Abstract
An image data conversion method is provided. The method comprises the following steps of (a) receiving an original image data having three basic-color sub-pixel data and (b) calculating at least one color-enhancing sub-pixel data according to any two basic-color sub-pixel data so as to convert the original image data into an image data having at least three basic-color sub-pixel data and one color-enhancing sub-pixel data. The calculation of the color-enhancing sub-pixel data is represented as:
-
- wherein
- 0.8<var.<1.2,
- Di, Ei: two basic-color sub-pixel data
- S: the maximal grey level
- wherein
