发明名称 APPARATUS AND METHOD FOR PERFORMING EXPOSURE ON PHOTORECEPTOR DRUM
摘要 In a case where a determination is made that a density of a pixel of interest is greater than a threshold, or in a case where a pixel having a greater density than the threshold is present in a neighborhood of the pixel of interest at a predetermined distance from the pixel of interest, exposure with intensity corresponding to a density of the pixel of interest to which a predetermined density has not been added is performed on a photoreceptor drum at a position corresponding to the pixel of interest. Otherwise, exposure with intensity corresponding to a density of the pixel of interest to which the predetermined density has been added is performed on the photoreceptor drum at the position corresponding to the pixel of interest.

主权项 1. An apparatus comprising: a determination unit configured to determine whether a density of each pixel in image data is equal to or less than a threshold; and an adding unit configured to add a predetermined density to a density of each pixel, wherein, in a case where a determination is made that a density of a pixel of interest is greater than the threshold, or in a case where a pixel having a greater density than the threshold is present in a neighborhood of the pixel of interest at a predetermined distance from the pixel of interest, exposure with intensity corresponding to a density of the pixel of interest to which the predetermined density has not been added is performed on a photoreceptor drum at a position corresponding to the pixel of interest, otherwise, exposure with intensity corresponding to a density of the pixel of interest to which the predetermined density has been added is performed on the photoreceptor drum at the position corresponding to the pixel of interest.
