| Abstract: | A method of microscope auto-focus is proposed based on the video signal processing for simulated image. The video signals from the directly intercepted image are real-time processed, by which the focus determination is conducted, and auto-focus is thus achieved. Also presented in this paper is the criterion function given by the sum. of the absolute values of voltage difference in the video signal. This method has a few advantages such as low power consumption and time-saving. Some technical points are made regarding the proposed method, along with the experimental results provided. |
