Abstract | The present invention relates to an image display device and a control method therefor. The objective of the present invention is to restore a quantization error of a video signal by only expanding the number of bits of a restored image relative to the number of bits of an input image without expanding the number of bits in an image signal processing. To this end, the image display device according to the present invention comprises: a signal input unit for receiving an input image signal; an image processing unit for performing image processing of the input image signal, comparing the input image signal with the processed image signal to confirm an image processing type, obtaining restoration information of the processed image signal according to the confirmed image processing type, and performing re-mapping of the processed image signal by using restoration information to restore an error of the processed image signal; and an output unit for outputting an image signal with the error restored.
La présente invention concerne un dispositif d'affichage d'image et son procédé de commande. L'objectif de la présente invention est de réparer une erreur de quantification d'un signal vidéo en augmentant uniquement le nombre de bits d'une image restaurée par rapport au nombre de bits d'une image d'entrée, sans augmenter le nombre de bits dans un traitement de signal d'image. À cet effet, le dispositif d'affichage d'image selon la présente invention comprend : une unité d'entrée de signal pour recevoir un signal d'image d'entrée ; une unité de traitement d'image pour effectuer un traitement d'image du signal d'image d'entrée, pour comparer le signal d'image d'entrée avec le signal d'image traité afin de confirmer un type de traitement d'image, pour obtenir des informations de restauration du signal d'image traité en fonction du type de traitement d'image confirmé, et pour effectuer un nouveau mappage du signal d'image traité en utilisant des informations de restauration pour réparer une erreur du signal d'image traité ; une unité de sortie pour fournir un signal d'image ayant l'erreur réparée.
본 발명은 영상 디스플레이 장치 및 그 제어 방법에 관한 것으로, 영상 신호 처리 과정에서의 비트 수의 확장없이 입력 영상의 비트 수 대비 복원 영상의 비트 수의 확장만으로 영상 신호의 양자화 에러를 복원하는데 목적이 있다. 이를 위해 본 발명에 따른 영상 디스플레이 장치는, 입력 영상 신호를 입력 받는 신호 입력부와; 상기 입력 영상 신호의 영상 처리를 수행하고, 상기 입력 영상 신호 및 처리된 영상 신호의 비교를 통해 영상 처리 종류를 확인하고 상기 확인된 영상 처리 종류에 따라 상기 처리 영상 신호의 복원 정보를 획득하며, 상기 복원 정보를 이용하여 상기 처리 영상 신호의 리맵핑을 수행함으로써 상기 처리 영상 신호의 에러를 복원하는 영상 신호 처리부와; 상기 에러가 복원된 영상 신호를 출력하는 출력부를 포함한다. |
