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.

Liquid-crystal projector
A liquid-crystal projector includes: liquid-crystal panel sections a first illumination section including a red light source, red light emitted from the red light source being applied to a liquid-crystal panel section; a second illumination section including a green light source, a blue light source and a polarizing beam splitter that splits green light emitted from the green light source into p-polarized light and s-polarized light, the green s-polarized light being applied to a liquid-crystal panel section, the green p-polarized light and blue light being applied to a liquid-crystal panel section on the same optical path; a cross dichroic minor that combines images displayed on liquid-crystal panel sections; a projection lens that projects the combined image; and a control unit that controls on/off states of the red light source, the green light source and the blue light source based on an input video signal to display respective images on the liquid-crystal panel sections.. .

Three-dimensional shape measuring apparatus and control method thereof
An exposure amount of at least one or more first patterns used to determine positions at the time of triangulation is set to be larger than that of other patterns, so as to reduce the influence of shot noise in the first patterns, to improve precision, and to reduce power consumption as a whole. To this end, a three-dimensional shape measuring apparatus, which measures a three-dimensional shape of an object to be measured by projecting pattern light of a plurality of types of patterns onto the object to be measured, and capturing images of the object to be measured, controls a projector unit and image capture unit to set an exposure amount of the first patterns to be larger than that of patterns other than the first patterns..

Display device, and method of controlling display device
A projector includes a projection unit adapted to display an image based on image data supplied from a pc or an image processing unit as an image supply section, a position detection unit adapted to detect an operation by a pointing body, a coordinate conversion section or an output section adapted to output the pointed position to the image supply section in the case in which the operation is detected by the position detection unit, and an operation determination section adapted to restrict the output of the pointed position in the case in which the operation detected by the position detection unit is an operation satisfying a condition set in advance.. .
