ABSTRACT:
A projector is provided an image data converting unit that generates output image data by performing predetermined image data conversion on input image data, a multi-panel electro-optical modulating device having plural electro-optical modulating elements each of which generates an image light by modulating a light from an illumination device based on output image data from the image data converting unit, and a projection system that projects plural image lights generated in the multi-panel electro-optical modulating device onto a projection surface as plural projection images. The image data converting unit performs the image data conversion on the input image data for each electro-optical modulating element in the multi-panel electro-optical modulating based on positional displacement information of displacements in position among the plural projection images. It is thus possible to correct displacements in position even when the respective electro-optical modulating elements are misaligned due to rotations about three axes.
