| 发明名称 | Projector and light emission control method in projector | ||
| 摘要 | 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. | ||

| 主权项 | 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, the adjustment values being a light amount ratio among RGB components of the modulated light modulated by the modulator; 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. | ||
