Video acquisition method and electronic apparatus

A video acquisition method includes calling a first image collection device (camera) and a sound collection device based on a camera mode; collecting first image data of a first space in real-time through the first image collection device; collecting audio data covering a spatial environment including the first space in real-time through the sound collection device; processing the audio data in real-time based on an audio processing engine, in response to determining, through the audio processing engine, that the audio data indicates that a target sound source exists in a second space different from the first space; calling a second image collection device, and collecting second image data of the second space in real-time through the second image collection device. The method allows for automatic switching between, for example, front and rear cameras on a phone based on the sound being recorded.
