[0013]
　(Functional Configuration)

[0018]
　The engine switching unit 104 is configured to switch the engine used by the process execution unit 102 based on the identification information extracted by the identification information extraction unit 103 .

[0020]

[0021]
　The CPU 11 reads computer programs. For example, the CPU 11 is configured to read computer programs stored in at least one of the RAM 12, ROM 13 and storage device 14. FIG. Alternatively, the CPU 11 may read a computer program stored in a computer-readable recording medium using a recording medium reader (not shown). The CPU 11 may acquire (that is, read) a computer program from a device (not shown) arranged outside the information processing system 1 via the network interface. The CPU 11 controls the RAM 12, the storage device 14, the input device 15 and the output device 16 by executing the read computer program. Especially in this embodiment, when the computer program read by the CPU 11 is executed, a functional block for switching engines and executing processing is realized in the CPU 11 (see FIG. 1).
[0022]
　The information processing system 1 according to the first embodiment may include an accelerator (not shown) in addition to the CPU 11 described above. The accelerator is hardware added to increase the processing performance of the information processing system 1, and is configured to be able to execute processing using an engine, similar to the CPU 11.

　(Flow of Operation)
　Next, the flow of operation of the information processing system 1 according to the first embodiment will be described with reference to FIG. FIG. 3 is a flow chart showing the operation flow of the information processing system according to the first embodiment.
[0029]
　As shown in FIG. 3, when the information processing system 1 according to the first embodiment operates, the processing information acquisition unit 101 first acquires processing information (step S11). After that, the identification information extraction unit 103 extracts identification information from the processing information (step S12).
[0030]

