COLOR LUMINANCE CORRECTION APPARATUS, PROJECTOR PROVIDED WITH COLOR LUMINANCE CORRECTION APPARATUS, AND COLOR LUMINANCE CORRECTION METHOD

摘要

PPROBLEM TO BE SOLVED: To provide a color luminance correction apparatus capable of realizing color luminance correction in accordance with a luminance change in a reflected light of all projected image lights, and to provide a projector. PSOLUTION: The color luminance correction apparatus 20 includes: a first memory 2 that stores reflection luminance information of a reflected light of each color respectively detected by photoelectric conversion elements having four color (red, green, blue, yellow) filters and receiving the reflected light 17 from a projection screen 30; a second memory 26 for storing in advance reference luminance information of the predetermined reflected light by each color; a color luminance correction data generating section 27 for comparing the reflection luminance information with the reference luminance information to generate color luminance correction data; and a color luminance correction circuit section 28 for correcting an image signal received by the projection unit 10 on the basis of the color luminance correction data, and the projector 1 sequentially projects image lights in four colors or more formed by an image forming section 14 to the projection screen 30 to display a color image.
