The innovation of using optics design or other methods to apply a "negative" keystone to the image, which will partially cancel the effects of keystoning. If you aim a projector with keystone correction at a screen with the lens level with the middle of the screen, you will note that the image at the bottom is wider than the top. When the projector is in normal position, pointing upward 10-25 degrees, the resulting image is fairly rectangular.
Keystoning is caused when the projected image is not perpendicular to the screen, making the top and bottom of the image different widths for a trapezoid effect.
