| 20090289879 | IMAGE DISPLAY DEVICE AND IMAGE DISPLAY METHOD - According to one embodiment, an image display device includes an image-signal input module, an image-quality corrector, a light emitter, and a liquid-crystal display module. The image-signal input module receives an image signal. The image-quality corrector performs, based on an image-quality correction amount, an image-quality correction process on the image signal. The light emitter includes a plurality of light sources for emitting light. The liquid-crystal display module modulates, among light emitted from the light sources, light transmitted through the liquid crystal to display an image according to the image signal subjected to the image-quality correction process. The light emitter emits the light according to the image signal with less image-quality correction amount than that of the image signal subjected to the image-quality correction process. | 11-26-2009 |
| 20090289890 | LIGHT-EMISSION CONTROL DEVICE AND LIQUID CRYSTAL DISPLAY APPARATUS - According to one embodiment, a light-emission control device controls light emission of light sources of a light emitter including a plurality of light source areas each corresponding to one of the light sources, and includes a virtual light-value calculator, a light-value calculator, and a light controller. The virtual light-value calculator calculates a virtual light value for each virtual light source area including a light source area and a virtual area obtained by virtually dividing the light emitter into areas different in size from the light source areas. The light-value calculator calculates a light value of a light sources corresponding to the light source area based on the virtual light value. The light controller lights the light source based on the light value. | 11-26-2009 |
| 20090290091 | LIGHT-EMISSION CONTROL DEVICE AND LIQUID-CRYSTAL DISPLAY APPARATUS - According to one embodiment, a light-emission control device controls light emission of light sources of a light emitter including a plurality of light source areas each corresponding to one of the light sources, and includes a light-value calculator, a light-value modifying module, and a light controller. The light-value calculator calculates a light value for each of the light source areas. The light source areas include a target area for which a light value is to be modified and surrounding areas surrounding the target area. The light-value modifying module modifies a light value calculated for the target area using light values for the surrounding areas. The light controller lights a light source in the target area based on the modified light value. | 11-26-2009 |
