Deep Hybrid Camera Deblurring
Jaesung Rim Junyong Lee Heemin Yang Sunghyun Cho
Mobile cameras, despite their significant advancements, still face low-light
challenges due to compact sensors and lenses, leading to longer exposures and
motion blur. Traditional solutions like blind deconvolution and learning-based
methods often fall short in handling ill-posedness of the deblurring problem.
To address this, we propose a novel deblurring framework for multi-camera
smartphones, utilizing a hybrid imaging technique. We simultaneously capture a
long exposure wide-angle image and ultra-wide burst images from a smartphone,
and use the sharp burst to estimate blur kernels for deblurring the wide-angle
image. For learning and evaluation of our network, we introduce the HCBlur
dataset, which includes pairs of blurry wide-angle and sharp ultra-wide burst
images, and their sharp wide-angle counterparts. We extensively evaluate our
method, and the result shows the state-of-the-art quality.
