IEC 61966-3 pdf download Multimedia systems and equipment – Colour measurement and management – Part 3: Equipment using cathode ray tubes
This part of lEC 61966 deals with equipment using cathode ray tubes (CRT) to display colourimages for use in multimedia applications.
A series of methods and parameters for colour measurements and management for use inmultimedia systems and equipment is applicable to the assessment of colour reproduction.Themethods of measurement standardized in this part are designed to make possible the objectiveperformance assessment and characterization of colour reproduction of CRT displays whichaccept red – green – blue analogue or digital signals from electrical input terminals and outputcolour images on CRT display screens.For CRT displays to which analogue signals areapplicable,corresponding digital signals shall be taken into account in applying this part ofIEC 61966. The measured results are intended to be used for the purpose of colourmanagement in multimedia systems.
This part of lEC 61966 defines input test signals，measurement conditions and methods ofmeasurement, so as to make possible the colour management and comprehensive comparisonof the results of measurements.
Colour control within equipment is outside the scope of this part of lEC 61966. lt does notspecify limiting values for various parameters.
