System and method of converting monitored physiological signal

The present invention provides a monitored physiological signal conversion system with functions of setting, recognizing and converting an interested block on the image including physiological signals. The system includes an image input port, an image capture module, a monitored physiological signal image conversion module, a monitored physiological signal output module and a memory module. Moreover, this invention provides a way of setting the coordinates of the interested block to identify the location of the interested block. After that, the monitored physiological signal image of the interested block will be recognized and converted into a text file, as well as output in the form of numbers or text. Hence, the monitored physiological signals in detection is immediately processed and provided in real-time, thereby achieving the purpose of improving the quality of medical services.
