Abstract: A projector including: a plurality of light sources; a modulator that modulates light emitted from each of the plurality of light sources; a projection unit that projects the modulated light modulated by the modulator; a storage unit that stores grayscales of the light sources and adjustment values for adjusting the light emission amounts of the light sources in order to make white balance of the modulated light projected through the projection unit in relation to each other; and a light-emission-amount adjusting unit that adjusts the light emission amounts of the light sources based on the adjustment values corresponding to the grayscales of the light sources.

Abstract: A display apparatus includes a storage that stores a set period that is a period from the point of time when electric power supply starts to the point of time when a projection section starts displaying an image, a remote control that accepts operation, and a controller that changes the set period based on the operation accepted by the remote control, and the controller causes the projection section to start projecting the image after the electric power supply starts and the set period then elapses.
