Abstract
A projector and a method for projecting an image light beam according to an image signal are provided. The method includes: receiving the image signal; decoding the image signal to obtain a metadata of the image signal; converting a color space of the image signal from a wider color gamut to a narrower color gamut according to the metadata so as to generate a converted image signal; performing a gamma correction on the converted image signal according to the metadata to generate a corrected image signal; transferring the corrected image signal into an optical signal; providing a light beam; respectively modulating the light beam and a illumination beam according to the optical signal to form an image light beam; and projecting the image light beam.
