connected to the information processing device. Furthermore, some of the calculation functions of the information processing device may be realized by an external device (e.g., an external server, a cloud, etc.).

[0022] (Functional Configuration) Next, the functional configuration of the information processing system 10 according to the first embodiment will be described with reference to Fig. 2. Fig. 2 is a block diagram showing the functional configuration of the information processing system according to the first embodiment.

[0023] As shown in Fig. 2, the information processing system 10 according to the first embodiment is configured to include, as components for realizing its functions, a photographing unit 110 and a guide information output unit 120. The photographing unit 110 may be configured to include, for example, the above-mentioned camera 18. The guide information output unit 120 may be a processing block realized by, for example, the above-mentioned processor 11 (see Fig. 1).

[0024] The image capturing unit 110 is configured to be able to capture an eye image including the iris of a target. Note that the "target" here is not limited to a human being, but may include, for example, animals such as dogs and cats, robots, etc. The image captured by the image capturing unit 110 may be, for example, an image used for iris authentication. Specifically, the image capturing unit 110 may capture a registration image for iris authentication (i.e., an image of the person registered in advance) or an image captured during iris authentication (i.e., an image used to authenticate whether the person is the person by comparing it with the registration image).

[0025] The guide information output unit 120 is configured to be able to output first guide information when capturing an eye image with the imaging unit 110. Furthermore, the information processing system 10 according to this embodiment is premised on the assumption that a photographer other than the subject of imaging will capture an iris image, and the guide information output unit 120 outputs first guide information to the photographer other than the subject of imaging. The guide information output unit 120 outputs the first guide information as information for capturing an image in which iris authentication is possible. Note that, here, an "image in which iris authentication is possible" refers to an image of sufficient quality to successfully perform iris authentication. For example, a quality standard that satisfies a predetermined authentication accuracy may be set by prior simulation, etc. Note that examples of images of sufficient quality include images with high resolution, images with a large iris region (e.g., an image of the eye wide open, an image in which the iris is captured close to the camera, etc.), and images in which the entire iris is captured.

[0026] The first guide information may include, for example, information for improving the quality of the eye image. Specifically, the first guide information may include information that prompts changing the position of the camera 18 or adjusting camera parameters, etc. The first guide information may include a plurality of pieces of information. In this case, the plurality of pieces of information may be output simultaneously or sequentially. The first guide information may be information that is output via the output device 16 described above, for example. More specifically, the first guide information may be displayed on a display or may be output as audio from a speaker. Alternatively, the first guide information may be information that is output using a vibration function. More specific examples of the first guide information will be described in detail in other embodiments described later.

[0027] (Operation Flow) Next, the operation flow of the information processing system 10 according to the first embodiment will be described with reference to Fig. 3. Fig. 3 is a flowchart showing the operation flow of the information processing system according to the first embodiment.

[0028] 3, when the operation of the information processing system 10 according to the first embodiment is started, the image capturing unit 110 first starts capturing eye images (step S101). Note that the start of capturing does not refer to the timing at which each eye image is captured by an operation by the photographer (e.g., pressing the shutter button, etc.), but may refer to the timing at which the photographer holds the camera 18 toward the subject and the image capturing range of the camera 18 starts to be displayed as a live view image.

[0029] Next, the guide information output unit 120 outputs first guide information to the photographer (step S102). The first guide information may be generated and output based on an image captured by the imaging unit 110, for example. That is, the first guide information may be information that changes depending on the current imaging environment, etc. Note that, although an example has been given here in which the first guide information is output after imaging of an eye image begins, the first guide information may also be output before imaging of an eye image begins.

[0030] (Technical Effects) Next, technical effects obtained by the information processing system 10 according to the first embodiment will be described.

[0031] 1 to 3, in the information processing system 10 according to the first embodiment, first guide information is output to the photographer when capturing an eye image. In this way, even a photographer who is not accustomed to capturing iris images can refer to the first guide information and capture an eye image suitable for iris authentication.

[0032] Second Embodiment An information processing system 10 according to a second embodiment will be described with reference to Figures 4 and 5. Note that the second embodiment differs from the first embodiment described above only in some configurations, and other parts may be the same as the first embodiment. Therefore, the following will describe in detail the parts that differ from the first embodiment already described, and will omit descriptions of other overlapping parts as appropriate.

[0033] (Functional Configuration) First, the functional configuration of the information processing system 10 according to the second embodiment will be described with reference to Fig. 4. Fig. 4 is a block diagram showing the functional configuration of the information processing system according to the second embodiment. Note that in Fig. 4, elements similar to those shown in Fig. 2 are denoted by the same reference numerals.

[0034] As shown in Fig. 4, the information processing system 10 according to the second embodiment is configured to include, as components for realizing its functions, an imaging unit 110, a guide information output unit 120, and a display unit 130. That is, the information processing system 10 according to the second embodiment further includes a display unit 130 in addition to the configuration of the first embodiment (see Fig. 2). The display unit 130 may be configured as the above-mentioned output device 16 (see Fig. 1), for example. The display unit 130 according to this embodiment is particularly configured to be able to display first guide information. For example, the display unit 130 may be configured to be able to display messages, icons, marks, etc. indicated by the first guide information.

[0035] (Layout Configuration) Next, the layout configuration of the above-mentioned image capturing unit 110 and display unit 130 will be described with reference to Fig. 5. Fig. 5 is a side view showing an example of the layout of the image capturing unit and the display unit in an information processing system according to the second embodiment.

[0036] 5 , the imaging unit 110 and the display unit 130 according to the second embodiment may be mounted on the same smartphone 50. For example, the imaging unit 110 may be a main camera mounted on the smartphone 50. The display unit 130 may be a main display mounted on the smartphone 50.

[0037] In particular, in the information processing system according to the second embodiment, the imaging unit 110 is disposed on the rear side of the display unit 130. That is, the imaging direction of the imaging unit 110 and the display direction of the display unit 130 are disposed in opposite directions. Note that, although an example is given here in which the imaging direction of the imaging unit 110 and the display direction of the display unit 130 are 180 degrees opposite each other, these directions do not necessarily need to be 180 degrees apart. That is, the "rear side" in this embodiment does not mean that the imaging direction is strictly 180 degrees opposite, but rather allows for some margin, and even in such a case, the technical effects described below can be obtained accordingly.

[0038] (Technical Effects) Next, technical effects obtained by the information processing system 10 according to the second embodiment will be described.

[0039] As described with reference to FIGS. 4 and 5 , in the information processing system 10 according to the second embodiment, the imaging unit 110 that captures an image of the subject is disposed on the rear side of the display unit 130 that displays the first guide information. In this manner, the first guide information can be appropriately output to the photographer who holds the imaging unit 110 toward the subject. Furthermore, in terminals such as the smartphone 50 described above, in addition to a rear camera (a so-called outer camera) such as the imaging unit 110, a camera (a so-called inner camera) may also be provided on the display unit 130 side, but the image quality of this inner camera is often lower than that of the outer camera. However, in this embodiment, even when using such a terminal, the first guide information can be output to the photographer with the outer camera capable of capturing high-quality images pointed toward the subject.

[0040] Third Embodiment An information processing system 10 according to a third embodiment will be described with reference to Figures 6 and 7. Note that the third embodiment describes a specific example of first guide information, and the system configuration and overall operational flow may be the same as those of the first and second embodiments. Therefore, the following will describe in detail the parts that differ from the embodiments already described, and will omit explanations of other overlapping parts as appropriate.

