The invention provides a light control method and device of a vehicle-mounted entertainment system and the vehicle-mounted entertainment system. The light control method of the vehicle-mounted entertainment system comprises the following steps: acquiring an audio signal in a vehicle; sampling the audio signal according to a preset time interval to obtain sampling data; extracting audio features ofthe sampling data, the audio features which comprises the amplitude and/or frequency of the audio signal; and controlling the light of the atmosphere lamp according to the audio characteristics. Thesampling data is obtained by sampling the audio signal, so that the processing amount of the audio data is reduced, and the audio data processing efficiency is improved. Moreover, the audio characteristics of the sampling data are extracted, and the light of the atmosphere lamp is controlled according to the audio characteristics, so that the light of the atmosphere lamp is changed along with thechange of the audio characteristics of the audio signals, a good KTV atmosphere is created, and the user experience is improved.
本发明提供了一种车载娱乐系统的灯光控制方法、装置及车载娱乐系统。该车载娱乐系统的灯光控制方法包括获取车内的音频信号;对音频信号按照预设时间间隔进行采样得到采样数据;提取采样数据的音频特征,其中,音频特征包括音频信号的振幅和/或频率;依据音频特征控制氛围灯的灯光。通过对音频信号进行采样处理得到采样数据,减少了音频数据的处理量,提高了音频数据处理效率。并且,通过提取述采样数据的音频特征,并依据音频特征控制氛围灯的灯光,使氛围灯的灯光随着音频信号的音频特征的变化而变化,营造良好的KTV氛围,提高了用户的体验。
