发明名称 Method and system for optimizing black point compensation parameters
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 converting a received color image to a gray scale image; determining, using the received color image and the gray scale image, a performance attribute to estimate the effect of the black point compensation parameters on the image quality of the received color image, respectively; deriving a model to estimate relationships between the black point compensation parameters and the determined performance attribute; maximizing the performance attribute of the derived model so as to process the black point compensation parameters for the color image; and using the processed black point compensation parameters to construct output device profiles.

主权项 1. 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, the method is implemented in a computer system comprising one or more processors configured to execute one or more computer program modules, the method comprising: receiving the color image; determining, using the received color image, a performance attribute to estimate the effect of the black point compensation parameters on the image quality of the received color image, wherein the black point compensation parameters include a first tunable parameter and a second tunable parameter of a black point compensation algorithm, wherein the black point compensation algorithm is configured to map input color values for the received color image to an output data to be rendered by an output device, deriving a model to estimate relationships between the black point compensation parameters and the determined performance attribute; maximizing the determined performance attribute of the derived model so as to process the black point compensation parameters for the color image; and using the processed black point compensation parameters to construct output device profiles associated with the output device.
