Keystone
An undesirable effect caused by projecting an image onto a surface at an angle.
The keystone effect distorts the dimensions of a projected image, making it appear shaped like a trapezoid. A keystoned image will appear larger at the top than on the bottom or if off axis to the side, one side will be taller than the other.
Many projectors have a "keystone correction" or "lens shift" feature to correct the image.
