A device and method are disclosed for capturing an electronic image signal from the interaction of light with features of, on, or near a media surface. In addition to signature marks, these features can include characters, character strings, symbols, icons, dot pitches, line types, line and character formats, optical densities, color, indentations, texture, and patterns. More specifically, the claimed invention is useful primarily for optically capturing, processing, parameterizing, and identifying hand written signatures, but may also be applied to identification of other surface features such as print, line art, graphics embossments, textures or colors. The signals are captured, processed, sometimes parameterized, and used to make associations with an identifying name. These associations can be given a statistical probability of correctness.
