Patent ID: 6930794

Claim:
A method for generating printed images of a graphic pattern of a movie picture to be displayed for moving observers using a long display panel composed of said graphic pattern and a plate made up of a plurality of cylinder converging lenses arranged parallel to each other with a common focal plane, comprising: a) storing a succession of digital data blocks corresponding to individual frames in digital code of the movie picture to be displayed and assigning a label to each of these digital data blocks that identifies its position in a cinematographic sequence; b) defining an integer variable q which can assume N pages values, where initially q is set to its first value, where each page is a printed unit of the graphic pattern and N pages is the total number of pages of the graphic pattern; c) generating a two-dimensional array of byte sets, able to be recognized as a blank image in a definite digital graphical format, of size (N lenses p)×H, where the array can be thought of as formed by N lenses adjacent sectors of size p×H (hereafter, fringes) and is labeled by a name (page-) together with the correlative number q, where N lenses is the number of lenses in the lenticular plate, p is the distance between fringes in the graphic pattern, and H is the height of a fringe; d) calling successively and resizing on calling the data blocks, or byte arrays representing the movie frames in digital format by a graphical resize sub-routine to a size w×H, in array or pixel units, where w≦p, where each time a frame is called and resized it is pasted repeatedly in N rep consecutive fringes of the page-q array, where w is the size in the principal direction of a fringe; e) once the N lenses fringes of the page-q array are all filled by resized frames, closing the array and storing as a digital image, replacing the value of q with the next value in the succession, if available, and the process returns to step c), and if step e) occurs before the pasting of the N rep resized copies of a frame is completed, the preparation of the next page will start pasting the residual copies to complete the N rep ones, where N rep is number of repetitions of the fringes associated with each frame of the movie picture; f) eventually, pasting a small identification image containing the number q before closing and storing the page-q array; g) if no next value of q is available in the succession of N pages elements the process does not return to step c), but ends.
