Abstract
A shadow-added image formation device includes a photoelectric converting mechanism for converting every pixel into an electric signal, A/D-converting mechanism for A/D-converting an output of the photoelectric converting mechanism, a signal converting mechanism for converting an output of the A/D-converting mechanism into a binary serial signal representing white and black pixels, and a detecting mechanism for detecting an area to which shadow can be added from the output of the signal converting mechanism. A shadow signal formation mechanism for outputting a signal, a setting mechanism for setting a shadow area, an adding mechanism for comparing the widths of the areas detected by the detecting mechanism and set by the setting mechanism and adding the shadow signal to the binary serial signal corresponding to the smaller one of the areas determined by the comparison, and a reproducing mechanism for reproducing an image to which the shadow signal has been added, are also provided.
