an extraction means that extracts person attribute information representing an attribute of a person in a captured image obtained by capturing an image of the target place; and a detection means that detects a predetermined person in the captured image based on the reference attribute information and the person attribute information. ## Claims ### Claim 1 An information processing device comprising: a memory in which instructions are stored; and at least one processor configured to execute the instructions to: acquire environment information representing a surrounding environment of a target place from another information processing device connected via a network; acquire, based on the environment information, reference attribute information representing an attribute of a person corresponding to the target place and reference action information associated with the target place, from a storage device in which the reference attribute information and the reference action information are stored; extract person attribute information representing an attribute of a person and person action information of the person in a captured image obtained by capturing an image of the target place; and detect, in the caputred image, a predetermined person performing a predetermined action in the target place, based on the reference attribute information, the reference action information, the person attribute information, and the person action information. ### Claim 2 (depends on 1) The information processing device according to claim 1, wherein the at least one processor is configured to execute the instructions to detect the predetermined person in the captured image based on the reference attribute information representing attributes of a plurality of persons and the person attribute information representing an attribute of one person or attributes of a plurality of persons. ### Claim 3 (depends on 1) The information processing device according to claim 1, wherein the at least one processor is configured to execute the instructions to detect, in a case where the person attribute information agrees with the reference attribute information in accordance with a predetermined criterion or does not agree with the reference attribute information in accordance with the predetermined criterion, the predetermined person in the captured image corresponding to the person attribute information. ### Claim 4 (depends on 1) The information processing device according to claim 1, wherein: the reference attribute information is set to correspond to each of the target place and the surrounding environment of the target place; and the at least one processor is configured to execute the instructions to detect the predetermined person in the captured image based on the reference attribute information set corresponding to each of the target place at which the captured image is captured and the surrounding environment and the person attribute information. ### Claim 5 (depends on 1) The information processing device according to claim 1, wherein: the person action information represents an action of the person in the captured image. ### Claim 6 (depends on 1) The information processing device according to claim 1, wherein the at least one processor is configured to execute the instructions to: extract the attribute of the person that is information representing an age of the person, information representing a gender of the person, or information representing personal belongings of the person in the captured image obtained by capturing the image of the target place; and generate and store the reference attribute information corresponding to the target place based on the extracted attribute of the person. ### Claim 7 A non-transitory computer-readable medium storing a program comprising instructions for causing an information processing device to execute processes of: acquiring environment information representing a surrounding environment of a target place from another information processing device connected via a network; acquiring, based on the environment information, reference attribute information representing an attribute of a person corresponding to the target place and reference action information associated with the target place, from a storage device in which the reference attribute information and the reference action information are stored; extracting person attribute information representing an attribute of a person and person action information of the person in a captured image obtained by capturing an image of the target place; and detecting, in the captured image, a predetermined person performing a predetermined action in the target place, based on the reference attribute information, the reference action information, the person attribute information, and the person action information. ### Claim 8 An information processing method performed by a an information processing device and comprising: acquiring environment information representing a surrounding environment of a target place from another information processing device connected via a network; acquiring, based on the environment information, reference attribute information representing an attribute of a person corresponding to the target place and reference action information associated with the target place, from a storage device in which the reference attribute information and the reference action information are stored; extracting person attribute information representing an attribute of a person and person action information of the person in a captured image obtained by capturing an image of the target place; and detecting, in the captured image, a predetermined person performing a predetermined action in the target place, based on the reference attribute information, the reference action information, the person attribute information, and the person action information. ### Claim 9 (depends on 8) The information processing method according to claim 8, wherein: the reference attribute information is set to correspond to each of the target place and the surrounding environment of the target place; and the predetermined person in the captured image is detected based on the reference attribute information set corresponding to each of the target place at which the captured image is captured and the surrounding environment and the person attribute information. ### Claim 10 (depends on 8) The information processing method according to claim 8, wherein the person action information represents an action of the person in the captured image. ### Claim 11 (depends on 8) The information processing method according to claim 8, further comprising: extracting the attribute of the person that is information representing an age of the person, information representing a gender of the person, or information representing personal belongings of the person in the captured image obtained by capturing the image of the target place; and the reference attribute information corresponding to the target place based on the extracted attribute of the person. ### Claim 12 (depends on 1) The information processing device according to claim 1, wherein the environment information includes at least one of date, season, and weather.
