Abstract
Routine color calibration is imperative for medical applications that rely on color fidelity such as digital pathology, endoscopy, and colposcopy. However, commercially available products vary greatly in price and performance with no available evaluation standard. Related studies have used only one or a few displays to evaluate the performance of color calibration kits. We propose the concept of Virtual Display, a universal display platform that emulates the colorimetric response of real displays. A wide-color-gamut display driven by an FPGA is used to emulate the colorimetric response of real display devices. By changing the look-up tables in the FPGA, the virtual display emulates various real displays for testing different color calibration kits. Our experimental data for 6 real displays show that the virtual display can emulate real displays reasonably well. The results demonstrate that the proposed virtual display approach is a fast, economical, and objective method for evaluating the performance of color calibration kits.
