1. FEATURES
1.1 Development objectives
This projector has been newly developed as a successor to the Canon Multimedia
Projector "LV-7535" as a "flagship model" to achieve the highest brightness in its class,
high quality and functions.
As the recent market trend shows that the brightness of the ultra-portable class (0.9")
of projectors is increasing greatly, higher functions and performance are being
demanded. Since they are used in various places, such as large conference rooms,
halls, and offices, they must have flexible functions.
The product has a Canon's unique power-driven Turbo Bright System that provides
the top-level brightness at its class and has the replacement lens system and power lens
shift mechanism that reflect the Canon's design concept to achieve both high quality
and installability. In addition, it has various interfaces to provide the features and
performance suitable as a flagship model with system scalability in mind.

1.2 Major Features
●New power-driven Turbo Bright System. Highest brightness of 3700 ANSI lumen in the
class
The projector achieves the highest brightness in its class with the Canon's original
Turbo Bright System and new optical design.
A remote control can be used to switch between Bright ON and OFF.
●XGA LCD panel with contrast ratio of 800:1
A high contrast of 800:1 is achieved by improving transmittance of the 1.3" LCD panel
with 1024 ×768 pixels and using a contrast improvement filter.
High-quality SXGA projection is provided by XGA real projection and digital
compression.
●Power-driven lens shift mechanism. Three types of optional replacement lenses
The power-driven lens shift mechanism can shift the projection screen position
vertically.
In addition to the standard lens, three types of optional replacement lenses (ultra wide
angle lens, wide angle zoom lens and long focus zoom lens) are available.
These functions can cope with various installation conditions, such as height and
distance, flexibly to provide high-quality projection all the time.
●Video mode selection function suitable for projection data
The optimum gradation can be reproduced according to projection data for PC input
and video input by switching between video modes: standard/high contrast for PC
input and standard/cinema.
●Clear PC image by DVI. High-quality video image by the progressive scan function
Supports digital interface (DVI) to reproduce clear PC images.
Uses progress scan to project higher-quality video and HDTV images.
●37dB silent design
The fan speed is optimized by detecting the inside temperature.
The noise is suppressed by reducing the unnecessary increase in fan speed.
●Extended Digital Keystone function, up to ±40 degrees
Smoothly corrects for "keystone" effect, giving a square image with up to 40 degrees

4. COMMENTARY
4.1 External appearance design
●External Styling
The entire body is designed with smooth curves and uses simple lines for the BRIGHT
indicator on the top and the infrared receiver on the front panel.
This gives an impression of a modern sophisticated office equipment suitable for the
flagship model of Canon new-generation projector.
●Coloring
The new-generation Canon projectors have two basic colors of satin metallic silver,
which evokes a sophisticated image, and glacial blue, which makes you feel at ease.
This projector has larger glacial blue areas than the other new models and the
operation keys and the Canon logo colored a glossy metallic color to give an
impression of a sophisticated office equipment.
In addition, its details have been designed carefully to make it worth the top model by
painting all screws silver, for example.
●Usability
The projector can be operated easily because of high visibility with larger letters with
high-contrast color printed on the operation panel and near connectors.
The lamp and lenses are designed as follows so that they can be easily replaced.
• The lens assembly can be accessed by removing two screws on the top and the
cover.
• The projector has a lamp replacement lid on the back. The lamp assembly can be
accessed by removing two screws from the lid..
4.2 Optical System
●The projection lenses have been newly designed and the LCD panel has been improved
to achieve high brightness and high contrast. In addition, the power-driven Turbo
Bright System has been built into the projector to realize the top-level brightness of
3700 ANSI lumen in its class..
●Large aperture zoom lens: f1.7
large aperture f1.7 projection lens is adopted. The optical system has 11 groups of 13
elements. The zoom has been designed so that four of six groups are moved to
minimize aberrations and improve illuminance ratio.
This product offers the highest brightness in its class and excellent resolution.
All lenses are made from lead-free glass
●LCD panel
The opening ratio of the LCD panel has been increased to improve transmittance and
the contrast improvement film has been modified to achieve the highest level of
contrast ratio of 800:1 (all white/all black).
Part 1: General Information
1-6

