  • Patent number: 6313823
    Abstract: A system measures the color output of a computer monitor by using predetermined phosphor characteristics of the monitor that are stored in monitor memory. The relationship between beam current and pixel values is then determined and stored in computer memory. When a color output measurement is taken, the average pixel values are determined. The beam currents associated with the average pixel values are then accessed from the computer memory and multiplied by the phosphor characteristics to obtain an accurate color output measurement.
