    Abstract: An illumination optical system for a beam projector includes: a light source; a color conversion unit having at least one fluorescent substance layer that reflects a light from the light source or converts the light emitted from the light source to a wavelength-converted light; and a dichroic mirror that causes the light emitted from the light source to be incident on the color conversion unit. Lights reflected or emitted by the conversion unit and having different wavelengths are incident on a display panel through the same path. In the illumination optical system, a light emitted from one light source can be processed to produce red, green and blue lights which can be in turn incident on the display panel through the same optical path of the light reflected or emitted by the conversion unit.

    Abstract: A portable projector includes a projector module for projecting image data, an infrared ray output unit which outputs an infrared ray to a projected image data area, a camera unit which photographs the projected image data area, a coordinate value calculator which calculates a coordinate value corresponding to each coordinate value of the photographed projected image data area, and a controller which determines whether there is a pen or a finger input in the projected image data area according to the calculated coordinate value and performing a control for updating the image data by using an input coordinate value corresponding to the input when there is input by the one of the pen and the finger.
