Scope projector / projector

Current projector should be turned on the screen after purchasing the separate while screen. So, there happens spatial constraint. Although projector gets more mobility as it becomes smaller, its mobility is gated by the bigger screen since screen size gets bigger. So, I propose you the projector which can be used in any walls without separate screen. ddd project has a separate camera lens, it shoots beam per trichromatic principle by recognizing the condition of wall. therefor, it makes the perfect screen by recognizing the pattern although there's any pattern of colors in the wall.
