<p>The purpose of the present invention is to provide a projector that has a simple structure and that corrects trapezoidal distortion of a projection screen while correcting unevenness in color by using a processing unit that performs OSD processing. This projector includes a memory that stores OSD data and color-unevenness correction data for correcting unevenness in color, and a processing unit that performs OSD processing in which the OSD data is combined with a video signal, wherein: when a trapezoidal-distortion correcting unit receives a trapezoidal-distortion correction parameter, the trapezoidal-distortion correcting unit corrects the color-unevenness correction data in accordance with the trapezoidal-distortion correction parameter and records the corrected data in the memory as color-unevenness correction data for distortion correction; and when the processing unit receives a video signal, the processing unit combines said correction data for distortion correction with the video signal, and the trapezoidal-distortion correcting unit subjects this video signal to trapezoidal-distortion correction by using the trapezoidal-distortion correction parameter.</p> |
