Abstract
In a method for automatic color wheel calibration in a projector, the color wheel includes three primary colors and a non-primary color. The method includes: enabling the projector to project the non-primary color, and measuring first optical physical amounts of the projected non-primary color; enabling the projector to project a combination color of the three primary colors having respective color level values, measuring second optical physical amounts of the projected combination color, and adjusting the respective color level values of the three primary colors according to respective values of differences between the first optical physical amounts and the second optical physical amounts; and repeating the above steps until each of the values of differences approximates zero, thereby obtaining color level values for the three primary colors to produce a combination color matching the non-primary color.
