由于可能在计算机控制的彩色监视器上显示大量的刺激配置，因此不可能直接测量帧缓冲区的数字输入值与监视器输出值之间的关系。为了校准监视器，有必要对监视器的性能做出假设。这些假设允许根据输入值和可行数量的校准测量的结果来预测监视器对任何一组输入值的输出。本文描述了一组足以使监视器校准问题易于处理的假设。这些是荧光粉常数假设、荧光粉独立性假设、空间独立性假设和单一尺度因子假设。如果这些假设成立，监视器可以通过测量荧光粉光谱功率分布、测量荧光粉输入输出关系和测量许多位置的空间尺度因子来校准。违反这些假设限制了校准的准确性。本文给出了Barco 5351显示器的测量结果，测试了这些假设的有效性。
Because of the large number of stimulus configurations that may be displayed on a computer controlled color monitor, direct measurement of the relation between the digital input values to the frame buffer and the output of the monitor is not possible. To calibrate a monitor, it is necessary to make assumptions about the monitor's performance. These assumptions allow the monitor's output for any set of input values to be predicted from the input values and the results of a feasible number of calibration measurements. This article describes a set of assumptions that are sufficient to render the problem of monitor calibration tractable. These are the assumptions of phosphor constancy, phosphor independence, spatial independence, and the single scale factor assumption. If these assumptions hold, a monitor may be calibrated by measurements of the phosphor spectral power distributions, measurements of the phosphor input‐output relations, and measurements of the spatial scale factor at a number of locations. Violations of these assumptions limit the accuracy of calibration. The results of measurements that test the validity of these assumptions for a Barco 5351 monitor are presented.
