In this paper, we propose a real-time object detection LSI for mobile videophone. The LSI achieves real-time processing speed by stereo vision algorithm using temporal data relationship between frames. The algorithm uses a last frame result to reduce the detection area and search range to the edge of the object and the background. We have designed object detection LSI by using this algorithm. The LSI can process QCIF stereo images 30 frames/sec and logic area is 15182 gates.
