Abstract: Disclosed is a microscope system for observation and display of microcirculation of blood at multiple body areas. The system includes an optical microscope and a display system. The optical microscope includes an electronic flash light and a scotopic detector to take instantaneous photos of images of microcirculation of blood of an observed object. An analog-to-digital conversion circuit converts video simulated signal into digital image signals that can be processed by a computer and are stored in an image memory. In an image card, the image signals in the image memory are stacked to digital graph signals stored in a graph memory, the resultant signals are converted into video simulated signals by a digital-analog conversion circuit and are output to a monitor, so that images of microcirculation of blood are displayed on the monitor.