4.3 Turbo Bright System
This product has an additional function that electrically controls the Canon's original
Turbo Bright System, which enables switching brightness and color with a remote
control.
The highest brightness can be switched with the BRIGHT button, as follows:
BRIGHT ON: 3700 ANSI lumen ↔BRIGHT OFF: 3200 ANSI lumen
4.4 Video Input System
1) RGB input
●Analog or digital (DVI) input
Real XGA images can be projected with the 1.3" LCD panel with 1024 ×768 pixels.
High-quality SXGA images can also be projected using the digital compression
technology.
SXGA, XGA, SVGA and VGA signals are supported.
* SXGA is not supported for digital input.
●Multi scan system
The appropriate system mode is automatically selected by recognizing the horizontal
and vertical frequencies of video signals from a PC.
●Automatic PC adjustment function
Three items, i.e., the total number of dots in the horizontal direction of the screen,
tracking and screen position, can be automatically adjusted.
* Some PCs cannot adjust all these items completely. In this case, adjust them
manually.
* If a digital signal is input or the RGB, 720p, 1035i, 1080i50 or 1080i60 system
mode is selected, automatic adjustment does not work.
2) Component input
●Supports HDTV, DTV and DVD component input.
Supports 1080i, 1035i, 720p, 575p, 480p, 575i and 480i. (Automatic or manual)
Supports color difference signals (Y, Pb/Cb, Pr/Cr) input. Beautiful images are
reproduced with minimal blurring of color.
3) Composite input or S-Video input
●Color system
Supports many color systems: NTSC, PAL, SECAM, NTSC4.43, PAL-M and PAL-N.
Automatically detects color system, except PAL-M and PAL-N.
* The composite (video) input uses the same connector as used for the intensity
signal (Y) for component input.
Part 1: General Information
1-7

4.5 Image Control
●Digital keystone function
Smoothly corrects for "keystone" effect on the projection screen, giving a square image
with up to 40 degrees tilt.
●Digital zoom function
Digital zoom enlarges (or shrinks) any selected part of the presentation image (×1/4 to
×49).
●Image inversion function
Images are inverted horizontally on rear projection, and they are inverted horizontally
and vertically when the projector is suspended from the ceiling.
●Noise reduction function (video signal only)
Three-dimensional noise reduction is adopted. The signal-to-noise ratio is improved
without deteriorating resolution and color.
It is effective to old noisy video images. It can reduce roughness caused by noise.
4.6 Mechanism
●Power-driven lens shift mechanism.
Lens shift is carried out electrically from 1:1 to 2:0.
The power-driven lens shift mechanism can move the projection screen position
vertically and smoothly.
Fig. 1-2
When the lens is shifted to the maximum, the projection screen moves upwards by
approx. 50%. (The screen size is unchanged.)
The projector can be installed more flexibly by combining lens shift with replacement
lenses.
When the ratio is 1:1 When the lens shift is maximized
Part 1: General Information
1-8

Part 1: General Information
1-9
●Automatic fan control system
When the temperature sensor detects a low temperature, the fan speed is reduced
automatically to suppress fan noise, achieving 37dB.
The temperature sensor is located near the air inlet to improve response and optimize
speed.
●Easy lamp replacement mechanism (Canon replacement lamp LV-LP13)
The user can replace the lamp easily.
There is a lamp replacement lid on the rear, and the lamp can be removed just by
removing two screws.
●User cleaning air filter mechanism
The user can replace the air filter easily.
If the air filter become clogged with dust particles, it may result in internal heat build
up. To prevent this, clean the filter regularly.
* Before cleaning the air filter, stop the projector and remove the power plug from the
outlet.
4.7 Replacement Lenses
• LV-IL01, ultra wide angle lens
• LV-IL02, wide angle zoom lens
• LV-IL03, long focus zoom lens
* The projection distance is approximate.
* The ultra wide angle lens (LV-IL01) is mainly designed for rear projection and
assumed to be used with "lens shift U/D ratio of 1:1" for ultra wide angle projection.
If the lens is shifted from the center, the image may be distorted.

●Guideline for use
Use the appropriate lens for a combination of projector installation position and
screen size.
• See the figure below for the standard lens, LV-IL02 (wide angle zoom lens) and LV-
IL03 (long focus zoom lens).
Fig. 1-3
For example, use a long focus lens to project an image to a 200 type screen
installed at a distance of 12m.
• LV-IL01 (ultra wide zoom lens) can be used for front projection. If it is installed for
front projection, the projector overlaps with the center of the screen. Therefore, it
should be used for rear projection.
