THREE-DIMENSIONAL IMAGE DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a three-dimensional image display device capable of securing and maintaining the solid display accuracy of a three-dimensional image, for example, by correcting the position of a pixel projected by a projector with respect to the position of an optical element such as a lens array.

SOLUTION: The image display device for projecting an optical beam to a projected surface based on input image information to display an image on the projected surface includes: a first optical system having a light source for emitting an optical beam and a mirror for scanning the optical beam emitted from the light source to project it to the projected surface; a second optical system having a projected surface and a detection sensor for detecting the optical beam projected to the projected surface; and a module control circuit for deforming the image within the target range of the projected surface to project it based on the pixel position on the projected surface where the optical beam projected by the mirror is detected by the detection sensor and a mirror angle for scanning the optical beam.
