Document Type and Number:
Japanese Patent JP2022114988
Kind Code:
A
Abstract:
To provide an image projection device that allows easy adjustment of a focus state during tilt projection.SOLUTION: An image projection device is an image projection device that modulates light output from a light source and displays a projection image on a projection surface through a projection optical system, and has tilt means that tilts an image surface that is a position at which the projection image is focused; and image creation means that deforms an input image according to an operation input performed by a user to create a deformed image. The tilt means tilts the image surface by using the amount of tilt of the image surface based on the amount of deformation of the deformed image with respect to the input image.SELECTED DRAWING: Figure 1