[0041] (Iris image capture frame) First, an iris image capture frame displayed in the information processing system 10 according to the third embodiment will be described with reference to Fig. 6. Fig. 6 is a plan view showing a display example of the iris image capture frame in the information processing system according to the third embodiment.

[0042] As shown in FIG. 6 , in the information processing system 10 according to the third embodiment, an iris image capture frame may be displayed on the display unit 130 by the first guide information. The iris image capture frame is displayed as a guide for capturing an eye image that can be iris authenticated. The iris image capture frame is set so that an eye image that can be iris authenticated can be captured by capturing an image of the iris 200 so that the iris 200 fits within the frame. More specifically, the position at which the iris image capture frame is displayed may correspond to an appropriate position of the iris 200 in the image. Furthermore, the size of the iris image capture frame may correspond to an appropriate size of the iris 200 in the image. The first guide information may include information regarding the position and size of the iris image capture frame in order to display the iris image capture frame.

[0043] The iris image frame is displayed superimposed on the captured image. Note that the captured image here may be a live view image displayed in real time. By displaying the iris image frame superimposed on the captured image in this manner, the photographer can easily understand how to move the imaging unit 110 (i.e., the camera 18) so that the iris 200 fits within the iris image capture frame. For example, as shown in FIG. 6 , if the iris 200 of the subject is captured shifted to the right from the iris image capture frame, the photographer can fit the iris 200 of the subject within the iris image capture frame by moving the camera 18 to the right.

[0044] (Pupil Frame) Next, a pupil frame displayed in the information processing system 10 according to the third embodiment will be described with reference to Fig. 7. Fig. 7 is a plan view showing a display example of an iris imaging frame and a pupil frame in the information processing system according to the third embodiment.

[0045] 7 , in the information processing system 10 according to the third embodiment, a pupil frame may be displayed in addition to the iris image capture frame described above. In this case, the first guide information may include information for displaying the pupil frame in addition to information for displaying the iris image frame.

[0046] The pupil frame is set so that an eye image capable of iris authentication can be captured by fitting the pupil 300 within the frame. More specifically, the position at which the pupil frame is displayed may be set to achieve an appropriate position of the iris 200 in the image. For example, the position of the pupil frame may be set so that fitting the pupil 300 within the frame will result in the iris 200 located around it being in an appropriate position. Furthermore, the size of the pupil frame may be set so that an appropriate state of the iris 200 can be achieved in the image. For example, the size of the pupil frame may be set so that fitting the pupil 300 within the frame will result in the iris 200 located around it being clearly visible (e.g., a state in which contraction of the iris 200 due to dilation of the pupil 300 is suppressed).

[0047] If the pupil 300 has expanded to a size that does not fit within the pupil frame, control may be performed, for example, by increasing the intensity of illumination to constrict the pupil 300. For example, when an image is captured using the smartphone 50 shown in FIG. 5 , the information processing system 10 may increase the light intensity of a light mounted on the smartphone 50 to constrict the pupil.

[0048] (Technical Effects) Next, technical effects obtained by the information processing system 10 according to the third embodiment will be described.

[0049] 6 and 7 , in the information processing system 10 according to the third embodiment, an iris image capture frame is displayed by the first guide information. Displaying the iris image capture frame makes it possible to capture an eye image including an iris of an appropriate size at an appropriate position. Furthermore, displaying a pupil frame in addition to the iris image capture frame makes it possible to adjust the position and size of the iris with higher precision.

[0050] Fourth Embodiment An information processing system 10 according to a fourth embodiment will be described with reference to Fig. 8. The fourth embodiment describes an example of the operation when displaying the iris image capture frame described in the third embodiment, and other parts may be the same as those of the third embodiment. Therefore, the following will describe in detail parts that differ from the embodiments already described, and will omit descriptions of other overlapping parts as appropriate.

[0051] (Frame display operation) First, a frame display operation (i.e., an operation when displaying an iris image capture frame) in the information processing system 10 according to the fourth embodiment will be described with reference to Fig. 8. Fig. 8 is a plan view showing an example of an operation when displaying an iris image capture frame in the information processing system according to the fourth embodiment.

[0052] As shown in Fig. 8, assume that the imaging unit 110 has captured an image including the entire face of the subject. At this stage, the iris image frame is not displayed. Here, when the photographer taps near the eye of the subject (i.e., the portion of the display unit 130 where the eye of the subject is displayed), the iris image frame is displayed, and the imaging unit 110 zooms in on the tapped area (i.e., the area around the eye of the subject). This makes it easy to fit the iris 200 of the subject within the iris image frame.

[0053] (Technical Effects) Next, technical effects obtained by the information processing system 10 according to the fourth embodiment will be described.

[0054] 8, in the information processing system 10 according to the fourth embodiment, an iris image capturing frame is displayed and the area around the eye is zoomed in in response to an operation around the eye of the subject to be captured. In this way, it is possible to switch to a state in which an appropriate iris image can be captured with a simple operation.

[0055] Fifth Embodiment An information processing system 10 according to a fifth embodiment will be described with reference to Fig. 9. The fifth embodiment describes a specific example of first guide information, and other parts may be the same as the first to fourth embodiments. Therefore, the following will describe in detail parts that differ from the embodiments already described, and will omit explanations of other overlapping parts as appropriate.

[0056] (Travel direction display) First, the first guide information displayed by the information processing system 10 according to the fifth embodiment will be specifically described with reference to Fig. 9. Fig. 9 is a plan view showing an example of the display of the first guide information in the information processing system according to the fifth embodiment.

[0057] 9 , in the information processing system 10 according to the fifth embodiment, the first guide information is output as information indicating the movement direction of the photographing unit 110 (i.e., the camera 18). More specifically, the first guide information includes information indicating in which direction the imaging range of the photographing unit 110 should be moved in order to fit the iris 200 of the photographing target within the iris imaging frame.

[0058] For example, as shown in FIG. 9 , when the iris 200 of the subject is photographed shifted to the right from the iris imaging frame, a message saying "Move the camera to the right" and a right-pointing arrow may be displayed based on the first guide information. The first guide information may also include information for outputting the above-described message as audio. Furthermore, when a device with a vibration function, such as the smartphone 50, is used, the first guide information may indicate the direction in which to move the camera 18 by vibrating. For example, when the camera 18 is moved to the right, the right side of the smartphone 50 may vibrate, and when the camera is moved to the left, the left side of the smartphone 50 may vibrate. Alternatively, when the camera 18 is moved to the right, the smartphone 50 may vibrate only once, and when the camera is moved to the left, the smartphone 50 may vibrate twice in succession.

[0059] (Technical Effects) Next, technical effects obtained by the information processing system 10 according to the fifth embodiment will be described.

[0060] 9 , in the information processing system 10 according to the fifth embodiment, the first guide information is displayed as information indicating in which direction to move the imaging range of the imaging unit 110. In this way, the photographer can adjust the direction of the imaging unit 110 in accordance with the guide, thereby enabling the photographer to appropriately capture an image of the iris.

[0061] Sixth Embodiment An information processing system 10 according to a sixth embodiment will be described with reference to Figures 10 and 11. Note that the sixth embodiment differs only in part of the configuration and operation from the first to fifth embodiments described above, and other parts may be the same as the first to fifth embodiments. Therefore, the following will describe in detail the parts that differ from the embodiments already described, and will omit a description of other overlapping parts as appropriate.

