Abstract:
An image projection apparatus includes a light source configured to cause a light-emitting material to emit light by an electric discharge between a pair of electrodes; an image forming unit configured to form an image by modulating intensity of the light emitted from the light source; a receiving unit configured to receive a power-off input that triggers stopping power supply to the image projection apparatus; and an electric-power control unit configured to increase electric power supplied to the electrodes before stopping power supply to the image projection apparatus when the receiving unit receives the power-off input.
