Exposure apparatus for controlling the duration of exposure operations according to compensated exposure data

An exposure apparatus responsive to exposure data for controlling a duration of an exposure operation performed by an exposure device to reproduce gradations on a photosensitive material, comprising:

• a converter means for converting the exposure data into compensated exposure data in which the duration of the exposure operation is compensated according to predetermined characteristics, said converter means comprising:
• a conversion table containing the compensated exposure data, wherein the exposure data corresponds to the compensated exposure data, respectively, in said conversion table;
• a conversion data setting means for setting the compensated exposure data in said conversion table according to the predetermined characteristics;
• and
• a reference means for selecting the compensated exposure data from said conversion table in accordance with the exposure data;
• and
• an exposure controller means for controlling the duration of the exposure operation of the exposure device according to the compensated exposure data selected by said reference means.