[0062] (Functional Configuration) First, the functional configuration of the information processing system 10 according to the sixth embodiment will be described with reference to Fig. 10. Fig. 10 is a block diagram showing the functional configuration of the information processing system according to the sixth embodiment. Note that in Fig. 10, elements similar to those shown in Fig. 2 are denoted by the same reference numerals.

[0063] 10, the information processing system 10 according to the sixth embodiment is configured to include, as components for realizing its functions, an image capturing unit 110, a guide information output unit 120, and a determination unit 140. That is, the information processing system 10 according to the sixth embodiment further includes a determination unit 140 in addition to the configuration of the first embodiment (see FIG. 2). The determination unit 140 may be a processing block realized by, for example, the above-described processor 11 (see FIG. 1).

[0064] The determination unit 140 is configured to be able to determine whether or not an eye image satisfies an authenticatable condition by analyzing the eye image. Note that the "authenticatable condition" is a condition set for determining whether or not an eye image is iris-authenticable. The determination unit 140 may determine that an eye image that satisfies the authenticatable condition is an image that is iris-authenticable, and may determine that an eye image that does not satisfy the authenticatable condition is an image that is iris-authenticable.

[0065] The authenticatable conditions may include multiple conditions. In this case, it may be determined that the authenticatable conditions are met when all of the multiple conditions are met, or when a predetermined number or more of the multiple conditions are met. The authenticatable conditions may include, for example, conditions related to the position, size, and degree of opening of the iris. The authenticatable conditions may also include conditions related to the shooting environment (e.g., conditions related to brightness and lighting reflection). Furthermore, the authenticatable conditions may also include conditions related to camera parameters (e.g., resolution, sharpness, focus, exposure, shutter speed, etc.).

[0066] (Operation Flow) Next, the operation flow of the information processing system 10 according to the sixth embodiment will be described with reference to Fig. 11. Fig. 11 is a flowchart showing the operation flow of the information processing system according to the sixth embodiment. Note that in Fig. 11, the same processes as those shown in Fig. 3 are denoted by the same reference numerals.

[0067] 11, when the operation of the information processing system 10 according to the sixth embodiment is started, the photographing unit 110 first starts photographing an eye image (step S101), and the determination unit 140 then analyzes the photographed eye image (step S601).

[0068] Next, the determination unit 140 determines whether the eye image satisfies the authentication condition based on the analysis result of the eye image (step S602). If it is determined that the eye image does not satisfy the authentication condition (step S602: NO), the guide information output unit 120 outputs the first guide information (step S102).

[0069] On the other hand, if it is determined that the eye image satisfies the authentication condition (step S602: YES), the process of step S102 described above is skipped. That is, the guide information output unit 120 does not output the first guide information.

[0070] (Technical Effects) Next, technical effects obtained by the information processing system 10 according to the sixth embodiment will be described.

[0071] 10 and 11 , the information processing system 10 according to the sixth embodiment determines whether an eye image satisfies the authentication conditions, and outputs first guide information if the authentication conditions are not met. In this way, appropriate first guide information can be output according to the determination result of the eye image. Furthermore, since the first guide information is not output if the authentication conditions are met, it is possible to prevent the first guide information from being output even if an eye image of sufficient quality has been captured.

[0072] Seventh Embodiment An information processing system 10 according to a seventh embodiment will be described with reference to Fig. 12. Note that the seventh embodiment differs from the sixth embodiment described above only in some of its operations, and other parts may be the same as the first to sixth embodiments. Therefore, the following will describe in detail the parts that differ from the embodiments already described, and will omit a description of other overlapping parts as appropriate.

[0073] (Operation Flow) First, the operation flow of the information processing system 10 according to the seventh embodiment will be described with reference to Fig. 12. Fig. 12 is a flowchart showing the operation flow of the information processing system according to the seventh embodiment. Note that in Fig. 12, the same processes as those shown in Fig. 11 are denoted by the same reference numerals.

[0074] 12, when the operation of the information processing system 10 according to the seventh embodiment is started, the photographing unit 110 first starts photographing an eye image (step S101), and the determination unit 140 then analyzes the photographed eye image (step S601).

[0075] Next, the determination unit 140 determines whether or not the authentication condition is satisfied for each of a plurality of parameters based on the analysis result of the eye image (step S701). For example, if the authentication condition is set for each of focus, brightness, resolution, and size, the determination unit 140 determines whether or not the authentication condition is satisfied for each of focus, brightness, resolution, and size separately.

[0076] Thereafter, the guide information output unit 120 outputs first guide information based on the determination result for each parameter by the determination unit 140. Specifically, the guide information output unit 120 outputs first guide information for parameters for which it has been determined that the authenticatable conditions are not satisfied (step S702). For example, if the authenticatable conditions for focus and brightness are satisfied but the authenticatable conditions for resolution and size are not satisfied, the guide information output unit 120 outputs first guide information for resolution and size. Note that if the authenticatable conditions for all parameters are not satisfied, the first guide information output unit 120 may output first guide information for all parameters. Also, if the authenticatable conditions for all parameters are satisfied, the first guide information output unit 120 may not output the first guide information.

[0077] (Technical Effects) Next, technical effects obtained by the information processing system 10 according to the seventh embodiment will be described.

[0078] 12, in the information processing system 10 according to the seventh embodiment, the authentication conditions are determined for each of a plurality of parameters, and first guide information is output based on the determination results. In this way, it is possible to output more appropriate first guide information according to each of a plurality of parameters.

[0079] Eighth Embodiment An information processing system 10 according to an eighth embodiment will be described with reference to Figures 13 and 14. Note that the eighth embodiment differs from the seventh embodiment described above only in some of its operations, and other parts may be the same as the first to seventh embodiments. Therefore, the following will describe in detail the parts that differ from the embodiments already described, and will omit a description of other overlapping parts as appropriate.

[0080] (Parameter Display) First, a display example of first guide information by the information processing system 10 according to the eighth embodiment will be described with reference to Fig. 13. Fig. 13 is a plan view showing an output example of first guide information in the information processing system according to the eighth embodiment.

[0081] As shown in FIG. 13 , the information processing system 10 according to the eighth embodiment may display the determination results of the determination unit 140 for each of a plurality of parameters in a graph format on the display unit 130. The determination unit 140 may determine whether the authentication conditions are met based on whether each of the plurality of parameters exceeds a preset threshold (dotted line in the graph). In the example shown in FIG. 13 , the parameters related to focus and brightness have not reached their thresholds in the initial stage. Therefore, the determination unit 140 determines that the authentication conditions related to focus and brightness are not met. On the other hand, the parameters related to resolution and size exceed their thresholds. Therefore, the determination unit 140 determines that the authentication conditions related to resolution and size are met.

[0082] The determination unit 140 is further configured to determine the degree of deviation from the threshold (in other words, the degree of non-achievement) for parameters that have not reached the threshold. The guide information output unit 120 according to this embodiment is configured to output the first guide information in descending order of the deviation from the threshold. As already described, neither the focus-related nor brightness-related parameters have reached their thresholds in the initial stage, but the brightness-related parameter has a greater deviation from the threshold. In this case, the guide information output unit 120 first outputs the first guide information related to brightness. For example, the guide information output unit 120 outputs the first guide information for outputting a message such as "Please make it brighter" or "Please make it darker" (i.e., guide information for improving the brightness). Then, after the brightness-related parameter is improved, the guide information output unit 120 outputs the first guide information related to focus. For example, the guide information output unit 120 outputs the first guide information for outputting a message such as "Please move the focus further away" or "Please move the focus closer" (i.e., guide information for improving the focus).

