Projectors with rear projection

Invert function

— function of "mirror reflection" of the image. Most often, horizontal inversion occurs in projectors, when the image is “reflected” from right to left — this function is used when projecting an image onto a translucent screen (when the projector and the viewer are on opposite sides of the screen). Vertical inversion is used in projectors with fixed keystone correction — due to their design, when mounted under the ceiling, such devices must be turned upside down, which requires the display image to be corrected accordingly.
