| 发明名称 | Projector and control method for projector | ||
| 摘要 | A projector which modulates light emitted from a light source and projects the light, the projector including: an image acquiring unit for acquiring an image from an image source; a modulating unit for modulating the light emitted from the light sources, based on the image acquired by the image acquiring unit; a light adjustment mechanism for reducing an amount of light incident on the modulating unit from the light source; and a light adjustment control unit for performing light adjustment control by the light adjustment mechanism, based on the image acquired by the image acquiring unit; wherein the light adjustment control unit stops execution of the light adjustment control when at least one of an operating state of the projector and a state of the image acquired by the image acquiring unit meets a predetermined condition. | ||

| 主权项 | 1. A projector which modulates light emitted from a light source and projects the light, the projector comprising: an image acquiring unit for acquiring an image from an image source; a modulating unit for modulating the light emitted from the light sources, based on the image acquired by the image acquiring unit; a light adjustment mechanism for reducing an amount of light incident on the modulating unit from the light source; and a light adjustment control unit for performing light adjustment control by the light adjustment mechanism, based on the image acquired by the image acquiring unit; wherein the light adjustment control unit stops execution of the light adjustment control when at least one of an operating state of the projector and a state of the image acquired by the image acquiring unit meets a predetermined condition, andthe light adjustment control unit performs control to lower a light reduction level by the light adjustment mechanism when the light adjustment mechanism maintains a predetermined light-adjusted state. | ||
