摘要： An image display apparatus according to an embodiment of the present technology includes an optical modulator, an optical device, and a sensor unit. The optical device splits a modulated light beam modulated by the optical modulator into a first split light beam and a second split light beam, the first split light beam and the second split light beam each travelling in a different direction, and prevents a light beam, which backwardly travels on an optical path of the first split light beam and enters the optical device, from travelling along an optical path of the second split light beam. The sensor unit is disposed on the optical path of the second split light beam and detects a state of the second split light beam.

摘要： An improvement in quality is achieved by improving a contrast ratio. Therefore, in a projector device including a light source device using a solid-state light source (AR) includes a temperature adjustment device (190) capable of setting a state in which a temperature of at least the solid-state light source is caused to increase. Then, a determination unit (12) determines a luminance state of an image and a control unit (16) controls a heat state of the solid-state light source (AR) by controlling the temperature adjustment device (190) on the basis of a determination result. In particular, by increasing the temperature of the solid-state light source (AR) in accordance with an image, light emission efficiency is lowered to decrease luminance.

摘要： An image display apparatus according to an embodiment of the present technology includes a polarizer, a polarization conversion element, and a ¼ wave plate. The polarizer causes to transmit linearly polarized light having a predetermined polarization direction. The polarization conversion element converts a polarization state of the linearly polarized light transmitted through the polarizer and emits the light as light in a non-polarized state. The ¼ wave plate is arranged on an optical path of the light in the non-polarized state emitted from the polarization conversion element.
