Introduction

Zhenhuan Wen, based in Pittsford, NY, has made significant contributions to the field of imaging technology through his extensive patent portfolio. With a remarkable total of 23 patents to his name, Wen has played a pivotal role in advancing methodologies that enhance the accuracy and efficiency of color calibration and image processing.

Latest Patents

Wen's latest inventions include a patent for "Scanner calibration using inverse matrix." This innovative technology involves methods and systems that calculate an initial matrix by correlating scanned test device-dependent values to device-independent color space values of a test sheet. The developed initial matrix facilitates the conversion of device-dependent values to device-independent color space values while accounting for any conversion errors. Wen’s methods derive an inverse matrix from this initial matrix, allowing for the calculation of target device-dependent values by applying the device-independent color space values to it. The finalized one-dimensional look-up tables isolate the conversion errors by correlating the scanned test device-dependent values to the device-independent color space values, ensuring accuracy in the final matrix specific to the scanner.

Another recent patent focuses on "Black trapping methods, apparatus, and systems for binary images." This invention enhances the processing of color image data by integrating a series of trapping condition logical operations, thus improving the quality of binary images.
