CARRY TABLE GENERATING METHOD

摘要

A carry table generating method is provided for generating N dither carry tables, so as to dither N pixel blocks, wherein a size of the pixel block is N×N, and N is an integer greater than 1. The carry table generating method comprises the following steps: reading a plurality of basic tables from a memory, wherein the base tables are corresponding to a plurality of basic blocks, the number of the basic blocks is smaller than N, and the size of the basic blocks is smaller than the size of the pixel blocks; expanding the size of the basic tables by a first conversion procedure, and expanding the number of the basic blocks by a second conversion procedure; and generating the dither carry tables by using the expanded basic blocks.

1. A carry table generating method for generating N dither carry tables, so as to dither N pixel blocks, wherein a size of the pixel block is N×N, N is an integer greater than 1, the carry table generating method comprising:
reading a plurality of basic tables from a memory, wherein the base tables are corresponding to a plurality of basic blocks, the number of the basic blocks is smaller than N, and the size of the basic blocks is smaller than the size of the pixel blocks; expanding the size of the basic tables by a first conversion procedure in a timing controller, wherein the step of expanding the size of the basic tables by the first conversion procedure comprises:
in the first conversion procedure, expanding the size of the basic blocks by using a combination among the basic blocks or a combination among the basic blocks and a plurality of first extended blocks; expanding the number of the basic blocks by a second conversion procedure in the timing controller, wherein the step of expanding the number of the basic blocks by the second conversion procedure comprises:
in the second conversion procedure, re-arranging sub-blocks in the basic blocks to form a plurality of second extended blocks; andexpanding the number of the basic blocks by using the second extended blocks; and generating the dither carry tables by using the expanded basic blocks through the timing controller.
