METHOD AND APPARATUS FOR PRODUCING RASTER IMAGE USEABLE IN EXPOSURE APPARATUS BASED ON DMD AND RECORDING MEDIUM FOR RECORDING PROGRAM FOR EXECUTING THE METHOD

摘要

A method for generating a raster image usable in a DMD-based exposure apparatus according to an embodiment of the present invention includes: a step of superposing a plurality of virtual pixel arrays to generate a superposed pixel array; a step of mapping the superimposed pixel array onto a virtual vector image; a step of generating a superimposed raster image by determining on/off of all pixels in the superimposed pixel array mapped onto the vector image; and a step of converting the superimposed raster image into one raster image.
