The factor effect on CIE coordinates error is analyzed, system error caused by standard source transfer is argued and the background signal subtraction method is brought forward. The repeatability error caused by random noise is also analyzed.

• 对影响色坐标的各项因素进行了误差分析,分析了标准传递带来的系统误差和基线扣除方法,分析了随机噪声带来的重复性误差。
