DISPLAY DEVICE, DATA PROCESSING APPARATUS AND METHOD THEREOF

摘要

According to the present invention, the data processing apparatus includes: a diagonal line recognition part to determine whether 3-by-3 RB image data containing red image data and blue image data shows a diagonal line; an odd line rendering filter in which a scale factor corresponding to the center data of the 3-by-3 RB image data is set to one; and an even line rendering filter in which a scale factor corresponding to the data in the previous row of the center data is set to one. In case the 3-by-3 RB image data shows a diagonal line, and if the center data of the 3-by-3 RB image data is odd line data, the 3-by-3 RB image data is rendered through the odd line rendering filter; and if the center data of the 3-by-3 RB image data is even line data, the 3-by-3 RB image data is rendered through the even line rendering filter.
