摘要
An optical engine for a projection apparatus, according to an embodiment of the present invention, comprises an image data input unit, an optical source, an image generator, a projector which projects an image produced by the image generator and light reflected from the image generator onto a screen, an iris unit which controls the quantity of light passing through the projector, and a controller that regulates the optical source, the image generator, and the iris unit based on image data input by the image data input unit. The quantity of light passing through the iris unit can be varied to improve the brightness of the image being projected onto the screen.
