发明名称 IMAGE DISPLAY DEVICE AND IMAGE DISPLAY METHOD
摘要 <p>In the present liquid crystal display device, an LED output value correction section (513) included in an area-active drive processing section (5) corrects LED data Dbl obtained by an LED output value calculation section (512) with reference to a luminance correction LUT (13), such that the luminance in the area from an intermediate value to near a maximum value shifts to a higher degree. Thus, even if the backlight luminance is low (typically, the mean luminance of an input image is low), contrast ratio is enhanced, thereby preventing a tone jump (insufficient luminance) at high tone levels due to an insufficient backlight luminance.</p>
