| 20110310436 | IMAGE QUANTIZATION FOR DIGITAL PRINTING - An image may be quantized into a pattern of dots, e.g., for devices capable of printing dots of variable size and variable color intensity. One may use a pre-determined mapping of the continuous-tone intensity value into a discrete vector of intensity values, and each intensity value may then be processed by a set of binary quantizers. The resulting binary vector may then be mapped into a combination of available dot sizes and color intensities. Through a scalar multiplier, the pre-determined mapping of continuous-tone intensity values may be used as multiple print resolutions. | 12-22-2011 |
