  AI-powered automatic camera scene detection mode is nowadays available in
nearly any modern smartphone, though the problem of accurate scene prediction
has not yet been addressed by the research community. This paper for the first
time carefully defines this problem and proposes a novel Camera Scene Detection
Dataset (CamSDD) containing more than 11K manually crawled images belonging to
30 different scene categories. We propose an efficient and NPU-friendly CNN
model for this task that demonstrates a top-3 accuracy of 99.5% on this dataset
and achieves more than 200 FPS on the recent mobile SoCs. An additional
in-the-wild evaluation of the obtained solution is performed to analyze its
performance and limitation in the real-world scenarios. The dataset and
pre-trained models used in this paper are available on the project website.