[0083] (Modification) Next, a modification of the first guide information displayed by the information processing system 10 according to the eighth embodiment will be described with reference to Fig. 14. Fig. 14 is a plan view showing a modification of the first guide information in the information processing system according to the eighth embodiment.

[0084] As shown in Fig. 14 , the information processing system 10 according to the eighth embodiment may display the determination results for a plurality of parameters as a single bar with each parameter connected vertically. Parameters that have been improved by outputting the first guide information may be displayed with the corresponding portion being longer. In the example shown in Fig. 14 , the portion corresponding to brightness is longer because the parameter related to brightness has been improved. While an example has been given in which the overall length of the bar changes with changes in each parameter, the overall length of the bar may be fixed and the proportion of the portion corresponding to each parameter may be changed.

[0085] (Technical Effects) Next, technical effects obtained by the information processing system 10 according to the eighth embodiment will be described.

[0086] 13 and 14, in the information processing system 10 according to the eighth embodiment, the authentication possible conditions are determined based on thresholds set for each of a plurality of parameters, and first guide information corresponding to each parameter is output in an order according to the degree of deviation from the threshold. In this way, it is possible to output first guide information corresponding to a plurality of parameters in an appropriate order. This enables the photographer to adjust the parameters in order of priority.

[0087] Ninth Embodiment An information processing system 10 according to a ninth embodiment will be described with reference to Figures 15 and 16. Note that the ninth embodiment differs only in part of the configuration and operation from the first to eighth embodiments described above, and other parts may be the same as the first to eighth embodiments. Therefore, hereinafter, only the parts that differ from the embodiments already described will be described in detail, and descriptions of other overlapping parts will be omitted as appropriate.

[0088] (Functional Configuration) First, the functional configuration of the information processing system 10 according to the ninth embodiment will be described with reference to Fig. 15. Fig. 15 is a block diagram showing the functional configuration of the information processing system according to the ninth embodiment. Note that in Fig. 15, elements similar to those shown in Fig. 10 are denoted by the same reference numerals.

[0089] 15, the information processing system 10 according to the ninth embodiment is configured to include, as components for realizing its functions, an imaging unit 110, a guide information output unit 120, and a determination unit 140. In particular, the guide information output unit 120 according to the ninth embodiment is configured to be able to output second guide information for the subject to be photographed, in addition to first guide information for the photographer.

[0090] The selection unit 121 is configured to be able to select at least one of first guide information and second guide information as the guide information to be output by the guide information output unit 120. The selection unit 121 selects which guide information to output based on the determination result for each of the multiple parameters by the determination unit 140. For example, if an authentication condition related to a parameter that requires a response from the photographer (e.g., a camera parameter) is not met, the selection unit 121 may select the first guide information for the photographer. Furthermore, if an authentication condition related to a parameter that requires a response from the subject (e.g., the degree of eye opening) is not met, the selection unit 121 may select the second guide information for the subject. Furthermore, if an authentication condition related to a parameter that can be responded to by both the photographer and the subject (e.g., the position of the iris) is not met, the selection unit 121 may select both the first guide information for the photographer and the second guide information for the subject.

[0091] (Operation Flow) Next, the operation flow of the information processing system 10 according to the ninth embodiment will be described with reference to Fig. 16. Fig. 16 is a flowchart showing the operation flow of the information processing system according to the ninth embodiment. Note that in Fig. 16, the same processes as those shown in Fig. 11 are denoted by the same reference numerals.

[0092] 16, when the operation of the information processing system 10 according to the ninth embodiment is started, the photographing unit 110 first starts photographing an eye image (step S101), and the determination unit 140 then analyzes the photographed eye image (step S601).

[0093] Next, the determination unit 140 determines whether the eye image satisfies the authentication condition based on the analysis result of the eye image (step S602). If it is determined that the eye image satisfies the authentication condition (step S602: YES), the subsequent processes are omitted. That is, the guide information output unit 120 does not output the first guide information.

[0094] On the other hand, if it is determined that the eye image does not satisfy the authentication condition (step S602: NO), the selection unit 121 selects guide information to be output according to the parameter that does not satisfy the authentication condition (step S901). That is, it determines whether to output first guide information for the photographer, second guide information for the subject, or both the first guide information and the second guide information.

[0095] Thereafter, the guide information output unit 120 outputs the guide information selected by the selection unit 121 (step S902).

[0096] (Technical Effects) Next, technical effects obtained by the information processing system 10 according to the ninth embodiment will be described.

[0097] 15 and 16, in the information processing system 10 according to the ninth embodiment, first guide information for the photographer and second guide information for the subject to be photographed are selected and output as appropriate. In this way, it becomes possible to output appropriate guide information to an appropriate output destination depending on the situation when photographing.

[0098] Tenth Embodiment An information processing system 10 according to a tenth embodiment will be described with reference to Fig. 17. Note that the tenth embodiment differs from the ninth embodiment described above only in some of its operations, and other parts may be the same as the first to ninth embodiments. Therefore, the following will describe in detail the parts that differ from the embodiments already described, and will omit a description of other overlapping parts as appropriate.

[0099] (Output mode of guide information) First, the output mode of the first guide information and the second guide information in the information processing system 10 according to the tenth embodiment will be described with reference to Fig. 17. Fig. 17 is a conceptual diagram showing an example of output of the first guide information and the second guide information by the information processing system according to the tenth embodiment.

[0100] As shown in Fig. 17 , the information processing system 10 according to the tenth embodiment is configured to be able to output first guide information for the photographer and second guide information for the subject to be photographed in different modes. For example, the guide information output unit 120 displays first guide information for the photographer on the display unit 130, while the guide information output unit 120 outputs second guide information for the subject to be photographed as audio via a speaker. In the example shown in Fig. 17 , a message saying "Please move the camera to the right" is displayed to the photographer. Meanwhile, a message saying "Please move slightly to the right" is output as audio to the subject to be photographed.

[0101] 17 shows a configuration in which the first guide information is displayed as an image and the second guide information is output as audio, but this combination is merely an example, and the combination of output modes is not particularly limited. For example, the first guide information may be output using a vibration function, and the second guide information may be output as audio.

[0102] (Technical Effects) Next, technical effects obtained by the information processing system 10 according to the tenth embodiment will be described.

[0103] As described with reference to FIG. 17 , in the information processing system 10 according to the tenth embodiment, the first guide information and the second guide information are output in different modes. In this way, the first guide information for the photographer and the second guide information for the subject can be output in appropriate modes. In the example shown in FIG. 17 , guide information instructing both the photographer and the subject to move (move) to the right is output. However, if these were output in the same mode, the intent of the guide information may not be properly conveyed. For example, if a voice message saying "Please move to the right" is output to both the photographer and the subject, the photographer and the subject will be confused as to whether the direction is to the right from their perspective, or to the right from the other person's perspective (i.e., to the left from their perspective). However, in this embodiment, guide information is output in different modes for the photographer and the subject, which can avoid situations where such confusion occurs.

[0104] 11th Embodiment An information processing system 10 according to an 11th embodiment will be described with reference to Fig. 18 to Fig. 20. Note that the 11th embodiment differs from the 9th and 10th embodiments only in some of its operations, and other parts may be the same as the first to 10th embodiments. Therefore, the following will describe in detail the parts that differ from the embodiments already described, and will omit a description of other overlapping parts as appropriate.

