An image projection apparatus includes an optical modulation element, a lighting optical unit, a projection unit, and a shifting unit. The optical modulation element generates an image from light emitted from a light source. The lighting optical unit is configured to guide the light emitted from the light source to the optical modulation element. The projection unit projects the image generated by the optical modulation element. The shifting unit relatively shifts the optical modulation element with respect to the lighting optical unit. The shifting unit also generates driving forces to shift the optical modulation element, respectively, in a vertical direction, in a direction of being inclined by a first angle less than 90 degrees with respect to the vertical direction, and in a direction of being inclined by a second angle less than 90 degrees in an opposite side of the first angle.

Disclosed is a method for improving the calibration of multiple projector systems in Spatial Augmented Reality systems where multiple projectors are used to project images directly onto objects of interest. The methods and system described herein improve the calibration of multiple projector systems in order to improve the alignment and clarity of projected images by reducing ghosting that can occur with poorly aligned projectors. The system uses a planar photodiode and the projector is used to project a plurality of projection regions, such as scan lines, across the planar photodetector and calculating the position based on weighting measurements by the measured light intensity and projected images in SAR.
