A method for automatically rapidly analyzing biological cells includes continuously capturing a plurality of image frames of a suspension including a plurality of biological cells according to a predetermined time interval within a predetermined time using a low-magnification optical image amplification device of a image capture device; transmitting each of the plurality of image frames to an operation processing device; the operation processing device utilizing an image identification technology to detect a number of the plurality of biological cells in an image frame and a static data of each biological cell of the plurality of biological cells according to at least one parameter; and the operation processing device generating a dynamic data of each biological cell in the image frame according to the static data of each biological cell in the image frame and the static data of each biological cell of a previous image frame.
