Abstract
A sensor package includes a semiconductor sensor chip having multiple light sensitive regions each of which defines a respective light sensitive channel. An optical filter structure is disposed over the sensor chip and includes filters defining respective spectral functions for different ones of the light sensitive channels. In particular, the optical filter structure includes at least three optical filters defining spectral functions for tristimulus detection by a first subset of the light sensitive channels, and at least one additional optical filter defining a spectral function for spectral detection by a second subset of the light sensitive channels encompassing a wavelength range that differs from that of the first subset of light sensitive channels.
