Abstract
Ambient light analysis methods, imaging devices, and articles of manufacture are described. According to one aspect, an ambient light analysis method includes emitting light using a source, first filtering the light of the source providing first filtered light, first receiving the first filtered light using an imaging device, providing a first response of the imaging device to the first filtered light, second filtering ambient light providing second filtered light, second receiving the second filtered light using the imaging device, providing a second response of the imaging device to the second filtered light, and determining information regarding a spectral power distribution of the ambient light using the first response and the second response.
