In the case of treatment that refractory ulcer induced Peripheral Arterial Disease (PAD), it is very important that the 2D tissue circulation area screening before surgical treatment, but there is no wellestablished and easy evaluation method. So that we developed image processing system using Red brightness parameter of RGB gradation of video image which recorded skin surface of lower extremity, and evaluated with clip and de-clip procedure in human toe. Measurement hardware is handy HD video camera which were commercially available not as expensive diagnostic devices. We confirmed that processed images of color change on skin surface color change during clip and de-clip lower extremity procedure, indicated the 2D pattern of hemodynamics change on toe.
