Abstract
(EN)
Provided is a drive device for driving a display device, which displays input video data by dividing one frame into plural subframes and by totalizing the displays of the individual subframes. The drive device comprises a subframe data creation unit for creating subframe data corresponding to each subframe, and a subframe period fixing unit for making such a setting that at least one subframe period may have a constant value irrespective of the kind of the input video data. Thus, the display quality can be prevented from varying with respect to various kinds of input video signals.

La présente invention concerne un dispositif de commande pour piloter un dispositif d'affichage, qui affiche des données vidéo d'entrée en divisant une trame en plusieurs sous-trames et en combinant les résultats des différentes sous-trames. Le dispositif de commande comprend une unité de création de données de sous-trame qui fournit les données correspondant à chaque sous-trame et une unité de correction des périodes de sous-trame qui effectue un réglage tel qu'au moins une période de sous-trame peut avoir une valeur constante sans tenir compte du type des données vidéo d'entrée. Ceci permet d'éviter la variation de la qualité d'affichage due à divers types de signaux vidéo d'entrée.
(JA)
 1フレームを複数のサブフレームに分割し、各サブフレームの表示の総和によって入力映像データの表示を行う表示装置を駆動する表示装置の駆動装置であって、各サブフレームに対応するサブフレームデータを生成するサブフレームデータ生成部と、少なくとも1サブフレーム期間が、上記入力映像データの種類によることなく一定値となるような設定を行うサブフレーム期間固定部と、を備える。これにより、各種の入力映像信号に対して表示品位がばらつかないようにすることができる。
