Patent ID: 7088472

Claim:
An image forming system, comprising: an image input apparatus having an input property profile and configured to read an image from an image source and to convert said image into image data using said input property profile; an image processing apparatus configured to execute an image processing operation relative to said image data converted by said image input apparatus; and an image output apparatus having an output property profile and configured to output an image using said output property profile in accordance with said image data processed through said image processing operation executed by said image processing apparatus, wherein said image processing apparatus comprises: a property recognizer configured to read and recognize an input property profile of said image input apparatus and an output property profile of said image output apparatus; a memory configured to prestore a reference property profile; and a property calculator configured to calculate an optimal property based on said input property profile, said output property profile and said reference property profile, said image processing apparatus executing said image processing operation using said optimal property, wherein the image forming system further comprising a reference selector configured to receive said input and output property profiles from said property recognizer, and wherein said memory is configured to prestore a plurality of reference property profiles, said reference selector configured to select one of said plurality of reference property profiles prestored in said memory based on said input and output property profiles sent from said property recognizer, and said property calculator is configured to calculate said optimal property based on said input and output property profile and said selected reference property profile.