[0105] (Functional Configuration) First, the functional configuration of the information processing system 10 according to the 11th embodiment will be described with reference to Fig. 18. Fig. 18 is a block diagram showing the functional configuration of the information processing system according to the 11th embodiment. Note that in Fig. 18, the same elements as those shown in Fig. 15 are denoted by the same reference numerals.

[0106] 18, the information processing system 10 according to the 11th embodiment is configured to include, as components for realizing its functions, an imaging unit 110, a guide information output unit 120, and a determination unit 140. In particular, the guide information output unit 120 according to the 11th embodiment includes a selection unit 121 and an adjustment determination unit 122. That is, the information processing system 10 according to the 9th embodiment further includes an adjustment determination unit 122 in addition to the configuration of the 9th embodiment (see FIG. 15).

[0107] The adjustment determination unit 122 is configured to be able to determine whether or not the first guide information output by the guide information output unit 120 (or guide information that has already been output) includes information that requires the photographer to adjust. For example, if the first guide information is information related to camera parameters, the photographer is requested to adjust the camera parameters. In this case, the adjustment determination unit 122 may determine that the first guide information includes information that requires adjustment.

[0108] The guide information output unit 120 according to this embodiment is configured to be able to output second guide information toward the subject to be photographed, based on the determination result by the adjustment determination unit 122. Specifically, when the adjustment determination unit 122 determines that adjustment by the photographer is required, the guide information output unit 120 outputs second guide information toward the subject to be photographed that instructs the subject to maintain a certain posture. The second guide information is output to prevent the image of the iris from being blurred due to movement of the subject to be photographed.

[0109] As can be seen from the above example, the "adjustment" determined in this embodiment takes a relatively short time. Therefore, if the adjustment takes a long time, the second guide information described in this embodiment (i.e., guide information for maintaining the photographer's posture) does not need to be output. How to deal with cases where the adjustment takes a long time will be described in the twelfth embodiment, which will be described later.

[0110] (Adjustment Determination Operation) Next, the flow of the adjustment determination operation (i.e., the operation of the adjustment determination unit 122) in the information processing system 10 according to the eleventh embodiment will be described with reference to Fig. 19. Fig. 19 is a flowchart showing the flow of the adjustment determination operation by the information processing system according to the eleventh embodiment.

[0111] 19 , the adjustment determination unit 122 in the information processing system 10 according to the eleventh embodiment first determines whether or not first guide information has been output to the photographer (step S1101). Note that if the first guide information has not been output (step S1101: NO), the subsequent processes may be omitted.

[0112] If first guide information has been output (step S1101: YES), the adjustment determination unit 122 determines whether or not the output first guide information requests the photographer to make an adjustment (step S1102). Note that if the first guide information does not request the photographer to make an adjustment (step S1102: NO), the subsequent processing may be omitted.

[0113] If the first guide information requests the photographer to make an adjustment (step S1102: YES), the guide information output unit 120 outputs second guide information instructing the subject to maintain the posture (step S1103). Note that the guide information output unit 120 may output information indicating that the posture maintenance may be released after the shooting is completed.

[0114] (Output example of guide information) Next, an output example of guide information by the information processing system 10 according to the eleventh embodiment will be described with reference to Fig. 20. Fig. 20 is a conceptual diagram showing an output example of first guide information and second guide information by the information processing system according to the eleventh embodiment.

[0115] 20 , it is assumed that the first guide information displays a message saying, "Move the camera to the right." In this case, the photographer is requested to move the camera 18 to the right to position the iris 200 of the subject to be photographed appropriately (i.e., to fit the iris 200 within the iris image capturing frame). Then, it is assumed that the photographer will photograph the eye image of the subject to be photographed after completing the adjustment of the camera 18.

[0116] In such a case, the adjustment determination unit 122 determines that the first guide information requires adjustment by the photographer. Then, the guide information output unit 120 outputs an audio message to the subject saying, "Please do not move for a while." This maintains the posture of the subject, and the photographer who has completed the adjustment can take an image with reduced blur.

[0117] It should be noted that the second guide information may include information other than information for maintaining posture. For example, the second guide information may include the content of the first guide information in order to inform the subject of photography of what adjustments the photographer is making. More specifically, the second guide information may output a message to the subject of photography saying, "The photographer is currently adjusting the camera position. Please do not move for a while."

[0118] (Technical Effects) Next, technical effects obtained by the information processing system 10 according to the eleventh embodiment will be described.

[0119] 18 to 20 , in the information processing system 10 according to the eleventh embodiment, when first guide information requiring adjustment by the photographer is output, second guide information instructing the subject to maintain its posture is output. In this way, an instruction is issued to the subject to not move, and the photographer who has completed adjustment based on the first guide information can appropriately photograph the iris of the subject.

[0120] <Twelfth Embodiment> An information processing system 10 according to a twelfth embodiment will be described with reference to Figures 21 and 22. Note that the twelfth embodiment differs from the eleventh embodiment described above only in some of its operations, and other parts may be the same as the first to eleventh embodiments. Therefore, the following will describe in detail the parts that differ from the embodiments already described, and will omit a description of other overlapping parts as appropriate.

[0121] (Adjustment Judgment Operation) First, the flow of the adjustment judgment operation in the information processing system 10 according to the twelfth embodiment will be described with reference to Fig. 21. Fig. 21 is a flowchart showing the flow of the adjustment judgment operation by the information processing system according to the twelfth embodiment. Note that in Fig. 21, the same processes as those shown in Fig. 19 are denoted by the same reference numerals.

[0122] 21 , the adjustment determination unit 122 in the information processing system 10 according to the twelfth embodiment first determines whether or not first guide information has been output to the photographer (step S1101). Note that if the first guide information has not been output (step S1101: NO), the subsequent processes may be omitted.

[0123] If first guide information has been output (step S1101: YES), the adjustment determination unit 122 determines whether or not the output first guide information requests the photographer to make an adjustment (step S1102). Note that if the first guide information does not request the photographer to make an adjustment (step S1102: NO), the subsequent processing may be omitted.

[0124] If the first guide information requests the photographer to make an adjustment (step S1102: YES), the adjustment determination unit 122 determines whether the adjustment requested of the photographer will take a predetermined time or more (step S1201). The "predetermined time" here is a threshold value for determining whether the adjustment will take a relatively long time. The predetermined time may be set based on, for example, the time the subject can maintain the posture without feeling any strain.

[0125] If it is determined that the adjustment will take more than a predetermined time (step S1201: YES), the guide information output unit 120 outputs second guide information to the subject to be photographed, informing that it will take some time before photographing begins (step S1202). On the other hand, if it is determined that the adjustment will not take more than the predetermined time (step S1201: NO), the guide information output unit 120 may output second guide information to the subject to be photographed, instructing the subject to maintain its posture (step S1103). In other words, the same second guide information as that described in the eleventh embodiment may be output.

[0126] (Output example of guide information) Next, an output example of guide information by the information processing system 10 according to the twelfth embodiment will be described with reference to Fig. 22. Fig. 22 is a conceptual diagram showing an output example of first guide information and second guide information by the information processing system according to the twelfth embodiment.

