Special Optical Elements

Canon has always made an effort to research special optical elements
since our beginnings in this industry with the goal of minimizing
chromatic aberration. These efforts have included an artificial element,
"Fluorite", with extraordinary dispersion characteristics and the newly
developed"Hi-UD"(high index ultra low dispersion) glass. Canon has
succeeded in the practical use of special elements along with advanced
design techniques like "separate achromatism". Canon TV zoom lenses
carry a "Green Ring" on the focus barrel, a symbol of our high quality.
Canon has developed a break through in optical design technology
known as the "Power Optical System" whose heart is the "X-Element".
By using the "X-Element" to its maximum power in the specially
designed optical layout, higher specifications and quality can be
achieved in smaller and lighter lenses. The lenses designed using the
"Power Optical System" are known as the "XS-series".

All lenses are equipped with an informational display and Digital Function Selector, an X-Y axis switch, so that the user can customize the
enhanced digital functions much more easily and precisely. This new design enables the user to fully bring out the digital functions.

Aberration Correction for HDTV Lenses

The pixel size is about half in the HDTV system,
and therefore the spread of a point image caused
by a spherical aberration, coma, etc. should be
diminished to about half. Even if the image is
slightly out of focus, MTF is greatly influenced.
The graph 1 shows how MTF varies when the
focus changes. Canon HDxs series lenses employ
the HD version of the Power Optical System,
which incorporates the X-Element. HDxs greatly
contributes to correcting and minimizing these
aberrations at the same time, maintaining high
MTF throughout the edge of the picture (graph 2).

By memorizing any two focal lengths, the Digital Drive
can automatically "shuttle" between the two points, moving
in either direction.

Shuttle Shot

Canon has always developed new technology with four basic philosophies, "High Quality of
Picture", "Ease of Operation", "High Specification" and "Minimize Environmental Impact".
Canon's HDTV lenses are, so to speak, a compilation of our basic philosophies. Canon is the
only manufacturer to offer a complete line of HDTV lenses to match our customers
requirements. Complete "Customer Satisfaction" is our goal.

Overall Comparison Between HDTV and SDTV

Overall Comparison Between HDTV and SDTV

Main Featur

Main Featureses

Whereas one frame of the conventional SDTV (ie NTSC) system consists of 480 scanning lines, the
number of scanning lines is more than 1.5 times that for the HDTV system. Furthermore the density
of the scanning lines are even higher because the HDTV system has an aspect ratio of 16:9, which is
wider and shorter in height than that of the normal SDTV (4:3 aspect ratio) system. The spatial
frequency required for the HDTV system is about twice that required for the NTSC system. Overall,
the resolution of the HDTV system is about twice that of the NTSC system and therefore, the lens
requires much higher performance than the conventional lenses.

An angle of view can be preset in either of two memories
and the lens will zoom to that position by pushing a simple
button. During a performance, framing preset will reproduce
the zoom position decided upon at the rehearsal. It's easy to
repeat the same zoom as often as you like at the highest
speed or in a preset zoom speed.

Enhanced Optical Technology

Enhanced Digital Drive

Canon proudly offers our Broadcasting Lens Technology, . The technology consists of two meanings that start with the letter
"e". One is the "ecological design", a design harmless to the environment. The other is the "enhanced digital" technology which improves the
performance of the digital drive unit. Of course the new technology inherits all the advantages of its predecessor, the HDxs technology,
which includes the advanced optical design concept, based on the X-Element technology.

Ecological Design

Ecological Design

Rotary Encoder

Canon offers a complete series of eHDxs
lenses, which are equipped with an enhanced
digital drive unit. Conventional potentiometers
are analog positional sensors capable of only
8-10 bit equivalent resolution. Thus virtual ENG
studio systems called for an optional Encoder
Unit to be put on the zoom and focus ring of
the lens. With the introduction of 16 bit
resolution Rotary Encoder Devices built into
the new enhanced digital drive unit, the lens
can simply be integrated into a virtual digital
studio system without any additions. The
encoders also enable superior precise control.
The zoom servo provides a dynamic range of

0.5 sec. to over a 5 min. super slow zoom.
Repeatability in focus and iris control are also
much more precise. Canon's unique
technology has made the Encoder Device
surprisingly small to be installed in the existing
drive unit without changes in size or weight.

Ecological Design

It is Canon's policy not to pollute the earth and
the eHDxs series have avoided using any
materials or substances that could pollute the
environment.
