Image processing method and pixel arrangement used in the same
First Claim
1. An image processing method for generating multi-color data comprised of three primary-color sub-pixels and a brightness-enhancing sub-pixel, where a combination selected three at a time from these sub-pixels constituting a target pixel for the image processing method, the method comprising the steps of:
- converting a three-color pixel into a four-color pixel by extracting a white component from the three-color pixel, where the sub-pixels of the four-color pixel identical with those of the target pixel are represented by first numerical values, and the sub-pixel of the four-color pixel different to that of the target pixel is represented by a second numerical value;
providing the target pixel with the first numerical values and with third numerical values discarded by neighboring pixels of the target pixel; and
correlating the first numerical values with the third numerical values to determine the actual output numerical values of the target pixel.

Abstract
An image processing method is provided for generating multi-color data comprised of three primary-color sub-pixels and a brightness-enhancing sub-pixel, where a combination selected three at a time from these sub-pixels constituting a target pixel for the image processing method. First, a three-color pixel is converted into a four-color pixel, where the sub-pixels of the four-color pixel identical with those of the target pixel are represented by first numerical values, and the sub-pixel of the four-color pixel different to that of the target pixel is represented by a second numerical value. Then, the first numerical values are correlated with third numerical values discarded by neighboring pixels of the target pixel to determine the actual output of the target pixel.

10. A image processing method for generating multiple rows of pixel data comprised of three primary-color sub-pixels and a brightness-enhancing sub-pixel, where each two adjacent sub-pixels in one row are distinct from each other and two identical sub-pixels that are respectively arranged in two immediately adjacent rows are staggered in relation to each other with two sub-pixel positions, and a combination selected three at a time from these sub-pixels constituting a target pixel for the image processing method, the method comprising the steps of:
-
converting a three-color pixel into a four-color pixel by extracting a white component from the three-color pixel, where the sub-pixels of the four-color pixel identical with those of the target pixel are represented by first numerical values, and the sub-pixel of the four-color pixel different to that of the target pixel is represented by a second numerical value;
