Abstract

In this article, we propose a comprehensive objective metric for estimating digital camera system performance. Using the DXOMARK RAW protocol, image quality degradation indicators are objectively quantified, and the information capacity is computed. The model proposed in this article is a significant improvement over previous digital camera systems evaluation protocols, wherein only noise, spectral response, sharpness, and pixel count were considered. In the proposed model we do not consider image processing techniques, to only focus on the device intrinsic performances. Results agree with theoretical predictions. This work has profound implications in RAW image testing for computer vision and may pave the way for advancements in other domains such as automotive or surveillance camera.
