PROBLEM TO BE SOLVED: To provide an image projection device which allows for simple and reliable selection of a light-receiving sensor, capable of receiving light with high sensitivity, as an optimum light-receiving sensor that is brought into effective state at the time of standby mode, and to provide a selection method and a program.SOLUTION: Sensitivity measurement means 102 measures light reception sensitivity of a plurality of light-receiving means 107 for the signal sent from a remote controller by predetermined operation of a user. Determination means 103 determines the order of the strength of light reception sensitivity. Selection means 104 selects an optimum light-receiving sensor from the plurality of light-receiving means 107, based on the order of light reception sensitivity. Power supply control means 106 brings only the optimum light-receiving sensor, i.e., the light-receiving means 107, into effective state, and brings other light-receiving means 107 into disable state by turning off the power.SELECTED DRAWING: Figure 2 |
