Abstract: A projector is provided which can secure long-term reliability and enable high-speed start-up through suppression of local heat generation of phosphor. The projector includes a light source device including an excitation light source emitting excitation light, a phosphor disk on which a phosphor that converts the excitation light into fluorescence is continuously formed in a circumferential direction of the phosphor disk, a motor unit rotating the phosphor disk in the circumferential direction, a light modulation device generating an image light through modulation of light including the fluorescence, and a projection optical system projecting the image light. If the number of rotations of the phosphor disk reaches a predetermined number that is smaller than a target number, the excitation light source is turned on, while if the number of rotations of the phosphor disk is increased after reaching the predetermined number, an output of the excitation light source is increased.

Abstract: An electro-optical device includes a display unit that has a plurality of pixel portions constituting a display area on a substrate and an image signal processing. The image signal processing circuit generates an image signal that sets a first subframe frame luminance of the pixel portion in a first subframe and sets a second subframe luminance of the pixel portion in a second subframe. The first subframe and the second subframe are obtained by partitioning a first frame of a first frame image signal. The first frame has a frame luminance. The first subframe luminance is higher than the frame luminance and the second subframe luminance is lower than the frame luminance.

A liquid crystal panel is viewed via a blocking unit which blocks the field of view in a predetermined non-viewing period. A converting unit converts, based on a video signal, a gray-scale value input for each frame composed of a subfields into a subfield code indicating a combination of ON and OFF of b (2≦b≦a) subfields included in a viewing period other than the non-viewing period and c (1≦c≦b) subfields included in the non-viewing period. A driving unit drives a plurality of electro-optic elements each based on the converted subfield code.
