Abstract
The invention provides an electronic apparatus. In one embodiment, the electronic apparatus comprises a video camera, a video processing module, an array microphone, and an audio processing module. The video camera adjusts a focal length according to a zoom-in/out control signal and captures an image of a plurality of target objects according to the focal length to generate a raw video signal. The video processing module generates the zoom-in/out control signal to adjust the focal length of the video camera. The array microphone comprises a plurality of microphones converting sounds of the target objects into a plurality of raw audio signals. The audio processing module adjusts a beamwidth for beamforming according to the zoom-in/out control signal, and performs a beamforming process according to the beamwidth on the raw audio signals to generate a first audio signal comprising mainly voice components of the target objects.
