Document Type and Number:
Japanese Patent JP2005294825
Kind Code:
A
Abstract:
To provide a color sensor which can exhibit performance closer to that expected by design.
A color sensor (50, 200) for measuring light from a light source comprises: multiple photodetectors (51-53); multiple primary color filters (61-63), each of which includes a material layer between the light source and a corresponding one of the photodetectors (51-53), and selectively transmits light in a corresponding wavelength band near a characteristic wavelength; and a first trim filter (70, 210), which is located between the light source and the photodetectors (51-53), and includes a material layer that selectively attenuates light of a first trim wavelength between two of the characteristic wavelengths.
