Abstract
The present invention is directed to a density processing method in which input gray level-output gray level data are previously generated and stored a first storing device, the input gray level-output gray level data are transferred to a second storing device, and an address in the second storing device is designated on the basis of input gray level data inputted so that output gray level data stored in the specified address in the second storing device is outputted. In the present invention, access addresses to the second storing device are converted depending on the designated copy density, so that input gray level-output gray level characteristics are converted into characteristics corresponding to the designated copy density.
