A projector modulates light emitted from a light source and projects the light, the projector including an image acquiring unit, a modulating unit, a light adjusting mechanism, and a light adjusting control unit. The image acquiring unit acquires an image from an image source. The modulating unit modulates the light emitted from the light sources, based on the image acquired by the image acquiring unit. The light adjustment mechanism reduces an amount of light incident on the modulating unit from the light source. The light adjustment control unit performs light adjustment control by the light adjustment mechanism, based on the image acquired by the image acquiring unit. The light adjustment control unit performs control to increase the amount of light incident of the modulating unit when the light adjustment mechanism maintains a predetermined light-adjusted state.

Projector and control method for projector

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.

A projector includes: a housing; an optical element accommodated in the housing; and an air supply unit configured to generate a flow of cooling air for cooling a cooling target element including the optical element, a dustproof area into which the cooling air can be introduced from the outside of the housing via a dustproof filter is formed inside the housing, the optical element is accommodated in the dustproof area of the housing, and the air supply unit includes a first air supply unit configured to introduce the cooling air from the outside of the housing to the dustproof area via the dustproof filter, and a second air supply unit accommodated in the dustproof area and configured to supply the cooling air introduced to the dustproof area by the first air supply unit toward the optical element.
