ABSTRACT:
A color marking device including a control system for calibration of the device based upon dynamic color balance control of an output image. The system comprises a front end converter for converting an input signal representative of a target image comprising a preselected color into a device-dependent control signal in accordance with a device TRC, a color marking device for outputting an output image in response to the control signal, a sensor for measuring a parameter from the output image representative of a color of the output image, and, a point-wise controller for comparing the parameter with a corresponding parameter from the target image and constructing adjusted controlled points for the device TRC when the measured parameter and the corresponding parameter vary by a preselected value, a color balance controller for constructing an adjusted device TRC from the controlled points, whereby subsequently generated output images are output with the adjusted device TRC and, more accurately represent target input images.
