Abstract
An image processing method is provided. The image processing method includes obtaining a least significant bit (LSB) associated with a pixel block. Further, two bits are reduced from a bit number of each of the pixels of the pixel block. Thereafter whether to carry the pixel or not is determined according to the LSB. When the LSB is 01 or 11, the carry manners of each pixel of the pixel block in two consecutive frames are asymmetric one to another. Further, under the conditions of when the LSB is 01 and 11, respectively, the carry manners of the pixels of the pixel block mutually compensate. Therefore, the display performance of a display is improved.

An image processing method, comprising:
- obtaining a least significant bit (LSB) associated with a pixel block, wherein the LSB is a 2-bit number, the pixel block comprises 4×4 pixels which are (1, 1), (1, 2), (1, 3), (1, 4), (2, 1), (2, 2), (2, 3), (2, 4), (3, 1), (3, 2), (3,3),(3,4), (4, 1), (4, 2), (4,3), and (4, 4), respectively;
- reducing two bits from a bit number of each of the pixels of the pixel block;
- determining whether to carry each of the pixels or not according to the LSB;
- carrying the pixels (1, 1), (1, 3), (3, 1), and (3, 3) of the pixel block and remaining the rest pixels of the pixel block non-carried in a first frame, carrying the pixels (1, 4), (2, 2), (3, 4), and (4, 2) of the pixel block and remaining the rest pixels of the pixel block non-carried in a second frame, carrying the pixels (2, 1), (2, 3), (4, 1), and (4, 3) of the pixel block and remaining the rest pixels of the pixel block non-carried in a third frame, and carrying the pixels (1, 2), (2, 4), (3, 2), and (4, 4) of the pixel block and remaining the rest pixels of the pixel block non-carried in a fourth frame, when the LSB is 01;
- and
- remaining the pixels (1, 1), (1, 3), (3, 1), and (3, 3) of the pixel block non-carried and carrying the rest pixels of the pixel block in the first frame, remaining the pixels (1, 4), (2, 2), (3, 4), and (4, 2) of the pixel block non-carried and carrying the rest pixels of the pixel block in the second frame, remaining the pixels (2, 1), (2, 3), (4, 1), and (4, 3) of the pixel block non-carried and carrying the rest pixels of the pixel block in the third frame, and remaining the pixels (1, 2), (2, 4), (3, 2), and (4, 4) of the pixel block non-carried and carrying the rest pixels of the pixel block in the fourth frame, when the LSB is 11.
