Image projection apparatus for adjusting white balance in consideration of level of light emitted from LED and method thereof

Abstract

An image projection apparatus which adjusts a white balance in consideration of levels of light emitted from light-emitting diodes and a white balance adjustment method thereof. The image projection apparatus comprises a light source unit for sequentially emitting lights generated by a red (R)-light emitting element, a green (G)-light emitting element, and a blue (B)-light emitting element. An image generation unit generates an image using the lights sequentially emitted from the light source unit and projecting the image. A driving unit drives the light source unit and the image generation unit. A light sensor measures levels of lights generated by the R-light emitting element, the G-light emitting element, and the B-light emitting element. A controller controls a driving operation of the driving unit based on the levels of lights measured by the light sensor to adjust a white balance of the image projected from the image generation unit.
