<p><P>PROBLEM TO BE SOLVED: To enhance image quality without making shading remain in energy distribution on a recording medium, even if the shading occurs in energy imparted to the recording medium, in a recording head which is equipped with two-dimensionally arranged recording elements. <P>SOLUTION: When one pixel is expressed by a plurality of dots, in addition to density correction based on a relative positional relationship with a peripheral pixel, data on the respective dots, which serve as final output data, are generated by means of thresholds different depending on a direction crossing a scanning direction, in accordance with information on the shading caused by an optical system and the like. Thus, an image faithful to inputted image data can be recorded. Particularly, when the recording head 162 is constituted by arranging a plurality of recording element units 166, periodical streak-like unevenness in density, which ranges in a direction orthogonal to the scanning direction, can be prevented from being caused by the shading. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