[0127] As shown in FIG. 22 , the first guide information may include guide information related to multiple parameters. For example, guide information for improving focus may be guide information that outputs a message such as "Please focus closer" or "Please focus further away." Guide information for improving brightness may be guide information that outputs a message such as "Please brighten" or "Please darken." Guide information for improving resolution may be guide information that outputs a message such as "Please increase the resolution" or "Please decrease the resolution." Guide information for improving size may be guide information that outputs a message such as "Please increase the size" or "Please decrease the size." When multiple messages are displayed in this manner, the photographer is required to perform multiple adjustments to adjust each parameter. It is assumed that the photographer will spend a considerable amount of time completing all of the multiple adjustments before capturing an image of the subject's eye.

[0128] In such a case, the adjustment determination unit 122 determines that the first guide information requires adjustment for a predetermined time or more. Then, the guide information output unit 120 outputs a voice message to the subject saying, "It will take some time until shooting begins. Please remain in a comfortable position for a while." This allows the subject to wait for shooting in a relaxed state.

[0129] It should be noted that when the above-mentioned second guide information has been output, the guide information output unit 120 may output new second guide information after a certain period of time has passed, informing the subject that shooting will soon take place. For example, the guide information output unit 120 may output a message saying, "Adjustment will soon be completed. Please do not move for a while."

[0130] (Technical Effects) Next, technical effects obtained by the information processing system 10 according to the twelfth embodiment will be described.

[0131] 21 and 22 , in the information processing system 10 according to the 12th embodiment, when first guide information indicating that adjustments of a predetermined time or more are required for the photographer is output, second guide information indicating that it will take some time before shooting is output to the subject. In this way, when it takes some time before shooting due to adjustments by the photographer, it is possible to reduce the burden on the subject.

[0132] 23 to 25 , an information processing system 10 according to a thirteenth embodiment will be described. Note that the thirteenth embodiment differs only in part of the configuration and operation from the first to twelfth embodiments described above, and other parts may be the same as the first to twelfth embodiments. Therefore, the following will describe in detail the parts that differ from the embodiments already described, and will omit a description of other overlapping parts as appropriate.

[0133] (Functional Configuration) First, the functional configuration of the information processing system 10 according to the thirteenth embodiment will be described with reference to Fig. 23. Fig. 23 is a block diagram showing the functional configuration of the information processing system according to the thirteenth embodiment. Note that in Fig. 23, the same elements as those shown in Fig. 2 are denoted by the same reference numerals.

[0134] As shown in Fig. 23 , the information processing system 10 according to the thirteenth embodiment is configured to include, as components for realizing its functions, a photographing unit 110, a guide information output unit 120, an identification unit 150, and a reward granting unit 160. That is, the information processing system 10 according to the thirteenth embodiment further includes the identification unit 150 and the reward granting unit 160 in addition to the configuration of the first embodiment (see Fig. 2 ). Each of the identification unit 150 and the reward granting unit 160 may be a processing block realized by, for example, the above-mentioned processor 11 (see Fig. 1 ).

[0135] The identification unit 150 is configured to be able to identify a filming collaborator present in the vicinity of the subject. Note that a "filming collaborator" here refers to a user who has expressed a willingness to cooperate in filming. The identification unit 150 may, for example, acquire location information from each of a plurality of pre-registered filming collaborators and identify a filming collaborator present within a predetermined distance from the subject. Since a filming collaborator identified by the identification unit 150 is present near the subject, it can be determined that the filming collaborator can actually be requested to film. Note that the subject may request the identified filming collaborator to film, or the system may do so automatically (i.e., automatic matching may be performed). The configuration for matching filming collaborators will be described in detail in another embodiment described later.

[0136] The reward granting unit 160 is configured to grant a reward to a cooperating photographer who has been authenticated using the photographing unit 110 owned by the subject for taking an eye image. The cooperating photographer who has been requested to take a photograph will pick up the device owned by the subject to take an eye image using the photographing unit 110 owned by the subject. Therefore, it can be assumed that the cooperating photographer who has been authenticated using the photographing unit 110 owned by the subject is the cooperating photographer who actually requested the eye image. Therefore, the reward granting unit 160 grants a reward to the authenticated cooperating photographer.

[0137] The authentication using the photographing means may be, for example, face authentication using a facial image. This authentication process may be performed by the information processing system 10 or by an authentication device external to the system. When performing face authentication, the face of the collaborator whose eye image has been captured is photographed by the photographing unit 110, and the face image is compared with the face image of the collaborator identified by the identifying unit 150 to perform authentication. The image used for face authentication may be a photograph of the face of the collaborator taken with the in-camera of the smartphone 50 while the collaborator is photographing the subject with the out-camera. The authentication method is not limited to face authentication, and may be, for example, iris authentication or fingerprint authentication.

[0138] (Assistant Identifying Operation) Next, the assistant identifying operation by the information processing system 10 according to the thirteenth embodiment (i.e., the operation of the identifying unit 150 described above) will be described in more detail with reference to Fig. 24. Fig. 24 is a conceptual diagram showing the assistant identifying operation by the information processing system according to the thirteenth embodiment.

[0139] As shown in Fig. 24 , the identification unit 150 identifies a filming collaborator who is within a photographable area set around the subject 60. In the example shown in Fig. 24 , a filming collaborator 70 who is within the photographable area is displayed with an icon of his / her hand raised and holding a flag. A filming collaborator 71 who is outside the photographable area is displayed with an icon of his / her hand raised but not holding a flag. A user 80 who is not a filming collaborator is displayed with an icon of his / her hand lowered. The identification unit 150 may display such images on the display unit 130.

[0140] (Flow of Operation) Next, the flow of operation by the information processing system 10 according to the thirteenth embodiment will be described with reference to Fig. 25. Fig. 25 is a flowchart showing the flow of operation of the information processing system according to the thirteenth embodiment.

[0141] 25 , in the information processing system 10 according to the thirteenth embodiment, first, a subject inputs a photography request to the information processing system 10 (step S1301). When the photography request is input, the identification unit 150 identifies a photography collaborator present in the vicinity of the subject (step S1301).

[0142] Next, the subject requests the identified cooperator to take a photograph (step S1303), and the cooperator takes an image of the subject's eyes (step S1304).

[0143] Next, the information processing system 10 authenticates the cooperator who captured the eye image (step S1305). Then, the reward granting unit 160 grants the authenticated cooperator a reward for capturing the eye image (step S1306).

[0144] The reward granting unit 160 may grant the reward as points or electronic money. The reward granted by the reward granting unit 160 may be a fixed amount or may be an amount that varies depending on the situation. For example, the reward granting unit 160 may increase the reward if the shooting goes smoothly or if the quality of the captured image is high. Alternatively, the reward granting unit 160 may increase the reward for a shooting collaborator who was located far from the subject when the subject was identified (i.e., a shooting collaborator who took the trouble to come from a distant location to take the photo).

[0145] (Technical Effects) Next, technical effects obtained by the information processing system 10 according to the thirteenth embodiment will be described.

[0146] As described with reference to Figures 23 to 25, in the information processing system 10 according to the thirteenth embodiment, a compensation for photographing is given to a cooperating photographer who is authenticated using the photographing means of the subject. In this way, the subject can request a cooperating photographer who is around the photographer to take an image of their iris. Furthermore, by paying a compensation to the cooperating photographer, it is possible to encourage active cooperation in photographing.

