Abstract
Abstract A color image forming apparatus having inputting means for inputting conditions of factors (lighting condition, region, color of eyes, season and date) determining the impression of a color image on an observer. The apparatus further has adjusting means for adjusting at least one of parameters (shading correction data, a reflectance-density conversion characteristic, a UCR/BP characteristic, a masking coefficient, color balance data and γ correction data) of an image processing unit to the input conditions.
