Abstract:
1. A method for reducing memory consumption when carrying out Edge Enhancement in a multiple beam pixel apparatus, applied to a multiple beam pixel apparatus with n input units, the apparatus being provided with (n+4) buffers and four static random access memories (SRAM), and the first nine rows of the (n+4) buffers being an operation block; the method comprising the following steps: filling the operation block with serial data sequentially, wherein as for the first four columns of serial data in the operation block, since the first four buffers are all fully occupied, the serial data without being stored in each of the buffers are temporarily stored in the four SRAMs; taking out n 9 by 5 tables for detecting required by the Edge Enhancement according to the arranging order of each of the buffers in the operation block; carrying out the edge enhancement technology (EET) adjustment operation to the central pixels required to be edge enhanced in the n 9 by 5 tables; outputing the n central pixel values being adjusted or with no need of being adjusted; moving the serial data having already been read by the (n+4) buffers and the four SRAMs; and reading the next bit data with each of the n input units, wherein n is an integer and is larger than 1.
