Abstract:
1. A projector comprising: an interface section that has a plurality of connection terminals to which image information is input from source devices that are different from each other, a projecting section that projects an image based on the image information, a storage control section that stores identification information that denotes the source device outputting the image information in a storage section, an instruction information input section to which instruction information is input, a power-supply, a power-supply control section that controls the power-supply, a determination section that determines based on the instruction information, and a control information generation section that generates control information, wherein the projecting section includes: wherein, the determination section determines whether the instruction information is information that designates switching on the power-supply or not, the power-supply control section switches on the power-supply in a case where the instruction information is determined to be information that designates switching on the power-supply by the determination section, the control information generation section generates, as the control information, switching on control information that designates switching on the source device that is denoted with the identification information in a case where the instruction information is determined to be information that designates switching on the power-supply by the determination section, the interface section outputs the switching on control information to the source device that is denoted with the identification information, the interface section starts the output of the switching on control information before the lamp control section switches on the lamp, and the identification information denotes the source device that outputs the image information just previous the instruction in a case where the instruction information is determined to be information that designates switching off the power-supply by the determination section.
