Abstract
An image projection apparatus includes a first light modulation element configured to modulate a first light emitted from a light source and to generate a second light, and a second light modulation element configured to modulate the second light. The first light modulation element is configured to receive the first light onto a modulable pixel area that can modulate the first light, the modulable pixel area including an effective pixel area that can modulate the first light and a peripheral pixel area arranged at the periphery of the effective pixel area. The image projection apparatus further comprises a controller configured to control pixels of the peripheral pixel area such that light from the peripheral pixel area does not reach the second light modulation element.
