ABSTRACT:
This invention has as its object to provide an image processing apparatus and method, which can obtain high image quality by adjusting an image forming parameter or parameters in consideration of a variation in image forming condition. In order to achieve the object, the gradation characteristics of an image to be recorded are adjusted on the basis of information obtained by forming a gradation characteristic adjustment test pattern on a recording medium, and reading the formed test pattern. Subsequently, the color reproduction characteristics of an image to be recorded are adjusted on the basis of information obtained by forming a color reproduction characteristic adjustment test pattern on a recording medium, and reading the formed test pattern.
