System, information processing method, method of manufacturing product, and recording medium with images of object that moves relative to cameras being captured at predetermined intervals and having different image capture times

A system includes an information processing device. The information processing device is configured to acquire an image group from each of a plurality of cameras. The image group includes a plurality of images of an object that moves relative to each of the plurality of cameras. The plurality of images are captured by a corresponding camera at predetermined intervals and having different image capture times. The information processing device is configured to calculate an amount of movement of the object relative to each of the plurality of cameras, based on the image group acquired from each of the plurality of cameras. The information processing device is configured to detect a lag between image capture timings of the plurality of cameras, by using the amount of movement of the object relative to each of the plurality of cameras.
