Technical Field

Background

In the data source processing, when the aspect ratio of the data source to be processed is inconsistent with the aspect ratio of the data source display area, black borders are formed above, below, or on the left and right of the data source display area (i.e., the area not filled with the data source) when the data source is played, which affects the viewing experience of the user on the data source. The type of data source may be video or picture.

In the related art, when the width and height of a data source are scaled to enable partial content of the data source to fully occupy a data source display area, the portion, outside the data source display area, of the scaled data source is cut, and the processed data source is rendered and displayed in the data source display area, so that the problem of black edges in the data source display area is solved.
