This publication describes systems and techniques directed to enhancing High Dynamic Range (HDR) imaging by identifying and understanding the lighting environment of a scene for image capture. Natural light (e.g., outdoor sky, sunlight) is identified and differentiated from artificial light (e.g., light-emitting diode (LED), fluorescent, halogen, incandescent lighting) for advanced metering and optimal exposure control. Exposure is adjusted relative to the differentiated lighting for final image capture. Regions of the scene are differentiated by mapping different weights to the dynamic range detected. This comprehensive understanding of the scene captures the most important region of interest (e.g., from the viewer’s perspective) within a good exposure value.
