摘要： A method of controlling an image forming apparatus in accordance with the invention can include the steps of: providing a system tone reproduction curve; representing a manually adjustable tone reproduction curve; modifying the manually adjustable tone reproduction curve to be consistent with the system tone reproduction curve; and cascading the manually adjustable tone reproduction curve with the system tone reproduction curve to provide a new adjusted tone reproduction curve. The method in accordance with the invention enables a user to achieve enhanced flexibility in determining how to adjust an output image. The method can also determine a new system tone reproduction curve, based upon the current settings of the manually adjustable tone reproduction curve, in real time, which reduces the amount of storage space required.
