摘要:
A method for processing black point compensation parameters for a color image to be printed so as to enhance image quality of the color image is provided. The method includes analyzing image content of a received color image to identify one or more performance attributes to be considered during a black point compensation parameters processing procedure, the performance attributes estimate an effect of the black point compensation parameters on the image quality of the received color image; selecting, based on the identified performance attributes, a black point compensation (BPC) algorithm to be used during the processing procedure; deriving a model using the identified performance attribute that is configured to estimate relationships between the black point compensation parameters and the identified performance attribute; maximizing the performance attribute of the derived model so as to process the BPC parameters for the color image; and using the processed black point compensation parameters to construct output device profiles.