[0031]
　(Technical Effects)
　Next, technical effects obtained by the information processing system 1 according to the first embodiment will be described.
[0032]
　As described with reference to FIGS. 1 to 3, in the information processing system 1 according to the first embodiment, the engine used by the processing execution unit 102 is switched before the processing execution unit 102 executes processing. Therefore, the processing execution unit 102 can execute processing in a more appropriate state than when the engine is not switched. Also, engine switching is performed based on the identification information extracted from the processing information. Therefore, switching to an engine suitable for the process executed by the process execution unit 102 can be achieved.
[0033]
　
　Next, an information processing system according to a second embodiment will be described with reference to FIGS. 4 to 6. FIG. It should be noted that the second embodiment differs from the above-described first embodiment only in a part of configuration and operation, and other parts are generally the same. Therefore, in the following, portions different from the first embodiment will be described in detail, and descriptions of other overlapping portions will be omitted as appropriate.
[0034]
　(Functional Configuration)
　First, the functional configuration of the information processing system according to the second embodiment will be described with reference to FIG. FIG. 4 is a block diagram showing the functional configuration of an information processing system according to the second embodiment. In FIG. 4, the same symbols are assigned to the same components as those shown in FIG.
[0035]
　In FIG. 4 , the information processing system 1 according to the second embodiment is configured to be able to execute processing for generating data used by the biometrics authentication device 30 using video data input from the camera 20 . Note that the camera 20 is configured to be capable of capturing an image of a subject for whom biometric authentication is performed. The biometric authentication device 30 is configured to be able to perform biometric authentication (here, face authentication) of a subject. The biometric device 30 may be configured as a cloud. As for the specific biometric authentication method, an existing method can be appropriately adopted, so detailed description thereof will be omitted here.
[0036]
　The information processing system 1 according to the second embodiment includes the components of the first embodiment (in addition to the components shown in FIG. 1), a hardware information storage unit 105, and an engine storage unit 106. FIG.
[0037]
　The hardware information storage unit 105 is configured to store configuration information indicating the hardware configuration of the information processing system 1 . Note that when the hardware configuration of the information processing system 1 is changed, the configuration information stored in the hardware information storage unit 105 is updated as appropriate. The configuration information stored in the hardware information storage unit 105 can be appropriately read by the engine switching unit 104 .
[0038]
　The engine storage unit 106 stores multiple engines that can be used by the process execution unit 102 . Engines stored in the engine storage unit 106 may be added, deleted, or upgraded. The engine stored in the engine storage unit 106 can be appropriately read by the engine switching unit 104 . The engine switching unit 104 is configured to be able to switch between engines by reading an engine stored in the engine storage unit 106 and loading it into the process execution unit 102 .
[0039]
　(Flow of Operation)
　Next, the flow of operation of the information processing system 1 according to the second embodiment will be described with reference to FIG. FIG. 5 is a flow chart showing the operation flow of the information processing system according to the second embodiment.
[0040]
　As shown in FIG. 5, when the information processing system 1 according to the second embodiment operates, the engine switching unit 104 first acquires configuration information from the hardware information storage unit 105 (step S21). Note that the process of acquiring the configuration information may be executed when there is a possibility that the hardware configuration of the information processing system 1 has changed. For example, the engine switching unit 104 may acquire configuration information when the information processing system 1 is activated.
[0041]
　Subsequently, the processing information acquisition unit 101 acquires video data from the camera 20 (step S22). Then, the processing information acquisition unit 101 determines whether or not the quality of the video data is appropriate (step S23). Specifically, the processing information acquisition unit 101 determines whether or not the quality of the acquired video data is high enough to allow the processing execution unit 102 to appropriately execute the processing. The quality of video data can be determined, for example, based on the luminance value of each pixel.
[0042]
　When it is determined that the quality of the video data is not appropriate (step S23: NO), the processing information acquisition unit 101 executes processing for correcting the video data (step S24). In other words, the processing information acquisition unit 101 executes processing for improving the quality of video data. For example, the processing information acquisition unit 101 executes backlight correction processing, image sharpening processing, or the like on video data.
[0043]
　When it is determined that the quality of the video data is appropriate (step S23: YES), or when the correction processing of the video data is executed, the identification information extracting unit 103 detects an object from the video data. is executed (step S25). Specifically, the identification information extraction unit 103 executes a process of detecting the face and human figure of the target person appearing in the video data. Note that this process may be executed by the process execution unit 102 .
[0044]
　Subsequently, the identification information extraction unit 103 executes a process of extracting attributes of the extracted object (that is, the subject) (step S26). The “attribute” here is information indicating the condition of the subject, and is extracted as a specific example of identification information. The extracted attributes affect the processing executed by the processing execution unit 102. For example, in the case of generating information used for facial authentication of a subject, even if the presence or absence of a mask or sunglasses is extracted as an attribute. good.
[0045]
　Subsequently, the engine switching unit 104 causes the processing execution unit 102 to perform It is determined whether or not processing (ie, processing for generating data used for biometric authentication) can be executed with the current engine (step S27). Specifically, the engine switching unit 104 uses the processing information acquired by the processing execution unit 102 to determine whether processing for generating data used for biometric authentication can be executed. Alternatively, the engine switching unit 104 may use the processing information acquired by the processing execution unit 102 to determine whether or not the process of generating data used for biometric authentication can be executed at a sufficient speed. Alternatively, the engine switching unit 104 may use the processing information acquired by the processing execution unit 102 to determine whether or not the process of generating data used for biometric authentication can be executed with sufficiently low power.
[0046]
　If it is determined that the process can be executed with the current engine (step S27: YES), the engine switching unit 104 does not switch the engine used by the process execution unit 102. Therefore, the process executing unit 102 executes the process of generating data used for biometric authentication with the current engine (for example, the initialized engine) (step S28).
