Problems solved by technology
[0003] In summary, the problems in the prior art are: Although the fixed pure black opaque background can highlight the subtitles to the greatest extent, it blocks the video content, especially when the subtitles occupy a large space, this processing method greatly affects the experience of watching videos
[0004] The difficulty and significance of solving the above technical problems: The transparency of the background is the key to balance the clarity of subtitles and video occlusion: if the background is opaque, the subtitles will be the clearest, but the video will be completely blocked; if the background is fully transparent, although there is no occlusion to the video, affected by the color change of the video, the subtitles will be clear degree but cannot guarantee

Embodiment Construction
[0037] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0038] The background of the fixed subtitle is black, and the transparency of the black background is dynamically adjusted in real time according to the color change of the video screen in the area where the subtitle is located, so as to reduce the occlusion of the video as much as possible while ensuring that the subtitle is clear and readable. Here, the technology of dynamically adjusting the transparency of the black background in real time according to the change of the color of the video image in the area where the subtitles are located is called environment perception technology. It is the core of the present inventio...

The invention discloses a subtitle background processing method based on environmental perception technology and a displayer, belonging to the technical field of preparing explanatory subtitles. According to the subtitle background processing method based on the environmental perception technology, the subtitle background is fixed to be black, and the transparency of the black background is adjusted in real time according to the changes of the video frame color in the subtitle area. The subtitle background processing method based on the environmental perception technology comprises the following steps: calculating to obtain the mean value of the area pixels for the subtitle area A; calculating the image color complexity PA of the area A; and calculating to obtain the subtitle background transparency Talpha. The invention dynamically adjusts the transparency of the subtitle background by means of the environmental perception technology; and the shadow of the subtitle background on the video can be reduced to the maximum under the condition that the subtitle is clear; therefore, the video viewing experience is improved.
Description
technical field [0001] The invention belongs to the technical field of preparing and explaining subtitles, in particular to a subtitle background processing method based on environment perception technology and a display. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: With the rapid growth of Internet bandwidth and the continuous reduction of costs, online video has become the main way for users to watch videos. In order to help users better understand the content of the video, video producers usually superimpose subtitles on the video. Due to the rich color of the video screen and the rapid change, in order to ensure that the subtitles are clearly visible, there are usually the following two subtitle processing methods: 1. The subtitle font color is white, and a black shadow is added to the subtitle at the same time; 2. The subtitle font color is white, and the shadow color is white. Black, and add a black...
