Abstract: An image projection device is disclosed. An image projection device according to an embodiment of the disclosure may comprise: memory storing information about a reference image, an image projection unit comprising a projector configured to project an image or a video, a communication unit comprising communication circuitry, at least one processor, comprising processing circuitry, connected to the memory, the image projection unit, and the communication unit. In an embodiment, at least one processor, individually and/or collectively, may be configured to control the image projection device to: project a first corrected image generated based on first keystone correction information and the reference image, onto a screen, receive, from a user device, a captured image obtained by capturing the first corrected image projected onto the screen, generate second keystone correction information based on information about positions of at least four first markers included in the reference image, information about positions of at least four second markers included in the captured image, and the first keystone correction information, and project a second corrected image generated based on the second keystone correction information and the reference image. The at least four second marker may be disposed at positions corresponding to the positions of the at least four first markers.