[0047]
　On the other hand, if it is determined that the process should not be executed with the current engine (step S27: NO), the engine switching unit 104 switches the engine used by the process execution unit 102 (step S29). Specifically, the engine switching unit 104 reads an engine capable of executing a process corresponding to the acquired process information from among the plurality of engines stored in the engine storage unit 106, and selects the engine of the process execution unit 102. replace with Alternatively, the engine switching unit 104 reads the engine that can execute the processing corresponding to the acquired processing information fastest among the plurality of engines stored in the engine storage unit 106, and selects the engine of the processing execution unit 102. You can replace it. Alternatively, the engine switching unit 104 reads an engine that can execute the process corresponding to the acquired processing information with the lowest power consumption from among the plurality of engines stored in the engine storage unit 106, You can replace the engine. Furthermore, the engine switching unit 104 may switch the engine using the configuration information acquired in step S21. For example, the engine storage unit 106 stores a plurality of engines corresponding to various hardware configurations, and the engine switching unit 104 reads the engine suitable for the current hardware configuration from among them, and 102 engine may be replaced. After that, the process executing unit 102 uses the switched engine to execute a process of generating data used for biometric authentication (step S28).
[0048]
　Among the above-described processes, the process of determining whether or not the quality of the video data is appropriate (that is, the process of step S23) does not necessarily have to be executed. In this case, regardless of the quality of the video data acquired in step S22, the process of detecting an object using the video data (that is, step S24) may be executed.
[0049]
　Further, among the processes described above, the process of determining whether or not the process can be executed with the current engine (that is, the process of step S27) does not necessarily have to be executed. In this case, the engine switching unit 104 may perform the process of switching the engine used by the process execution unit 102 (that is, step S29) regardless of whether or not the process should be executed with the current engine. However, the result of switching the engine may be the same engine as the current one (that is, the engine may not be switched substantially).
[0050]
　(Specific Operation Example)
　Next, a specific operation example of the information processing system 1 according to the second embodiment will be described with reference to FIG. FIG. 6 is an image diagram showing an operation example of the information processing system according to the second embodiment.
[0051]
　In the example shown in FIG. 6, the camera 20 is arranged at a position capable of capturing an image of a subject 500 approaching a door that can be unlocked by biometric authentication. The information processing system 1 is configured to be able to execute a process of extracting a feature amount used for face authentication from the subject's image acquired from the camera 20 . The biometric authentication device 30 is configured to perform face authentication using the feature amount extracted by the information processing system 1 and unlock the door based on the authentication result.
[0052]
　In FIG. 6( a ), when the subject 500 enters the imaging range of the camera 20 , the identification information extraction unit 103 detects the face and figure of the subject 500 . That is, a process of detecting the target person 500 and detecting the face area from the image data of the target person 500 is executed. This process is executed when the target person 500 is relatively away from the door (for example, several meters or more away).
[0053]
　In FIG. 6B, when the target person 500 is detected, the identification information extraction unit 103 determines whether or not the target person 500 has a mask from the target person's face image (that is, the face area extracted from the video data). do. Note that existing techniques can be appropriately adopted for a specific technique for determining the presence or absence of a mask, so detailed description thereof will be omitted here.
[0054]
　When it is determined whether or not the subject 500 has a mask, the engine switching unit 104 determines whether or not to switch the engine. Specifically, when the target person is not wearing a mask, the engine switching unit 104 determines that the engine need not be switched (that is, the normal engine may remain). On the other hand, if the subject wears a mask, the engine switching unit 104 determines to switch the engine (that is, to switch to an engine capable of extracting feature amounts even when the mask is worn).
[0055]
　In FIG. 6C, the process execution unit 102 executes a process of extracting a feature amount using an engine according to whether the subject 500 has a mask. Therefore, even if the target person 500 is wearing a mask (in other words, it is difficult to extract the feature amount with a normal engine), the feature amount can be extracted appropriately. The biometric authentication device 30 performs face authentication using the feature quantity extracted in this manner. If the result of face authentication is successful, the door is instructed to be unlocked.
[0056]
　(Modification)
　In the above, the case where the engine is switched based on the presence or absence of the mask (that is, the case where the engine that detects the feature amount of the subject with the mask and the engine that detects the feature amount of the subject without the mask are switched) ), the switch to other engines may be performed.
[0057]
　For example, the engine switching unit 104 may be an engine that executes processing for estimating the age of the subject 500, an engine that executes processing for estimating the sex of the subject, an engine that executes processing for estimating the line of sight of the subject, or a camera. 20 may be switched to an engine that counts the number of people imaged. Switching to such an engine has beneficial effects, for example, in situations where individual identification is not required (eg, marketing applications).
[0058]
　In addition, the engine switching unit 104 may be an engine that executes processing for detecting crowds, an engine that executes processing for detecting individual behavior, an engine that executes processing for detecting behavior of crowds, or an IDM (Image Data Mining). ) may be performed. IDM can implement, for example, face search, retention search, related person search, or common person search.
[0059]
　(Technical Effects)
　Next, technical effects obtained by the information processing system 1 according to the second embodiment will be described.
[0060]
　As described with reference to FIGS. 4 to 6, in the information processing system 1 according to the second embodiment, the process of extracting the feature amount used for face authentication is executed using an appropriate engine according to the state of the subject. be able to. Therefore, it is possible to avoid a situation in which appropriate face authentication cannot be performed due to the subject's condition.
[0061]
　Also, in the second embodiment, the hardware configuration is taken into consideration when switching engines. Therefore, switching to a more appropriate engine becomes possible as compared with the case of using only the identification information. Furthermore, in the second embodiment, when switching engines, it is determined whether or not processing can be performed with the current engine. Therefore, unnecessary engine switching can be prevented. In addition, in the second embodiment, since the engine storage unit 106 that stores a plurality of engines is provided, engine switching can be performed relatively easily.
