One image forming/capture device feature is the ability to finely control image quality response curves. To enable fine control, the user defines a number of points to which the response curve is to be fit. The response curve is fit to or through these points. However, users have trouble appreciating the effects of this adjusted response curve in converting input image values to output image values. The response curve control graphical user interface allows the user to finely control a response curve of an image quality for an image forming/capture device in an intuitive manner, by providing a plurality of slider portions that allow the user to more intuitively control the image quality response curve. These slider portions mimic control elements of conventional photocopier control panels. Each slider corresponds to a point, or a range of points, of the response curve. The slider portions are arranged so that the points associated with each slider portion are arranged in an easily understandable order. Each slider portion indicates, for the associated point, or range of points, of the input image, the image value of the output image for that point, or for that range of points. The appearance of a portion of each of the slider portions is altered based on the selected image value of the output image for the point, or the range of points, of the input image. Thus, the user can intuitively appreciate the effects of adjustments made to the response curve.
