|a Low-light raw image denoising is an essential task in computational photography, to which the learning-based method has become the mainstream solution. The standard paradigm of the learning-based method is to learn the mapping between the paired real data, i.e., the low-light noisy image and its clean counterpart. However, the limited data volume, complicated noise model, and underdeveloped data quality have constituted the learnability bottleneck of the data mapping between paired real data, which limits the performance of the learning-based method. To break through the bottleneck, we introduce a learnability enhancement strategy for low-light raw image denoising by reforming paired real data according to noise modeling. Our learnability enhancement strategy integrates three efficient methods: shot noise augmentation (SNA), dark shading correction (DSC) and a developed image acquisition protocol. Specifically, SNA promotes the precision of data mapping by increasing the data volume of paired real data, DSC promotes the accuracy of data mapping by reducing the noise complexity, and the developed image acquisition protocol promotes the reliability of data mapping by improving the data quality of paired real data. Meanwhile, based on the developed image acquisition protocol, we build a new dataset for low-light raw image denoising. Experiments on public datasets and our dataset demonstrate the superiority of the learnability enhancement strategy
