A method of controlling a projector includes a distributing step of distributing each of luminance values of a plurality of pixels constituting an original image into a first luminance value, a second luminance value lower than the first luminance value, a third luminance value lower than the second luminance value, a first replacing step of replacing the luminance values of the pixels corresponding to the second luminance value with the third luminance value in the original image to generate a first image, a second replacing step of replacing the luminance values of the pixels corresponding to the second luminance value with the first luminance value in the original image to generate a second image, and a generating step of converting the luminance values of the pixels into transmittances in each of the first image and the second image to generate mask images.
