4. COMMENTARY

4.1 External appearance design (The LV-X1 is different from the LV-S1
only in product logos.)
External Styling
The entire body has a refined and lively three-dimensional form that suits a video
equipment to make it less conspicuous and give a sophisticated and friendly
impression in the environment where it is installed. Although it provides high
brightness and high quality, it is designed to save space to reduce restrictions on the
installation place. It can be used in various places from bright offices with external
light to home theaters.
Details
The exhaust port from which heat and noise are produced is laid out on the front
panel that is far from the operator. The port is equipped with a cover to give an
impression of stylish precision.
The rear design is simplified so that the user can concentrate on the projected image.
The operation panel is finished so that the focus ring and zoom lever show the
Canon's brand image. The operation panel on the top is tilted to the rear to improve
operability and buttons are laid out around the cursor keys so that they can be
operated by touching with a hand without looking at them.
Coloring
This projectors has two basic colors of satin metallic silver and glacial blue and has a
clear water blue area as an accent to give an impression of high quality and lightness.
It is finished so that it matches offices (conference), shops (promotion) and homes (AV
system). Stain and weatherability have been considered so that it can be used for a
long time. Its worth can be discerned when it is used for an extended period of time.
Ecology
The number of parts is reduced, and polyvinyl chloride and lead are not used as
materials. Materials are shown on all external parts.
All the screws have the same size so that they can be removed with a single
screwdriver.

4.2 Optical System

LV-X1
A newly-developed high-refractivity 4P color synthesis prism is adopted to minimize
deterioration of picture quality due to the color synthesis prism. In addition, a large
aperture F1.6 zoom lens suitable for the LCD panel with a microlens is used to achieve
the highest brightness of 1100 ANSI lumen in the 0.7-inch class.
Cooling efficiency is improved greatly by using fluorite with high thermal conductivity
as two field lenses to escape the heat of the deflector.
A free curved surface mirror is used in the illumination relay optical system to reduce
weight, and a teletype illumination optical system is used to reduce the size markedly.
