Time-of-flight depth sensor provides faster and easier way to 3D scene capturing and reconstruction. The depth sensor, however, suffers from motion blur caused by any movement of camera or objects. In this manuscript, we propose a novel depth motion blur pixel detection and elimination method that can be implemented on any ToF depth sensor with light memory and computation resources. We propose a blur detection method using the relations of electric charge amount. It detects blur pixel at each depth value calculation step only by checking the four electric charge values by four internal control signals. Once we detect blur pixels, their depth values are replaced by any closest normal pixel values. With this method, we eliminate motion blur before we build the depth image with only few more calculations and memory addition.
