Power source is usually constrained in the wild areas. Thus, in this paper, we developed a low power-consumption image transmission system (called energy-efficient visual eyes system) by integrating a MSP430 micro controller, FPGA circuit, a solar powered battery, a digital camera, and a GPRS (General Packet Radio Service) modem. In order to make a monitoring system suitable for circumstances of wild islands, the proposed system is designed with a packet transmitting strategy capable of enhancing pixel validity while effectively decreasing power consumption. Practically, the proposed system is deployed on a wild island in Taiwan near East China Sea, where is a habitat for migrant seabirds. The experimental results show that the system design is feasible to ecological monitoring and able to effectively maintain the completeness of images with energy efficiency. © 2011 IEEE.[SDGs]SDG7East China Sea; Ecological monitoring; Energy efficient; FPGA circuits; GPRS (general packet radio service); Image transmission systems; In-situ; Monitoring system; Power sources; Real-time surveillance; Solar-powered; Visual monitoring; wild island; wireless communication; Animals; Digital radio; Ecology; Electric power transmission; Emergency traffic control; Image communication systems; Low power electronics; Monitoring; Radio broadcasting; Radio transmission; Real time systems; Solar energy; Systems analysis; Wireless telecommunication systems; Energy efficiencyconference paper10.1109/HPCC.2011.124
