The accurate rendition of color in camera, imaging and lighting systems is highly valued by consumers and professional buyers. Developments in color sensing have recently seen the introduction of a new generation of multi-channel spectral sensors which for the first time provide for chip-scale spectral analysis of incident light – a more detailed type of information than color or image sensors provide.

This white paper describes how a spectral sensor IC provides accurate color measurements backed by reliable detection of the signature of any kind of visible light source. It then explains its use cases in high-performance cameras and imaging equipment, in tunable and human-centric lighting systems, and for sophisticated environment awareness in wearable devices.
