We propose a method of detecting respiration curve for the Drowsiness Predicting system based on optical image information processing. It is well known that a falling sleep relate to respiration. This paper focus on a frequency and amplitude of respiration while driving to predict a moment of a falling sleep. Proposed system composed of video camera and image processing unit. Video camera capture time-series image while driving. Image processing unit calculate subtract images per any frame. The respiration ratio is extracted to analysis the time-series signal. In this paper, we have developed a test bed system, and evaluate our system in comparison with a medical device.
