Papers

Lumita and Lumita labs publish research and white papers on various subjects. We also produce papers and training materials for many of our clients. We are slowly aggregating that work here.

Achieving High Color Reproduction Accuracy in LCDs for Color-Critical Applications

Achieving High Color Reproduction Accuracy in LCDs for Color-Critical Applications A methodology and associated software modules for calibration, characterization and profiling of color LCDs for color-critical applications such as medical imaging is described. Supporting analyses reveal very high color reproduction accuracy as determined by CIE DE2000 color differences for 210 test colors uniformly distributed in CIE Lab color space.

Analysis of the proposed IEC “Color Light Output” digital projector specification metric, using CIELAB gamut volume.

“Color Light Output” is a proposed specification metric for IEC 61947-1 (Electronic projection – Measurement and documentation of key performance criteria – Part 1: Fixed resolution projectors) The study evaluates the performance of the color illuminance metric by testing a sample of popular digital projectors in the business and education category. The study confirms the utility of the color illuminance metric as a predictor of perceived color gamut and total projector performance.

Projector Contrast Ratio

Is Contrast Ratio of a Business Projector Important? Many projector manufacturers tout the contrast ratio of their projectors and make all kinds of claims about how high contrast ratios are better. In home theater, contrast ratio is an important metric. Does it make a difference in the classroom or boardroom?

Display Calibration Devices

Display Calibration Devices – Methods, Accuracy, and Cost. To calibrate and profile a display we need to take some measurements. When purchasing a solution for display calibration the measurement device itself is the most important factor. In this article we will examine what we need to measure and how to get the best measurements for a reasonable price.
