Patent ID: 7184008

Claim:
A liquid crystal displaying method, comprising: inputting an input image to be displayed on a displaying region which is a part of a liquid crystal display, the input image having an input luminance component (Y) and an input color-difference components (U, V); calculating a luminance difference by subtracting a delayed luminance component (Yd) from the input luminance component (Y), the delayed luminance component (Yd) being the input luminance component (Y) of the input image which has been delayed for one frame period; calculating color-difference differences by subtracting a delayed color-difference components (U 0 , V 0 ) from the input color-difference components (U, V) the delayed color-difference components (U 0 , V 0 ) being the input color-difference components (U, V) of the input image which has been delayed for one frame period; multiplying each of the luminance difference and the color-difference differences by an emphasis coefficient α; calculating an emphasized luminance component (Yα) by adding the delayed luminance component (Yd) to the luminance difference multiplied by the emphasis coefficient α; calculating emphasized color-difference components (Uα, Vα) by adding the delayed color-difference components (U 0 , V 0 ) to the color difference differences multiplied by the emphasis coefficient α; converting the emphasized luminance component (Yα) and the emphasized color-difference components (Uα, Vα) to an emphasized red-level component (Rα), an emphasized green-level component (Gα) and an emphasized blue-level component (Bα); and displaying and emphasized image on the displaying region based on the emphasized red-level component (Rα), the emphasized green-level component (Gα) and the emphasized blue-level component (Bα).
