The Eye’s Superior Technology
Compared with the eye, cameras possess a very primitive structure.
Visual images are many times more precise than those obtainable with
even the most highly developed camera. As a result, images perceived by
the eye are of much higher quality than those provided by any man-made
equipment.
This whole idea can be better grasped if we examine the principles of
a TV camera, which operates by transmitting numerous dots of light.
During broadcast, a scanning procedure is applied, and the object before
the camera is thus divided into a specific number of lines. A photocell
lamp scans all the dots in each line consecutively, from left to right.
Having finished scanning one line, it moves on to the next, and the
process continues. The light values of each dot are analyzed, and the re-
sulting signal is emitted. This photocell scans 625 or 819 lines in one-twen-
ty fifth of a second. When one entire image is complete, a new one is
transmitted. In this way the quantity of signals emitted is very high, all
created at a dazzling speed.
The eye’s mechanism is much
more functional. One can
clearly understand the as-
tonishing perfection of
its structure when
one considers that it
never needs to re-
pair or replace any
parts.
