A plasma lighting system comprises a resonator, a bulb received in the resonator and containing a discharge material therein for emitting light in accordance with the discharge material is exited as a plasma state, and a dielectric mirror disposed at one side of the bulb and formed of a spontaneous reflective material for spontaneously reflecting light generated from the bulb. The dielectric mirror can be included or excluded, and can smoothly reflect light without an additional reflection coating layer. The dielectric mirror is prevented from being damaged even in a high temperature, and thus a lowering of an optical efficiency is prevented when used for a long time.

Disclosed herein is an apparatus and method for balancing the color of a flashed image using depth estimation. The apparatus includes a depth value measurement unit, a region identification unit, a color impression estimation unit, and a color balancing unit. The depth value measurement unit measures the depth values of the respective regions of an image to be captured using a camera preview image. The region identification unit identifies the regions of the preview image as a region influenced by camera flash or a region not influenced by camera flash using the depth values measured by the depth value measurement unit. The color impression estimation unit estimates the color impression of actual illumination in the region not influenced by camera flash. The color balancing unit corrects the color of the region influenced by camera flash.
