The invention discloses a method and a system for determining the open flash point by using a CCD mode. The method comprises: (1) acquiring an original image with no ignition and no flash fire; (2) heating the oil sample in a test oil cup; (3) acquiring real-time images during the heating process; (4) comparing the real-time images to the original image, and determining whether flash fire occurs; (5) repeatedly performing the steps (2)-(4) if the flash fire does not occur; and (6) recording the temperature of the oil sample as the flash point if the flash fire occurs. The system comprises a heating device, a CCD acquisition device, a temperature acquisition device, and a processor. According to the present invention, whether the flash fire occurs is automatically recognized by using the CCD technology, such that the labor force is liberated, the labor cost is saved, and the eyes of operators are protected; 2, the feature of the ignition head area image is eliminated, such that the blue light interference of t
