This paper presents an approach to detect skin with taking 16 by 16 pixels as the unit for videos that use Local Pixel Wise Skin Detection algorithm, named LPSD. It reliably recognizes and marks skin for each 16 by 16 pixels in the video, based on Field-Programmable Gate Array(FPGA). A special memory and two special counters reduces storage resource utilization caused by the restore all pixels information in 16 by 16 area. The algorithm could mark the skin area pixel by pixel without restoring 16 by 16 pixels each time. For the VGA standard image, 640 by 480 pixels, this algorithm uses 167,744 memory bits totally.
