Abstract: An information processing system providing a service by using a video captured by an imaging device includes a processor; and a storage storing instructions causing the processor to execute processes of: acquiring video data from the imaging device, estimating an installation angle of the imaging device based on the video data, generating a detection model for detecting a predetermined target from the video based on the installation angle, and providing the service by inputting the video data to the detection model.

Abstract: A portable imaging device is configured to: obtain video data through shooting; perform a first digital image processing on the video data; and stop the first digital image processing when performing a second digital image processing on the video data while the first digital image processing is being performed. The second digital image processing is different from the first digital image processing.

Abstract: A system according to an embodiment of the present disclosure is a system for displaying a video captured by a camera connected to a network. The system is configured to set, in response to instructions from a user, a first threshold regarding the number of people staying in a target area and a second threshold regarding a period of time during which the people stay in the target area, measure the number of people staying in the target area and a period of time during which the people stay in the target area, generate a thumbnail showing a video when the number of people staying in the target area for a period of time equal to or longer than the second threshold is equal to or greater than the first threshold, and display the thumbnail generated.

Abstract: An aspect of the present disclosure provides an information processing system configured to process a captured image captured by an image-capturing apparatus including an infrared cut filter. In this information processing system, based on the captured image, a defect relating to the infrared cut filter is detected. Information on the defect is output.

Abstract: According to an aspect of the present invention, an information processing system is provided. The information processing system is configured to display a captured image regarding a cashier on a screen. The screen includes a timeline regarding the captured image. When the captured image meets a predetermined condition at timing when refund processing is performed at the cashier, an object regarding refund fraud is displayed in association with the timeline.
