Camera spectral sensitivity functions relate scene radiance with captured RGB
triplets. They are important for many computer vision tasks that use color
information, such as multispectral imaging, and color constancy.
We create a database of 28 cameras covering a variety of types. The database
contains the spectral sensitivity functions for 28 cameras, including
professional DSLRs, point-and-shoot, industrial and mobile phone camera. We use
a spectrometer PR655 from Photo Research Inc., a light source and monochrometer
combined with an integrating sphere to do the measurement. Each measurement
starts from wavelength 400nm to 720nm in an interval of 10nm. Measured Sensitivities are normalized to 1 for RGB channels seperately. The database is in the form
of a text file. Each entry starts with camera name and follows by measured
spectral sensitivities in red, green and blue channel.
