摘要:
A multimedia player for providing two projection images is provided. The multimedia player for displaying two projection images includes: a first projection unit displaying a first projection image; and a second projection unit displaying a second projection image. The first projection unit includes: a first driving unit controlling an operation of the first projection unit and providing an image signal on the first projection image to be displayed; a first light source unit; a first light modulation device outputting the first projection image by modulating light provided from the light source in response to the image signal of the first projection image; and a first projection lens unit magnifying and projecting an image that is output from the first light modulation device. The structure of the first projection unit is the same as that of the second projection unit. The multimedia player further includes a screen sensing unit sensing a color of an area in which an image is to be displayed. The first and second driving units detect a complementary color of a color sensed by the screen sensing unit and increase brightness of a light source corresponding to the complementary color among light sources of the first and second light source units or image data corresponding to the complementary color among image data to be displayed, thereby improving visibility.
