  Abstract

With the development of technology, electronic devices have been miniaturized and users can wear devices. Among wearable devices, wearable cameras can be used for recording personal daily activities. This type of camera is directly affected by the user"s movements, so the captured picture often shakes. In most cases, this device is used to periodically record the user"s daily life, so there is a need to reduce the percentage of shaky photos. In this paper, we propose a real-time resolution control system that enables a small wearable camera to operate efficiently. The proposed system works with the Android application to determine the threshold value adaptively. We developed a small wearable camera and an Android application for the system implementation. The proposed system showed 6% higher accuracy and 17.8% better recall than the case of adjusting the resolution with a fixed threshold without considering the surrounding environment.
