摘要： This invention provides a method of operating a projection system wherein light emitted from a high-pressure discharge lamp being lit with d.c. lamp current is passed through color segments of a color filter sequentially and then reflected by an optical element to project an image on a screen, the color segments of the color filter including red, green and blue color segments and a color segment comprising a green ND filter having a relatively low lightness. The method includes making lower a crest value of the d.c. lamp current fed to the high-pressure discharge lamp for a first illumination period during which the color segment comprising the green ND filter is illuminated than a crest value of the d.c. lamp current fed to the high-pressure discharge lamp for a second illumination period during which any one of the other color segments is illuminated, in synchronism with the first illumination period.

A pick-up (11) of an optical information recording/reproducing apparatus generates information light by spatially modulating laser light emitted from a light source unit (20) with a spatial light modulator (22), and generates recording-specific reference light spatially modulated in phase by spatially modulating the phase of the laser light emitted from the light source (20) with a phase-spatial light modulator (16). The information recording layer (3) of the optical information recording medium (1) is irradiated with the information light and the recording-specific reference light. An electromagnetic coil (30) applies a magnetic field to the information recording layer (3). A three-dimensional distribution pattern of magnetization corresponding to the interference pattern resulting from the information light and the recording-specific reference light is formed in the information recording layer (3).
