Image processing apparatus for performing image formation using signals obtained by pulse-width modulating an image signal by a plurality of modulating methods

An image processing apparatus comprising:

• (a) externally-inputting means for inputting into said image processing apparatus both image data and feature data representing a feature of the inputted image data, wherein both are outputted from an external apparatus;
• (b) discrimination means for discriminating a recording density change mode which is set from a plurality of kinds of recording density change modes;
• (c) generation means for determining a recording density for formation of an image of the inputted image data according to the recording density change mode discriminated by said discrimination means and the inputted feature data and generating control data indicating the determined recording density;
• and
• (d) externally-outputting means for outputting the control data generated by said generation means and the inputted image data to an external image forming apparatus.

An image processing method for an image processing apparatus comprising:

• (a) an externally-inputting step, of inputting into said image processing apparatus both image data and feature data representing a feature of the inputted image data, wherein both are outputted from an external apparatus;
• (b) a discrimination step, of discriminating a recording density change mode which is set from a plurality of kinds of recording density change modes;
• (c) a generation step, of determining a recording density for formation of an image of the inputted image data according to the recording density change mode discriminated in said discrimination step and the feature data and generating control data indicating the determined recording density;
• and
• (d) an image forming step, of forming an image according to the control data generated in said generation step and the inputted image data.
