An image capture system includes: a pan-tilt head with a driving-and-supporting mechanism; an image capture module including at least two image capture devices fixed on the driving-and-supporting mechanism and arranged side by side in a horizontal direction or a vertical direction; a distance obtaining module configured to obtain a distance between a to-be-captured object and the image capture module; a processor configured to calculate a width P of the to-be-captured object which is capable of being currently captured by one of the image capture devices based on the distance L and a visual angle of the image capture device in the horizontal direction or the vertical direction, and calculate a relative rotation angle of the image capture devices in the horizontal direction or the vertical direction based on the width; and a controller configured to control the image capture device to rotate based on the relative rotation angle.
