1. A method of generating a look-up table (LUT), comprising: determining first geometric correction information to transform an input domain pixel coordinate system of an input image to a panorama domain pixel coordinate system of a panoramic image in which a neighboring input image is connected to the input image; determining second geometric correction information to transform an output domain pixel coordinate system of an output image of the panoramic image output through a plurality of display devices to the panorama domain pixel coordinate system of the panoramic image; determining third geometric correction information to transform the output domain pixel coordinate system of the output image to the input domain pixel coordinate system of the input image based on the first geometric correction information and the second geometric correction information; and generating an LUT that maps the output domain pixel coordinate system of the output image to the input domain pixel coordinate system of the input image based on the third geometric correction information.
