We have proposed so far a blood flow parameter that visualizes change in blood flow with the frame rate of imaging device employed, and have performed blood flow visualization on human fingers and arms. However, the present parameter required a long time in image processing for calculating itself. In the present study, we introduced an event-based vision camera that enabled us to capture changes in brightness as events and to output them independently and asynchronously for each pixel, and confirmed its availability for hemodynamic analysis by experiments performed for a flow model and human wrists and fingers.
