More Information
Summary:A detector array method and apparatus for real time in-situ color control in printers and copiers (Fig. 1) includes an array (104) for performing a linear matrix transformation on color patch information generated by a printer or copier. A light sensor array (102) detects color components from a series of color test patches (142; Fig. 3) and performs a predetermined matrix transformation on the color information to produce a set of control signals for feedback to the printer or copier. In another embodiment (Figs 7, 8), the light sensor array is extended to produce a fully analog neural network processor which is capable of arbitrary mappings of the color information into control signals for use by the printer or copier apparatus. The system is fully programmable, adaptive and, in one embodiment, trainable using backpropagation or other techniques.
