Automatic control system for image and sound

Abstract

The present invention provides an automatic audio/video control system designed to control an audio/video output device; the audio/video output device can at least produce a video source or audio source; the automatic audio/video control system comprises an ambient sensor designed to sense the intensity of signals from the video/audio source and output audio/video sensing signals, and an audio/video analyzer, which is electrically connected to the ambient sensor and the audio/video output device and designed to output audio/video control signals according to the audio/video sensing signals to regulate the intensity of the audio/video source. The control system sense variations of the ambient environment by means of the ambient sensor, analyzes and compares with the internal signals in the system, and output appropriate feedback signals to regulate the intensity of the audio/video source of the audio/video output device automatically, so as to attain best audio/video effect. The control system meets people's demand for easy use, environmental compatibility, and individualization for electronic products.

Description

Technical field [0001] The invention relates to an automatic control system, in particular to an audio-visual automatic control system which can automatically adjust the output sound source or light source according to the change of the environment. Background technique [0002] With the rapid development of society, the impact of environmental noise on people's life and learning is also increasing day by day, and environmental changes also bring inconvenience to people's use of electronic products. For example, when using a computer to play music in a noisy environment, the user must manually adjust the output volume to a higher level in order to hear clearly. However, when playing music in the dead of night, in order not to affect the rest of others around, the output volume must be manually adjusted to a lower level, so as not to cause environmental pollution. In the same way, when the light in the external environment is too strong or too weak, in order to prevent the screen ...

Problems solved by technology

Due to the frequent changes in the environment, this manual adjustment procedure is cumbersome, and repeated manual operations bring inconvenience to the user, and because people have different audiovisual and tactile discrimination capabilities for environmental changes, people with poor resolution often ignore it. Make appropriate adjustments to electronic products, on the one hand, it may cause another source of noise pollution due to excessive playback sound, on the other hand, it may also cause discomfort to the eyes due to failure to adjust the output light source intensity of electronic products in time Visual effects, over time, leading to loss of vision
