Projector and control method of projector

A control method of a projector which includes an image projection unit for modulating light emitted from a light source and projecting the modulated light, alight source drive unit for driving the light source, and a light source control unit for controlling operation of the light source drive unit, comprising:

• outputting control command to the light source control unit and allowing the light source control unit to control operation of the light source drive unit based on the control command;
• obtaining response corresponding to control result from the light source control unit;
• determining whether control corresponding to the control command has been normally performed based on the response;
• and
• controlling the light source drive unit by outputting control information to the light source drive unit when the control corresponding to the control command is not normally performed.

A projector which modulates light emitted from a light source and projects the modulated light, comprising:

• a light source drive unit for driving the light source;
• a light source control unit for controlling operation of the light source drive unit;
• and
• a control unit which includes a UART unit connected with the light source control unit and GPIO unit connected with the light source drive unit, and allows the light source control unit to control operation of the light source drive unit by outputting control command from the UART unit,
• wherein the control unit controls operation of the light source drive unit using the GPIO unit when the light source drive unit is not controlled normally by the UART unit.
