and at least one processor configured to execute the instructions to: acquire high-risk time and space information indicating a spatial region with an increased possibility of an accident occurring or of a crime being committed and at least a corresponding time slot; identify and acquire a video to be analyzed based on the high-risk time and space information; analyze the video to acquire information on a possible surveillance target that is a person who has caused a crime or an accident before or a vehicle possessed by the person, the information on the possible surveillance target including a number of possible surveillance targets counted within the spatial region and in the corresponding time slot; determine a degree of priority of the spatial region and the corresponding time slot based on the information on the possible surveillance target; and identify, from among the spatial region and the corresponding time slot indicated by the high-risk time and space information, a spatial region where surveillance is to be conducted, which is at least a portion of the spatial region, and a time slot when surveillance is to be conducted, on a basis of the information on the possible surveillance target and the degree of priority, wherein the time slot when surveillance is to be conducted includes a first time of starting the surveillance and a second time of ending the surveillance. ### Claim 2 (depends on 1) The information processing apparatus according to claim 1, the processor is further configured to: acquire information of a possible victim of an accident or a crime; and adjust at least one of the spatial region where surveillance is to be conducted or the time slot when surveillance is to be conducted using the information of the possible victim. ### Claim 3 (depends on 1) The information processing apparatus according to claim 1, the processor is further configured to: acquire environmental information of a region included in the video, on a basis of the video or information for identifying a place of the video; and adjust at least one of the spatial region where surveillance is to be conducted or the time slot when surveillance is to be conducted using the environmental information. ### Claim 4 An information processing method executable by a computer, the method comprising: acquiring high-risk time and space information indicating a spatial region with an increased possibility of an accident occurring or of a crime being committed and at least a corresponding time slot; identifying and acquiring a video to be analyzed based on the high-risk time and space information; analyzing the video to acquire information on a possible surveillance target that is a person who has caused a crime or an accident before or a vehicle possessed by the person, the information on the possible surveillance target including a number of possible surveillance targets counted within the spatial region and in the corresponding time slot; determining a degree of priority of the spatial region and the corresponding time slot based on the information on the possible surveillance target; and identifying, from among the spatial region and the corresponding time slot indicated by the high-risk time and space information, a spatial region where surveillance is to be conducted, which is at least a portion of the spatial region, and a time slot when surveillance is to be conducted, on a basis of the information on the possible surveillance target and the degree of priority, wherein the time slot when surveillance is to be conducted includes a first time of starting the surveillance and a second time of ending the surveillance. ### Claim 5 (depends on 4) The information processing method executable by the computer according to claim 4, the method further comprising: acquiring information of a possible victim of an accident or a crime; and adjusting at least one of the spatial region where surveillance is to be conducted or the time slot when surveillance is to be conducted using the information of the possible victim. ### Claim 6 (depends on 4) The information processing method executable by the computer according to claim 4, the method further comprising: acquiring environmental information of a region included in the video, on a basis of the video or information for identifying a place of the video; and adjusting at least one of the spatial region where surveillance is to be conducted or the time slot when surveillance is to be conducted using the environmental information. ### Claim 7 A non-transitory computer readable storage medium storing a program for causing a computer to execute a method, the method comprising: acquiring high-risk time and space information indicating a spatial region with an increased possibility of an accident occurring or of a crime being committed and at least a corresponding time slot; identifying and acquiring a video to be analyzed based on the high-risk time and space information; analyzing the video to acquire information on a possible surveillance target that is a person who has caused a crime or an accident before or a vehicle possessed by the person, the information on the possible surveillance target including a number of possible surveillance targets counted within the spatial region and in the corresponding time slot; determining a degree of priority of the spatial region and the corresponding time slot based on the information on the possible surveillance target; and identifying, from among the spatial region and the corresponding time slot indicated by the high-risk time and space information, a spatial region where surveillance is to be conducted, which is at least a portion of the spatial region, and a time slot when surveillance is to be conducted, on a basis of the information on the possible surveillance target and the degree of priority, wherein the time slot when surveillance is to be conducted includes a first time of starting the surveillance and a second time of ending the surveillance. ### Claim 8 (depends on 7) The non-transitory computer readable storage medium according to claim 7, the method further comprising: acquiring information of a possible victim of an accident or a crime; and adjusting at least one of the spatial region where surveillance is to be conducted or the time slot when surveillance is to be conducted using the information of the possible victim. ### Claim 9 (depends on 7) The non-transitory computer readable storage medium according to claim 7, the method further comprising: acquiring environmental information of a region included in the video, on a basis of the video or information for identifying a place of the video;
