The first Emmy statuettes were awarded in 1949 . The name was loosely adapted from Immy, the nickname for a piece of television equipment then in use, the image orthicon camera.

Image orthicons were used extensively in the early color television cameras, where the increased sensitivity of the tube was essential to overcome their very inefficient optical system of the other parts of the camera.
23.
An image orthicon camera can take television pictures by candlelight because of the more ordered light-sensitive area and the presence of an electron multiplier at the base of the tube, which operated as a high-efficiency amplifier.

The 1960s productions used Marconi image orthicon video cameras, which have a characteristic white " glow " around black objects ( and a corresponding black glow around white objects ), which was a defect of the pickup.

An image splitter was used in the TK-40 / 41 to direct the incoming light into three image orthicon tubes ( specially designed cathode ray tubes ) for recording moving pictures in the red, green, and blue component colors.
26.
While the iconoscope and the intermediate orthicon used capacitance between a multitude of small but discrete light sensitive collectors and an isolated signal plate for reading video information, the image orthicon employed direct charge readings from a continuous " electronically charged " collector.

This experimental camera had been inspired by RCA's new four tube camera, the TK42, and used the same tube arrangement, i . e . a 4?inch image Orthicon tube in the luminance channel and three 1 Vidicon tubes in the colour channels.
28.
The pictures from early Plumbicon cameras were susceptible to comet tails and blooming and, although these effects had not been a major concern in the previous generation of cameras, which employed vidicon or image orthicon tubes, they were an annoying feature of Plumbicon tubes.
29.
In the mid-1960s, Producer / entrepreneur H . William " Bill " Sargent, Jr . used conventional analog Image Orthicon video camera tube units, shooting in the B & W 819-line interlaced 25fps French video standard, using modified high-band quadruplex VTRs to record the signal.
30.
Following their visit, EMI quickly made an experimental 4-tube camera by cobbling together parts from an EMI Type 203 image orthicon studio camera with parts from an EMI Type 204 three-vidicon industrial colour camera This camera was demonstrated to the BBC and received a lukewarm reception there.
