AbolishedTest charts of reflection for television--Registration test chart A
反射式电视测试图 重合测试图 A 型
Application Summary AI generated
This standard specifies the design and application of a registration test chart (Type A) for evaluating the geometric alignment and color convergence of reflection-type television cameras and imaging systems. It is used in the production, calibration, and quality testing of television equipment, particularly in broadcasting and professional video environments, to ensure accurate image registration across red, green, and blue channels. The chart is applied as a reference target under controlled lighting conditions to assess and adjust system performance.
