Abstract: An information processing apparatus determines a direction (first direction (12)) from a sensor (10) toward a moving object (20) by detecting the moving object (20) using the sensor (10). The information processing apparatus causes a camera (30) to perform imaging while moving the optical axis direction (34) of the camera (30) along the first direction (12). As a result, a plurality of captured images (32), each of which is captured in the different direction, are generated by the camera (30). The information processing apparatus (2000) detects the moving object (20) by performing image analysis on the captured image (32).

Abstract: In a recovery level estimation device, an image acquisition means acquires images in which eyes of a patient are captured. An eye movement feature extraction means extracts an eye movement feature which is a feature of an eye movement based on the images. A recovery level estimation means estimates a recovery level of the patient based on the eye movement feature by using a recovery level estimation model which has been learned by machine learning in advance.
