PROJECTOR, IMAGE DATA CONVERSION METHOD, AND RECORDING MEDIA FOR RECORDING IMAGE DATA CONVERSION PROGRAM

摘要

A projector is provided with: an image data converting unit 200 that generates output image data by performing predetermined image data conversion on input image data; a multi-plate electro-optical modulator 300 having plural electro-optical modulating elements 301 to 303 each of which generates an image light by modulating a light from an illumination device according to output image data from the image data converting unit 200; and a projection system that projects plural image lights generated in the multi-plate electro-optical modulator 300 onto a projection surface as plural projection images. The image data converting unit 200 performs the image data conversion on the input image data for each electro-optical modulating elements 301 to 303 in the multi-plate electro-optical modulator 300 by taking into account positional displacement information about 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 the three axes.
