Abstract: front page image
(EN)A display device is provided with: an LED control unit (4) which, using information relating to the measured luminance of an LED (10) acquired by a photosensor (11) and control information relating to the LED (10) including position information relating to the LED (10), performs control for correcting the output luminance of the LED (10) with the measured luminance deviating from reference luminance or an LED (10) disposed therearound; and a liquid crystal control unit (3) which, on the basis of a picture signal inputted from a picture signal processing circuit (2) and subjected to picture signal processing, and the control information relating to the LED (10) inputted from the LED control unit (4), controls the level of the picture signal to be given to a pixel corresponding to the LED (10) the output luminance of which has been corrected, wherein the reference luminance is luminance which the LED (10) should output.
(FR)L'invention concerne un dispositif d'affichage comprenant : une unité de commande de diodes (4) qui, en utilisant des informations sur la luminance mesurée d'une diode (10), obtenue par un photodétecteur (11) et des informations de commande concernant la diode (10), y compris des informations de position concernant la diode (10), opère une commande afin de corriger la luminance de sortie de la diode (10) sur la base de l'écart de la luminance mesurée par rapport à une luminance de référence ou à une diode (10) adjacente ; une unité de commande de cristaux liquides (3) qui, sur la base d'un signal d'image fourni par un circuit de traitement de signal d'image (2) et soumis au traitement du signal de l'image et des informations de commande concernant la diode (10), fournies par l'unité de commande de diodes (4), commande le niveau du signal d'image à donner à un pixel correspondant à la diode (10) dont la luminance de sortie a été corrigée. La luminance de référence est la luminance que la diode (10) devrait fournir.
(JA) フォトセンサ(11)が取得したLED(10)の実測輝度の情報と、LED(10)の位置情報とを含むLED(10)の制御情報を用いて、実測輝度が基準輝度からずれたLED(10)、またはその周辺に配置されたLED(10)の出力輝度を補正する制御を行うLED制御部(4)と、映像信号処理回路(2)から入力された映像信号処理後の映像信号と、LED制御部(4)から入力されたLED(10)の制御情報とを元に、上記出力輝度を補正したLED(10)に対応する画素に与える映像信号のレベルを制御する液晶制御部(3)とを備え、上記基準輝度は、LED(10)が本来出力すべき輝度である。
