The physical concept allowing the reproduction of colour is metamerism: the effect of any colour on the human eye can be reproduced by combining the effects of three other colours, known as primaries. Three simple colours can constitute primaries if none can be achieved with a combination of the other two. Red plus Blue Green plus Red plus Blue In ...
The triple nature of colour derives from a characteristic of human physiology, since colour vision depends on the absorption of light, by the retina of the eye, by three different photosensitive pigments. The practical experience showing that three colours can, when brought together, equal a fourth, indicates that this principle can serve as the ba...
The values of the brightness or colour of picture elements along a television line can be represented by a series of numbers. If these are expressed in base 2, each value can be transformed into a sequence of electrical pulses. The operation which converts from the "analogue" world to the "digital" world comprises two stages: sampling in which th...

It is the continual development of this technology and the associated facilities which has enabled producers and directors to overcome one after the other the limitations of the tools at their disposal and to offer an ever-greater challenge to the ingenuity of Man's imagination.

The operation of a zoom lens is based on a simple principle of optical science which determines that the smaller the focal length, the wider the angle of view. In other words, if the focal length is made to change smoothly, a progressive variation can be made from "wide-angle" to "tele photo " characteristics. The zoom has at least two groups of le...

In camera telecines [1], each film frame is focused onto the target of a television camera, via an appropriate lens system. In flying spot telecines [2], a light beam, produced on the screen of a cathode-ray tube, scan...
The design of digital memories for recording television pictures has led to the development of image processing The computer graphics artist at work systems offering far greater scope than conventional optical or electronic special effects techniques. The image, translated into a series of separate elements, can be reconfigured and, for example, di...
Research is being pursued in several domains with a view to further improving the visual impression of electonic images.
No satisfactory method has yet been found for giving an impression of relief in television (3-D). One of the main problems is that systems relying on colour separation create an artificial impression. Researchers are today investigating techniques using neutral polarized glasses. With all these systems, viewers would be required to wear glasses. To...
