Abstract
A display apparatus for displaying color images on a screen by projecting each-color image beams modulated with a display device includes a memory storing correction data exhibiting a registration deviation amount on the screen; a displacement calculating unit calculating the registration deviation amount every one pixel of at least one-color signal based on the correction data stored in the memory; a correcting unit correcting the signal level of the one-color signal so that the signal level becomes in proportion to a brightness level on the screen; and a registration deviation correcting unit correcting the registration deviation of the one-color signal every one pixel by interpolation arithmetic processing of the color signal corrected with the correcting unit based on the registration deviation amount calculated with the displacement calculating unit, wherein the display device of the corresponding color is driven by the color signal corrected with the registration deviation correcting unit.
