In this paper, we present GyroDeblurNet, a novel single image deblurring method that utilizes a gyro sensor to effectively resolve the ill-posedness of image deblurring.The gyro sensor provides valuable information about camera motion that can significantly improve deblurring quality.However, effectively exploiting real-world gyro data is challenging due to significant errors from various sources.To handle these errors, GyroDeblurNet is equipped with two novel neural network blocks: a gyro refinement block and a gyro deblurring block.The gyro refinement block refines the erroneous gyro data using the blur information from the input image.The gyro deblurring block removes blur from the input image using the refined gyro data and further compensates for gyro error by leveraging the blur information from the input image.For training a neural network with erroneous gyro data, we propose a training strategy based on the curriculum learning.We also introduce a novel gyro data embedding scheme to represent real-world intricate camera shakes.Finally, we present both synthetic and real-world datasets for training and evaluating gyro-based single image deblurring.Our experiments demonstrate that our approach achieves state-of-the-art deblurring quality by effectively utilizing erroneous gyro data.
