Abstract:
1. A projector comprising: 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 appropriate with the grayscales and the adjustment values stored in relation to each other; 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; and a controller that adjusts the light emission amounts of the light sources by using the light-emission-amount adjusting unit based on the adjustment values stored in the storage unit when the grayscales of the light sources are set at specific values, whereas adjusting the light emission amounts of the light sources by using the light emission-amount adjusting unit based on estimated values calculated from the adjustment values stored in the storage unit when the grayscales of the light sources are set at values different from the specific values.
