Research On Comfortable Display Of Stereoscopic Subtitles

With the continuous development of three-dimensional display technology,threedimensional display technology products become information technology development trends and trends.But the 3D display technology to bring people visual impact at the same time,three-dimensional title display quality and visual comfort has not been satisfactory.As one of the ways to obtain video information,comfortable subtitle display can provide a good 3D experience to the viewer,so the study of the threedimensional subtitles is the key to the development of stereoscopic display technology.In this paper,the color coordination between subtitle and background is studied,RGB component of stereo content is selected as the three inputs of fuzzy control,and the input is transformed into the domain of fuzzy control.Fuzzy rules are set according to the theory of color coordination and expert experience.Fuzzy domain instead of the difficult to establish accurate mathematical model to solve the three-dimensional content of the background color is complex and difficult to set its coordination with the subtitles color problem;by adding the smoothing module on the fuzzy controller output smoothing,The output fluctuation of the fuzzy controller is too large to cause the incongruity problem.Finally,the color subtitles are coordinated with the background color,which resolves the color conflict between the subtitle color and the stereoscopic content to some extent,and improves the stereoscopic content viewing comfort.In this paper,we study the rolling speed of scrolling subtitles,design EEG experiment to record people's EEG signals at different scrolling speed of threedimensional subtitles.Through analyzing EEG signal frequency domain,we find EEG features which can characterize the comfort of subtitles.The design of 3D video scrolling subtitle provides experimental basis.
