IMAGE PROCESSING METHOD FOR PLASMA DISPLAY PANEL |
摘要 |
<p>The present invention relates to a plasma display apparatus and image processing method thereof, by which low-gray-scale expression power can be enhanced and by which halftone noise occurring in video signal implementation can be reduced. According to an embodiment of the present invention, a plasma display apparatus includes an inverse gamma correction unit performing inverse gamma correction on data of a video signal inputted from outside and a halftone unit diffusing an error component resulting from multiplying a decimal value of a gray scale value of the inverse-gamma-corrected data by each error diffusion coefficient allocated according to the gray scale value into a neighbor cell.</p> |
