A dynamic distortion correction apparatus 100 for use in an image projector 120. The invention includes a computer image generator 144 for generating a video image signal. A control circuit 102 processes the video image signal and regulates the clocking rate of a time-delayed video output signal. A modulator 104 is included for converting the video output signal to an optical image signal having a plurality of television raster lines. An optical device 148 is incorporated which orients each of the plurality of raster lines to compensate for distortion in the optical image signal at any viewing angle. A gimballed mirror 126 and a color projection optic device 178 are included to control the projection of the optical image signal onto a surface 110 to provide a display image 106. In a second embodiment, the optical device 148 is replaced by a correcting feature of the computer image generator which causes each of the raster lines to be parallel to every other raster line. In a third embodiment, the optical device 148 is replaced by a feature within the control circuit 102 for linearly spacing a plurality of pixels along each of the raster lines. Finally, in a fourth embodiment, the optical device 148 is replaced by a galvonometer sweep control 150 to linearly space the plurality of raster lines within the optical image signal. In a particular implementation, each of the above-recited elements are included to compensate for distortion in the optical image signal at any viewing angle.
