A simple time-lapse cinematography device that provides useful insight for embryo quality scoring by series observation of embryos during culture was developed. The device consists of a microscope system, a PC controlled camera and an illumination system. All components are implemented in a waterproof enclosure to be operated inside a CO2 incubator. Operations for image capture including focus adjustment and illumination adjustment can be remotely performed using PC without removing embryos from the optimal gas and temperature conditions. Using this device, clear images including several embryos were captured and the cleavage timing of embryos can be exactly identified.
