Problems solved by technology

[0008] 1. As one of the important indicators of subtitle rendering, the effect of edge anti-aliasing is not ideal, and it cannot even reach a practical level
This is because the existing subtitle system completely relies on the image processing method of the current pixel space when performing anti-aliasing processing. Without the participation of subtitle geometric vector information, sub-pixel-based processing cannot be realized.
This makes the final rendering effect of the existing subtitle system have a relatively obvious edge aliasing effect, which affects the effect of the subtitle display
[0009] 2. When a subti

Embodiment Construction

[0062] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0063] In the current subtitle system used for TV program production, there are generally low rendering efficiency, edge aliasing effect, blurred and unclear small characters, uneven stroke thickness of characters, unreal gradient effect, and unrealistic rendering effects of polygons and shadows. A series of technical and application problems such as artistic word effects can be solved by converting the vector information of the subtitle object into a pixel mask matrix based on contour lines, and then rendering subtitles on this basis. This technology is called a subtitle rendering method based on a closed-circle domain of a curve outline and a pixel mask matrix (for details, please refer to the patent applied for at the same time).

[0064] The key step of the above method is firstly the generation of finite closed loop domains. A finite cl...

Abstract

The invention relates to the subtitle rendering technology of TV programming field, in particular to a subtitle rendering method based on a pixel space mask matrix model. The method confirms the attribute value of a pixel space mask matrix, carries out texture mapping, shape gradient radial color filling and anti-aliasing processing on subtitle object by establishing the pixel space mask matrix, a texture image matrix and a shape gradient color array according to the polygon vector outline of the subtitle object. The invention makes the subtitle system have the advantages of excellent practicality, general applicability, complete and expansible function and programming and broadcasting timeliness, consequently the increasing requirement of a TV program programming and broadcasting mechanism over subtitle quality, subtitle effect and the like can be met.

Description

technical field [0001] The invention relates to a subtitle rendering technology in the field of television program production, in particular to a subtitle rendering method based on a pixel space mask matrix model. Background technique [0002] Because TV subtitles have an independent ideographic function, as a necessary TV program element, TV subtitles are an important display form of TV graphics. With the subdivision of TV channels and program content, the division of labor of various departments has become more specialized. For the production of different types of programs, it is difficult to meet the requirements with a single type of subtitle system. In addition, the increasing diversity of TV programs and the continuous improvement of TV viewers' appreciation and appreciation level also require that the application mode of TV subtitles must develop in the direction of diversity. [0003] From a broad point of view, the subtitle objects handled by TV subtitles can be di...
