Abstract: To improve efficiency of road surveillance, a road surveillance system includes a detection unit 122 and a processing unit 134. The detection unit 122 detects a road state being a state of an object on a road by processing an image in which the road is captured. The processing unit 134 performs, when the road state satisfies a first criterion, any of notification processing of making a notification of the road state that satisfies the first criterion according to notification setting related to the notification, and change-related processing related to a change in the notification setting, based on whether a second criterion is satisfied. The second criterion is a criterion related to a determination result of whether the road state satisfies the first criterion.

Abstract: A road surveillance system includes a video acquisition unit, a target determination unit, and a display control unit. The video acquisition unit acquires a video that captures a road. The target determination unit determines, based on a result of comparison between at least one frame image constituting the video and a reference image, and a first criterion, whether the at least one frame image is an analysis target. The display control unit causes a display unit to display information based on a result of the determination. The display control unit includes a first control unit and a second control unit. The first control unit causes the display unit to display an analysis result of at least one frame image being determined to be an analysis target. The second control unit causes the display unit to display detection information indicating that a frame image not being an analysis target is detected.

Abstract: An analysis apparatus detects persons from a first image generated by a first camera that captures a vehicle, detects the number of occupants in the vehicle captured in the first image, detects persons from a second image generated by a second camera that captures the vehicle, detects the number of occupants in the vehicle captured in the second image, determines whether or not the first image and the second image satisfy a predetermined condition, and decides, in a case where the first image and the second image satisfy the predetermined condition, the number of occupants in the vehicle with use of the number of occupants in the vehicle captured in the first image and the number of occupants in the vehicle captured in the second image.
