Method and System for Accurate Measurement of Color Performance of Electronic Displays Using Low-Accuracy Measurement Devices

摘要

In a calibration method, high-accuracy reference values obtained using a high-accuracy optical sensor are received, low-accuracy reference values are determined from reference colors captured from a display using a low-accuracy optical sensor having a lower accuracy than the high-accuracy optical sensor, color measurement values are determined from one or more colors captured from the display using the low-accuracy optical sensor, and the color measurements values are adjusted based on one or more color conversion equations to obtain adjusted color measurement values. The one or more color conversion equations are based on the high-accuracy measurement values and the low-accuracy measurement values. The high-accuracy reference values are reused for calibrations of one or more other low-accuracy optical sensors.
