A local dimming method based on improved multi ... - ScienceDirect
WebSeveral backlight dimming algorithms exist; many of them focus on reducing power consumption while keeping an acceptable quality [3][4][5]. In [6], backlight dimming is modeled as an image optimization problem. The optimum backlight illumination defined by a cost function and by the input image is found; the result is a compromise between WebJul 1, 2015 · Now a days in most of the dimming algorithms, the following compensation is applied: (8) (L 255) γ B L = (L ′ 255) γ B L ′ where BL and BL′ are the BLU luminance before and after dimming, respectively. L and L′ are the grayscale of LC pixels before and after dimming, respectively.Such a compensation does not change the ratio between the max … 厭 読み方
