PROJECTION DISPLAY APPARATUS |
摘要 |
A projection display apparatus according to a first feature includes: an imager that modulates light emitted from a light source; and a projection unit that projects the image light modulated by the imager onto a projection plane. The projection plane includes a projectable region where the image light can be projected. The projectable region includes a projection region on which the image light is projected based on an image signal and a non-projection region other than the projection region. The projection display apparatus further includes: an adjustment unit that adjusts the shape of the projection region within the projectable region; and a control unit that displays additional information at least in the non-projection region within the projectable region.
