1. A color image analysis method comprising: emitting light from a light source towards a target material containing a plurality of components to cause fluorescence to be emitted from the target material; using the fluorescence omitted from the target material to form an image based on the plurality of components and obtain a formed image having color-phase values; using differences between the color-phase values to distinguish a first one of the components in the formed image from a second one of the components in the formed image; and producing a separate image of each of the first and second components using the differences in the color-phase values.
