    摘要: Disclosed is a backlight device that reduces elevated black levels and the visibility of flickering when displaying a video. A light-emitting unit (121) is provided with a plurality of light-emitting areas that individually emit illumination light, and illuminates a liquid crystal panel (110) with the illumination light from the plurality of light-emitting areas. A motion detection unit (150) detects image motion from an image signal. A brightness control unit (130) acquires a brightness determination reference value for each light-emitting area on the basis of the image signal, and in regards to each of the plurality of light-emitting areas, weights the acquired brightness determination reference value for each of the one or more light-emitting areas that constitute a weighting region and determines the light emission brightness value for each of the light-emitting areas on the basis of the weighting results. An LED driver (122) drives each of the plurality of light-emitting areas in accordance with the determined light emission brightness value for each of the light-emitting areas. The brightness control unit (130) dynamically sets the light-emitting areas that constitute the weighting areas in accordance with the detected motion.
