Abstract

A method of calibrating a digital camera includes dispersing white light through a test device to generate a color dispersion image including a plurality of different wavelengths of light; capturing a test image of the color dispersion image; obtaining intensity values corresponding to at least two of the different wavelengths of light from the test image; and comparing the intensity values to expected intensity values. The test device may include a color dispersion medium, e.g., a variable band pass filter, and/or a light transmission medium. The method may further include obtaining at least two different values corresponding to an intensity pattern image containing a plurality of intensities of undispersed light transmitted through a light transmission medium.
