Abstract

Official abstract text for this publication.

A projector includes a light source, a light source control section adapted to control a luminance of light emitted from the light source, an acquisition section adapted to obtain an image signal, a projection section adapted to project image light obtained by modulating the light emitted from the light source based on the image signal obtained by the acquisition section, and the correction section adapted to correct the image signal, when the luminance of the light emitted from the light source changes under control of the light source control section, so that a variation in an output luminance of the image light projected by the projection section is increased to a level greater than the variation in the luminance of the light emitted by the light source.

First claim

Opening claim text (preview).

What is claimed is: 1. A projector comprising: a light source; a light source control section adapted to control a luminance of light emitted from the light source; an acquisition section adapted to obtain an image signal; a projection section adapted to project image light obtained by modulating the light emitted from the light source based on the image signal obtained by the acquisition section; and a correction section adapted to correct the image signal, when the lumin…
