Projector and method for controlling the same

摘要

A projector includes a power receiving terminal, a light source that emits light based on electric power supplied to the power receiving terminal, a light diffuser that adjusts the degree of diffusion of the light from the light source, a specifying section that alternately specifies one of illumination projection and image projection every time electric power supply to the power receiving terminal is started, and a light diffusion controller that controls the light diffuser so that when the specifying section specifies the illumination projection, the light diffuser diffuses the light from the light source, whereas when the specifying section specifies the image projection, the light diffuser transmits the light without substantially diffusing the light.

1. A projector comprising:
a power receiving terminal; a light source that emits light based on electric power supplied to the power receiving terminal; a light diffuser that adjusts the degree of diffusion of the light from the light source; a specifying section that alternately specifies one of first projection and second projection every time electric power supply to the power receiving terminal is started; and a light diffusion controller that controls the light diffuser so that when the specifying section specifies the first projection, the light diffuser diffuses the light from the light source, whereas when the specifying section specifies the second projection, the light diffuser transmits the light without substantially diffusing the light, wherein the specifying section automatically defaults to the first and second projection mode in an alternating way when the power supply is started.
