A light source apparatus, includes a first solid-state light source and processing circuitry. The first solid-state light source is configured to output first light. The processing circuitry is configured to control a power source to supply first current to the first solid-state light source, determine whether to change the supply of the first current to the first solid-state light source to maintain a brightness level of the first light output by the first solid-state light source at a first brightness level or within a first brightness level range, and control the power source to change the supply of the first current to the first solid-state light source to output the first light at the first brightness level or within the first brightness level range in response to a determination that the supply of the first current is determined to be changed.

Light source apparatus, projection type display device and light source control method

A projection display apparatus according to an embodiment of the disclosure includes: a projection unit including a light source section, a wavelength converter including a discoid member and a motor section, the discoid member including a wavelength conversion layer that converts outgoing light from the light source section to light having a wavelength range different from that of the outgoing light, and the motor section rotating the discoid member, and a spatial modulation element that generates image light by modulating light from the light source section and the wavelength converter on the basis of an inputted image signal; and a control unit that controls intensity of the outgoing light emitted from the light source section and a number of rotation of the discoid member in a state where the image light is generated by the spatial modulation element.

Projection display apparatus and method of controlling projection display apparatus

There is provided an image display apparatus including: a light source unit; at least one light modulation device configured to modulate light from the light source unit, and to emit a modulated light beam; and a sensor configured to receive diffracted light of the modulated light beam emitted from the at least one light modulation device, and to measure intensity of the modulated light.

Image display apparatus and control method

A projection type image display device () including a light source (), an illumination optical system () which uniformly radiates light flux emitted from the light source () onto a surface (SCR) of an image modulation element which becomes a primary image surface, a projection optical system, capable of being set at a distance very close to a focal distance of a projection image, which magnifies and projects image information of the primary image surface modulated by the image modulation element onto a projection surface which becomes a secondary image surface, and a corner focus control section capable of automatically adjusting a focal distance of at least corner regions of the projection image to a focal distance corresponding to a projection distance of the projection image.
