Definitions
- the adjusted image data is displayed in the display area.
- the step of displaying the adjusted image data in the display area includes:
- a determining module configured to determine whether the image data to be processed matches the display area; if not, triggering the second acquiring module;
- the determining module is specifically configured to:
- the historical data boundary is: a historical video before the video signal to be processed The boundary between the image data in the signal and its blanking data;
- the searching submodule is specifically configured to:
- S102 may include: determining, according to the recorded matching result of the historical image data before the image data to be processed and the display area, whether the image data to be processed matches the display area.
- the video signal acquired in S101 may be a current frame video signal, where the current frame image data and its corresponding blanking data are included.
- the matching result of the history frame image data and the display area can be recorded. It can be understood that, for the same video stream, the matching result of the image data of each frame and the display area is generally the same. Therefore, it can be determined whether only one frame or part of the frame image data in the video stream matches the display area, and records Match results, other frames refer to the recorded matching results.
- the process of processing one frame or partial frame image data in the video stream may be similar to the process of processing the image data to be processed in the above content.
- other methods may be employed. For example, it may be detected whether there is an abnormality in the data displayed in the display area, and if so, the matching result of the recorded history image data and the display area does not match.
- the pixel value of the blanking data is not limited to 255, and may be any value greater than the maximum value in the preset threshold range, such as any value between 236 and 255.
- finding the target pixel point that is, finding the pixel point whose pixel value is between 236 and 255, the pixel point found can be understood as blanking data, and the blanking data is found, and the blanking data can be determined.
- the boundary between image data that is, finding the pixel point whose pixel value is between 236 and 255.
- S105 Extract valid image data according to the image boundary, and display the valid image data.
- the resolution of the adjusted image data is adjusted to be equal to the preset resolution, and the image data after the resolution is adjusted is displayed in the display area.

Abstract
Selon certains modes de réalisation, la présente invention concerne un procédé et un appareil d'affichage d'image, le procédé consistant à : acquérir un signal vidéo à traiter, le signal vidéo à traiter comprenant des données d'image à traiter et des données de suppression correspondant à celles-ci ; lorsque les données d'image à traiter ne correspondent pas à la zone d'affichage, acquérir la position des bords entre les données d'image à traiter et les données de suppression par rapport à la zone d'affichage ; sur la base de la position, régler les données d'image à traiter pour correspondre à la zone d'affichage ; et afficher les données d'image réglées dans la zone d'affichage. Les données d'image réglées correspondent à la zone d'affichage, améliorant ainsi les effets d'affichage d'image.