[0147] <Fourteenth Embodiment> An information processing system 10 according to a fourteenth embodiment will be described with reference to Figures 26 and 27. The fourteenth embodiment differs from the thirteenth embodiment described above only in part of the configuration and operation, and other parts may be the same as the first to thirteenth embodiments. Therefore, the following will describe in detail the parts that differ from the embodiments already described, and will omit explanations of other overlapping parts as appropriate.

[0148] (Functional Configuration) First, the functional configuration of the information processing system 10 according to the fourteenth embodiment will be described with reference to Fig. 26. Fig. 26 is a block diagram showing the functional configuration of the information processing system according to the fourteenth embodiment. Note that in Fig. 26, the same elements as those shown in Fig. 23 are denoted by the same reference numerals.

[0149] As shown in Fig. 26, the information processing system 10 according to the fourteenth embodiment is configured to include, as components for realizing its functions, a photographing unit 110, a guide information output unit 120, an identification unit 150, a reward granting unit 160, and a photographer determination unit 170. That is, the information processing system 10 according to the fourteenth embodiment further includes a photographer determination unit 170 in addition to the configuration of the thirteenth embodiment (see Fig. 23). The photographer determination unit 170 may be a processing block realized by, for example, the above-mentioned processor 11 (see Fig. 1).

[0150] The photographer determination unit 170 is configured to be able to determine a photographer who will actually capture the eye image from among the multiple cooperating photographers identified by the identification unit 150. That is, the photographer determination unit 170 has a function of automatically matching the subject and the cooperating photographers. Furthermore, the photographer determination unit 170 according to this embodiment particularly prioritizes, from among the multiple cooperating photographers identified, a cooperating photographer who has experience using the camera 110 (i.e., the camera 18) owned by the subject as the photographer. Note that information regarding experience using the camera 18 may be registered in advance in association with information about the cooperating photographers.

[0151] (Assistant Determination Operation) Next, the flow of the assistant determination operation (i.e., the operation of the above-mentioned photographer determination unit 170) by the information processing system 10 according to the fourteenth embodiment will be described with reference to Fig. 27. Fig. 27 is a flowchart showing the flow of the photographer determination operation by the information processing system according to the fourteenth embodiment.

[0152] 27 , the photographer determination unit 170 according to the fourteenth embodiment first acquires device information of the subject (step S1401). For example, the photographer determination unit 170 acquires information for identifying the model of the smartphone 50 equipped with the camera 18 for capturing eye images.

[0153] Next, the photographer selection unit 170 acquires terminal usage experience information from each of the multiple cooperating photographers (step S1402). That is, information for identifying terminals that the cooperating photographers have used in the past is acquired.

[0154] Next, the photographer determination unit 170 determines a photographer to take the eye image based on the device usage experience information acquired from the collaborators (step S1403). Specifically, it determines whether the device held by the subject is included in the collaborators' device usage experience information, and prioritizes collaborators with usage experience as the photographer. Note that if there are multiple collaborators with usage experience, the collaborator with the most usage experience may be prioritized as the photographer. Alternatively, the photographer may be determined using criteria other than usage experience. For example, collaborators who are close to the photographer or who have received high ratings in the past may be prioritized as the photographer.

[0155] After the photographer is determined, the photographer determination unit 170 may transmit a photography request to the cooperating photographer determined as the photographer. At this time, the photographer determination unit 170 may confirm with the subject whether or not it is OK to execute the photography request before transmitting the photography request. During this confirmation, the subject may be allowed to manually change the photographer. On the other hand, the cooperating photographer who receives the photography request may be allowed to choose whether or not to accept the photography request. If the cooperating photographer does not accept the photography request, the photographer determination unit 170 may execute a process of determining a new photographer from among the other cooperating photographers.

[0156] (Technical Effects) Next, technical effects obtained by the information processing system 10 according to the fourteenth embodiment will be described.

[0157] 26 and 27 , in the information processing system 10 according to the fourteenth embodiment, when selecting a photographer from among multiple photography collaborators who will actually capture eye images, the experience of the photographer using the photography unit 110 (in other words, the camera 18) of the device held by the subject is taken into consideration. In this way, photography collaborators with experience can be given priority in requesting photography, making it possible to capture eye images more appropriately.

[0158] Fifteenth Embodiment An information processing system 10 according to a fifteenth embodiment will be described with reference to Fig. 28. The fifteenth embodiment differs only in part of the configuration and operation from the thirteenth and fourteenth embodiments described above, and other parts may be the same as the first to fourteenth embodiments. Therefore, the following will describe in detail the parts that differ from the embodiments already described, and will omit a description of other overlapping parts as appropriate.

[0159] (Output example of guide information) First, the first guide information output by the information processing system 10 according to the fifteenth embodiment will be described with reference to Fig. 28. Fig. 28 is a plan view showing a display example of the first guide information by the information processing system according to the fifteenth embodiment.

[0160] 28 , in the information processing system 10 according to the fifteenth embodiment, the guide information acquisition unit 120 outputs first guide information to a cooperating photographer taking an eye image, for enabling the photographer to take an image of the subject's eye by setting the camera unit 110 held by the subject to a shooting-ready state. For example, as shown in the figure, the second guide information may display a message such as "Please launch the camera app first." Furthermore, the second guide information may also indicate the location of the camera app with an arrow, or display an action (e.g., tap) for launching the camera app.

[0161] Note that the guide information acquisition unit 120 may not output the second guide information described above when the filming collaborator has experience using the filming unit 110 owned by the filming subject. In other words, when it is clear that the filming collaborator knows how to make the filming possible, the output of the second guide information described above may be omitted.

[0162] (Technical Effects) Next, technical effects obtained by the information processing system 10 according to the fifteenth embodiment will be described.

[0163] 28 , in the information processing system 10 according to the fifteenth embodiment, first guide information is output for bringing the imaging unit 110 into a state in which imaging is possible. In this way, even in a situation in which the photographer is taking an image using the imaging unit 110 of the subject to be photographed (in other words, a situation in which the photographer is taking an image using someone else's camera 18), it becomes possible to take an image smoothly.

[0164] 29 and 30 , an information processing system 10 according to a 16th embodiment will be described. Note that the 16th embodiment differs only in part of the configuration and operation from the 13th to 15th embodiments described above, and other parts may be the same as the 1st to 15th embodiments. Therefore, the following will describe in detail the parts that differ from the embodiments already described, and will omit a description of other overlapping parts as appropriate.

[0165] (Functional Configuration) First, the functional configuration of the information processing system 10 according to the 16th embodiment will be described with reference to Fig. 29. Fig. 29 is a block diagram showing the functional configuration of the information processing system according to the 16th embodiment. Note that in Fig. 29, the same elements as those shown in Fig. 26 are denoted by the same reference numerals.

[0166] 29 , the information processing system 10 according to the 16th embodiment is configured to include, as components for realizing its functions, a photographing unit 110, a guide information output unit 120, an identification unit 150, a reward granting unit 160, and a photographer determination unit 170. In particular, the guide information output unit 120 according to the 16th embodiment includes a proficiency level determination unit 123.

[0167] The proficiency determination unit 123 is configured to determine whether a collaborator taking eye images is an experienced photographer with ample experience in taking eye images. For example, the proficiency determination unit 123 may determine that a collaborator who has taken eye images more than a predetermined number of times in the past is an experienced photographer. Alternatively, the proficiency determination unit 123 may determine that a collaborator whose eye images taken in the past have a high overall quality (for example, the average image quality exceeds a predetermined value) is an experienced photographer.

