Method and device for controlling subtitle applied to display apparatus

摘要

A method for controlling subtitles applied to a display apparatus is provided. The method is capable of dynamically adjusting a subtitle of an original image. The original image includes a right-eye frame and a left-eye frame. The right-eye frame includes right-eye subtitle information, and the left-eye frame includes left-eye subtitle information. The method includes the steps of: determining an adjusted subtitle display mode; determining a shift distance of the right-eye subtitle information and the left-eye subtitle information; and adjusting the shift distance according to the adjusted subtitle display mode or a given 3D depth, such that an adjusted subtitle presented by the right-eye frame and the left-eye frame shows an adjusted subtitle 3D depth. The adjusted subtitle display mode includes a static display mode and a dynamic 3D display mode.

主权项

1. A subtitle control method, applicable to a display apparatus, for dynamically adjusting a subtitle of an original image, the original image comprising a right-eye frame and a left-eye frame, the right-eye frame comprising right-eye subtitle information, the left-eye frame comprising left-eye subtitle information, the method comprising:
selecting an adjusted subtitle display mode; determining a shift distance of the right-eye subtitle information and the left-eye subtitle information; selectively adjusting the shift distance according to the adjusted subtitle display mode and a selected 3D depth, such that an adjusted subtitle presented by the right-eye frame and the left-eye frame shows an adjusted subtitle 3D depth; and determining an original subtitle display mode, comprising:
comparing the shift distance of the right-eye subtitle information and the left-eye subtitle information;determining the original subtitle display mode as a static display mode when the shift distance is substantially stable; and determining the original subtitle display mode as a dynamic 3D display mode when the shift distance changes with time; wherein, the adjusted subtitle display mode comprises a static display mode and a dynamic 3D display mode, and when the adjusted subtitle display mode is different from the original subtitle display mode, the selected 3D depth is generated according to the adjusted subtitle display mode to accordingly adjust the shift distance.
