Video deblurring aims to restore sharp frames from blurred video clips. Despite notable progress in video deblurring works, it is still a challenging problem because of the loss of motion information during the duration of the exposure time. Since event cameras can capture clear motion information asynchronously with high temporal resolution, several works exploit the event camera for deblurring as they can provide abundant motion information. However, despite these approaches, there were few cases of actively exploiting the long-range temporal dependency of videos. To tackle these deficiencies, we present an event-based video deblurring framework by actively utilizing temporal information from videos. To be specific, we first introduce a frequency-based cross-modal feature enhancement module. Second, we propose event-guided video alignment modules by considering the valuable characteristics of the event and videos. In addition, we designed a hybrid camera system to collect the first real-world event-based video deblurring dataset. For the first time, we build a dataset containing synchronized high-resolution real-world blurred videos and corresponding sharp videos and event streams. Experimental results validate that our frameworks significantly outperform the state-of-the-art frame-based and event-based video deblurring works in the various datasets.
