An image projector (1) includes: a light source (4a) to emit light; an image forming element (10) irradiated with the light from the light source and to form an image for projection onto a projection surface; a first controller (20) activated when the image projector is in a waiting state; and a second controller (21) that is not activated when the image projector is in the waiting state. In response to detection of an execution request for executing the image projector (1) in the waiting state at the first controller (20), the first controller (20) sets a power supply circuit (24) with an initial voltage to start supplying power to the light source (4a), and when the light source (4a) is lighted at the initial voltage, activates the second controller (21). |
