A system is described that uses [device&#x3e;PCS] transformations for a source and destination device along with user preference information to create a composite [device&#x3e;device] transformation which is used to convert a color in a source space from a source device into a color in a destination space provided to a destination device. The user preference information can be a default or extracted from an image or from the profiles involved or from a GUI. The system modifies the domain of the [device&#x3e;PCS] transform from a destination device profile through the use of an ink manifold such that there are three input dimensions. The inking manifold can be an identity transform. The system also modifies the range of the [device&#x3e;PCS] transform from a source device profile such that the PCS coordinates are all within the range of the modified [device&#x3e;PCS] transform. The modified destination transform is inverted for values in the source transform domain to produce the [device&#x3e;device] transform. The range of the [device&#x3e;device] transform can be modified by applying the inking manifold transform to yield coordinates in the range of the destination device.

The apparatus and method of the present invention quickly determines the presence of contours in a digital color image by determining the busy and the non-busy (smooth) regions of the original digital color image and determining the luminance variations in the smooth regions of the original digital color image and in a quantized version of the original digital color image. The difference between the luminance variations is compared against a selected threshold value, which if exceeded causes a mark to be associated with the pixel under consideration. For each pixel of the quantized digital color image that is associated with the mark or has a mark associated with a neighboring pixel in a window around the pixel of interest the color of the pixel is selected to minimize and or remove the contour.

The present invention involves a computer-based expert system tool for making decisions regarding photofinishing processes. An expert mentor in the photofinishing area provides specific information both factual knowledge and judgmental knowledge including any judgmental rules he uses to make judgments and solve problems in the photofinishing area for a number of different processes. The expert then makes representative decisions using the computer which characterizes situations in terms of their data values based on information derived from a control strip used in the given photofinishing process. From this interaction the expert system tool of this invention is able to generate an internal representation of the logical processes of the expert and to characterize each situation in terms of a series of intermediate judgments. The expert system tool of this invention can determine the relative logical importance of each of the data points and to classify each as being of either major or minor significance.
