Title (EN) IMAGE DISPLAY METHOD AND IMAGE DISPLAY DEVICE
(FR) PROCÉDÉ D’AFFICHAGE D’IMAGE ET DISPOSITIF D’AFFICHAGE D’IMAGE
(JA) 映像表示方法および映像表示装置
Abstract:
(EN) An image display method according to the present invention comprises a step (S11) of acquiring an image signal and a visible light signal, a step (S12) of modulating the visible light signal in order to determine a luminance variation pattern, a step (S13) of transmitting the visible light signal during a first period that is a part of the frame display period by changing the luminance of an LED in a panel in accordance with the luminance variation pattern, a step (S14) of correcting a second gradation during a second period subsequent to the first period in accordance with a first gradation, the first gradation representing the gradation for the luminance variation pattern during the first period and the second gradation being represented by an image signal, and a step (S15) of turning on the LED with the corrected second gradation during the second period.
(FR) La présente invention concerne un procédé d’affichage d’image qui comprend une étape (S11) consistant à acquérir un signal d’image et un signal de lumière visible, une étape (S12) consistant à moduler le signal de lumière visible de façon à déterminer un motif de variation de luminance, une étape (S13) consistant à émettre le signal de lumière visible durant une première période qui est une partie de la période d’affichage de trame par modification de la luminance d’une diode électroluminescente (DEL) dans un panneau conformément au motif de variation de luminance, une étape (S14) consistant à corriger une seconde gradation durant une seconde période après la première période conformément à une première gradation, la première gradation représentant la gradation pour le motif de variation de luminance durant la première période et la seconde gradation étant représentée par un signal d’image, et une étape (S15) consistant à allumer la DEL avec la seconde gradation corrigée durant la seconde période.
(JA) 本開示の映像表示方法は、映像信号および可視光信号を取得するステップ(S11)と、可視光信号を変調することにより、輝度変化パターンを決定するステップ(S12)と、フレーム表示期間の一部の期間である第1の期間において、パネルに含まれるLEDを輝度変化パターンにしたがって輝度変化させることにより、可視光信号を送信するステップ(S13)と、第1の期間の後にある第2の期間における、映像信号によって示される第2の階調を、第1の期間の輝度変化パターンの階調である第1の階調に応じて補正するステップ(S14)と、第2の期間において、補正された第2の階調でLEDを点灯させるステップ(S15)を含む。
