PROJECTOR, AND METHOD FOR CONTROLLING ROTATION OF PHOSPHOR WHEEL AND COLOR WHEEL IN PROJECTOR

摘要

In order to ensure uniform grayscale reproduction even when an error occurs in a phosphor wheel or a color wheel, the present invention controls the rotational movement of a phosphor wheel and a color wheel on the basis of color coordinate values for each grayscale measured at respective times when input timings of a first reference signal and a second reference signal input by the rotation of the phosphor wheel and the color wheel are changed multiple times while an image in which grayscales gradually change is displayed.
