The invention discloses a method for automatically regulating the Camera frame rate of a mobile terminal and the mobile terminal. The method comprises the following steps: setting a first threshold and a second threshold, comparing a current frame image and an adjacent previous frame image, acquiring a pixel difference quantity, recording the pixel difference quantity, judging whether the pixel difference quantity between any two adjacent images in a time interval before current time is smaller than the first threshold or not when the pixel difference quantity is smaller than the first threshold, and if so, setting the frame rate of a Camera output image as a first frame rate; and when the pixel difference quantity is greater than the second threshold, setting the frame rate of the Camera output image as a second frame rate. According to the mobile terminal disclosed by the invention, a Camera is in a static state if the pixel difference quantity within a certain time interval is smaller than the first threshold, and the frame rate of the Camera output image is set as the first frame rate, so that energy is saved for the mobile terminal. If the pixel difference quantity is greater than the second threshold, the Camera is in a shooting state, and the frame rate of the Camera output image is set as the second frame rate, so that the frame rate of the output image is reduced, and energy is saved for the mobile terminal.
