IEC 62629-12-2:2019 specifies the measuring methods of motion artifacts for stereoscopic displays using glasses. This document is applicable to stereoscopic displays using glasses, which consist of transmissive type active matrix liquid crystal display modules (without a post image processing).

Abstract

Overview

IEC 62629-12-2:2019 is an international standard published by the International Electrotechnical Commission (IEC) that specifies the measuring methods for motion blur artifacts in stereoscopic 3D displays using glasses. This standard applies particularly to stereoscopic displays made of transmissive type active matrix liquid crystal display (LCD) modules without post image processing enhancements.

Key Topics

Scope: The standard is focused on stereoscopic displays using glasses, specifically transmissive active matrix LCDs without additional image processing. It recognizes that some motion enhancement technologies may not be measurable through these methods.
Motion Blur Definitions:
- Motion Picture Response Curve: Represents the convolution of a display's temporal step response with a moving window of 1-frame width, simulating smooth pursuit eye tracking.
- Motion Induced Edge Profile: Luminance profile of a sharp moving transition when tracked smoothly by the eye.
- Edge Blur: Blur visible on a sharply defined luminance edge during movement, caused primarily by slow display response and hold-type characteristics.
Measurement Methods:
- Direct Measurement Method: Utilizes test patterns featuring sharp moving edges to directly measure motion blur using a pursuit camera system that simulates eye tracking. Includes standardized procedures for setup, edge detection, and analysis using metrics like Blur Edge Time (BET).
- Indirect Measurement Method: Measures temporal step responses from the display and derives motion blur characteristics mathematically. It involves dedicated measurement equipment and data processing techniques to obtain temporal luminance profiles and motion blur estimates.
Standard Measuring Conditions:
- Environmental parameters such as temperature, humidity, and ambient illumination are specified to ensure repeatability.
- Measurement methods include pivoting and linear pursuit camera systems to imitate the human eye’s motion tracking behavior.
Reporting:
- Detailed reporting format for test conditions, environmental parameters, measurement setups, and analysis results ensures transparency and comparability across different testing environments.

Applications

Display Performance Evaluation: Ensures stereoscopic 3D displays meet quality standards in motion rendering, crucial for 3D TVs, monitors, VR headsets, and 3D cinema screens.
Manufacturing Quality Control: Provides manufacturers with reproducible methods to test displays at production stages, minimizing variability in motion blur performance.
Research and Development: Supports engineers and scientists developing new stereoscopic display technologies by offering a reproducible framework to quantify motion blur artifacts.
Consumer Electronics Compliance: Facilitates conformance to international standards, improving interoperability and consumer trust in 3D display products.
