Abstract
A full field memory based stroke written vector occluder consisting of a first full field memory as the primary occlusion mechanism, and a second full field memory as a quantized error correction occlusion function. The apparatus includes a mechanism for generating the address of the second full field memory from the address of the first full field memory added to the least significant bit of the address plus or minus 1. The apparatus also includes an OR gate to provide the real occlusion function which is the result of accessing either or both of the full field memories.
