Abstract

A method of an operation of a projector, projector including first, second, and third light provider configured to output a first, second, and third light having first color, first generator configured to generate first output light from first light, second generator configured to generate second output light from second light, third generator configured to generate third output light from third light, and projection optical system configured to project projection image using first, second, and third output light, method includes, based on image information representing first image, amplification information representing degree of amplification of brightness of first image, and controlling, based on amplification information, proportion of light intensity of second output light to light intensity of second light received by second generator, and proportion of light intensity of third output light to light intensity of third light received by third generator.

A method of an operation of a projector,

the projector including
a first light provider configured to output first light having a first color,
a second light provider configured to output second light having a second color,
a third light provider configured to output third light having a third color,
a first generator configured to generate first output light from the first light,
a second generator configured to generate second output light from the second light,
a third generator configured to generate third output light from the third light, and
a projection optical system configured to project a projection image using the first output light, the second output light, and the third output light,
the method comprising:
determining, based on image information representing a first image, amplification information representing a degree of amplification of brightness in the first image;
and
controlling, based on the amplification information,
a proportion of light intensity of the second output light to light intensity of the second light received by the second generator, and
a proportion of light intensity of the third output light to light intensity of the third light received by the third generator.
