MOBILE TERMINAL AND IMAGE PROCESSING METHOD THEREOF

摘要

The present disclosure discloses an image processing method of a mobile terminal, and a mobile terminal. To process an image, an audio signal is collected using a sensor of the mobile terminal. Air-blowing signal intensity is acquired by performing a windowed fast Fourier transform (FFT) on the audio signal to obtain a frequency domain signal of the audio signal. The frequency domain signal of the audio signal is divided into at least one time-slice frequency domain signal. It is then identified whether the audio signal is an air-blowing signal according to the at least one time-slice frequency domain signal and a preset property of the air-blowing signal. The air-blowing signal intensity is acquired according to the at least one time-slice frequency domain signal when the audio signal is identified as an air-blowing signal. An image is acquired according to the air-blowing signal intensity. In this manner, the image processing method using the air-blowing signal intensity may provide improved processing efficiency and simplified operation.
