"The first KH-11 KENNEN reconnaissance satellite equipped with charge-coupled device array (800 × 800 pixels)[citation needed] technology for imaging was launched in December 1976.[14] Under the leadership of Kazuo Iwama, Sony started a large development effort on CCDs involving a significant investment. Eventually, Sony managed to mass-produce CCDs for their camcorders. Before this happened, Iwama died in August 1982. Subsequently, a CCD chip was placed on his tombstone to acknowledge his contribution.[15] The first mass-produced consumer CCD video camera, the CCD-G5, was released by Sony in 1983, based on a prototype developed by Yoshiaki Hagiwara in 1981.[16]
