Projector and control method for projector

A control method for a projector which includes a light source, a modulating unit that modulates light emitted from the light source, and a light adjustment mechanism that reduces an amount of light incident on the modulating unit from the light source, and which reduces the light emitted from the light source by the light adjustment mechanism and projects the light, the method comprising:

• acquiring an image from an image source;
• modulating the light emitted from the light source, based on the acquired image;
• performing light adjustment control by the light adjustment mechanism based on the acquired image;
• stopping execution of the light adjustment control when at least one of an operating state of the projector and a state of the acquired image meets a predetermined condition;
• and
• performing control to lower a light reduction level by the light adjustment mechanism when the light adjustment mechanism maintains a predetermined light-adjusted state.

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,
• the image acquiring unit acquires an image inputted from an external device, and
• the light adjustment control unit stops the execution of the light adjustment control when input of an image from the external device is stopped.

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;
• 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;
• and
• a shutter mechanism for shutting off the light emitted from the light source;
• 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, and
• the light adjustment control unit stops the execution of the light adjustment control when the light is shut off by the shutter mechanism.
