    摘要: Disclosed is a sharpness improvement apparatus of an image signal which improves a sharpness of an analogue image signal so as to display a clear image. A display device which displays an inputted image signal on a screen can display a clear image with a digital sharpness improvement apparatus which realizes a sharpness of the image signal into a digital method by improving a degradation phenomenon of a signal generated at an analogue image processing into a simple digital circuit.

    摘要: A projection display device (100) capable of providing a virtual keyboard function to the user, using a light source of a pico projector, is discussed. According to an embodiment, the projection display device includes a light source unit (110) configured to emit lights; a light combining unit (120) configured to generate a leakage light from the lights emitted by the light source (110) unit and to selectively combine the lights from the light source unit (110); an image projection unit (130) configured to project an image using the combined light from the light combining unit (120); and a virtual input unit (140) configured to project an input unit image (150) using the leakage light from the light combining unit (120).
