Abstract

In this paper, we present a set of methodologies for Digital Cinema projector calibration, quality verification and evaluation by application of the international visual test SMPTE Digital Projection Verifier (DProve) as well as related SMPTE and ISO standards. We demonstrate modified SMPTE guidelines for faster, simpler and more precise measurements in practical conditions and introduce several tools for illustrative quality evaluation. The measurement interpretation is based on both, absolute tolerances defined by the SMPTE standards, as well as relative assessment calculated by the CIEDE2000 color difference formula. The latter approach is intended to better understand the importance of the color and tonality error for viewer's perception in the specific cinema low light levels. On the examples of selected D-Cinema projector and display measurements, we introduce possible strengths and weaknesses of various projection technologies, used in Czech and Slovak commercial cinema or review rooms, which differs by the specific manufacturer's technology or type of light source.
