Calibration Step for use in Connection with Method and System for Creating Wide-Screen Picture-Dominance Effect in a Conventional Motion-Picture Theater

A system for changing formats during the course of a theatrical motion picture presentation through the use of a computer program, in which said change between formats utilizing different aspect ratios is activated by commands embedded into said computer program, which forms part of the automation system that controls the projector located in the auditorium in which said motion pictures forming said presentation are displayed;

• said computer program also containing correction information which directs the projection of each pixel of each image of said motion pictures onto a curved screen located in said auditorium, in a manner that eliminates distortion;
• said direction of said pixels further changing as part of said change of formats with different aspect ratios, and in which said direction of said pixels is calibrated manually for each format and aspect ratio and on an a one-time basis by an operator inside the auditorium in which the invention is installed visually inspecting a test image or images projected onto said screen and imparting commands to said projector system to correct said test image or images, such that all horizontal and vertical lines on such test image or images appear straight and orthonormal as projected onto said screen;
• the information contained in said commands further being embedded into the software which controls said projection system as pre-set calibrations of said system for future exhibition of motion pictures in said auditorium for each of the formats and aspect ratios for which said calibrations were made;
• with the result that said images appear distortion-free to the viewers of said images in said auditorium.
