摘要： The present invention further improves gradation characteristics from a highlight region to a high-density region. First, the correction processing receives image data, and an image attribute discrimination discriminates whether the data are related to a character/thin line or others on the basis of attribute information on a pixel of interest. If it is discriminated that the data are related to a character/thin line, a pattern matching to data stored in a line buffer is performed to obtain a pixel distance, and in accordance with the pixel distance, a correction amount is determined on the basis of an LUT set in a correction amount determination. Subsequently, on the basis of the determined correction amount, corrected image data are generated and output to the following step.

摘要： Good images are formed without density irregularity even if an image supporting body varies with time. Potentials at developing locations after exposing the surface of an a-Si photoconductive body, which are recorded in a potential attenuation characteristic map, are compared with seven ranges A-G obtained by dividing the surface of the a-Si photoconductive body at every 6-volt interval to detect deviations of the potentials from a prescribed potential Vl (step S2). Individual blocks all over the surface of the a-Si photoconductive body are classified to A-G, and the exposure values are set in accordance with A-G so that Vl of the individual blocks on the surface of the a-Si photoconductive body belongs to D range (step S3). An input image undergoes image processing after its entire plane being divided into blocks corresponding to the surface of the photoconductive body (steps S4 and S5).
