Data management system and data management method

Abstract

The support system (1000) comprises a camera (30), an illumination device (260), and a time calculation unit. The camera (30) and the illumination device (260) each receive a time-synchronized imaging instruction signal. The camera (30) images the controlled device (220) based on the imaging instruction signal. The illumination device (260) illuminates the controlled device (220) with light in synchronization with the imaging by the camera (30) based on the imaging instruction signal. The time calculation unit calculates the imaging time based on the exposure period in imaging by the camera (30), the illumination period in illumination by the illumination device (260), and the imaging instruction signal. The time calculation unit manages the image data, which represents the image obtained by imaging by the camera (30), in association with the imaging time.