[0168] (Skill Determination Operation) Next, the flow of the skill determination operation by the information processing system 10 according to the sixteenth embodiment (i.e., the operation of the above-described skill determination unit 123) will be described with reference to Fig. 30. Fig. 30 is a flowchart showing the flow of the skill determination operation by the information processing system according to the sixteenth embodiment.

[0169] 30 , the proficiency level determination unit 123 according to the sixteenth embodiment first acquires the photography history information of the photography collaborator (step S1601). The photography history information may include the number of times eye images have been taken in the past, information on the quality of the eye images taken in the past, and the like.

[0170] Next, the skill level determination unit 123 determines whether the cooperating photographer is an experienced photographer based on the acquired shooting history information (step S1602). If the cooperating photographer is an experienced photographer (step S1602: YES), the guide information output unit 120 outputs a reduced amount of first guide information than usual (step S1603). On the other hand, if the cooperating photographer is not an experienced photographer (step S1602: NO), the guide information output unit 120 outputs the first guide information as usual (step S1604).

[0171] When reducing the amount of first guide information, the guide information output unit 120 may reduce the types of first guide information to be output. Alternatively, the guide information output unit 120 may reduce the number of times the first guide information is output. Furthermore, when the guide information output unit 120 reduces the amount of first guide information, it may increase the amount of second guide information. In other words, it may reduce the guide information to be output to the photographer, while increasing the guide information to be output to the subject to be photographed.

[0172] (Technical Effects) Next, technical effects obtained by the information processing system 10 according to the sixteenth embodiment will be described.

[0173] 29 and 30, in the information processing system 10 according to the sixteenth embodiment, when the cooperating photographer is an experienced photographer, the first guide information is output with a reduced amount of information. In this way, an appropriate amount of first guide information can be output according to the level of experience of the cooperating photographer. Specifically, it is possible to prevent first guide information that is unnecessary for an experienced photographer with a lot of photography experience (for example, information that is obvious to an experienced photographer) from being output.

[0174] 17th Embodiment An information processing system 10 according to a 17th embodiment will be described with reference to Fig. 31 and Fig. 32. The 17th embodiment differs only in part of the configuration and operation from the 13th to 16th embodiments described above, and other parts may be the same as the 1st to 16th embodiments. Therefore, the following will describe in detail the parts that differ from the embodiments already described, and will omit a description of other overlapping parts as appropriate.

[0175] (Functional Configuration) First, the functional configuration of the information processing system 10 according to the seventeenth embodiment will be described with reference to Fig. 31. Fig. 31 is a block diagram showing the functional configuration of the information processing system according to the seventeenth embodiment. Note that in Fig. 31, the same elements as those shown in Fig. 26 are denoted by the same reference numerals.

[0176] As shown in Fig. 31 , the information processing system 10 according to the sixteenth embodiment is configured to include, as components for realizing its functions, a photographing unit 110, a guide information output unit 120, an identification unit 150, a reward granting unit 160, a photographer determination unit 170, and a registration unit 180. That is, the information processing system 10 according to the sixteenth embodiment further includes a registration unit 180 in addition to the configuration of the fourteenth embodiment (see Fig. 26 ). The registration unit 180 may be a processing block realized by, for example, the above-mentioned processor 11 (see Fig. 1 ).

[0177] The registration unit 180 is configured to be able to register the eye image of the subject captured by the image capturing unit 110 as a registration image to be used for iris authentication. The registration unit 180 may be configured to store the registration image in, for example, the storage device 14 (see FIG. 1 ) described above. If the captured eye image satisfies a predetermined quality standard, the registration unit 180 registers the eye image as a registration image. Note that the "predetermined quality standard" is a standard set for determining whether the eye image has sufficient quality to be used as a registration image for iris authentication. For this reason, the registration unit 180 does not register low-quality eye images as registration images.

[0178] The registration unit 180 includes a proficiency determination unit 181. The proficiency determination unit 181 may have the same function as the proficiency determination unit 123 described in the sixteenth embodiment. That is, the proficiency determination unit 181 is configured to be able to determine whether or not the cooperating photographer who takes the eye images is a skilled photographer who has much experience taking eye images.

[0179] (Image Registration Operation) Next, the flow of the image registration operation (i.e., the operation of the above-described registration unit 180) by the information processing system 10 according to the seventeenth embodiment will be described with reference to Fig. 32. Fig. 32 is a flowchart showing the flow of the image registration operation by the information processing system according to the seventeenth embodiment.

[0180] 32, the registration unit 180 according to the seventeenth embodiment first acquires photographing history information from a photographing collaborator (step S1701). The photographing history information may include information on the number of times eye images have been photographed in the past, the quality of the eye images photographed in the past, and the like.

[0181] Next, the proficiency level determination unit 181 determines whether the cooperating photographer is an experienced photographer based on the acquired shooting history information (step S1702). If the cooperating photographer is an experienced photographer (step S1702: YES), the registration unit 180 raises the quality standard when registering eye images (step S1703). That is, images must be of higher quality than normal to be registered as registered images. Note that if the level of proficiency of the experienced photographer is known, the amount of increase in the quality standard may be changed depending on the level of proficiency. On the other hand, if the cooperating photographer is not an experienced photographer (step S1702: NO), the processing of step S1703 described above is omitted. That is, the predetermined quality standard remains normal.

[0182] Thereafter, the registration unit 180 determines whether the captured eye image satisfies a predetermined quality standard (step S1704). If the eye image satisfies the predetermined quality standard (step S1704: YES), the registration unit 180 registers the eye image as a registered image (step S1705). Note that if the cooperating photographer is an experienced photographer, the predetermined quality standard is raised. Therefore, eye images captured by experienced photographers are less likely to be registered as registered images. However, since the quality of captured eye images tends to be high in the case of experienced photographers, even if the predetermined quality standard is raised, problems such as poor registration will not occur.

[0183] On the other hand, if the eye image does not satisfy the predetermined quality standard (step S1704: NO), the processing of step S1705 described above is omitted. That is, the registration unit 180 does not register the eye image as a registered image. In this case, the registration unit 180 may output an instruction to capture a new eye image.

[0184] (Technical Effects) Next, technical effects obtained by the information processing system 10 according to the seventeenth embodiment will be described.

[0185] 31 and 32, in the information processing system 10 according to the seventeenth embodiment, when an experienced photographer takes an eye image, the quality standard for registering the captured eye image as a registered image is set high. In this way, when an experienced photographer is requested to take a photograph, it becomes possible to register an image of higher quality.

[0186] The scope of each embodiment also includes a processing method in which a program that operates the configuration of each embodiment to realize the functions of the above-described embodiments is recorded on a recording medium, the program recorded on the recording medium is read as code, and the program is executed on a computer. In other words, a computer-readable recording medium is also included in the scope of each embodiment. Furthermore, each embodiment includes not only a recording medium on which the above-described program is recorded, but also the program itself.

[0187] Examples of recording media that can be used include floppy disks, hard disks, optical disks, magneto-optical disks, CD-ROMs, magnetic tapes, non-volatile memory cards, and ROMs. Furthermore, the scope of each embodiment is not limited to programs that execute processes by themselves, but also includes programs that execute processes by operating on an OS in conjunction with other software or expansion board functions. Furthermore, the program itself may be stored on a server, and part or all of the program may be downloadable from the server to a user terminal. The program may be provided to the user in, for example, a SaaS (Software as a Service) format.
