  • Color balanced camera with a flash light unit
    Patent number: 7570881
    Abstract: The imaging device comprises a flash light unit, an imaging unit, a memory comprising predetermined color balance parameters specific to the individual flash light unit, and an image processor to correct the image colors based on the parameters. The predetermined parameters are determined by imaging a white test target and stored into memory. The predetermined parameters are applied at a later stage for the color correction of actual images. Consistent image colors may be guaranteed in mass production of the imaging devices although the individual flash light units may have different spectral properties.
