PROJECTOR AND METHOD FOR CONTROLLING PROJECTOR
First Claim
1. A projector comprising:
- a projection section that includes alight source section that outputs first light and a light modulation section that outputs second light that is the first light modulated in accordance with image information, the projection section projecting the second light on a projection surface;
a power supply section that generates electric power that drives the projector and generates the electric power in both a case where the power supply section is connected to a first power supply having first power supply voltage and a case where the power supply section is connected to a second power supply having second power supply voltage lower than the first power supply voltage;
a light source drive section that controls an amount of the first light outputted from the light source section; and
a control section that allows execution of a function of controlling the amount of the first light from the light source section in the case where the power supply section is connected to the first power supply and restricts the execution of the function in the case where the power supply section is connected to the second power supply.

Abstract
A projector includes includes a light source section that outputs first light, a power supply section that generates the electric power in both a case where the power supply section is connected to a commercial AC power supply having first power supply voltage and a case where the power supply section is connected to a commercial AC power supply having second power supply voltage lower than the first power supply voltage, a light source drive section that controls the amount of first light, and a control section that allows execution of the function of controlling the amount of first light in the case where the power supply section is connected to the commercial AC power supply having first power supply voltage and restricts the execution of the function in the case where the power supply section is connected to the commercial AC power supply having second power supply voltage.

6. A method for controlling a projector including a projection section that includes a light source section that outputs first light and a light modulation section that outputs second light that is the first light modulated in accordance with image information, the projection section projecting the second light on a projection surface, and a power supply section that generates electric power that drives the projector and generates the electric power in both a case where the power supply section is connected to a first power supply having first power supply voltage and a case where the power supply section is connected to a second power supply having second power supply voltage lower than the first power supply voltage, the method comprising:
-
controlling an amount of the first light outputted from the light source section; and allowing execution of a function of controlling the amount of the first light from the light source section in the case where the power supply section is connected to the first power supply and restricting the execution of the function in the case where the power supply section is connected to the second power supply.
