#### C.32.3.4 Luminance Result Macro

This macro records the result of a Luminance QA task for a Display Subsystem.

Table C.32.3.4-1. Luminance Result Macro Attributes

Attribute Name | Tag | Description
--- | --- | ---
Number of Luminance Points | (0028,701B) | The number of luminance measurements recorded.
Luminance Response Sequence | (0028,701C) | Measured Luminance Response Values The number of Items shall match the value of Number of Luminance Points (0028,701B).
>DDL Value | (0028,7017) | The integer Digital Driving Level (DDL) at which this luminance value was measured. The DDL Value for the first item in the sequence shall be 0. The DDL Value of the last item in the sequence shall be the maximum DDL value. Two items in the sequence shall not have the same DDL value. The DDL Value of the items in the sequence shall increase monotonically.
>Luminance Value | (0028,701F) | Luminance in candelas per square meter (cd/m2) at the measurement location. ### Note Each measured luminance includes both ambient light and light from the display device.
>CIExy White Point | (0028,7018) | A single measured white point recorded for the display subsystem. The white point is recorded as a CIE xy chromaticity with two dimensionless floating point values where the first is the x value and the second is the y value.
Reflected Ambient Light | (2010,0160) | Reflected ambient light in candelas per square meter (cd/m2) when the measurements were taken.
Ambient Light Value Source | (0028,7025) | Source of the ambient light value. Enumerated Values: DEFAULT a configured default value was used. MEASURED the value was measured at the time of the other measurements. PROVIDED the value was provided by an external source.
