The invention discloses an electronic immediate imaging system. The electronic immediate imaging system includes an image capturing module and a display module. The image capturing module includes an image capturing/processing unit, a multiplexer, and an image converting/transmitting unit. The image capturing/processing unit is used for capturing an image to generate a first image signal related to the image. The multiplexer is coupled to the image capturing/processing unit and for receiving and converting the first image signal to a second image signal. The image converting/transmitting unit, coupled to the multiplexer, is for converting the second image signal to a third image signal and transmitting the third image signal out. The display module includes a first image receiver and a display unit. The first image receiver is coupled to the image converting/transmitting unit and for receiving the third image signal. The display unit is used for displaying the image according to the third image signal.
