an image processor, for reading from the memory the first portion and the second portion of the current image data, and only the first portion of the adjacent image data for image processing of the current image data of the current frame.

2. The system as claimed in claim 1 , wherein the image processor is for overdriving liquid crystal cells.

3. The system as claimed in claim 1 , wherein:

the image processor comprises a data combining unit, for combining the first portion and the second portion of the current image data to restored data, and

the image processor performs the image processing according to the restored data and the first portion of the adjacent image data.

4. The system as claimed in claim 1 , wherein the data slicer stores the first portion and the second portion of the current image data into the memory according to a first frequency, and the image processor reads the first portion and the second portion of the current image data from the memory according to a second frequency different from the first frequency, so as to adjust a vertical blanking interval (VBI) of the current image data.

5. The system as claimed in claim 1 , further comprising:

a memory interface unit, for connecting the data slicer and the image processor to the memory.

6. The system as claimed in claim 1 , further comprising:

an image pre-processing apparatus, for performing pre-processing on the plurality of image data before the plurality of image data are inputted into the data slicer.

7. The system as claimed in claim 6 , wherein the pre-processing is white balance calibration, brightness adjustment, hue calibration or sharpening processing.

8. The system as claimed in claim 1 , wherein the data slicer comprises a first-in-first-out (FIFO) buffer.

9. The system of claim 1 , wherein the first portion of the adjacent image data read by the image processor consists only of the MSB data of each of the pixels.

10. An image processing method, for processing current image data of a current frame and adjacent image data of an adjacent frame, comprising:

(a) dividing each of the plurality of image data into a first portion and a second portion, wherein the plurality of image data comprise data of a plurality of pixels, the first portion comprises at least one most significant bit (MSB) data of each of the pixels, and the second portion comprises at least one least significant bit (LSB) data of each of the pixels;

(b) storing the first portion and the second portion into a memory; and

(c) reading from the memory the first portion and the second portion of the current image data, and only the first portion of the adjacent image data for image processing of the current image data of the current frame.

11. The method as claimed in claim 10 , wherein the image processing is for overdriving liquid crystal cells.

12. The method as claimed in claim 10 , wherein the step (c) comprises:

combining the first portion and the second portion of the current image data to restored data; and

performing the image processing according to the restored data and the first portion of the adjacent image data.

13. The method as claimed in claim 10 , wherein in the step (b) the first portion and the second portion of the current image data are stored into the memory according to a first frequency, and in the step (c) the first portion and the second portion of the current image data are read from the memory according to a second frequency different from the first frequency, so as to adjust a vertical blanking interval (VBI) of the current image data.

14. The method as claimed in claim 10 , before the step (a), further comprising:

performing pre-processing on the plurality of image data.

15. The method as claimed in claim 14 , wherein the pre-processing is white balance calibration, brightness adjustment, hue calibration or sharpening processing.

16. The method as claimed in claim 10 , wherein in the step (a) the plurality of image data are divided by an first-in-first-out (FIFO) buffer.

17. The method of claim 10 , wherein reading from the memory of only the first portion of the adjacent image data consists only of reading from memory of the MSB data of the adjacent image data.

18. An image processing system, for processing current image data of a current frame and adjacent image data of an adjacent frame, comprising:

a data slicer, for dividing each of the plurality of image data into a first portion and a second portion to be stored into a memory, wherein the plurality of image data comprise data of a plurality of pixels, the first portion comprises at least one most significant bit (MSB) data of each of the pixels, and the second portion comprises at least one least significant bit (LSB) data of each of the pixels; and

an image processor, for reading from the memory the first portion and the second portion of the current image data, and only the first portion of the adjacent image data for image processing of the current image data of the current frame.

19. The system as claimed in claim 18 , wherein the data slicer stores the first portion and the second portion of the current image data into the memory according to a first frequency, and the image processor reads the first portion and the second portion of the current image data from the memory according to a second frequency different from the first frequency, so as to adjust a vertical blanking interval (VBI) of the current image data.

20. The system of claim 18 , wherein the first portion of the adjacent image data read by the image processor consists only of the MSB data of each of the pixels.
