In this research, we investigated the method to detect depth and relative velocity of objects by using stereoscopic-camera images for the implementation of real-time image processing system. First, we proposed the method of estimating depth and relative velocity by using the amount of focus blur and disparity information when the focus positions of two cameras were set to be different. According to the result of simulation, the depth and relative speed were estimated reasonably. In addition, we composed a prototype system for the real-time image processing. The system consisted of CMOS image sensors designed for multiple-camera system, an FPGA, a PC, and other devices.
