NOVELTY - The reader (100) has a color filter array (114) placed in a housing (102) relative to a global shutter sensor (112) to filter incoming electromagnetic energy (118). The color filter array includes a portion (116) e.g. aggregate portion, that passes the incoming electromagnetic energy of wavelengths in a portion of an electromagnetic spectrum to a portion of the global shutter sensor. The portion of the color filter array limits passage of the incoming electromagnetic energy of the wavelengths outside of the portion of the electromagnetic spectrum to the global shutter sensor.    USE - Portable reader e.g. battery powered or rechargeable handheld reader and line powered stationary system reader such as self service kiosk and sales terminal, for reading a two-dimensional visible infrared, blue or black colored machine-readable symbol rendered using inks and toners on a substrate in post offices and retail environments and on railcars, automotive parts, driver's licenses, advertisements, shipping labels and letter or parcel packages. Uses include but are not limited to image, mark, sign and insignia rendered using inks and toners on a paper substrate, polymeric plastic substrate and cloth substrate.    ADVANTAGE - The reader can quickly and easily adapt the multitude of machine-readable symbol styles and symbologies. The reader improves overall package and letter handling productivity as time is not spent switching from the reader for a first symbol type to another reader for a second symbol type. The reader allows the post offices to use specialized media such as inks, that fluoresce when exposed to a specific wavelength of the electromagnetic energy so as to increase security and reduce incidence of postal fraud.    DETAILED DESCRIPTION - The portion of the electromagnetic spectrum is a blue portion, UV portion, red portion or an infrared portion. INDEPENDENT CLAIMS are also included for the following:    (1) an image detection method    (2) an image detection system.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic block diagram of a machine-readable symbol reader system in use with a substrate bearing a machine-readable symbol.
