vid·i·con

 (vĭd′ĭ-kŏn′)
n.
An electron tube formerly used in video cameras to capture images by scanning a photoconductive surface with an electron beam. They generally provided higher resolution images than the orthicons.

vidicon

(ˈvɪdɪˌkɒn)
n
(Broadcasting) a small television camera tube, used in closed-circuit television and outside broadcasts, in which incident light forms an electric charge pattern on a photoconductive surface. Scanning by a low-velocity electron beam discharges the surface, producing a current in an adjacent conducting layer. See also Plumbicon
[C20: from vid(eo) + icon(oscope)]

vid•i•con

(ˈvɪd ɪˌkɒn)

n.
(in a television camera) an image-forming tube that operates on photoconductive principles: standard in most tube-type cameras.
[1945–50; vid (eo) + icon (oscope)]
